Vector graphics are mandatory for my product. What does this mean exactly? 

We use offset or digital printing technology to produce most products such as flyers, brochures and the like. Here, we can basically process any format.

For promotional items, in contrast, we use different print techniques such as laser engraving, pad or screen printing. The artwork file for these products must contain vector data only.

Pixel-based files such as JPEG, GIF, PNG and TIF cannot be processed with such products.

To learn how to convert pixel data to vectors and what to pay attention to is described in a separate article under "Vectordata".
