Description

Printing device with seamless rubber printing plate

Technical Field

The utility model belongs to the technical field of the printing plate and specifically relates to a printing device that seamless rubber printing plate and have this seamless rubber printing plate is related to.

Background

At present, the printing method mainly comprises the following 4 methods:

1. letterpress printing:

the printing method has the advantages of more characters, fewer photos and pictures, more change opportunities of the characters, and less printing quantity-hundreds or thousands of printing products which are suitable for letterpress printing. The number of types of printing is not more than thirty thousand, and the number of fine picture printing is not more than seven or eight thousand. The printing picture must be made of powder paper to obtain perfect dots. Therefore, it is not possible to print images on inexpensive paper and a fine effect is desired. When the letterpress flat cable form is used, the junction of lines is easy to separate and disjoint, which is a common defect. In addition, too high printing pressure or too soft surface of the pressure cylinder during printing can cause the back of the printed sheet of the finished product to have relief-like protrusions, which greatly reduces the quality of the printed product.

2. Intaglio printing:

gravure printing is suitable for printing publications of high quality and value, and is highly pleasing like photographic prints, whether four-color or black and white. Since plate making is expensive and the amount of printing must be large, the minimum one of the five prints used in hong Kong is one of the fewest possible.

3. Screen printing:

since the screen printing ink is particularly thick, it is most suitable for printing pieces with special effects, and the quantity is not large, and the ink color needs to be thick. But also can be printed on the solid such as square boxes, round goblets, cans and the like. The printing bottom can be printed with cloth, a fast handle, a clamping plate, a plastic sheet, a metal sheet, glass and the like besides paper, and is commonly used for printing silk banners, T-shirts, shoe boxes, soda goblets, circuit boards and the like. All the printing characteristics are not available in other printing methods.

4. Offset printing:

the printing of the gummed paper is only suitable for printing gummed bags, hand drawers and large and small plastic packages. The input printer for the printed sheets is not a single sheet but a roll, and the sheets are cut one by one after printing. The minuteness of printing points and lines is far less than that of letterpress printing and offset printing, and the offset printing cannot be used for printing books and journals.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a seamless rubber printing plate and have printing device of this seamless rubber printing plate in order to overcome the defect that above-mentioned prior art exists.

The purpose of the utility model can be realized through the following technical scheme:

a seamless rubber printing plate comprises a rubber layer, an adhesive layer and a steel pipe layer, wherein the rubber layer is wrapped with the steel pipe layer through the adhesive layer.

Preferably, the bonding layer is an adhesive.

Preferably, the thickness of the rubber layer is 0.3-2 mm.

Preferably, the thickness of the rubber layer is 1 mm.

Preferably, the rubber layer is a rubber layer with rubber hardness of HS 20-HS 80.

Preferably, the rubber layer is a rubber layer with the rubber hardness of HS 50.

The printing device of the seamless rubber printing plate comprises the seamless rubber printing plate, an anilox roller, an ink tank, a stamping roller and a printing stock, wherein the seamless rubber printing plate is respectively tangent to the anilox roller and the stamping roller, the anilox roller is partially immersed in the ink tank, and the printing stock is arranged between the seamless rubber printing plate and the stamping roller.

Compared with the prior art, the utility model has the advantages of it is following:

1. seamless flexographic rubber plates can replace existing offset and gravure printing.

2. The electroplating process is carried out in the seamless rubber plate production process different from that of a gravure plate roller, and the discharge of heavy metals such as chromium, nickel, copper and the like can not be generated. No damage to environment.

3. The ink consumption of the seamless rubber printing plate is less than that of gravure printing, the volatility of the solvent is higher, and the residual quantity of the solvent is particularly low.

4. With the reduction of the used ink, the printing cost is saved, the energy and time for drying the ink during printing can be reduced, and the printing speed is improved.

5. The seamless rubber plate can solve the problem of the traditional flexible printing seam, can be accurately registered, can save double faced adhesive tape and improve the printing efficiency.
