Title:
DRY OFFSET INTAGLIO PRINTING MACHINE
Document Type and Number:
Japanese Patent JPS6127257
Kind Code:
A
Abstract:

PURPOSE: To improve the registering accuracy between an intaglio printing and a offset printing by disposing each cylinder such that the line connecting the shaft centres of an impression cylinder and an intaglio cylinder and the line connecting the shaft centres of the intaglio cylinder and an offset cylinder are intersected at an angle of approximately 90°.

CONSTITUTION: An intaglio cylinder 32 equipped with an intaglio form is arranged with its periphery being pressed contacted to a periphery of a paper carrying side of an impression cylinder 31, and an offset cylinder 33 disposed to its periphery with the dry offset cylinder 13 is arranged with its periphery disposed opposed to the periphery of the intaglio sylinder 32. Each cylinder 31, 32, 33 is disposed such that the line connecting the shaft centres of the intaglio cylinder 32 and the offset cylinder, and the line connecting the shaft centres of the intaglio cylinder 32 and the impressing cylinder 31 are intersected at an angle of approximately 90°. A very strong pressure between the impression cylinder 31 and the intaglio cylinder 32 is acted in the gravity direction, and there is no displacement of the intaglio cylinder centre due to a bearing clearance of the intaglio cylinder 32 and influence force against the offset cylinder 33 is little. Therefore, a registering accuracy is maintained and the quality of a printed goods is improved when a picture is transfered from the offset cylinder to the intaglio surface.
