We talk a lot about security design as an important part of a secure document. As a basic rule, we emphasise that in secure design/printing basic CMYK colours and commercial screens/raster graphics should not be used, but at the same time more and more security products are being printed with digital printing technology.

In most cases, security design is connected to key security elements such as a guilloche, microtext and latent image. But these elements can only protect a product if they are designed and printed according to very strict rules.

If a security document printed with digital technology could risk looking like a forgery, the question is: should we even be using digital technology to print security designs?

Notwithstanding this question, digital printing is more and more used in the security printing industry not only for personalisation but also for printing the core design; therefore, we need to understand what is possible and what is not in order to produce quality security products.
