the dye image could also be used such as using a heated platen use of pressure and heat external heating etc also as noted above in making a color proof a set of electrical signals is generated which is representative of the shape and color of an original image this can be done for example by scanning an original image filtering the image to separate it into the desired additive primary colors i e red blue and green and then converting the light energy into electrical energy the electrical signals are then modified by computer to form the color separation data which are used to form a halftone color proof instead of scanning an original object to obtain the electrical signals the signals may also be generated by computer this process is described more fully in graphic arts manual janet field ed arno press new york 1980 p 358ff the disclosure of which is hereby incorporated by reference the dye receiving element being in a superposed relationship with the dye donor element so that the dye layer of the donor element is in contact with the dye image receiving layer of the receiving element the above assemblage comprising these two elements may be preassembled as an integral unit when a monochrome image is to be obtained this may be done by temporarily adhering the two elements together at their margins after.
