Abstract
In a printing press of a lenticular lens sheet, a cocking adjustment unit adjusts the relative angle between a plate on which a pattern formed from a plurality of pattern portions is formed such that boundary lines between the adjacent pattern portions become parallel and a transparent lenticular lens sheet on which a plurality of lenses are formed such that groove lines between the adjacent lenses become parallel. An adjustment amount calculation unit calculates an adjustment amount for the cocking adjustment unit based on the relationship between the boundary lines and the groove lines in a state in which the lenticular lens sheet is overlaid on the plate. A printing method of a lenticular lens sheet is also disclosed.
Claims18
A printing press of a lenticular lens sheet, comprising:
- a cocking adjustment unit that adjusts a relative angle between a plate on which a pattern formed from a plurality of pattern portions is formed such that boundary lines between the adjacent pattern portions become parallel and the lenticular lens sheet on which a plurality of lenses are formed such that groove lines between the adjacent lenses become parallel and which is transparent;
- a table on which the plate and the lenticular lens sheet are placed;
- an adjustment amount calculation unit that calculates an adjustment amount for the cocking adjustment unit based on a relationship between the boundary lines of the pattern formed on the plate and the groove lines of the lenticular lens sheet that are in a state in which the lenticular lens sheet is overlaid on the plate placed on the table;
- and
- a plate cylinder to which the plate is attached,
- wherein the cocking adjustment unit comprises a plate cylinder cocking device that adjusts an axial-direction orientation of the plate cylinder based on the adjustment amount calculated by the adjustment amount calculation unit.
A printing method of a lenticular lens sheet, comprising the steps of:
- positioning a plate on which a pattern including a plurality of pattern portions is formed such that boundary lines between the adjacent pattern portions become parallel and the lenticular lens sheet on which a plurality of lenses are formed such that groove lines between the adjacent lenses become parallel and which is transparent by placing the plate on a table and overlaying the lenticular lens sheet on the plate;
- calculating, by an adjustment amount calculation unit based on a relationship between the boundary lines of the pattern formed on the plate and the groove lines of the lenticular lens sheet that are in a state in which the lenticular lens sheet is overlaid on the plate placed on the table, an adjustment amount for a cocking adjustment unit that adjusts a relative angle between the plate and the lenticular lens sheet;
- and
- adjusting, by a plate cylinder cocking device that the cocking adjustment unit comprises, an axial-direction orientation of a plate cylinder to which the plate is attached based on the calculated adjustment amount.

- a cocking adjustment unit that adjusts a relative angle between a plate on which a pattern formed from a plurality of pattern portions is formed such that boundary lines between the adjacent pattern portions become parallel and the lenticular lens sheet on which a plurality of lenses are formed such that groove lines between the adjacent lenses become parallel and which is transparent;
- a table on which the plate and the lenticular lens sheet are placed;
- and
- an adjustment amount calculation unit that calculates an adjustment amount for the cocking adjustment unit based on a relationship between the boundary lines of the pattern formed on the plate and the groove lines of the lenticular lens sheet that are in a state in which the lenticular lens sheet is overlaid on the plate placed on the table,
- wherein the cocking adjustment unit comprises a sheet skewing device that adjusts a conveyance angle of the lenticular lens sheet based on the adjustment amount calculated by the adjustment amount calculation unit.
