The image data comprises three primary data of cyan, magenta and yellow and black data calculated from the three primary data. Data obtained by applying color and gradation corrections to the four color data are delivered to the sublimation transfer printer. The sublimation transfer sheet is provided with a transfer ink layer of four colors of cyan, magenta, yellow and black. By the operation of the sublimation transfer printer, the ink of each transfer ink layer is transferred onto the image-receiving paper, thus to make a hard copy.

Abstract: This invention relates to a technique for inspecting picture patterns on prints which are being run in a rotary press or the like, and more particularly to a method in which reference data read out of a reference print is written in a memory, and inspection data read out of a print under inspection is compared with the reference data for every picture element for instance to determine whether or not the print is acceptable, and an apparatus for practicing the method. The specific feature of the invention resides in that (1) in reading the above-described data a print running speed or the position of a picture pattern in the direction of width is detected to rewrite the reference data, (2) in data comparison, the comparison level is optionally set up, and (3) the data comparison is carried out not only for every picture element, but also for the sum of picture elements over the entire picture pattern and for the sum of picture elements arranged linearly in the print running direction.

Abstract: An inspecting liquid is dropped onto a resist layer formed on a gravure printing plate and is allowed to permeate the resist layer or gelatin resist layer to reach the printing plate so that a short circuit is formed between the inspecting liquid and the printing plate. The time required for forming the short circuit in the resist layer is measured by utilizing an oscillator pulse counting circuit to determine the conditions of the resist layer thereby to improve the quality of the finished printing plate.
