The difference between traditional Chinese printing and screen printing
When many customers with printing needs need to find a suitable machine, they still do not know how to print their products. In fact, the four traditional Chinese printing methods are divided into letterpress, gravure, lithography, and stencil. However, with the development of computer technology and equipment, there are laser printing and inkjet printing. Such new methods have no imprinting action during printing, which is called non-contact or non-pressure printing.
The difference between silk screen and printing?
Screen printing: The full name of screen printing belongs to stencil printing. It is called the four major printing methods together with flat printing, letterpress printing and gravure printing. Stencil printing includes transcription, perforated pattern, spray pattern and screen printing. The principle of stencil printing is: during printing, the printing plate (paper film plate or other plate base with holes through which the ink can pass through) transfers the ink through the holes of the stencil to the substrate (paper, ceramics, etc.) through a certain pressure. ) to form images or text.
Printing (Printing, Graphic Arts, also used Graphic Communications, that is, graphic communication) is the process of plate making, ink application, pressure, etc. of manuscripts such as text, drawings, photos, and anti-counterfeiting, so that the ink is transferred to paper, fabrics, plastics, etc. On the surface of leather and other materials, the technology of mass copying the content of the original.
After understanding the difference between silk screen printing and printing, let's talk about our silk screen printing [stencil printing]
Screen printing belongs to stencil printing, which is to stretch silk fabric, synthetic fiber fabric or metal mesh on the screen frame, and make screen printing plate by hand-engraving paint film or photochemical plate making.
Modern screen printing technology uses photosensitive materials to make screen printing plates by means of photolithography (so that the screen holes in the graphic part of the screen printing plate are through holes, and the screen holes in the non-graphic part are blocked. live). During printing, through the extrusion of the scraper, the ink is transferred to the substrate through the mesh of the graphic part to form the same graphic as the original. "Universal printing method".
Main advantages:
1. The printing adaptability is extremely strong. The surface of different printing materials such as metal, plastic, ceramics, glass, paper, and fabric can be printed on the printing surface of different shapes, regardless of the size of the printing area, and any other printing method cannot be compared and replaced. ;
2. The process is simple, the investment is small, and the effect is quick;
3. Thick ink layer, strong three-dimensional effect, good ink adhesion and bright color;
4. Various types of inks can be used: oil-based, water-based, synthetic resin emulsion type, powder and other types;
5. Strong light resistance and better color formation than offset printing;
6. The printing format is large;
7. With anti-counterfeiting function.
Limitations:
1. Originals that are not suitable for reproducing fine lines and dots;
2. The registration accuracy is weaker than other printing;
3. The speed is slow;
4. Only suitable for monochromatic color originals with crisp text and lines and color originals with high contrast and clear layers.
In general, the range of screen printing applications is very broad. In addition to water and air (including other liquids and gases), any kind of object can be used as a substrate. Someone once said this when evaluating screen printing: If you want to find the ideal printing method on earth to achieve the purpose of printing, it is likely to be the screen printing method.
Specifically, screen printing is mainly used in the following aspects: paper printing, plastics, wood products, metal products, glass and ceramic products, signs, circuit boards, printing and dyeing, leather products and electronic fields.
Here comes the point
Introduce this CCD automatic alignment screen printing machine VT6090P-1 that can be used for thick film circuits
CCD image positioning upgrade, the accuracy can reach 0.02mm. This machine adopts a fully automatic CCD image positioning system, the substrate does not need to be placed manually, the platform is automatically displaced, the product position is automatically recognized, and the deviation is automatically corrected. Suitable for high-precision product printing. Such as: ceramic thick film circuit, biological circuit, liquid crystal display (LCD), signal display (LED), electroluminescence (EL), nameplate signs, glass printing, CD discs and other high-precision electronic substrates such as flat printing. Single-sided circuit, liquid green oil, wet film, character, EL and flexible circuit board, etc.
