How to Make Your Logo Print-Ready for Merch
By The Merch Counter team · Updated · 3 min read
A print-ready logo is large enough to print sharply (about 300 DPI at the printed size), has a transparent background, and has a version that shows up on dark fabric. For a design printed 10 inches wide, that means a file around 3,000 pixels across, usually a PNG. Most "my shirt looks blurry" problems come from a logo saved for the web, which is far too small for print.
1. Resolution: enough pixels for the printed size
Screens need far fewer pixels than printers. A logo that looks crisp on your website might be 400 pixels wide; printed 10 inches across, that's 40 dots per inch, and it will look blurry and jagged.
The target is 300 DPI at the size it will print. Our print partner, Printful, calls 150–300 DPI ideal, with 150 enough for most apparel; 300 keeps small, detailed prints crisp:
| Printed width | Pixels needed at 300 DPI | Minimum at 150 DPI |
|---|---|---|
| 3.5" (left chest) | 1,050 px | 525 px |
| 10" (full front) | 3,000 px | 1,500 px |
| 12" (large front) | 3,600 px | 1,800 px |
On The Merch Counter, 300 DPI is the target. Between 150 and 300 DPI we'll print it, but warn you it may look soft. Below 150 DPI we won't print it at that size, because it would visibly blur; you can make the design smaller or upload a bigger file. The design studio shows you this as you place your logo.
How to check your file's size: on a Mac, open it in Preview and choose Tools → Show Inspector; on Windows, right-click → Properties → Details. Look at the width in pixels.
Don't upscale. Making a small image bigger in an image editor doesn't add detail; it just makes bigger blurry pixels. You need the original file.
2. Transparent background
If your logo is a JPEG with a white background, the printer prints the white box too. That looks fine on a white shirt and wrong on everything else.
Use a PNG with a transparent background. In most design tools, export as PNG and turn off the background. Printful's print-file guide recommends PNG for exactly this reason. If you don't have one, ask your designer, or use a background-removal tool and check the edges carefully.
3. A version for dark shirts
A dark logo disappears on a black or navy shirt. You need a light version:
- A white or light one-color version of your logo
- Or a reversed version your designer made for dark backgrounds
On The Merch Counter, your brand library lets you add a dark-shirt version of each design, or generate a one-color light version, which works well for simple logos. More: How to Make Your Logo Work on Dark Shirts.
4. Simplify fine details
Very thin lines, tiny text and subtle gradients don't print or stitch well, especially:
- On hats, where embroidery can't reproduce fine detail: very small text can become illegible in thread
- At small sizes, like a left-chest print
- On textured fabrics
If your logo has a tagline in tiny type, consider a version without it for merch.
5. Get the original files
Ask whoever designed your logo for:
- A vector file (
.ai,.eps,.svgor.pdf), which can be scaled to any size - A large PNG with a transparent background, at least 3,000 pixels wide
- A light version for dark backgrounds
The checklist
- At least ~3,000 px wide for a full-front print (~1,050 px for a left-chest logo)
- Transparent background (PNG)
- A light version for dark shirts
- No hairline details or tiny text
- You own the rights to the design (if a designer made it, get that in writing)
Accepted on The Merch Counter: PNG, JPEG, WebP or SVG, up to 8MB.
