Patent number: 6183936Abstract: A method of preparing a lithographic printing plate which involves providing a plate precursor comprising a grained and anodized aluminium substrate coated with a metallic silver layer, imagewise exposing the precursor by means of a high intensity laser beam, and treating the plate by chemical and mechanical means in order to remove stains on the plate surface. On exposure of the plate precursor, removal of the metallic silver layer occurs in the exposed areas. The method provides press ready plates free of background stain, which give a clean, even appearance in exposed areas and show high image resolution and excellent durability on press, while eliminating the requirement for the use of intermediate film and developer chemistry.Type: GrantFiled: February 7, 2000Date of Patent: February 6, 2001Assignee: Agfa-Gevaert, N.V.Inventor: Philip John Watkiss

Patent number: 6177217Abstract: A method for positioning an array with periodic structures, for forming an image thereon, comprises the following steps: (i) producing a light beam along fast-scan axis; (ii) translating the array in a direction substantially perpendicular to the fast-scan axis; (iii) detecting the light beam alternatively by a pair of detectors, the detectors being located near opposite edges of the array along the fast-scan axis; (iv) providing substantially periodic signals by the pair of detectors in accordance with their detection of the light beam; (v) determining relative phases of the periodic signals, the relative phases corresponding to misalignment of the array; (vi) sensing phases of the periodic signals and rotating the array such that the long axes of the periodic structures are substantially parallel to the fast-scan axis.Type: GrantFiled: July 23, 1999Date of Patent: January 23, 2001Assignee: Eastman Kodak CompanyInventors: John A. Agostinelli, Lee W. Tutt
