Abstract

1467665 Multi-colour proofing AMERICAN HOECHST CORP 8 March 1974 [9 March 1973] 10413/74 Heading G2C A method of multi-colour proofing comprises forming the image of a first colour on an opaque carrier and then successively superimposing the image of each other colour, in register, on the opaque carrier, the image of at least one of the other colours being superimposed on the opaque carrier by placing a transparent sheet having the image of that colour thereon on the opaque carrier (see Example 5). The transparent sheet may be formed by applying a light-sensitive coating of the appropriate colour to the sheet, exposing it through its respective colour separation and removing the colour in pre-selected areas on the sheet to produce the image. The image of at least one of the remaining colours may be superimposed on the opaque carrier by transferring a layer of that colour from a transfer sheet to the carrier and removing the transferred colour from pre-selected areas on the carrier to leave the image of the colour on the carrier. The first colour is preferably magenta. Examples 1-4 illustrate the preparation of imagebearing transparent sheets.
