A collect-printing unit for the indirect security printing in dry-offset of a complete multi-color ink coating for use in printing on supports such as sheets and webs in a rotary printing press, said collect-printing unit comprising:

• a plate cylinder having at least one letterpress printing plate affixed to the periphery of said plate cylinder;
• a first blanket cylinder contacting said plate cylinder;
• a second blanket cylinder contacting said plate cylinder and having a plurality of ink receiving blankets affixed to the periphery of said second blanket cylinder;
• a plurality of sectorially cut-out rollers, each of said cut-out rollers having at least one hard cut-out ink contour plate affixed thereto, each of said ink contour plates, receiving one color of said multi-color ink coating, each of said cut-out rollers further having an inking unit coordinated thereto to supply said one color of said multi-color ink coating to said at least one ink contour plate affixed thereto, each of said plurality of cut-out rollers being in contact with each of said ink receiving blankets on said second blanket cylinder to impart said complete multi-color ink coating to each of said ink receiving blankets on said second blanket cylinder;
• a first ink transfer cylinder contacting said plate cylinder, and a second ink transfer cylinder contacting both said first ink transfer cylinder and said second blanket cylinder, said plate cylinder receiving a double inking formed as a combination of partial ones of said complete multi-color ink coatings that are imparted to successive ones of said ink receiving blankets on said second blanket cylinder, said partial coatings being transferred in registry to said plate cylinder from both said first ink transfer cylinder and said second blanket cylinder, said plate cylinder transferring said complete multi-color ink coating to said first blanket cylinder;
• and
• a counter-pressure cylinder cooperating with said first blanket cylinder so that the support to be printed is printed by being interposed between said first blanket cylinder and said counter-pressure cylinder.
