<p>A magnetic printing master prepared by: 1. coating a layer on a flexible support sheet; 2. prestructuring the coating in a periodic manner, and 3. laminating the CrO2-coated sheet onto a second adhesive-coated, support sheet, such as 3-7 mil polyester. The resulting film may be imaged by selective demagnetization and toned. Known transfer technology may then be used to provide a printing plate.</p> |
