Densitometry is the most applied measuring technique for color control in the printing industry, because of the well direct dependence between density and the thickness of the ink film. Especially the inline control at highest printing speeds and the measurement with every revolution of the whole color control bar offer new fields of process automation in offset printing. deCon as a state-of-the-art measuring system is offering all these features. As an innovator we constantly rise the ease of use and the usability of deCon. Therefore we offer traversed deCon systems as well as deCon systems for the whole web width.
