DTF Artwork Requirements: A Print-Ready File Checklist

Print-ready DTF artwork needs the correct print size, enough resolution, clean edges, and only the elements you want printed. Before uploading, check your print shop’s file requirements. Accepted formats, minimum detail sizes, and color settings vary between suppliers.

Use this checklist when preparing your own designs or reviewing customer uploads.

The quick DTF artwork checklist

Here’s how to check each one.

1. Set the actual print size

Decide how large the artwork should appear on the garment before exporting it. Keep its proportions locked when resizing so letters and logos do not stretch.

For an individual design, check whether transparent padding is included in the upload’s dimensions. A file can be 10 inches wide while the visible artwork inside it is smaller. Extra space around uploaded artwork can make the printed design smaller than intended.

Check the visible design size, not just the canvas size. For a finished gang sheet, keep the required sheet dimensions.

2. Check resolution at the final size

For raster artwork, such as PNG images and photographs, 300 pixels per inch at the final print size is a common recommendation. Suppliers often call this “300 DPI” in their upload instructions. Check your supplier’s acceptance rules before exporting.

The useful calculation is:

Required pixels = print size in inches × target PPI

At 300 PPI:

A 1,500-pixel-wide image has 300 PPI at 5 inches wide, but only 150 PPI at 10 inches wide.

Changing the resolution setting alone does not add detail. Without resampling, the pixel count stays the same. Resampling adds or removes pixels, but enlarging an image cannot reliably recover detail missing from the original.

If the file looks blurry, ask for the original artwork, export it again from the source, or reduce the print size.

3. Remove unwanted backgrounds

If you want only the design printed, remove the background before exporting. A white rectangle behind a logo can become part of the transfer. Saving a file as PNG does not automatically make its background transparent.

After removing the background, place the artwork over temporary light and dark backgrounds. Look for leftover pixels, white fringes, and missing parts of the design.

Keep white lettering and other intentional white details. Remove only the background you do not want printed.

4. Check partial transparency and faded edges

A transparent background and partially transparent artwork are different.

An empty background contains no visible design. A partly transparent shadow, glow, or faded edge still contains image information.

Suppliers may restrict these effects or require clean, fully opaque edges.

Ask the shop to review effects that fade into transparency before ordering. A color gradient made from fully opaque colors is different from a gradient that disappears into the background.

Do not remove all gradients automatically. Identify whether the effect changes color, opacity, or both, then follow the supplier’s guidance.

5. Measure thin lines and small details

Check small lettering, fine outlines, distressed textures, and isolated dots at the final print size.

There is no single minimum that applies to every DTF service. Ask your supplier for its minimum line thickness and detail size, then compare your artwork with those requirements.

For small text, inspect the thinnest parts of the letters and the gaps inside them. Font size alone does not tell you whether those details meet the shop’s limits.

If a design is close to the minimum, ask for a review or order a sample before committing to a larger run.

6. Export an accepted file

Transparent PNG is a common choice for raster artwork. Some shops also accept PDF, SVG, AI, EPS, TIFF, or PSD files. Check the shop’s accepted formats before exporting.

A PDF can contain vector artwork, raster images, or both. Saving a blurry image as a PDF does not turn it into a sharp vector design.

For vector submissions, follow the shop’s instructions for outlining text and expanding strokes.

Reopen the exported file. Check that nothing is missing, clipped, or unexpectedly changed.

7. Follow the supplier’s color instructions

Do not assume every DTF shop wants a CMYK file.

Check whether your supplier requests a particular RGB profile, a CMYK file, or the artwork’s original color profile.

Use the requested settings. If a brand color matters, ask about the shop’s color-matching service and approve a physical sample. A screen preview does not guarantee the printed result.

8. Review the finished gang sheet

Before submitting a gang sheet:

• Confirm the sheet dimensions and each design’s size.
• Count every design and check the required quantities.
• Keep artwork inside the allowed print area.
• Check for overlapping designs.
• Leave the spacing required for cutting and handling.
• Remove mockups, background layers, and unwanted notes.

Follow the supplier’s mirroring instructions. Confirm whether to submit artwork without mirroring it before exporting.

Finally, confirm whether your order includes artwork review. Some suppliers print files as submitted, so uploading successfully does not mean the artwork has been checked. Resolve anything uncertain before approving the order.
