Printing press and printing method of lenticular lens sheet

摘要

In a printing press (100) of a lenticular lens sheet (1), a cocking adjustment unit (140, 213-215) adjusts the relative angle between a plate (10) on which a pattern (13) formed from a plurality of pattern portions (A1, B1) is formed such that boundary lines (14) between the adjacent pattern portions become parallel and a transparent lenticular lens sheet (1) on which a plurality of lenses are formed such that groove lines (2) between the adjacent lenses become parallel. An adjustment amount calculation unit (231) calculates an adjustment amount for the cocking adjustment unit (140, 213-215) based on the relationship between the boundary lines (14) and the groove lines (2) in a state in which the lenticular lens sheet (1) is overlaid on the plate (10). A printing method of a lenticular lens sheet (1) is also disclosed.
