The specific embodiment

Below in conjunction with accompanying drawing and the specific embodiment the utility model is described in further detail:

By Fig. 1, Fig. 2 as seen: the utility model comprises: thin plate 1; The material of described thin plate 1 is stainless steel or aluminum alloy materials; Be processed to form the latticed figure 11 identical with requiring figure in the front of described thin plate 1; Reverse side at described thin plate is processed to form the full hollow out figure 12 identical with requiring figure.

The thickness of the latticed figure 11 in described front and full hollow out figure 12 and the ratio of thin plate 1 gross thickness are between 20%--80%.

The opening shape of described latticed figure 11 can become, and can be circular, square or any shape changeable; Wire diameter in the described latticed figure 11 is between 0.025mm and 0.3mm.

The utility model is processed to form latticed figure in the front of the thin plate of stainless steel or alloy aluminum, is processed to form the full hollow out figure identical with the actual graphical of printing at reverse side (another side).Stainless steel after the processing or aluminium alloy sheet are fixed on the metal screen frame, are processed to form final stainless steel or the different Printing screen of aluminum alloy two-side figure.

Technical essential of the present utility model is divided into three parts:

One, be in stainless steel or the aluminium-containing alloy thin plate processing method by exposure etching or laser engraving, (double-edged thickness ratio is between the 20%--80% of thin plate gross thickness to process respectively the thickness difference on the positive and negative two sides of thin plate, require to change according to final printing-ink thickness), the Printing screen of figure different (one side is processed to form the latticed figure of variable element, and another side is processed to form the full hollow out figure identical with the actual graphical of printing).

Two, be processed to form the latticed figure of variable element at the same plate of throwing the net: the opening shape of grid is variable, can realize the figure that all types of user such as circle, square, any shape changeable need.This high limit of size as required can be larger from 0.025mm to 0.3mm(for wire diameter in the grid pattern, usually is no more than 0.3mm).But aperture opening ratio can according to the specific requirement Set arbitrarily, reach as high as more than 90%.This is that the traditional printing web plate can't be realized.

Three, select the thickness proportion of thickness and grid pattern layer and the hollow out graph layer of stainless steel or aluminium alloy sheet by quantitative control, the utility model can accurate quantification be controlled the thickness of final printing-ink.

Manufacture method of the present utility model is divided into two kinds, is respectively described below:

The metal etch method:

1, require to choose stainless steel or the aluminium alloy sheet of different-thickness according to the technical parameter of web plate, the thickness of slab selection range is between 0.03mm-0.3mm, and the thickness of slab value is determined by the final printing thickness of web plate.

2, the surface with thin plate processes pre-treatment, the pollutants such as place to go surface dirt, greasy dirt, oxide-film.

3, stick light-sensitive surface on the surface of thin plate with laminator.

4, use parallel exposing machine, the two-sided different figure that is made on the photographic film is transferred on the light-sensitive surface of thin sheet surface, or adopt stainless steel web plate laser straight to connect exposure machine two-sided different figure is fabricated directly on the light-sensitive surface of thin sheet surface.

5, use stainless steel or aluminium alloy etching machine, thin plate is developed, etching, moves back film and process, temperature, the concentration of the etching solution during by control etching machine etching and processing, etching period parameter (30 seconds to 300 seconds or longer, depend on that light-sensitive surface is to the shock-resistant ability of etching solution), the parameters such as sprinkler pressure quantitatively process the thin plate that meets the designing requirement of two-sided different figure Thickness Ratio.

6, the thin plate that processes is fixed on the final web plate finished product of formation on the metal screen frame with glue special.

The direct engraving method of laser:

3, use laser engraving equipment, process respectively two-sided different figure on the surface of thin plate, and control the thickness of two-side graph by the working depth of regulating laser.

4, the thin plate that processes is fixed on the final web plate finished product of formation on the metal screen frame with glue.

Existing the being associated property of graphic parameter on two surfaces of the utility model has again autonomous behavior separately, makes it possible to can produce specific Printing screen by setting these parameters.Use the thickness and the high-precision dimension of picture that print out the printing ink (slurry) that meets customer requirements that this Printing screen can be quantitative.Because the metallic character of stainless steel and alloy aluminum is more prone to so that print the technology controlling and process of processing, quality assurance is more reliable simultaneously.

The defective of the bad performances such as the utility model has solved fundamentally that the tension force of traditional silk screen is unstable, and printing precision is low, and is high to temperature, moisture sensitivity, wears no resistance, and memory time is short.The manufacturing cost of the utility model product is lower than present traditional silk screen and nickel screen simultaneously, and the batch production that is more suitable in all kinds of printing industry is used.
