🖨️ Preparing Files for DTF Printing – Practical Tips for a Perfect Result

DTF printing allows for quick and high-quality customization of graphics on textiles. To ensure a superb final result, it is crucial to properly prepare the file for printing.

In this guide, you will learn:

which formats are most suitable,
how to set up the color space,
what to watch out for with white color and backgrounds,
and how to safely send your file.

📁 Recommended File Formats

For successful DTF printing, we accept the following formats:

PDF – for vector graphics (e.g. logos, text)
PNG – for bitmap images (photos, illustrations)
→ size 1:1, resolution at least 300 dpi

The file must be finalized – we print exactly what we receive. If you need additional help or processing, you can order it separately.

🎨 Color Space – RGB or CMYK?

RGB: more vibrant, intense colors – most common choice
CMYK: more accurate color reproduction (e.g. for precise shades)

➡️ We recommend RGB, as most clients want the most vibrant colors possible. The difference between the two is usually minimal, but if you need a very precise shade, please let us know in advance.

🖼️ Resolution and Ratio

Use 300 dpi
Prepare the design at actual size (1:1)
For PNG formats, remove the background if it is not part of the design

⚪ Handling White Color

In DTF printing, white is applied as a separate layer – it is not “default”, but must be specifically included in the design.

Everything marked as white will be printed in white
Do not change white to another color
If you don’t want white, use a transparent background

🧽 Backgrounds and Transparencies

Remove backgrounds you don’t want on the final product
Do not use transparent layers – they are not interpreted correctly
If using images with gradients, test before printing

🧩 Combining Graphics on Sheets

For greater efficiency in ordering:

Arrange graphics on a printing sheet up to 56 cm wide
Leave at least 4 mm of straight margin between designs for easier cutting
You can prepare one design and indicate the number of repetitions in the filename (e.g. _logo_5x.png)

📌 This way, we optimize material usage and provide you with a better price calculation.

📤 Sending Files

Send your file:

via email to dtf@sitotisk.net (if the file is not too large)
or via WeTransfer.com – make sure to send an additional confirmation email

⚠️ If you do not receive a response within 24 hours, check your spam folder or contact us – sometimes links from WeTransfer end up in junk mail.

❗ Common Mistakes (and How to Avoid Them)

❌ Incorrect resolution (e.g., 72 dpi) → use 300 dpi
❌ Missing white ink → clearly indicate it in the design
❌ Transparent layers → remove them
❌ Images without a background → ensure the background is truly not included
❌ Unclear layout on the sheet → use even spacing

✅ Quick tips for preparation:

Maximum width: 56 cm
You can place designs vertically or horizontally
If you are unsure, ask us before submission – we are happy to help
Use programs: Illustrator, CorelDraw, Photoshop, Canva, Gimp, Inkscape, Photopea.com, etc.
