How to Prepare Your Artwork for DTF Printing: A Complete Guide

Why Artwork Preparation Matters for DTF

DTF (Direct to Film) printing produces incredibly detailed, full-colour transfers - but the quality of your final print is only as good as the artwork you supply. Getting your file format, resolution, and colour settings right before you order means sharper edges, more accurate colours, and a better finish on your garment.

The Best File Formats for DTF Printing

PNG (Recommended)

PNG is our preferred format for DTF transfers. It supports transparent backgrounds, which is essential. Without a transparent background, any white or coloured areas around your design will print as part of the transfer. Always save your PNG with a transparent background unless the white is intentional.

PDF, AI, EPS, and SVG

These vector and print-ready formats are also accepted and often produce very sharp results, particularly for logos and text-heavy designs. They are ideal if your design was created in Adobe Illustrator, CorelDRAW, or a similar programme.

JPG

JPG files are accepted but not recommended for designs with fine edges or text, as JPG compression can introduce artefacts around sharp lines. JPG also does not support transparency.

Resolution: How Sharp Does Your File Need to Be?

We recommend a minimum of 300 DPI (dots per inch) at the intended print size. This ensures your design looks crisp and detailed rather than pixelated or blurry.

A common mistake is designing at screen resolution (72 or 96 DPI) and then scaling up - this results in a blurry, low-quality print. Always work at 300 DPI from the start, or use vector formats that scale without quality loss.

Colour Mode: RGB vs CMYK

Design your artwork in RGB colour mode. Our DTF printers use RGB-based inks, so RGB files produce the most accurate colour reproduction. If you submit a CMYK file, the colours may shift slightly during conversion. Avoid Pantone or spot colours unless you can convert them to accurate RGB equivalents.

Transparency and Backgrounds

One of the most common mistakes we see is designs submitted with a white background when the intention was a transparent one. Always check your file before uploading:

  • Zoom into the edges of your design - you should see a chequerboard pattern, not a white box
  • In Photoshop, use the Magic Wand or Select and Color Range to remove the background
  • In Illustrator, simply delete any background rectangle that exists

Sizing Your Artwork

Size your design at actual print size at 300 DPI before uploading. Common sizes at DTF Print Online are A4, A3, 50x58cm, and 100x58cm.

If you are building a gang sheet, our gang sheet builder lets you resize and reposition designs after upload - but starting at the correct size gives you the most control.

Text and Fine Detail Tips

  • Keep text at 8pt or larger for clean, readable results
  • Very fine lines below 0.5mm may not transfer cleanly - thicken them slightly if possible
  • Avoid very light colours on white garments without strong contrast
  • Consider adding a thin outline to text or logos on complex backgrounds

Do Not Mirror Your Artwork

Unlike some other transfer methods, DTF transfers do not need to be mirrored before printing. Submit your artwork as it should appear on the finished garment - our printing process handles orientation automatically.

Quick Artwork Checklist
