Abstract
Disclosed is a metering device for the application of lacquer to printing plates 16, comprising a first doctor blade 1 which serves as a damming-up blade and a second doctor blade 2 acting as a metering blade. The two flexible blades are arranged parallel to one another and are inclined toward the surface of the printing plate. They define a lacquer bath 3 into which lacquer is metered via a spray tube 7 having outlet openings 19. The first doctor blade 1 can be adjusted in height, and adjustment is effected in such a way that the lower edge of the blade 1 is in sealing contact with the printing plate 16. The second doctor blade 2 is fastened to an adjusting means 6 and its height can be chosen independently of the position of the first doctor blade.
