Description

Printing device {printer}

The present invention relates to a printing apparatus, and more particularly to a printing apparatus made possible to adjust the amount of water supplied to the printing plate.

The printing apparatus is a device which allows printing to prints such as catalogues, calendars, and posters.

Such a printing apparatus has a direct printing method in which ink is imprinted on a printing plate and transferred to paper, and an indirect printing method in which ink is imbedded on a printing plate and transferred to a rubber copper and then transferred to paper.

Among them, the drawing board portion and the non-drawing line portion are formed in the printing plate of the printing apparatus in which the indirect printing method is performed.

In such a printing apparatus, water and ink are supplied onto a printing plate on which a line portion and a non-line portion are formed, and printing is performed by using the repulsive force of the water and ink.

Then, only the ink on the printing plate is lipophilic only, and the non-fire line is hydrophilic so that water is printed.

At this time, the caustic portion of the printing plate is made of an ink-soluble material so that only ink can be buried even when water and ink are in contact.

In addition, the non-ignition portion of the printing plate is made of a water-soluble material so that only water can be buried even when water and ink are in contact with each other.
