摘要:
There is described a cylinder body (10) for orienting magnetic flakes contained in an ink or varnish vehicle applied on a sheet-like or web-like substrate, which cylinder body (10) has a plurality of magnetic-field-generating devices (50, 60) disposed on an outer circumference of the cylinder body (10). The cylinder body (10) comprises a plurality of distinct annular supporting rings (40) distributed axially along a common shaft member (20), each annular supporting ring (40) carrying a set of magnetic-field-generating devices (50, 60) which are distributed circumferentially on an outer circumference of the annular supporting rings (40).

The invention discloses a varnish coating device that utilizes an ordinary conventional digital stencil printing apparatus, such that anyone can easily apply a uniform film of a viscous coating onto a predetermined area of, for instance, covers and surfaces of printed products. The invention functions as a varnish coating device, in place of a drum unit, when a varnish coating unit is mounted on a mounting section of a printing apparatus main body. The varnish coating unit has: a coating roller that coats the surface of printed paper with a transparent varnish liquid and feeds out the paper; a supply device having a doctor roller that forms a liquid pool on the coating roller and that supplies varnish liquid to form a coating in a predetermined thickness over a predetermined area of the surface of the coating roller; a cradle that detachably supports a varnish container; and a pumping device.

A printing method and a printing apparatus including a stencil printing apparatus and so on. Focusing on the relationship that exists between copy number and master position displacement that occurs during printing, by determining by pretest and setting top-bottom shift correction values in accordance with parameters including copy number that affect printed master position displacement in the direction of rotation of a plate cylinder, and during printing, utilizing conventionally used top-bottom shift means to automatically execute top-bottom shift correction in accordance with the set top-bottom shift correction values, printing position displacement can be prevented from occurring, waste of master and printing medium such as paper can be eliminated and, in addition, the operation time can be shortened and the number of operation steps can be reduced. The CPU of control means, each time the copy number counted by a paper discharge sensor reaches a predetermined copy number, reads a top-bottom shift correction value corresponding to a predetermined copy number from a ROM, and during printing, controls a top-bottom shift motor of top-bottom shift means to execute a top-bottom shift correction in accordance with the read top-bottom shift correction value.
摘要:
A printing device comprising a stencil printing device which is excellent in operativity, in which a print drum with UV ink and non-UV ink can be used in a single stencil printing device. The printing device has a stencil printing control device and UV irradiation control device in which a drum unit ink type identifying sensor, which detects whether the print drum attached to the stencil printing device main body is a print drum unit for UV ink or a drum unit for non-UV ink, is used to operate at least a UV lamp, of the UV lamp and a UV auxiliary lamp, and to irradiate UV light when attachment of the drum unit for UV ink is detected, or to stop the operation of the UV lamp and UV auxiliary lamp when attachment of the print drum unit for non-UV ink is detected.

To make the stencil printing at a stabilized density from the start of printing in a stencil printing where a plurality of kinds of inks different from each other in volatility and/or viscosity are used. Information representing the volatility and/or viscosity of ink is stored in a storage means of an ink container, while the stored information representing the volatility and/or viscosity of ink is read out, and at the same time, the ceasing time from interruption of printing to resumption of the same is measured, and the printing pressure is controlled according to the ceasing time and the information representing the volatility and/or viscosity of ink.
