Problems solved by technology

[0008] The disadvantage of the above-mentioned printing screen manufacturing, use and especially storage method is that after the printing screen is imaged by inkjet printing or exposure and development means, the mechanical tension of the printing screen may change, that is, the screen frame The mechanical tension determined during the stretching process may vary
Also screen tension may change due to storage of imaged printing screens

Embodiment Construction

[0042] attached figure 1 Shown is a schematic diagram of the screen printing screen frame manufacturing and imaging device of the present invention. The device has an accommodating device 1 for accommodating a screen frame 2, for example, the screen frame 2 is composed of an upper component 21 and a lower component 22, and these components can be engaged with each other through matching pins 23 and matching holes 24.

[0043] In order to produce a printing screen, for example, a section 4b of the screen fabric 4a can be passed from the screen fabric roll 4 through the guide device 5 along the Put it in the direction 101 between the upper member 21 and the lower member 22 of the screen frame 2, and then put the two members 21 and 22 together in the second step, and fix and clamp the screen fabric along the edge of the screen frame.

[0044] For example, a clamping device or a screwing device not shown in the figure may also be used to fix the screen frame members 21, 22 to eac...

Abstract

The invention relates to a method for manufacturing printed screens used in screen printing machine, including: fixing and positioning a screen frame (2) provided with filter screen (4a) or screen frame (2) which will be provided with filter screen (4a) in the next step, where position and state of the frame are detected. The filter screen (4a) of the frame is mechanically tensioned, and forces exerted on the screen are detected. The detected forces are stored as force data in a memory device (10), which is attached to the frame. The frame is removed from the accommodating device. The invention also relates to a method of using the printed screens used in screen printing machine, a device for manufacturing or using the printed screen, a screen frame and a screen printing machine.

Description

technical field [0001] The invention relates to a method for manufacturing and using a printing screen applied to a screen printing machine, especially flat screen printing, and a device for manufacturing or using the printing screen. The invention also relates to a screen frame (Siebrahmen) and a screen printing machine. Background technique [0002] Single or multicolor printing of cans, bottles, tubes, CDs or DVDs, electronics, clothing (eg T-shirts), hats or general substrates by screen printing has been common practice for several years. In most cases, screen printing units working with flat screens are used. The wire mesh fabric is tightened and fixed on a stable frame with a certain mechanical pre-tightening force to make a flat mesh. [0003] In order to be able to use the printing screen thus obtained in a printing press, it is necessary to place the image to be printed in the screen fabric, thereby forming in the screen fabric imaged parts which are pervious to i...
