Abstract: A wiping apparatus for an intaglio printing machine has a first wiping roller which is in rolling contact with a plate cylinder and which is driven in the same rotational direction as that of the plate cylinder; a second wiping roller which is in rolling contact with the first wiping roller and which is frictionally driven in the same direction as that of the first wiping roller; an ink scraper member brought into tight contact with the outer surface of the second wiping roller; an ink tray disposed under the first and second wiping rollers; and wiping paper having substantially the same width as each of the first and second wiping rollers, brought into contact therewith, and driven at a low speed in a direction opposite to that of movement of the wiping paper contacting surfaces of the first and second wiping rollers.

Abstract: An intaglio printing machine includes a plate cylinder having a plate thereon, a pattern roller having projections which are in rolling contact with the outer surface of the plate, and an inking unit with a duct roller which is in rolling contact with the pattern roller, wherein the duct roller has substantially the same diameter as that of the pattern roller which includes the projections, and ink holding recesses having different depths corresponding to those of the plate are formed in the outer surface of the duct roller along the circumferential and axial directions thereof.

Abstract: An intaglio printing process utilizing a printing plate consisting of a precise engraving element which is adapted from a gravure printing plate. This printing plate is applied on the plate cylinder and printed with very stiff and viscous ink as used for engraving intaglio printing. Ink of various colors may be applied separately on different portions of the gravure plate surface by rollers. After inking, surplus ink can be wiped of by a wiping roller. Printing paper is introduced between the plate cylinder and impression cylinder for printing.
