How to Set Up DTF Artwork in Canva Without Blurry, Blocky Prints

1. The golden rules for Canva + DTF

Before we dive into click-by-click, here are the rules I keep repeating in the workshop:

• Size the canvas to the final print size in cm/mm – don’t design on a random Instagram post template.
• Use 300 DPI when you create the design (or the “High quality” PDF/PNG export setting if you don’t see DPI options).
• Don’t stretch tiny images – if it’s low-res going in, it’ll be low-res on the garment.
• Export as PNG with a transparent background for most DTF work.
• Keep fonts and strokes bold enough to print cleanly – no hairline scripts at 4pt.

• Set size first
• 300 DPI / high quality
• Transparent PNG
• No tiny screenshots

2. Set your canvas to the actual print size in Canva

The biggest mistake is designing on a generic “A4 document” or “Instagram post” and then expecting it to magically fit a chest print.

2.1 Decide your print size first

As a rough guide (same numbers we use at Brandum):

• Left-chest logo: 8–10 cm wide
• Standard front / back print: 26–32 cm tall
• Sleeve print: 5–7 cm wide

2.2 Create a correctly sized Canva document

In Canva:

1. Click “Create a design” → “Custom size”.
2. Switch the units to cm or mm.
3. Enter your final print size (for example, 28 cm wide × 32 cm high for a front print).
4. Click Create.

This means what you see on screen is basically what will end up on the film at full size.

3. Keep your artwork clean: no stretched screenshots

Canva makes it very easy to drag random images into a design. That’s also how a lot of DTF jobs get ruined.

3.1 What not to do

• Dragging in a tiny logo you screenshotted off Instagram.
• Using a 400×400 pixel web image and blowing it up to 28 cm wide.
• Building a design out of lots of low-res PNGs someone emailed years ago.

3.2 What to do instead

• Start from the original high-res artwork wherever possible.
• Ask your designer for PNG (300 DPI, transparent) or vector (PDF/SVG) files.
• If you absolutely have to use an existing image, keep it small on the design – don’t scale it beyond 100–150% of its original size.
• Use Canva’s own vector-style elements and bold fonts where you can – they scale better.

4. Colour setup: keeping Canva & DTF friends

Canva works in RGB by default, which is fine for DTF as long as you don’t keep bouncing files between different colour spaces.

4.1 Simple colour best practice

• Design in Canva normally – that’s already RGB.
• Use solid colours and simple gradients – avoid super-soft glows that fade into nothing.
• If you have brand colours, use their hex codes consistently.
• Don’t convert Canva exports to CMYK and back again in other tools – keep it clean.

5. Exporting from Canva for DTF (step by step)

Once the design looks good, this is how I want you to export it for us or any decent DTF supplier.

5.1 PNG export for most DTF jobs

1. Click “Share” in the top right.
2. Click “Download”.
3. Set File type = PNG.
4. Tick “Transparent background” if it’s not already (this is crucial – you don’t want a random white box around your logo).
5. Set Quality/Size to the maximum / 300 DPI equivalent if Canva shows that slider.
6. Choose the correct page if your file has multiple pages.
7. Click Download.

5.2 When to use PDF

If your design is mostly text and Canva shapes with no imported photos, you can also export as:

• File type = PDF (Print)
• Select “High quality” / “Flatten PDF” off if you’re sending to a printer who prefers vector PDFs.

For most people using Canva, a high-quality PNG with transparent background is the safest bet.

6. Common Canva → DTF problems and how to fix them

6.1 “The print looks blurry / pixelated”

Likely cause: tiny artwork scaled up, or canvas smaller than the print size.

Fix:

• Rebuild the design on a canvas set to the correct print size.
• Replace low-res images with higher resolution originals.
• Keep small details genuinely small on the garment, not blown up from tiny sources.

6.2 “There’s a random white box around my design”

Likely cause: exported with a solid background instead of transparent.

Fix:

• Remove any background colour layer in Canva (set it to transparent or delete it).
• Re-export as PNG with ‘Transparent background’ ticked.

6.3 “My text looks too thin / bits have disappeared”

Likely cause: very thin fonts or tiny sizes that don’t translate well to print.

Fix:

• Use bolder fonts and avoid extra-light weights for small text.
• Make sure important text is at least around 6 pt equivalent at print size.
• Simplify decorative text for print – what looks pretty on screen can fall apart on fabric.
