Printing technology - Crisp, sharp texts and images

Printing technology - crisp, sharp texts and images

Whether in the letterpress-, offset-, gravure-, flexo-, or porous printing, the skill to transfer colors and letters onto pressure carriers, has been going on for a long time. When it comes to transferring characters, colors and pictures at extraordinary sizes as well as print media still pin sharp, just a few companies can meet these requirements. Therefore famous manufacturers of the print industry bet on our powerful optics, which search their own regarding dimension and precision.
