Vacuum flat silk screen printer

Screen printing is a printing technique that uses a woven mesh to support an ink-blocking stencil. The attached stencil forms open areas of mesh that transfer ink or other printable materials which can be pressed through the mesh as a sharp-edged image onto a substrate. A fill blade or squeegee is moved across the screen stencil, forcing or pumping ink into the mesh openings for transfer by capillary action during the squeegee stroke.

 

Screen printing is also a stencil method of print making in which a design is imposed on a screen of polyester or other fine mesh, with blank areas coated with an impermeable substance, and ink is forced into the mesh openings of the mesh by the fill blade or squeegee and onto the printing surface during the squeegee stroke. It is also known as silkscreen,serigraphy, and serigraph printing. You can also have more than one colour printing, for example you could have a striped printing.

 

Printing technique

A screen is made of a piece of mesh stretched over a frame. A stencil is formed by blocking off parts of the screen in the negative image of the design to be printed; that is, the open spaces are where the ink will appear on the substrate.

  

Textile items printed with multi-colour designs often use a wet on wet technique, or colors dried while on the press, while graphic items are allowed to dry between colours that are then printed with another screen and often in a different color after the product is re-aligned on the press.

 

Most screens are ready for recoating at this stage, but sometimes screens will have to undergo a further step in the reclaiming process called dehazing. This additional step removes haze or "ghost images" left behind in the screen once the emulsion has been removed. Ghost images tend to faintly outline the open areas of previous stencils, hence the name. They are the result of ink residue trapped in the mesh, often in the knuckles of the mesh (the points where threads cross).

 

While the public thinks of garments in conjunction with screenprinting, the technique is used on tens of thousands of items, including decals, clock and watch faces, balloons, and many other products. The technique has even been adapted for more advanced uses, such as laying down conductors and resistors in multi-layer circuits using thin ceramic layers as the substrate. flat screen printer

Before printing occurs, the frame and screen must undergo the pre-press process, in which an emulsion is 'scooped' across the mesh and the 'exposure unit' burns away the unnecessary emulsion leaving behind a clean area in the mesh with the identical shape as the desired image. The surface (commonly referred to as a pallet) that the substrate will be printed against is coated with a wide 'pallet tape'. This serves to protect the 'pallet' from any unwanted ink leaking through the substrate and potentially staining the 'pallet' or transferring unwanted ink onto the next substrate. Next, the screen and frame are lined with a tape. The type of tape used in for this purpose often depends upon the ink that is to be printed onto the substrate. These aggressive tapes are generally used for UV and water-based inks due to the inks' lower viscosities. The last process in the 'pre-press' is blocking out any unwanted 'pin-holes' in the emulsion. If these holes are left in the emulsion, the ink will continue through and leave unwanted marks. To block out these holes, materials such as tapes, specialty emulsions and 'block-out pens' may be used effectively.

 

The screen is placed atop a substrate. Ink is placed on top of the screen, and a floodbar is used to push the ink through the holes in the mesh. The operator begins with the fill bar at the rear of the screen and behind a reservoir of ink. The operator lifts the screen to prevent contact with the substrate and then using a slight amount of downward force pulls the fill bar to the front of the screen. This effectively fills the mesh openings with ink and moves the ink reservoir to the front of the screen. The operator then uses a squeegee (rubber blade) to move the mesh down to the substrate and pushes the squeegee to the rear of the screen. The ink that is in the mesh opening is pumped or squeezed by capillary action to the substrate in a controlled and prescribed amount, i.e. the wet ink deposit is proportional to the thickness of the mesh and or stencil. As the squeegee moves toward the rear of the screen the tension of the mesh pulls the mesh up away from the substrate (called snap-off) leaving the ink upon the substrate surface. flat screen printer

 

Versatility

Screenprinting is more versatile than traditional printing techniques. The surface does not have to be printed under pressure, unlike etching or lithography, and it does not have to be planar. Different inks can be used to work with a variety of materials, such as textiles, ceramics, wood, paper, glass, metal, and plastic. As a result, screenprinting is used in many different industries, including:

Balloons

Clothing

Decals

Medical devices

Printed electronics, including circuit board printing

Product labels

Signs and displays

Snowboard graphics

Textile fabric

Thick film technology

 

Screen printing press

Vacuum flat silk screen printer

To print multiple copies of the screen design on garments in an efficient manner, amateur and professional printers usually use a screen printing press. Many companies offer simple to sophisticated printing presses. Most of these presses are manual. A few that are industrial-grade-automatic printers require minimal manual labor and increase production significantly.

 

screen printing market space

China from the 20th century, 80 years, the speed of screen printing materials, equipment, technology research and development, so that screen-printing with flexo printing, offset printing, gravure played an advantage in competition. Rate of 7% annual increase. Currently there are about More than 70% of the wide format color screen printing with spot-color printing, nearly 30% using four-color overprint, and the proportion of four-color overprint is still increasing steadily. Industry survey showed that 70% of the annual output value of enterprises 100 million. But China's current total output value of the printing screen printing production value less than 2%, which have great potential to be tapped and broad development prospects.

 

screen printing applications

Screen Printing in commercial advertising, there will be more market, some large companies, especially electric companies,tobacco companies promote their image in order to attach great importance to the role of advertising. Advertising time and to some extent determine the quality of the company's share of the market. Therefore, all kinds of electrical advertising,packaging and advertising, outdoor advertising, commercial ads to screen printing provides a broad space. In the commercial competition, because the large-scale outdoor advertising a wide field of vision, effective and taken seriously. So, as our screen printing large color outdoor ads along with the development of commercial advertising, the increasing volume showed large, cheap, colorful, save a long period, and fast delivery advantages, more and more cities are planning departments,advertising approved by regulatory agencies, attracting a lot of advertisers.

 

Screen Printing What is the principle
Screen printing by the five elements, namely screen printing plate , squeegee blade , ink, printing units and substrates . Screen printing basic principle is : the use of screen printing ink through the mesh graphic part , non- graphic part mesh impervious basic principles of ink for printing . Screen printing when printing on one end into the ink scraper with squeegee in screen printing ink on the site exert a certain pressure , while the other end of the plate toward the screen moves . Ink is on the move from the graphic part of the blade in the extrusion of the mesh to the substrate . The viscosity of the ink blots leaving the role of fixing a certain range, the printing process of screen printing squeegee always line contact and substrate , the contact line and moves with the blade , as the screen printing plate with the substrate to maintain a certain gap between such a screen printing plate by its own tension on the blade produced a reaction , this reaction is called resilience . Since the role of resilience , so that screen printing plate and movable substrate was only line contact , while other parts of screen printed version is out of state with the substrate . Rupture of the ink and screen movement to ensure accuracy and avoid printing size , soiled substrates . When the scraper scraped and lift the entire layout , but also lift the screen printing plate and ink scuffing back to the initial position. So far as a printed itinerary.

 

The main features of screen printing
Vacuum flat silk screen printer

Screen printing features can be summarized in the following aspects:
1. screen printing can use many types of ink. Namely: oil, water, a synthetic resin emulsion, powders, and other various types of ink.
2. layout soft. Screen printing layout soft and has a certain flexibility is not only suitable for use in paper and fabric printing and other soft articles, but also suitable for use in printing on rigid materials, such as: glass, ceramics and so on.
3. silkscreen imprint force is small. As used in the printing pressure is small, so it is suitable for printing on the body easily broken cart.
4. ink layer is thick, strong coverage.
5. shape of the substrate surface without restrictions and area size. Seen from the foregoing, screen printing can not be printed on the plane, and can be printed on the surface or spherical surface; It is not only suitable for printing on small objects, but also suitable for printing on large objects. This printing method has great flexibility and broad applicability.
