Because no color information was preserved in the photographic process, the photographer would make detailed notes on the colors within the scene and use the notes to hand paint the negative before transferring the image through colored gels onto the printing plates.
Before final printing, the image is proof printed and any errors corrected. In the direct form of printing, the inked image is transferred under pressure onto a sheet of paper using a flat-bed press. The offset indirect method uses a rubber-covered cylinder that transfers the image from the printing surface to the paper. Colours may be ...
