Send a PNG with a transparent background at the final print size, 300 DPI, RGB color mode, with the canvas trimmed and no semi-transparent pixels. If your logo is vector art, a PDF, SVG, or EPS works just as well. Confirm your placement size (say, 3–4 inches for a left chest logo or 10–12 inches for a full front) and always ask for a proof before your order goes into production.
TL;DR:
- Export your artwork as a PNG with transparent background at 300 DPI and at the exact print size to ensure high-quality results.
- Check your file for stray pixels, convert fonts to outlines, and name it clearly to prevent delays or quality issues during printing.
- For dark shirts, ensure your background is fully transparent to avoid white halos and test edges at high zoom levels for see-through artifacts.
- Different printing methods require specific file types and designs; simplify artwork for embroidery and use color separations for screen printing.
- Confirm you hold the rights to any logos used and prepare separate files for multiple placements to streamline the printing process.

Production-ready preflight: file formats, DPI, canvas, and naming
Getting your file right the first time saves you from back-and-forth emails and reprint fees. Here’s what to check before you upload anything.
Use PNG with a transparent background for raster artwork like photos or hand-drawn designs. For anything built from shapes, letters, or logos, export as SVG, EPS, or PDF so it scales to any size without losing quality. PNG with transparency is treated as the standard for DTF work, and JPG files should be avoided entirely since they can’t hold transparency and will print a solid background block.
Set your resolution to 300 DPI at the size you actually intend to print, not the size on your screen. A file that looks sharp on a phone can look blurry once it’s scaled to 10 inches.
Before you upload, run through this list:
- Trim the canvas so there’s no extra white space or stray artboard around the design.
- Convert any text to outlines so fonts don’t shift or substitute on another computer.
- Check for leftover stray pixels near the edges of your shapes.
- Name your file clearly, like
logo-fullfront-black-300dpi.png, and note the shirt color and placement in your upload comments.
A guide on file formats for t-shirt printing breaks down exactly when PNG beats vector for your specific design.
DTF and dark-shirt pitfalls: transparency vs. white underbase and avoiding halos

DTF printing reads your file literally. Transparent pixels mean no ink gets laid down, and white pixels tell the printer to lay white ink. If your background is white instead of transparent, it won’t disappear on a dark shirt. It’ll print as a visible white rectangle around your logo.
The trickier problem is semi-transparency. Edges that are partially see-through often cause a faint white halo because the printer’s software builds a white underbase from anything that isn’t fully transparent. This shows up most on soft or anti-aliased edges around text and curves.
- Zoom into your file at 400% and check every edge for gray, fuzzy pixels instead of a clean cutoff.
- Preview your logo against a black background in your design software before exporting.
- Skip adding your own white layer. The printer’s system builds the underbase automatically from clean transparency.
Pro Tip: Drop a solid black square behind your logo layer temporarily. Any washed-out or ghostly edges will jump out immediately.
How printing method changes your artwork: screen print, DTG, DTF, embroidery, and vinyl
The printing method you choose changes what your file needs to look like. Sending the same PNG to every printer is one of the most common causes of delays.
- Screen printing needs color separations and Pantone references for each ink color, plus a slight choke around the underbase to stop white from peeking out at the edges, a step screen printers rely on for clean registration.
- DTG and DTF both want RGB PNGs sized to the final print dimension, but DTF is stricter about transparency since any leftover semi-transparent pixel can cause a halo.
- Embroidery needs simplified artwork with fonts and fine lines converted to vector outlines. Tiny text and gradients don’t translate well once a machine starts stitching.
- Vinyl and heat transfer work best with single-color vector shapes. Fine gradients and photo-realistic detail don’t cut cleanly, so plan for solid colors and simple stroke widths.
If you’re not sure which method fits your design, this checklist for choosing between screen print and heat press walks through the tradeoffs by design complexity and order size. Our own comparison of DTF versus sublimation covers why transparency and white ink behave differently depending on the method.
Exact pixel targets and placement sizes
Different placements call for different file sizes, and printing at the wrong resolution is one of the fastest ways to end up with a blurry shirt.
A DPI and pixel size guide has the full breakdown for sizes in between these.
If you need your logo on multiple placements, save a separate file for each size rather than shrinking one large file down. Before you finalize anything, drop your design onto both a dark and a light shirt mockup so you can see how the colors and edges hold up, and always request a proof from your printer so placement and scale match what you expect.
Final pre-upload checks, tech-pack essentials, and what to tell your printer
Before you hit upload, run through this list one more time:
- Spell-check every word in your logo, including small tagline text.
- Confirm fonts are outlined and layers are flattened or organized the way your printer asks for.
- Check your file size is under your printer’s upload limit.
- Note the job name, shirt brand, shirt color, placement, and finished print size in your order comments.
- List Pantone codes if brand color accuracy matters.
A short, consistent tech pack reduces mistakes and speeds up production, even for a single small order. Ask for a digital proof before printing, and check your printer’s washability guidance so you know what to expect after the first few washes.
Shay’s Print Shop upload specs and downloadable templates
We built our logo upload guidelines around the same preflight steps covered here: transparent PNGs or vector files, 300 DPI at print size, and clean edges with no stray pixels.
A DPI resource helps customers hit exact pixel targets without guessing, since a file that’s 72 DPI on screen can still print sharp at 300 DPI once it’s sized correctly for the shirt. If you’re placing a bulk order, upload your file early and flag your placement and shirt color in the order notes. That single step is what keeps your run moving without a delay while we confirm details back and forth.
Legal considerations for using a logo on apparel
If you’re printing a logo you didn’t design yourself, check that you actually have the rights to use it. A logo pulled from a search engine, a stock icon site, or another brand’s page can carry copyright protection even if there’s no watermark on it. Using it without permission can create legal exposure for you and, in some cases, for the printer producing the shirt.
If the logo includes another company’s name, symbol, or trademarked mark, get written permission before printing it on merchandise for sale or wide distribution. This matters even more for sports team logos, university crests, and well-known brand marks, which are frequently protected regardless of how the image was found.
If you’re building a logo for your own small business, a quick trademark search in your country’s registry can save you from adopting a mark that’s already claimed by someone else. Selling shirts with someone else’s registered trademark, even unintentionally, can lead to takedown requests or legal claims. If you’re printing shirts for personal use, like a family reunion or a team event, the risk is much lower but it’s still worth confirming you’re not reproducing licensed art without permission.
When to DIY vs. when to ask for help
A simple, flat logo with one or two colors and a single placement is easy to prepare yourself with the checklist above. If your design has fine gradients, tiny text under half an inch, several spot colors, or you need it sized for five different placements, that’s when working with a designer or your printer’s prepress team saves you time.
Watch for these red flags: text you can barely read at full size, inconsistent file versions floating around your inbox, or artwork that only exists as a screenshot. Help is available to clean up rough files and confirm your design print-ready before order production.

Ready to print? Here’s your next step
Once your file passes the checks above, you’re ready to order. It is possible to turn a finished logo into shirts, including packages such as 10 custom shirts for $99 on soft, durable 100% cotton.
To place your order, have these ready:
- A transparent PNG or vector file sized for your placement.
- Your shirt color and preferred placement (left chest, full front, or back).
- Any Pantone codes if brand color matching matters to you.
If your logo needs vectorizing, has multiple placements, or just needs a second set of eyes, help can be obtained to get it print-ready before it goes into production. Browse full custom t-shirt options to get started, or explore custom tumblers and vinyl stickers and mugs if outfitting an event with more than shirts.

FAQ
What is the golden rule for logo design?
A good logo should be simple enough to recognize at a small size and still work in a single color. For t-shirt printing specifically, that same simplicity keeps your file easy to prepare across every printing method, from embroidery to DTF.
What’s the best way to put a logo on a shirt?
For most small orders, direct-to-film (DTF) printing gives strong detail and color on cotton without needing separate screens for each color. Send a transparent PNG at 300 DPI sized to your placement, and confirm your shirt color so the printer can check your design against a dark or light background before printing.
What are the basic steps to design a logo?
Common approaches include researching your audience, sketching concepts, narrowing to one direction, refining it digitally, and testing it at different sizes and on different backgrounds. For apparel specifically, add a final step: exporting a transparent, vector, or high-resolution version made specifically for printing.
Can I create my own logo for free?
Yes, free tools like Canva let you design a logo, though transparent background exports typically require a paid Canva Pro plan. Whatever tool you use, export your final design as a PNG with transparency or as a vector file so it’s ready for printing.
Do I need a different file for embroidery versus printing?
Yes, embroidery generally needs a simplified, vector-based version of your logo since fine detail and small text don’t translate well into stitches. A printed version, on the other hand, can hold more detail as long as it’s exported as a transparent PNG or vector file at the right resolution.
