Document Type and Number:
Japanese Patent JP2017061107
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a technique which can maintain printing quality during continuous printing in off-set printing using a blanket even with any pattern density of a pattern to be printed.SOLUTION: An off-set printing device which prints a pattern formed on a plate installed on a plate stage unit 4 onto a workpiece 17 that is a printing object body includes: a split-type drying unit 15 which has a light source for drying a solvent absorbed from ink by a blanket 12; and a control part 19 which, when a pattern density is higher, controls the irradiation amount of light from the light source of the split type drying unit 15 so that a density of the solvent absorbed by the blanket 12 becomes smaller in comparison to a case where the pattern density is lower in accordance with the pattern density during continuous printing of the pattern.SELECTED DRAWING: Figure 7
