Abstract: The invention relates to a paper coloring apparatus for especially water colors or water-based inks, wherein a driven running paper web is positioned around a turning roller constituting the counter-pressure roller for an inker and, together with the latter, are included in a roller train adapted to convey ink from a reservoir to the inker. The last roller in the roller train is at least partially immersed in the ink reservoir and is independently rotatable for conveying ink to the next adjacent roller in the roller train. According to the invention, the rest of the roller train is adapted to be driven by the running paper web.

Abstract: The invention relates to a paper coloring apparatus for especially water colors or water-based inks, wherein a driven running paper web is positioned around a turning roller constituting the counter pressure roller for an inker and, together with the latter, are included in a roller train adapted to convey ink from a reservoir to the inker. One has aimed at transferring ink to the paper in so small amounts that after-drying of the paper becomes unnecessary. According to the invention, the roller train is adapted to be driven by means of the running paper web and comprises five or more rollers.
