All formats can be realized in both offset and digital printing. You can choose the ideal method which depends on the volume, degree of personalization and urgency of printing.
Offset printing is usually used for larger print runs (ca. 10,000) and is a bit cheaper for higher volumes. For personalized elements, the standard and premium versions are available for offset printing. The former allows the personalization of the address, the coupon code and the address by inkjet. With premium laser personalization, you can create rich elements such as personalize the body text (black only) or print barcodes.
Digital print requires less time in the implementation and allows a more comprehensive personalization - even 1:1 image personalization. However, it´s often more advisable for smaller volumes (up to around 10.000 mailings) because of the higher cost.
