Abstract
Processing of lithographic printing plates, particularly a method of preventing bending of the plates during processing. Conventionally, the chemical processing of lithographic printing plates includes advancing the plates between pairs of rotating brushes. The trailing edge of such plates is bent upwardly or downwardly after passing through the pairs of brushes. The present method places the pairs of brushes at an oblique angle with respect to the axis of advancing such that the leading and trailing edges of the lithographic plate laterally incrementally contact the brushes. As a result, bending is eliminated.
