In a method of producing an image of a coloured design for preview purposes, a substrate is selected and a pad layer (2) is printed on the substrate (3). A series of known tonal values (1) are printed on the pad layer (2) and colour information read from the image produced by means of a spectrophotometer. The data obtained is then manipulated in a computer in order to generate a digital preview of the appearance of the image. Alternatively, where the substrate is transparent, the known tonal values may be printed on the substrate and the pad layer printed on top of the tonal values or the known tonal values printed on the substrate and a backing layer laminated with the substrate. The method enables the appearance of an image to be accurately predicted. |
