Both systems are based on conventional UV application but use highly reactive inks, which contain more and different photoinitiators compared to a full or conventional UV system. These photoinitiators cause the immediate drying process and lead to the big advantage of a dry sheet once it comes off the press. It’s also these photoinitiators which make the highly reactive inks more expensive, therefore both applications are most economically used for short runs and a high share of 4/4 or 5/5 jobs.
The dry sheets do not require protection coatings as we often see in conventional printing. The coating unit can now be used for special effects or the investment can simply be saved. As the inks are dry or cured much faster than conventional inks, they basically stay on the sheet surface, so depending on the substrate the colors look brighter and the whole printed image appears sharper.
