    Abstract: An improved latently composable printing member and methods of preparing and composing the same. A heat sensitive polymer dispersion coating on a dimensionally stable base is placed in thermal contact with infrared absorbing indicia. Selective heating of the coating through the application of near infrared radiation to the absorbing indicia causes the polymer dispersion coating to form an insoluble solid solution in a pattern corresponding to the indicia on the master. The portions of the coating which do not form a solid solution are washed off the base with a solvent to form a relief printing plate.

    Abstract: A method for quickly making an intaglio or gravure printing plate through the use of near infrared irradiation. A pattern of protuberances or grooves is formed on a surface of near infrared transparent, moldable plastic, glass, or quartz which is not deformable at the temperature used in practicing the invention. This gravure matrix can be in the form of a sheet, endless belt, or plate. The information to be reproduced can be printed, written, or drawn in highly near infrared absorbing material on a copy sheet, which can be of paper, for example, or other substantially infrared transparent or reflective material. The copy sheet is assembled with the infrared absorbing material in contact with a base plate sheet of transparent, unoriented, near infrared non-absorbing plastic, which in turn is placed on the gravure matrix. Under uniform pressure of 5 to 50 p.s.i. the assembly is exposed briefly to near infrared energy. The base plate sheet will have formed therein an exact reproduction of the copy material in the form of a multiplicity of cells or grooves. This gravure printing plate can then be mounted according to known procedures on an offset gravure printing device.

    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.
