Problems solved by technology

[0006] In this printing method, the ink transferred to the auxiliary roller is dipped in a solvent to wipe it off, and the solvent adhering to the auxiliary roller is scraped off, and the normal printing state is obtained by repeating this operation, However, when the operation is repeated, there is a problem that the concentration of the ink in the solvent gradually increases, and the wiping member becomes dirty, and the cleanliness of the auxiliary roller deteriorates. The problem that normal operation cannot be obtained under the same conditions as the body
[0007] In addition, if the printing speed is increased, the operation speed of the auxiliary roller will also increase, and there is a problem that the solvent or the ink that is wiped may splash
[0008] In addition, it is necessary to add a mechanism to move the impression cylinder of the printing press itself up and down, and the auxiliary roller device must also move together with the solvent container, and there are also problems that the mechanism is complicated and large

Abstract

Excess ink or an ink bleeding is removed by winding a band film (F), which is so provided as to be capable of being wound and unwound, around a trapping roller (11) installed opposite to a blanket (4) of a blanket wheel (3) through a contacting / retreating mechanism (12), thereby contacting the film (F) with the blanket (4). Consequently, it is possible to trap the ink by contacting always clean film with the blanket and also achieve the ink trapping with a simple mechanism for contacting and retreating the trapping roller.

Description

technical field [0001] The present invention relates to an ink collecting method and its device, which can easily remove excess ink or oozing ink without using a printed object as a product from the time of startup or restart of the printing press to the normal printing state. It is especially suitable for printing machines used in beverage cans to prevent substandard products. Background technique [0002] In the case of using a printing machine to print on the printed object, when the printing machine is started, or when it is restarted after a color change or plate change, etc., due to changes in the supply amount of ink, ink may adhere excessively or ink may Bleeding until it becomes a normal printing state can not form a product. [0003] Therefore, the same printed body as the product is also supplied and discarded during the period from the time of startup or restart to the normal printing state. [0004] Since the number of printed objects that must be supplied and...
