Orrset colour printing machine drying each layer separately - has ultraviolet dryers ensuring uniform colour intensity, sharpness and brightness

摘要

In an offset printing process, the separate sheets or the continuous lengths of the carrier are printed in a number of colours one after the other. After each colour printing the carrier is dried using ultraviolet radiation. When wrappings, catalogues, etc. are printed in a number of colours one after the other and dried after the final colour has been printed there is a loss of colour intensity and brightness. By drying each colourseparately, layers of colour of the same thickness can be used, with corresponding economines, and a quality of colour not previously possible is obtd. on the cheapset paper.
