PRINTING TOOL FOR PRODUCTION OF SYNTHETIC IMAGE DEVICES AND A METHOD OF MANUFACTURING SUCH A TOOL

摘要

A method for manufacturing of a tool for production of synthetic image devices comprises cutting (210) a surface structured plate, giving a respective first and second edge. The plate has geometrical structures - microimages or focusing elements - in a first surface. Cells comprising the geometrical structures have a predetermined period in a first direction. The first edge is brought (212) to face the second edge in a close proximity. The first direction of a first area of the plate adjacent to the first edge is positioned with a predetermined angle with respect to the first direction of a second area of the plate adjacent to the second edge. A relative translation in said same plane between the first edge and the second edge is adapted (214) for bringing a first cell border in the first area to a predetermined distance, relative a corresponding second cell border in the second area. The first and second edges are mutually fixated (216) and mounted (218) onto a cylindrical support. A tool for manufacturing of synthetic image devices is also disclosed.
