  • Patent number: 3990364
    Abstract: The invention provides for a screen printing method for printing on ceramic articles, wherein color in the form of an image to be printed is transferred via intermediate carriers on to the article to be imprinted wherein the improvement resides in that four intermediate carriers are each provided simultaneously with a color extract to produce a four-color print from a plurality of circulating intermediate carriers, and these color extracts are then transferred to four of a plurality of circulating articles, the cycle of the articles being staggered in relation to that of the intermediate carriers so that each intermediate carrier with a different color extract is brought up to each article in succession. The invention has particular application to a four-color print.
