Abstract
The present invention relates to a method and apparatus for preparing varying degrees of gloss on printed matter in printing machines producing printed images on printed matter by application of an ink layer. An object of the present invention is to provide a method for producing varying degrees of gloss on printed matter with only one coating tower which comprises only one coating unit and no especially manufactured coating plate. The method according to the present invention comprises applying an ink layer from at least two ink systems on a substrate to be printed to produce a printed image. The printed image is subsequently coated with a coating, whereby each ink system changes degree of gloss in reaction with the coating layer.
