Problems solved by technology

Here, however, there is the disadvantage that the ink adheres very little to the surface of the print, so that a wipe-resistant bond cannot be achieved
However, the irradiation intensity of the two exposure heads is not enough to fully cure the printed image line by line

Embodiment Construction

[0016] figure 1 and figure 2 A printer according to the invention with a printing head and an exposure head connected thereto is shown in longitudinal section and plan view. The printer according to the invention is preferably designed as a desktop printer and essentially consists of a housing slot 1 and a housing upper part 2 in which a printer support with side walls 3 , 4 is arranged. The two side walls are separated by an angular beam 5 . A slide rail 6 is attached to the printer stand, on which slide carriages 7, 7.1 are mounted. The carriages 7 , 7 . 1 are driven by a motor 10 via a ring-shaped traction device 9 , which is steered here by deflection wheels 11 . Mounted on the carriage 7, 7.1 are the printing heads 12, 12.1 and beside them the exposure heads 13, 13.1. Between them is a heat shield 14, 14.1, which protects the print heads 12, 12.1 from the thermal radiation of the exposure heads 13, 13.1.

Abstract

The invention relates to a method for printing with an ink printer which, during printing operation, moves its print head (12, 12.1) and an exposure head (13, 13.1) connected to it in a traversing manner between a first housing side and a second housing side and, on its path to the first housing side, sprays light-curable ink in a targeted manner onto a printing material, while the exposure head (13, 13.1) irradiates the light-curable ink which has been sprayed onto the printing material. In order to produce a sharp and thoroughly cured printed image, the exposure head (13, 13.1) again irradiates the light-curable ink which has been sprayed onto the printing material, while the print head (12, 12.1) is moved with the exposure head (13, 13.1) to the second housing side, wherein subsequently the printing material is transported transversely with respect to the movement direction of the print head (12, 12.1).

Description

technical field [0001] The invention relates to a method for marking printed matter by means of an inkjet printer operating with light-curing inks, the inkjet printer having a slide that moves back and forth between two housing sides, on which slide The printing head and the exposure head; also have a conveying device for moving the printed matter in a row, where, during the going of the carriage moving to the first housing side of the printing head, the ink is sprayed onto the printed matter, and the exposure head irradiates the sprayed material. The ink on it allows it to cure. Background technique [0002] It is well known to use photocurable inks when printing with inkjet printers. This ink contains a plurality of photoinitiators tuned to a predetermined short wavelength of light. An inkjet printer operable with photocurable ink has an exposure head for irradiating and exposing the photocurable ink. During exposure, the exposing head moves back and forth between the t...
