Relief Printing

We produce printing plates specifically for flexography, flexo post-print and flexo pre-print, as types of relief printing. The high quality of the printing plates is particularly important in this sector.

All relief printing processes have one thing in common, which is that the printing elements of the image sit higher than the non-printing elements. The printing elements are covered with a layer of ink, after which the print image is transferred onto the print substrate. The relief printing technique is used in the following printing systems: letterpress, flexography and letterset.

  • Letterpress
  • Flexography
  • Letterset

We produce printing plates specifically for flexography, flexo post-print and pre-print, and letterpress, as categories of relief printing. High-quality printing plates are particularly important in this sector.

 

 

 

Letterpress

Letterpress is the oldest and best-known relief printing method. Johannes Gutenberg developed this process in around 1450: the different letters of his moveable lead type could be arranged freely. Gutenberg's invention represented the first opportunity to produce copies quickly and cheaply. For the first time, printing formes could be altered at will, and changed over quickly and economically. 

 

Application fields for letterpress: paper | tickets | labels | indirectly, cups too

Flexography

Another type of direct relief printing is flexography. Here, the printing forme is a flexible photopolymer plate. Low-viscosity inks are used in flexography, and are transferred directly onto the print substrate using a flexible plate. The thin, liquid ink is transferred to the raised plate using an anilox roller, which has engraved cells that are all the same size. The print image is then printed onto the substrate. We specialise in plate production for flexography. The application fields for flexography are primarily materials that will go on to cover packaging materials.

 

Application fields for flexography: labels | films and film composites | paper | corrugated board

Letterset

Letterset is the only indirect relief printing method. Here the print image is transferred onto the substrate via an intermediate carrier, a rubber blanket mounted on a cylinder. This process is chiefly used for printing labels, carrier bags and other bags, as well as job work and forms.
