DTF Transfers FAQ
Straight answers about custom DTF transfers, gang sheets, artwork, ordering, wholesale printing, application, care, and troubleshooting—so you can print with confidence.
General Questions
DTF stands for direct to film. A DTF transfer is a full-color design printed onto a coated carrier film with specialized inks, white ink, and a heat-activated adhesive. The finished transfer is placed on a garment and applied with a heat press. Once pressed and peeled correctly, the printed design remains bonded to the fabric.
DTF is popular because it handles detailed artwork, gradients, small production runs, and multicolor designs without separate screens for each color. It also works on a broad range of garment colors and fabric blends. DTFZoo supplies ready-to-press transfers; you provide the garment and apply the transfer using the instructions appropriate to your order.
Your artwork is printed in color onto transfer film, backed with white ink, coated with adhesive powder, and cured. During application, heat and pressure activate the adhesive and bond the ink layer to the garment fibers. After the carrier is peeled according to the film instructions, a short finishing press helps settle the print and improve its surface feel.
The result depends on the entire workflow: clean high-resolution artwork, correct print production, an accurate heat press, even pressure, the correct peel method, and proper garment care. A transfer cannot compensate for blurred artwork or insufficient pressure, so checking the file and testing the press are important parts of reliable production.
DTF prints full-color artwork as one ready-to-press transfer, so there is no weeding and no separate vinyl layer for every color. Compared with traditional screen printing, DTF does not require a separate screen and setup for each ink color, which makes it practical for detailed designs, varied artwork, and smaller quantities. Screen printing can still be excellent for very large runs with simple spot-color graphics.
Heat-transfer vinyl is useful for names, numbers, and simple shapes, while DTF is generally more efficient for complex art, gradients, photographic detail, and many colors. The best process depends on the design, quantity, fabric, finish, and production workflow—not a single method being best for every job.
DTF transfers are commonly applied to cotton, polyester, cotton-poly blends, and many other heat-tolerant textiles. Unlike sublimation, the garment does not need to be white or high in polyester because the transfer includes a white ink base. That makes DTF useful for both light and dark garments.
Always check the garment manufacturer’s heat limit before pressing. Heat-sensitive synthetics, coated performance fabrics, waterproof materials, nylon, textured fabrics, and garments with dye-migration risk may require lower temperatures, barrier testing, or a specialized transfer. Seams, zippers, pockets, and thick panels can also prevent even pressure. Test an inconspicuous sample when the fabric or finish is unfamiliar.
A properly produced and applied DTF transfer is designed to remain vibrant and flexible through repeated wear and washing. Actual life depends on garment fabric, artwork coverage, press accuracy, application pressure, finishing press, detergent, wash temperature, drying method, and normal abrasion. Large solid areas can feel and behave differently from designs with more negative space.
For the best durability, follow the supplied application instructions, verify your heat press temperature with an independent thermometer, use even pressure, and complete the recommended finishing press. Wash the garment inside out in cool water with a mild detergent, avoid bleach and fabric softener, and tumble dry low or hang dry. Do not iron directly over the printed surface.
Shipping
Shipping time begins after production is complete and the carrier accepts the package. The delivery estimate depends on the service selected at checkout, destination, carrier network, weather, holidays, and other conditions outside the print queue. Production turnaround and shipping transit are separate time periods, so add both when planning a garment deadline.
Use the current delivery estimate shown at checkout and track the package after its first carrier scan. A tracking number may appear before movement because labels can be generated during fulfillment. For events or customer commitments, order early enough to inspect and press the transfers before the deadline rather than scheduling delivery for the day they are needed.
DTFZoo advertises nationwide shipping to all 50 states. Available carriers, service levels, costs, and estimated delivery dates are calculated from the order and destination during checkout. Verify the full shipping address, apartment or suite number, postal code, and recipient details before placing the order because custom products may move into production quickly.
If you are shipping to a commercial location, confirm receiving hours and whether the carrier can access the building. For time-sensitive work, choose an appropriate tracked service and allow a buffer for carrier exceptions. A faster shipping method does not automatically change production speed unless a separate rush-production option is confirmed.
First review the tracking history, delivery photo, address, household members, mailroom, and nearby safe locations. If the carrier shows a delay, follow its latest estimate before treating the shipment as lost. For damage, photograph the unopened package, shipping label, interior packaging, complete sheet, and close-up defects before discarding anything.
Contact DTFZoo with your order number and evidence as soon as possible. Keep the packaging and transfers available while the claim is reviewed. Carrier loss, transit damage, fulfillment errors, and artwork or application problems require different evidence, so a clear description helps route the issue correctly. Follow the current posted claim window and support instructions.
Wholesale
Yes. DTFZoo publishes volume-based wholesale pricing for gang-sheet printing without requiring a membership fee. The pricing tiers reward larger total sheet volume, making them useful for apparel brands, print shops, resellers, event producers, and decorators outsourcing overflow. Current thresholds and rates should always be confirmed on the DTFZoo homepage pricing section before quoting your own customer.
Wholesale value comes from more than the lowest unit price. Plan artwork, sheet utilization, production timing, quality checks, packaging, replacement allowance, and shipping when calculating the real cost per transfer. The wholesale DTF transfer guide explains how gang sheets support an efficient purchasing workflow.
Standardize the files before building sheets: final dimensions, resolution, transparency, color profile, naming, and quantities. Group similar production work logically and keep a manifest that identifies each design, size, sheet, and customer. Order and press a representative sample when the artwork, garment, or color tolerance is new. That small qualification step is much less expensive than discovering a systematic issue after a full run.
Allow enough time for production, shipping, receiving inspection, cutting, pressing, and replacements. For unusually large or deadline-sensitive orders, contact DTFZoo before checkout to confirm current capacity and file-transfer requirements. Do not split one job into duplicate orders unless support recommends it, because separate orders may be produced or shipped independently.
Archive the approved source file, exported print file, exact dimensions, color profile, order details, garment type, press settings, and a pressed reference sample. Reuse the same final artwork rather than recreating it from screenshots or compressed downloads. Keep version numbers in filenames so revised artwork cannot be confused with the approved production file.
Some variation can occur across monitors, garment lots, materials, and production batches. For critical brand work, compare a new physical sample with the approved reference before pressing the entire run. Maintain your heat press with verified temperature and pressure, since changes during application can look like printing inconsistency even when the transfer itself is within tolerance.
Application
Confirm the instructions supplied with the transfer, because film and adhesive systems can require different temperatures, times, pressures, and peel methods. Preheat the press, verify its actual platen temperature, prepare a flat pressing surface, and briefly pre-press the garment to remove moisture and wrinkles. Position the transfer with the printed side against the fabric and the carrier facing up.
Press using the specified settings and even pressure. Peel at the instructed temperature and speed, then complete the recommended finishing press with suitable cover material. Let the garment cool before stretching or stacking it. Test one transfer first whenever the garment, press, or transfer batch is unfamiliar.
Use the pressure level specified with the transfer, typically described in relative terms such as medium or firm. The actual force varies by press design, platen size, garment thickness, and adjustment system, so a knob position on one machine does not translate directly to another. What matters is uniform contact across the complete artwork.
Seams, collars, pockets, zippers, and buttons can hold the platen away from part of the transfer. Use an appropriate pressing pillow or smaller platen to isolate the print area without creating a new pressure ridge. If edges repeatedly fail while temperature and time are correct, uneven or insufficient pressure is a likely cause. Excessive pressure can also affect texture and garment marks, so test methodically rather than simply increasing force.
The terms describe the carrier temperature when it should be removed. A hot-peel film is removed soon after the press opens, a warm-peel film rests briefly, and a cold-peel film cools substantially before removal. The correct method is determined by the transfer film and adhesive—not personal preference or a generic DTF rule.
Peeling too early can lift ink that has not stabilized; peeling too late on a system designed for hot release can also change handling. Follow DTFZoo’s supplied instructions for that order. Peel smoothly at a low, consistent angle while watching the edge. If any part lifts, stop, lay the carrier back down, repress using the recommended troubleshooting method, and allow the appropriate cooling period before trying again.
Allow the applied transfer to rest for the period stated in the care instructions before its first wash. Turn the garment inside out, wash in cool water on a normal or gentle cycle, and use a mild detergent. Avoid chlorine bleach, harsh stain treatments on the print, and fabric softener, which may affect the garment or transfer over time.
Hang drying is gentle; if using a dryer, choose low heat and remove the garment promptly. Do not dry clean unless the transfer and garment have been tested for that process. Never place a household iron directly on the printed surface. If ironing the garment is necessary, turn it inside out or protect the transfer and use the lowest appropriate heat.
Choose size based on the garment dimensions, wearer, print location, artwork proportions, and the visual result you want. The same width can look very different on an adult large shirt, youth shirt, hoodie, tote, or left-chest position. Measure the printable area rather than relying only on the garment label.
Use DTFZoo’s shirt transfer sizing guide as a practical starting point, then print a paper proof at 100% scale and place it on the actual garment. Check alignment relative to the collar, center line, seams, and pockets. Record approved measurements for repeat production so operators place every transfer consistently.
Heat Press
Use the exact temperature, dwell time, pressure, peel, and finishing instructions supplied with your DTFZoo transfers. DTF products do not all share one universal recipe, and the correct settings can change with the film, adhesive, garment material, and dye-migration risk. Generic settings found online may be wrong for the transfer in your hand.
Verify the platen temperature with a reliable heat-strip test or infrared instrument used correctly, because a press display can be inaccurate or uneven. Start with one test garment, inspect adhesion and surface finish, and change only one variable at a time. Document the successful settings for the press, platen, garment, and transfer batch.
A heat press is strongly recommended because it delivers controlled temperature, time, and even pressure across the complete design. Household irons cycle temperature, have steam holes, provide a small uneven contact area, and make consistent pressure difficult. A transfer may appear attached while still having weak adhesive activation that fails during peeling or washing.
Do not promise production-quality results from an iron unless DTFZoo’s instructions specifically support that method. For reliable customer work, samples, and repeat orders, use a maintained heat press with a flat platen. If you do not own one, consider a local pressing service rather than risking the garment and transfer.
A short pre-press helps remove surface moisture and wrinkles, creates a flatter print area, and reveals obstacles that could interfere with pressure. Moisture can turn to steam during application and contribute to inconsistent bonding. The pre-press also lets you position the garment accurately before placing the transfer.
Follow the garment’s heat tolerance and avoid over-preheating sensitive polyester or coated fabrics. After pre-pressing, let excess steam escape, smooth the garment without stretching it, and position the transfer on the prepared area. If seams or raised construction prevent a flat surface, use the proper platen or pressing accessory rather than expecting the pre-press to solve uneven pressure.
The finishing press occurs after the carrier is removed. It helps settle the transfer into the fabric texture, supports complete adhesive bonding, and can produce the intended surface finish. Use the cover material, time, temperature, and pressure specified in the application instructions because parchment, silicone sheets, and textured finishing sheets can produce different results.
Do not assume a longer or hotter second press is better. Excess heat can mark garments, encourage dye migration, alter sheen, or affect the transfer. Complete one controlled test, allow it to cool, and inspect the edges and surface. Record the successful finishing method alongside the primary press settings for consistent repeat work.
Troubleshooting
Lifting usually points to the wrong peel temperature, insufficient pressure, inaccurate heat, too little time, moisture, or uneven contact caused by seams and garment construction. Stop peeling as soon as you see the design lifting. Lay the carrier back into position without shifting it, protect the area, and repress according to the supplied troubleshooting guidance.
Let the transfer reach the correct peel temperature before trying again, then peel slowly at a low angle. If the problem repeats, verify the press temperature and check pressure across the full platen. Test on a flat sample garment. Photograph the transfer and record settings before contacting support so the cause can be evaluated accurately.
Cracking can result from incomplete adhesive activation, uneven pressure, excessive heat, overstretching, harsh laundering, high dryer temperatures, or an artwork shape with large solid coverage. First confirm that the press is accurate and that both the primary and finishing presses followed the supplied instructions. Check whether cracks align with seams, fabric texture, or areas that received less pressure.
Wash inside out in cool water and dry on low heat. Avoid stretching the print while hot. If the issue affects multiple correctly applied transfers, document the order, garment, settings, care process, and clear photos before contacting support. That evidence helps separate application, garment, care, and production causes.
DTF transfers are designed to have useful flexibility, but they are not infinitely elastic. The perceived stretch depends on ink coverage, design geometry, adhesive, fabric, application, and whether the garment is stretched beyond normal wear. Large solid rectangles resist movement more than artwork broken up with negative space and smaller elements.
Do not perform an aggressive stretch test while the transfer is hot; allow it to cool and stabilize first. For highly elastic garments, test the exact fabric and print size before production. If maximum flexibility is important, reduce unnecessary solid backgrounds and avoid placing rigid artwork across areas that undergo extreme expansion.
Check the garment’s heat tolerance and verify that the press is not hotter than its display. Excess temperature, long dwell time, excessive pressure, repeated pressing, and inappropriate cover sheets can create shine or platen outlines. Polyester and treated performance fabrics deserve extra testing because heat can change their surface or trigger dye migration.
Use the recommended settings, press only the intended area, and consider an appropriate pressing pillow or protective material when garment construction creates marks. Test an inconspicuous sample and let it cool before judging; some moisture or temporary press marks dissipate. If the fabric cannot tolerate the required process, choose another garment or a transfer system designed for that substrate.
A visible box usually means the uploaded artwork contained a solid background instead of transparency. White or colored halos can come from incomplete background removal, anti-aliased pixels left from the original background, a white matte setting during export, compression artifacts, or a white underbase showing around misaligned edge pixels.
Open the original file over contrasting light and dark backgrounds and inspect at high zoom. Remove unwanted pixels from the source, refine edge colors, and export a fresh transparent PNG at final size. Do not erase the background from a low-resolution JPEG and expect perfectly clean edges. Rebuilding from the original vector or layered artwork usually gives the best result.
Store transfers flat in a clean, dry, temperature-stable place away from direct sunlight, humidity, dust, and extreme heat or cold. Keep the printed surface protected by the carrier and avoid stacking it against rough materials. Do not fold or tightly roll small transfers, because creases can damage the print or interfere with even contact during application.
Use protective sleeves or clean paper between sheets when appropriate, label the artwork and receipt date, and handle transfers with dry hands. Before pressing material that has been stored for a long period or exposed to unusual conditions, test one transfer on the intended garment. Follow any shelf-life guidance supplied with the order.

Ordering
Choose the order path that matches your file. If you have individual designs and want to arrange them online, use the Gang Sheet Builder. If your full gang sheet is already sized and print-ready, use the Upload Gang Sheet option. Select the correct sheet size or length, review the artwork at final dimensions, add the item to your cart, and complete checkout.
Before ordering, confirm that transparent areas are actually transparent, small details are printable, the sheet dimensions match the selected product, and no artwork extends beyond the canvas. Your order enters production based on the submitted file, so a final check prevents avoidable scaling, cropping, or background problems.
DTFZoo advertises no minimum order, so you can begin with a single available sheet or transfer configuration instead of committing to a large run. For very small designs, placing multiple copies on one gang sheet is usually more economical than leaving unused film. You can include repeated designs, different sizes, or unrelated customer jobs on the same sheet when their production requirements match.
Check the current product options and pricing in the DTFZoo shop, because the minimum selectable sheet dimensions—not the number of individual graphics—determine the smallest purchasable format. A small test order is also useful when pressing an unfamiliar garment, checking artwork detail, or qualifying a new production workflow.
The builder is for arranging individual transparent artwork files on a gang-sheet canvas. You can upload designs, duplicate them, resize them, and organize the layout before ordering. It is the easier route when you do not already have a complete sheet file or want to maximize the available space visually.
The upload option is for a finished gang sheet created in software such as Photoshop, Illustrator, Affinity, or another design tool. Your uploaded sheet should already have the correct final width, height, resolution, transparency, spacing, and orientation. DTFZoo prints the submitted layout rather than rebuilding it. If you are unsure about physical sizing, consult the DTF shirt sizing guide before completing either option.
Contact DTFZoo immediately if you discover a mistake after checkout. Fast production means an order may move to preflight or printing quickly, so changes cannot be guaranteed once production has started. Include your order number, the affected sheet, and a precise description of the requested correction. Do not submit a second file without support confirming how it will be matched to the order.
The safest approach is to treat checkout as final approval. Review spelling, transparency, orientation, dimensions, duplicate counts, margins, and selected sheet length before paying. If production has not begun, support can advise whether a replacement file or cancellation is possible under the current order policy. If printing has started, a corrected order may be required.
Custom transfers are produced from customer-supplied artwork and generally cannot be restocked like an unused retail item. If you believe DTFZoo made a production error, contact support promptly with the order number, clear photographs of the complete affected transfer, close-ups of the issue, and—when relevant—your press settings and application steps. Keep the transfer, carrier, packaging, and garment until the review is complete.
Reprint or refund eligibility depends on the current posted policy and the cause of the problem. Artwork errors, incorrect dimensions, low-resolution files, unsupported garment conditions, or application mistakes are different from verified printing defects or fulfillment errors. Providing complete evidence helps support distinguish the cause and resolve eligible claims faster.
Artwork
A high-resolution PNG with a transparent background is the safest general format for raster DTF artwork because it preserves transparency and final pixel dimensions. The builder and upload product may support additional formats or impose different file-size limits, so always follow the file selector and current instructions shown on the specific product page rather than assuming every design format can be processed.
Do not rename a file extension to make an unsupported file appear compatible. Export a fresh production file from the original design software. Flatten effects carefully, outline or rasterize fonts when appropriate, remove hidden objects, and reopen the exported file to verify transparency and dimensions. Keep an editable source file separately in case you need to correct or resize the design later.
Prepare raster artwork at 300 pixels per inch at the final physical print size whenever possible. A 12-inch-wide design should therefore contain about 3,600 pixels across. Resolution labels alone are not enough: changing a 72 PPI label to 300 PPI without adding real detail does not improve a low-resolution image. Inspect the artwork at 100% and look for jagged edges, compression blocks, blur, and halos.
Vector source artwork can scale cleanly, but transparent PNG exports still need enough pixels at the intended dimensions. Avoid enlarging small web images, screenshots, or social-media downloads. If the source is marginal, print it smaller, recreate it from original elements, or obtain a higher-resolution file before ordering.
Transparency tells the print workflow which areas should contain no ink or adhesive. If a file has a white rectangular background, that white area may print as part of the transfer—even when the design is intended for a white shirt. A transparent PNG preserves cutout shapes, interior openings, and negative space without requiring manual background removal during production.
Before uploading, view the file over both light and dark checkerboard backgrounds. Look for faint boxes, leftover pixels, white fringes, partially erased areas, and soft shadows that extend farther than expected. Do not use JPEG when transparency is required because JPEG always has a solid background and can introduce compression artifacts around edges.
Follow the color-profile guidance on DTFZoo’s current upload instructions. Many DTF workflows accept RGB files and convert them through a printer-specific RIP profile, while the physical printer ultimately uses CMYK plus white ink. Converting repeatedly between RGB and CMYK can shift saturated colors and does not guarantee a closer match.
Use a consistent embedded profile, work on a calibrated display when color matters, and avoid colors that are impossible to reproduce in print, such as extremely bright backlit neons. The shirt color, white underbase, ink set, film, curing, and heat application all affect appearance. For brand-critical colors, order a physical test rather than approving solely from a phone or uncalibrated monitor.
Very fine isolated lines, tiny dots, distressed specks, and narrow negative gaps can become fragile during printing, powdering, peeling, or repeated washing. There is no universal minimum that works for every design because the final print size, contrast, adhesive coverage, fabric texture, and surrounding artwork all matter. As a practical starting point, avoid hairline strokes and enlarge critical details until they remain clearly visible at actual size.
Inspect the file at 100% and print a paper proof at final dimensions. Small light-colored elements on a dark garment are especially dependent on a clean white underbase. If a detail is essential to the design, make it deliberately robust instead of relying on the printer to preserve a nearly invisible pixel-width feature.
Judge text by its printed height and stroke thickness, not only the point size shown in design software. A bold, open sans serif can remain readable smaller than a thin script with tight counters. Print the design on paper at 100% scale, view it from normal garment distance, and check that enclosed spaces in letters such as a, e, o, and R remain open.
For dependable apparel production, avoid extremely thin fonts, tiny legal copy, closely spaced outlines, and narrow knockout text. Convert fonts to outlines or rasterize them in the final export so missing font files cannot change the result. If the wording matters, prioritize readability over fitting more characters into the same area.
Gang Sheets
A gang sheet is one larger print layout containing multiple transfer designs. The sheet can include repeated logos, different graphics, several sizes of the same design, or artwork for multiple jobs. After printing, the individual transfers are cut apart before application. The purpose is to use the available film efficiently and reduce the cost per design.
Gang sheets work best when every graphic is already clean, correctly sized, and separated enough to cut safely. You can arrange artwork online with DTFZoo’s Rolling Gang Sheet Builder or create the complete canvas yourself and use the upload option. The custom DTF gang sheet guide provides additional planning advice.
Leave enough clear space to cut between graphics without touching ink, adhesive, or soft effects such as glows and shadows. The best spacing depends on whether you use scissors, a rotary cutter, or an automated finishing method. Crowding artwork edge to edge may save a small amount of film but increases the chance of damaging nearby transfers.
Keep all artwork inside the builder or upload canvas and respect any safe-area guidance shown on the product. Check transparent effects carefully because their visible pixels may extend beyond the obvious shape. Use a consistent gap throughout the sheet, zoom in before approval, and avoid placing critical elements directly on the outside edge.
Yes. A gang sheet can contain different graphics, multiple customers’ artwork, and several physical sizes as long as everything fits within the selected sheet and meets the same production requirements. This makes gang sheets useful for left-chest logos, full-front designs, youth sizes, labels, and test prints in one order.
Labeling is not printed unless you include it as artwork, so keep an external layout reference if similar versions might be confused after cutting. Verify every item’s dimensions individually; scaling the entire sheet later can make all transfers the wrong size. Use the DTF transfer sizing guide as a starting point and adjust for the actual garment and artwork proportions.
Start with the largest designs, then fill open areas with smaller logos, labels, or extra copies you are likely to use. Rotate artwork only when its orientation on film will not confuse cutting or application. Nest irregular shapes carefully while maintaining a safe cutting gap. Remove unused transparent canvas around each individual file before adding it to the sheet.
Do not shrink designs below their intended garment size merely to increase quantity. A tightly packed sheet that produces unusable transfers is not efficient. Review the entire canvas at final size, count repeated designs, confirm no objects overlap, and leave practical cutting paths. For more workflow guidance, read DTFZoo’s wholesale DTF and gang sheet guide.
A gang sheet is generally supplied as the combined sheet you arranged, not as individually trimmed transfers, unless the selected product explicitly includes a cutting service. Plan to separate the graphics with clean scissors, a rotary cutter, or another appropriate tool before pressing. Cut through the clear carrier area and avoid nicking the printed design.
Keep the carrier with each transfer until application so the printed surface remains protected. If you prepare transfers for different customers or garment locations, sort and label them after cutting. Check the current product description or contact DTFZoo before ordering if individual cutting is operationally important; do not assume finishing services that are not stated on the selected product.
Printing
DTFZoo advertises a typical 1–2 day production turnaround. Production time is separate from carrier transit time and begins according to the current order cutoff, payment status, and file readiness. Orders that require clarification, contain upload problems, or are placed during unusually high volume may need additional time.
Use the latest turnaround displayed on the product or checkout page when planning a deadline, because operational conditions can change. If you have a fixed event date, allow time for production, carrier pickup, transit, application, and a contingency for reprints or shipping exceptions. A shipping label or tracking number may be created before the carrier records its first physical scan.
Do not assume same-day production unless a rush option is explicitly shown as available for your product, quantity, order time, and fulfillment method. DTFZoo’s standard public promise is fast production, but same-day eligibility can depend on cutoff times, artwork readiness, capacity, sheet volume, payment clearance, and whether shipping or local pickup is involved.
If timing is critical, contact support before ordering and provide the exact sheet quantity, dimensions, required delivery date, and destination. Rush production shortens the manufacturing queue; it does not guarantee carrier transit or delivery. Place deadline-sensitive work as early as possible and avoid submitting files that may require clarification.
Digital DTF printing reproduces color through a profiled ink and RIP workflow, but an exact match to every screen, Pantone swatch, or previous printing process cannot be assumed. Monitors emit light; printed ink reflects light. Fabric color, white underbase, artwork profile, ink limits, curing, press temperature, and finishing can all affect the final appearance.
Use consistent color values and an embedded profile, avoid judging critical colors on an uncalibrated phone, and provide clear reference information when support accepts it. For brand-critical work or a large run, order and press a physical test before committing the full quantity. Evaluate the sample on the actual garment under the lighting where it will be viewed.
Yes. A DTF printer uses white ink behind the color layer, which allows white elements and bright colors to remain visible on dark garments. That white underbase is one of the main reasons DTF works across a wide range of shirt colors without requiring the garment to be white.
Transparent areas receive no intended artwork, so do not confuse transparency with white. If a design needs a white shape, include that shape as visible white artwork; if the shirt should show through, make that area transparent. Very small white details and thin knockout areas should be made robust enough to print and adhere reliably.
