What File Should You Send a T-Shirt Printer?

You have a design ready and a t-shirt printer lined up. Then they ask for a vector file and you are not sure what that means or whether what you have actually qualifies.

This happens constantly. Here is a straight answer to what t-shirt printers actually need, why they need it, and what to do if you do not have the right file.

The Short Answer

For most t-shirt printing methods, you need a vector file. The formats printers most commonly accept are AI, EPS, or a vector-based PDF. SVG is sometimes accepted depending on the printer's software.

If you only have a PNG or JPG, that file will work for some printing methods but not all, and even when accepted it may produce a lower quality result than a proper vector.

Why T-Shirt Printers Ask for Vector Files

Different t-shirt printing methods work differently, but the most common ones all benefit from vector artwork.

Screen Printing

Screen printing is the most widely used method for bulk t-shirt orders. Each color in the design is printed separately through its own screen. The screen is made by exposing a template from the artwork file.

For this to work, the printer needs clean, separated colors with no gradients, no semi-transparent areas, and no blurry edges. A vector file with flat color fills makes this easy. A PNG, especially one with soft edges or anti-aliasing, makes it difficult or impossible.

If you send a PNG to a screen printer, they will either ask for a vector file, charge you an art fee to convert it, or run it and produce a result that is not as sharp as it should be.

Heat Transfer Vinyl (HTV)

HTV involves cutting the design from colored vinyl and heat-pressing it onto the shirt. The cutting machine follows paths, not pixels. You need a clean SVG or similar vector format with well-structured cut paths.

A PNG submitted for HTV will be auto-traced by the cutting software, which often produces jagged or incorrect cut lines, especially for logos with text or fine details.

DTG (Direct to Garment)

DTG printing works more like an inkjet printer and can handle raster files. A high-resolution PNG at 300 DPI with a transparent background is usually the minimum for DTG. This is one of the few t-shirt methods where a PNG can genuinely work.

That said, starting from a vector and exporting a high-resolution PNG gives you sharper edges on text and clean shapes compared to a raster PNG that has been resized.

DTF (Direct to Film)

DTF is similar to DTG in that it accepts raster files. A PNG at 300 DPI with a transparent background is the standard. Again, vector-sourced exports produce better results than native raster files, particularly for logos with text.

What If You Only Have a PNG?

For screen printing or HTV, a PNG alone will not work. You need a vector file.

For DTG or DTF, a PNG can work if it is high enough resolution. As a rough guide, the design should be at least 300 DPI at the actual print size. A logo that is only 400 pixels wide needs to be significantly larger before it is usable for print.

If you only have a small PNG and need screen printing or HTV, the most practical path is to have the logo redrawn as a clean vector file by a professional vectorization service. The result looks identical to your original but works for any printing method at any size.

Do not use an online auto-converter and assume the result is production-ready. Auto-traced files frequently have messy paths, incorrect color counts, and stray shapes that screen printers cannot work with. A proper manual trace is what actually solves the problem.

What About Color Counts?

For screen printing, every color is a separate screen and a separate cost. A two-color design is cheaper to print than a five-color design.

When you prepare your artwork for screen printing, the colors should be flat and clearly defined. No gradients. No drop shadows. No semi-transparent layers. If your logo has a gradient in it, it needs to either be removed for screen printing or converted to a halftone effect, which requires a designer's input.

When sending your file, tell the printer how many colors the design contains and what those colors are. Providing Pantone references for your brand colors means the printer can match them accurately rather than making their own judgment.

What the File Should Look Like Before You Send It

A t-shirt ready vector file should have:

• Clean, smooth paths with no jagged edges
• Flat, solid color fills with no gradients or soft shadows (for screen printing and HTV)
• Colors clearly separated with each color on a logical layer or group
• Text converted to outlines so no font installation is needed
• No stray shapes or hidden elements
• Correct file format for the printing method (AI or EPS for screen printing, SVG for HTV, PNG at 300 DPI for DTG or DTF)

Frequently Asked Questions

Can I send a Canva export to a t-shirt printer?

Canva exports PNG or PDF. For DTG printing, a high-resolution PNG from Canva sometimes works. For screen printing or HTV, you will need a proper vector file. Canva's PDF export is not a true vector file in most cases, and logos within Canva designs are typically raster elements regardless of the export format.

The printer said they will convert my file for a fee. Should I do that?

You can, but the quality of the conversion varies. Some printers do a proper manual redraw. Others use an auto-tracer and produce a file with the problems described above. Getting your own clean vector file gives you something you can use with any printer going forward.

What if my logo has a photo in it?

Photographic elements cannot be vectorized in the traditional sense. Screen printing handles this with a process called simulated process printing, which uses halftone dots to approximate photographic tones. This is more expensive and requires specific artwork preparation. For most apparel printing, simpler designs with flat colors produce better and more affordable results.

My design has ten colors. Is that a problem?

For screen printing, yes. Each color is a separate screen and a significant cost. Most screen printers recommend keeping designs to six colors or fewer for cost-effective production. For DTG or DTF, color count is not a cost issue.

Do I need to set up my artwork at a specific size?

Yes. Know the print area size before submitting. A chest print is typically around 10 to 12 inches wide. A full front can be larger. Build or size your artwork to the actual print dimensions before sending.
