![](https://storage.crisp.chat/users/helpdesk/website/-/7/7/9/5/7795d7eea232ec00/image_4gic1h.png)

For the best possible result, our system works exclusively with **PNG files**.
This ensures that your design is processed quickly, sharply, and with accurate colors.


**Key Requirements**
* **File format: PNG only**
Our systems are fully automated and only recognize PNG files. File types such as PDF cannot be processed.
* **Color profile: Always RGB**
Save your file in RGB. Our machines are optimized for this color mode. If you use CMYK, colors may appear differently in the final product.
* **Preserves quality**
PNG files retain all details and support transparency without any loss of quality. This ensures your design remains sharp and clean, even when printed.


**In Short**
Use a **PNG file in RGB** to ensure the fastest processing and the best possible print result.
