The best file format for screen printing is a vector file: AI, EPS, or a PDF saved with live vector shapes. If all you have is a PNG, it can still work when it's at least 300 DPI at the size it will print and has a transparent background. A small JPG pulled off a website usually can't be used as-is, but it can be rebuilt.
That's the short version. The longer version is what this post covers, because "what file format do you need for screen printing" is the question we get before almost every first order at Conquer Printing, and the honest answer depends on the print method, the number of colors, and what you're starting with.

Why screen printing cares about file type
Screen printing lays one color of ink at a time through a mesh screen. Each color needs its own screen, and each screen is made from a black-and-white film of just that color's shapes. To make that film cleanly, the shop needs sharp, hard edges and flat colors.
A vector file describes shapes with math: a circle is a circle at any size. A raster file (PNG, JPG, GIF) is a grid of pixels. Blow a raster up and the grid gets bigger, so the edges turn to stair-steps. Vector files skip that problem, and that's the whole reason printers ask for them. Adobe has a decent plain-language explanation of raster vs. vector if you want the technical background.
The file types, ranked
Here's how the common formats stack up for a screen print job.
| File type | Works for screen printing? | What to know |
|---|---|---|
| AI (Adobe Illustrator) | Best | Vector, editable, separates cleanly into colors |
| EPS | Best | Older vector format, still opens everywhere |
| Good, if vector | Only works if it was exported from vector art, not a flattened photo | |
| SVG | Good | Vector, common from web and Canva-style tools |
| PNG | Sometimes | Needs 300 DPI at print size and a transparent background |
| JPG | Rarely as-is | Compression fuzz around edges, no transparency |
| Screenshot or phone photo | No | Rebuild the artwork from scratch |
The PDF row trips people up more than any other. A PDF is a container. It can hold crisp vector shapes or a low-res picture wearing a PDF costume. If you can zoom in to 800% and the edges stay sharp, it's vector. If it goes soft, it isn't.
Can you screen print a JPG or PNG?
Yes, sometimes. A PNG made at the right size is fine for a simple one or two color design. Say you've got a logo exported at 3,600 pixels wide and it prints 12 inches across the chest. That's 300 pixels per inch, which is the number we look for.
A JPG is harder. JPGs compress by smudging detail, and that smudge shows up as a halo of off-color pixels around every edge. Those halos become ragged ink edges on the shirt. We can often clean a decent JPG. We can't clean one that's 400 pixels wide, and no amount of upscaling adds detail that isn't there.
Some rules of thumb that hold up in the shop:
- Bigger than you think. Export at the final print size or larger, never smaller.
- Transparent background, not a white box. A white box can print as a white rectangle on a dark shirt.
- No screenshots of a logo from Instagram or a website header.
- Text should be outlined or supplied with the font file, or it may swap to a default typeface.
Vector vs. PNG for t-shirts
For screen printing, we'd steer you to vector every time you have the choice. It's the only format that lets the printer resize the art for a youth small and a 3XL without redrawing it. Order a hoodie with a left-chest logo and a big back print of the same design, and a vector file covers both.
The exception is photographic or heavily shaded art. A vector can't hold a photo. For that kind of artwork, the print method matters more than the file format, and you're usually better off with DTF or DTG printing, which reproduces gradients and photo detail directly. Those methods still want a high-resolution PNG, again at 300 DPI at print size. Our comparison of screen printing, embroidery, and DTF walks through which one fits which design.
Embroidery is a different animal
Here's where people get burned. A vector logo is not an embroidery file. Embroidery machines don't read shapes, they read stitch instructions: where the needle goes, in what order, at what angle. Turning artwork into those instructions is called digitizing, and it's done by a person with specialized software, not by a converter button.
So for embroidery, you send the same clean logo artwork you'd send for screen printing, and the shop digitizes it. Also, embroidery is the wrong call for tiny detail. Thread has thickness, so a 1/8-inch line of text can turn into mush. If your logo has fine print or gradients, we'll say so up front and suggest a simplified version for stitching.
What if you only have a bad file?
Most people do. A lot of small businesses have a logo that lives as a Facebook profile picture and nothing else. That's normal, and it's fixable.
Free design support is included at Conquer Printing, so send whatever you've got and we'll look at it. Depending on the file, one of three things happens. If it's clean enough, we use it. If it's close, we tidy it up. If it's too small or too blurry, we work with you on rebuilding it as a vector, which is the fix you want anyway, since you'll own a proper file for every future order, from shirts to banners to a vendor booth setup.
The one thing that can't be salvaged is a design whose only copy is a tiny, low-quality image, and where the original designer can't be found. Even then, a redraw from the image is usually possible. It just takes longer.
What to send with your file
A file alone isn't quite an order. These details help us quote and print faster:
- The garment type and how many pieces you need.
- Where each design goes: left chest, full front, back, sleeve.
- Your ink colors, ideally with Pantone numbers if your brand has them.
- Your deadline. Standard turnaround is 7 to 10 business days, and rush jobs of 5 days or less start at an additional 20%.
There are no minimums, so a run of 12 is as welcome as a run of 500.
Common Questions
What is the best file format for screen printing?
Vector files are best: Adobe Illustrator (AI), EPS, or a PDF that was exported from vector artwork. They scale to any size without losing sharpness and separate cleanly into individual ink colors. Most shops, including Conquer Printing, will also work from a high-resolution PNG when a vector isn't available.
What resolution do I need for screen printing artwork?
For raster files like PNG, you need 300 DPI at the actual print size. A design that prints 10 inches wide should be about 3,000 pixels wide. Files that are lower than that print with soft or jagged edges, and upscaling them later doesn't restore the missing detail.
Can I send a JPG to a screen printer?
You can send one, and a good printer will look at it. A large, clean JPG of a simple design can sometimes be used after cleanup. A small or heavily compressed JPG usually needs to be redrawn as a vector before it can be printed well.
Do I need a vector file for embroidery?
Not exactly. Embroidery needs a digitized stitch file, and the shop creates that from your artwork. Clean vector or high-resolution art makes digitizing faster and more accurate, but the vector itself is never what the machine reads.
What if I don't have my logo file at all?
Ask whoever designed it first, since they often have the original AI or EPS file. If that's a dead end, a shop can rebuild it from a clear image. Conquer Printing includes design support at no charge, so start by sending what you have.
The bottom line
Vector is the file to ask for, PNG at 300 DPI is the fallback, and a small JPG is a starting point for a redraw, not a print file. If you're unsure which one you have, don't pay a freelancer to find out. Start a quote request, send us the file, and we'll tell you what it needs. If it turns out to need a rebuild, do it once as a vector and every order after that starts on solid ground.
