The #1 cause of delays in custom t-shirt orders? Artwork that isn't print-ready. Low-resolution images, wrong file formats, and missing transparent backgrounds force back-and-forth that adds days to your timeline.
This guide walks you through everything you need to prepare professional, print-ready artwork—whether you're a designer or just need to get your logo on some shirts. Plus, we'll show you how T-Shirt Elephant's design studio can help, and what to do if you need a hand with your files.
File Formats Explained
Not all image files are created equal. The format you submit can make the difference between crisp, clean prints and blurry, pixelated disappointment.
Vector Files (Best Choice)
Vector graphics use mathematical paths instead of pixels. This means they can be scaled to any size—from a business card to a billboard—without losing quality. If you have vector files, always use them.
AI, EPS, PDF, SVG Best
Infinitely scalable, perfect for logos and text. The gold standard for t-shirt printing.
Raster Files (Good with Conditions)
Raster images are made of pixels. They can work great for printing, but only if they're high enough resolution and in the right format.
PNG Recommended
Supports transparent backgrounds. Use 300 DPI minimum. Best raster option for t-shirts.
TIFF Good
High-quality, uncompressed. Large file sizes but excellent print quality.
JPEG Avoid
Compressed = quality loss. No transparent backgrounds. White box prints on colored shirts.
GIF Avoid
Limited to 256 colors. Low quality for printing. Use PNG instead.
Not Sure What Format You Have?
Check the file extension (.ai, .eps, .png, etc.). If you received your logo from a designer, ask them for the vector files—they should have provided AI or EPS versions. No vector? A high-res PNG works too.
Resolution Requirements (DPI)
DPI (dots per inch) determines how sharp your print will be. Higher DPI = more detail = cleaner prints.
The 300 DPI Rule
Your artwork should be 300 DPI at the actual print size. This is the industry standard for professional printing.
| Print Size | Required Pixels (at 300 DPI) | Common Use |
|---|---|---|
| 3" x 3" (left chest) | 900 x 900 pixels | Logo placement |
| 10" x 12" (standard front) | 3000 x 3600 pixels | Front/back prints |
| 12" x 16" (full front) | 3600 x 4800 pixels | Large designs |
How to Check Your File's DPI
- Windows: Right-click file → Properties → Details → look for "Horizontal/Vertical Resolution"
- Mac: Open in Preview → Tools → Show Inspector → look for "DPI"
- Photoshop: Image → Image Size → check "Resolution"
A Common Mistake
A "high-resolution" photo from your phone (4000 x 3000 pixels) may only be 72 DPI—fine for screens, but blurry when printed. Check both pixel dimensions AND DPI. You need 300 DPI at the final print size.
Choosing Colors That Work
The colors in your design interact with the shirt color. Get this wrong, and your design disappears or looks muddy.
The Golden Rule: Contrast
Light ink on dark shirts. Dark ink on light shirts. Contrast makes your design pop.
White on Black
Classic, high-contrast, always works
Black on White
Clean, professional, versatile
Yellow on Navy
High visibility, great for teams
White on Maroon
Elegant, great for thin lines
Dark Blue on Navy
Not enough contrast—avoid
White on Light Yellow
Design disappears—avoid
Colors for Dark Shirts
Use: White, yellow, light blue, pink, orange, bright green, metallic/foil
Avoid: Black, navy, dark green, brown, dark purple
Colors for Light Shirts
Use: Black, navy, dark green, maroon, brown, dark purple
Avoid: White, pale yellow, light pink (unless intentionally subtle)
RGB vs CMYK vs Pantone
- RGB: For screens (computers, phones). Not for printing.
- CMYK: For digital printing. Colors may shift slightly from screen.
- Pantone (PMS): Industry standard for exact color matching. Use for brand colors.
Pro Tip: Specify Pantone Colors
For exact brand color matching, add Pantone codes to the notes section of your order. Example: "Logo blue should be Pantone 286 C." Use Solid Coated (C) codes for best results with textile inks.

Creating Artwork with Canva
Canva is a great free option for creating t-shirt designs, especially if you're not a professional designer. Here's how to export files that work for printing.
-
Create Your Design
Start with a custom size canvas. For a full front print, use 12" x 16" (or 3600 x 4800 pixels).
-
Click Share → Download
In the top right corner, click the Share button, then select Download.
-
Select PNG Format
Choose PNG as your file type. This preserves quality and allows transparency.
-
Check "Transparent Background"
Enable the transparent background option. Note: This requires Canva Pro.
-
Convert to 300 DPI (Important!)
Canva exports at 96 DPI by default. Use a free converter like Clideo to convert your PNG to 300 DPI, or create your canvas at 3x the final size.
-
Upload to Design Studio
Upload your finished PNG to the T-Shirt Elephant design studio to preview on your chosen shirt.
Canva's DPI Limitation
Canva exports at 96 DPI, but printing requires 300 DPI. Workaround: Create your canvas at 3x the final print size (e.g., 36" x 48" for a 12" x 16" print), or use a free DPI converter after downloading.

Common Mistakes That Delay Orders
Avoid these pitfalls to keep your order on schedule:
Low-Resolution Images
Files under 300 DPI at print size result in blurry, pixelated prints. Always check resolution before submitting.
White Background Not Removed
A white background prints as a white box on colored shirts. Export as PNG with transparent background.
Wrong File Format
Word documents, PowerPoint files, and low-res JPEGs cause delays. Use AI, EPS, PDF, or high-res PNG.
Text Too Small or Thin
Fine text and thin lines can disappear when printed, especially on textured fabrics. Keep text readable at print size.
Too Many Colors (Screen Printing)
Each color in screen printing requires a separate screen. More colors = higher cost and longer production.
Dark Design on Dark Shirt
Navy ink on a black shirt won't be visible. Always ensure strong contrast between ink and fabric.
Not Reviewing the Proof
Skipping proof review means missing typos, color issues, or placement problems until it's too late.
Missing Fonts in Vector Files
If fonts aren't converted to outlines, they may substitute incorrectly. Always outline/flatten text before sending.
Frequently Asked Questions
What file format is best for custom t-shirt printing?
Vector files (AI, EPS, PDF, SVG) are best because they scale infinitely without losing quality. If you don't have vector, use PNG with transparent background at 300 DPI. Avoid JPEGs when possible.
What DPI should my t-shirt artwork be?
300 DPI at the actual print size. A 12" wide print needs to be 3600 pixels wide (12 × 300). Lower resolution results in blurry prints.
How do I remove the background from my image?
Use T-Shirt Elephant's built-in background removal tool in the design studio, or free tools like remove.bg. In Canva Pro, use the background remover and export as PNG with transparent background.
Can I use a JPEG for t-shirt printing?
JPEGs can work but aren't ideal—they compress quality and don't support transparency. White backgrounds will print as white boxes on colored shirts. Convert to PNG with transparent background for best results.
Why does my printed design look different than on screen?
Screens use RGB (backlit colors) while printing uses CMYK or Pantone inks. Bright screen colors often appear slightly muted when printed. For exact matching, provide Pantone color codes.
What's the difference between vector and raster?
Vector uses mathematical paths (infinitely scalable, perfect for logos). Raster uses pixels (can become blurry when enlarged). Vector is always preferred when available.
How do I specify a Pantone color for my order?
Add Pantone codes to the notes section when ordering, or email [email protected]. Use Solid Coated codes (ending in C) for best results. Example: "Logo should be Pantone 286 C."
Can you help fix my artwork?
Yes! Email your artwork to [email protected] and we'll help vectorize logos, remove backgrounds, fix resolution, and adjust colors. Basic cleanup is often included with orders.
What size should my design file be?
Standard print areas: 3-4" for left chest logos, 10-12" wide for front/back prints, up to 12x16" for full front designs. Create files at actual print size at 300 DPI.
How do I export from Canva for t-shirt printing?
Click Share → Download → PNG → check "Transparent background" (Canva Pro). Canva exports at 96 DPI, so use a DPI converter or create your canvas at 3x final size to compensate.
What colors work best on dark shirts?
Light and bright colors: white, yellow, light blue, pink, orange, bright green. Avoid dark colors like navy or brown—they won't be visible against dark fabric.
Do I need a transparent background?
Yes, for most designs. Without it, you'll get a visible box around your design (white backgrounds print as white on colored shirts). Save as PNG to preserve transparency.
