Abstract
There are disclosed a method of delivering pictorial image data per each color obtained by applying color resolution to a manuscript using a color scanner to a sublimation transfer printer to effect a transfer from a sublimation transfer sheet to an image-receiving sheet, thus to make a hard copy of a color image, and a device for implementing such a method. 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.
