Description
Technical Field
The present invention relates to a structure of a screen printing plate, and more particularly to a screen printing plate with a new positioning structure.
Background
FIG. 1a is a schematic diagram illustrating a first printing process of a prior art halftone printing plate; FIG. 1b is a schematic diagram illustrating a second printing process of a prior art printing screen; fig. 1c is a schematic diagram for explaining a third printing process of a printing screen in the prior art. Referring to fig. 1a to 1c, most of the prior art screen printing adopts off-plate printing, i.e. the screen 1 is placed above the object 2 to be printed, and then the paste or ink is scraped from the pattern area a1 on the mesh 101 to the object 2 to be printed by the scraper 3 to form a printed pattern. As can be seen from fig. 1a, the set stroke of the scraper 3 is greater than the area of the object to be printed 2, and when the scraper 3 applies a downward pressing force, the mesh 101 is pressed, so as to generate a pressure point P1 and a pressure point P2, the pressure point P1 is the force point between the scraper 3 and the mesh 101, and the pressure point P2 is the bending point of the edge of the mesh 101 and the object to be printed 2, at this time, if the periphery of the object to be printed 2 is relatively sharp, the mesh 101 will be damaged by the pressure point P2.
As can be seen from fig. 1b, the doctor blade 3 applies a force from the pressure point P2 to scrape the paste or ink from the pattern area a1 on the mesh 101 onto the object 2 to be printed to form a printed pattern, and at this time, if the downward pressure of the doctor blade 3 is too large, the printing speed is fast, and the paste or ink is easy to overflow from the knife inlet, i.e., the pressure point P2. As can be seen from fig. 1c, the stroke of the doctor blade 3 finally reaches the pressure point P3.
As can be seen from the above-mentioned prior art, the current screen printing plate structure is damaged by the force applied by the scraper during the printing process. For the above reasons, it is an object to provide a screen printing plate structure capable of enhancing the resistance of a scraper during a printing process, so as to prevent the printing screen printing plate from being damaged.
