Abstract: Apparatus for a gravure-type printing process utilizing a composing member having a multicellular surface pattern, and a pick sheet coated on one side with a layer of polymer-containing, thermoplastic material. All of the cells of the composing sheet are initially filled with a solid material which is selectively removable from individual cells. The cell-fill material is specially formulated to exhibit a specific affinity for the thermoplastic coating on the pick sheet when the coating is activated through localized heating. Graphic representations that are infrared absorbent are recorded on the uncoated side of the pick sheet which is then exposed to infrared radiation while the coated side is held in close contact with the filled cellular surface of the composing member resulting in an adhesive attraction between the coating and the solid material in the cells beneath the indicia. Separation of the two elements removes the cell-fill material from only those cells which define imaged areas corresponding to the indicia to be reproduced. The empty cells are receptive to filling with an ink, while nonimaged areas of the sheet contain no printing cells, so that the composing member can then be used as a printing master. The pick sheet, carrying a discontinuous, raised image, comprising a multiplicity of uniformly distributed, discrete particles of solid material bonded to the thermoplastic coating, can be employed as a relief printing plate.
