Usage of Wash on the plate is not recommend as the washes attack the image areas and make them non receptive of the printing ink. We call this as plate binding. The blanket wash is having certain solvents, which react with the plate image areas. To solve this problem I recommend that after the usage of blanket wash pls. wet-wash the blanket cylinder with a swab of sponge wet with water. This will completely remove the wash and so avoid plate cancellation.
