The dye receiving sheet for preparation of a transparency according to the present invention is a sheet to be used in combination with a heat transfer sheet having a dye layer formed thereon and includes (2) a transparent substrate, (3) a transparent receiving layer provided on the transparent substrate for receiving the dye migrating from the heat transfer sheet corresponding to the energy applied from a thermal head and (5) an optically detectable layer provided on at least a part of the heat transferable sheet. By the provision of the optically detectable layer (5), improvement of running performance, operability within a heat-sensitive device as well as image density and sensitivity during printing can be attained, and also a detection mark can be freely added, whereby operability of the dye receiving sheet can be further improved.

Dye receiving sheet for preparation of a transparency

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.
