Class Information
Number: 101/453
Name: Printing > Planographic > Lithographic printing plates
Description: Articles or devices for printing characterized by having a surface which has a first area of configuration or printing to be reproduced, which first area receives ink to be transferred to other materials, and second areas on said surface which are not to be reproduced, which second areas are not receptive to ink thus failing to transfer ink therefrom to said other material.
