Artwork Preparation: From Design File to Print-Ready Brief

A strong print starts before the heat press. The artwork needs enough detail, the right background, readable lettering and a size that makes sense on the actual garment. This guide helps you send a file that communicates your idea clearly and gives the studio what it needs to review the job.

1. Start with the original artwork

Find the source closest to the original design: a designer's vector export, a full-resolution illustration, or the original photograph. A screenshot of a shirt on Instagram usually contains the garment, shadows, compression and background along with the design. It can explain a concept, but it is not the same as the artwork needed to reproduce that concept cleanly.

Keep your inspiration and production files separate. Label a reference image “placement reference” or “color inspiration,” and label the file to print “artwork.” If the design needs to be redrawn, the studio can discuss that work before a production proof is approved. Do not erase a watermark and assume that makes an image suitable to reproduce; use artwork you created or have permission to use.

When sending several options, identify the version you want reviewed. A folder containing “final,” “final2” and “reallyfinal” creates avoidable uncertainty. A useful filename is Reunion_Front_10in_ApprovedCopy_v3.png. Keep a separate editable master so later changes do not depend on recovering layers from a flattened export.

2. Check resolution at the intended print size

Raster artwork is made of pixels. Its quality depends on both its pixel dimensions and how large you print it. For a practical preparation target, calculate artwork at 300 pixels per inch at the final size, then confirm the production requirements with the studio. A 10-inch-wide design at that target is 3,000 pixels wide. A 600-pixel-wide image spread across 10 inches supplies only 60 pixels per inch.

Changing a resolution field from 72 to 300 does not, by itself, restore detail missing from a small image. Resampling changes pixel data; it cannot be assumed to recover the original edges or texture. Inspect the design at the proposed output size, especially faces, lettering and fine outlines. Adobe explains the distinction between pixel dimensions, resolution and resampling in its image size and resolution documentation.

People often say “300 DPI” when discussing an artwork file. PPI describes the pixels in that image; DPI describes printer output. You do not need to master every technical term to order well. Send the dimensions in inches and the original file, and avoid repeatedly enlarging, saving and downloading a compressed copy.

3. Choose a file that preserves what matters

A file extension is not a quality guarantee. Placing a small JPEG inside a PDF does not turn it into scalable vector artwork. Likewise, a PNG may still contain a solid white background. The studio needs to inspect the contents, not just the letters after the filename.

4. Make backgrounds and edges intentional

Decide which areas should print and which should show the shirt. White can be an intentional part of a logo, lettering or illustration; it should not automatically be removed just because the garment is dark. A checkerboard may indicate transparency in an editor, but a checkerboard saved into the picture will become part of the artwork. Reopen the exported file over a contrasting background to check the result.

Look closely for a pale outline left after background removal, stray dots outside the design, or a rectangular edge around an image. Soft glows and partially transparent fades may require a different treatment for the chosen transfer system. Ask for review before approving a soft shadow that looked convincing on screen.

Thin lines and isolated distress marks need particular attention. Supplier limits vary: Transfer Express publishes specific minimum-detail and edge requirements for its UltraColor Max product in its artwork guidelines. Those are an example of product-specific requirements, not a universal specification for every DTF transfer. Keep a clean version of the design available if delicate details need adjustment.

5. Review lettering, spelling and color

Read the wording separately from the design. Check apostrophes, graduation years, team names, phone numbers, event dates and web addresses. For personalized orders, provide typed names and numbers in a table instead of asking someone to interpret handwriting. If two people share a name, include a separate order reference so their garment sizes cannot be confused.

For vector artwork, ask the designer to outline fonts in a production copy or follow the studio's agreed font-delivery process. Retain an editable original for future corrections. Outlining type protects its appearance when opened on a system without that font, but it also makes ordinary text editing less convenient.

Describe important colors in words and share any existing brand references. A phone display, a computer monitor and a physical shirt may look different. Do not treat a screen proof as an exact color sample. Confirm the requested color profile or export settings with the print provider; avoid converting back and forth between color modes without a reason. When a close match matters, discuss a physical sample before committing to a full run.

6. Build a complete proof package

Pair the artwork with the garment information: style, color, fabric if known, quantity, size breakdown and print locations. State the requested width of the visible design, not only the overall canvas. A large transparent border can make a file appear correctly sized while the printed artwork inside it is much smaller.

Attach a simple placement reference and explain anything the mockup cannot show. For example: “Small front chest design with a large back print; keep the back artwork above the hoodie pocket area shown in the reference.” If several garment sizes need different artwork dimensions, list those groups rather than leaving the decision implicit.

For a shared file link, allow the studio to view and download the actual files. Open the link in a signed-out browser before sending it to check access. Share only the assets required for the job, and avoid including unrelated personal documents in the folder.

7. Check these items before requesting production

• The file is the intended version and opens correctly.
• The visible design has a specified width and proportionate height.
• Background transparency and intentional white areas are clear.
• Small type, fine lines and distressed details have been reviewed.
• Spelling, dates, names and numbers match the written order information.
• The garment color and each print location are identified.
• The studio has confirmed any artwork preparation work and the final proof.

For help deciding how large the design should be, continue to the Artwork & Sizing Guide. When the files are together, send them through the 25/8 custom request form with a short explanation of the result you want. A clear brief gives the design room to stand out while keeping the production decisions grounded in the actual shirt.
