How to distinguish pad printing and screen label printingPad printing is one of the special printing methods in China, and screen printing is one of the four major printing methods in China. It is known as the four printing methods together with lithographic printing, letterpress printing and intaglio printing. Screen printing belongs to plate printing, which is one of the special printing methods in our country. So what's the difference between these printing methods? As shown in the following seven aspects of difference:I. DefinitionPad printing belongs to one of the special printing methods. The selection of steel (or copper, thermoplastic) gravure printing, the use of silicone rubber materials made of inclined pad printing head, the ink in the gravure printing is dipped into the surface of the pad printing head, and then the surface of the necessary object can be pressed to print out text, pattern design.

In recent years, the screen printing machine has flourished at a very fast speed, and the industry competition has become increasingly fierce, and the quality of printed products has become a key factor in the competition. So we have to keep our eyes open and choose a screen printer. For many screen printing machine manufacturers, the addition of new high-quality screen printing equipment is imminent. At present, there are many kinds of screen printing machines on the market, and the specifications and types are dizzying, but the quality is uneven, so how can we select good products from them? Let's take a look at it today

In most of the operation of the use of screen printing machine customer feedback, sometimes the screen printing machine out of a small problem on the urgent call, often they can solve the problem in three or two minutes. By the time they do, it takes too long. In fact, it is better to teach people to fish than to give them fish. Instead of worrying themselves every time there is a problem, I think what we need more is to be able to solve some small problems by ourselves. Here are some common faults and solutions for screen printing machines!Common screen printing machine faults and troubleshooting methods1. The screen printing machine starts immediately without stepping on the screen printing machine foot switch when opening the semi-automatic, and the main reasons for such failures are mostly because the foot switch is damaged or the foot switch socket has water, resulting in short-term short circuit caused by such a failure. In addition, there may be a problem with the manual open button switch, and the repair method is to replace the new manual open switch or socket or button switch, or remove the open switch to repair the relevant damaged parts.

Pad printing machine has the role of high efficiency, environmental protection and energy saving. It can be divided into vertical pad printing machine, inclined arm pad printing machine, rotary pad printing machine, four-column pad printing machine and automatic pad printing machine. Mainly used in the electronic processing industry, printed circuit board screen logo, instrument shell panel logo, circuit board processing process solder paste printing. So what problems need to pay attention to before the pad printing machine starts?1, the pad printing machine must be cleaned when in use, after cleaning treatment to make the pad printing machine better use, to avoid the problem of dust caused by corrosion of the machine, the service life can also be extended. The inside of the pad printing machine must be in a normal state, and there must be no foreign body, otherwise it will certainly lead to the problem of obstruction, and only by ensuring that it is in a normal state can it be better used.

1. Quality requirements of silk screen printing machine original manuscriptThe original manuscript is the basis of printing and reproduction, and the quality of the original manuscript directly affects the printing and reproduction. When receiving the business order, accepting the original manuscript and carrying out the process design, the original manuscript submitted by the customer should be carefully reviewed to determine whether it meets the requirements. Different printing methods have different requirements for the original manuscript, such as whether the original manuscript meets the characteristics of the printing method; Whether it is suitable for the reproducible range of process operations in plate making and printing. That is, the selection of patterns, text and colors in the original manuscript must first meet the production requirements of plate making and printing, and then be suitable for the actual level of equipment, materials and operations of the printing manufacturer; Some even have to consider whether they can meet the specific practical standards of printed matter. Only in this way can we ensure that the printed matter reaches a more ideal quality standard.

Pad printing machine should pay attention to daily maintenance, in order to extend its service life and bring great benefits to the enterprise. At the same time, it can ensure the consistent quality of printing and save input costs. Not only to do a good test, but also to do maintenance. Nip in the bud, and you'll be better at work.The use of pad printing machine must be checked regularly, first of all to ensure that the power supply is non-destructive and no leakage phenomenon to avoid safety hazards. Secondly, it is necessary to check the wear and tear of various parts such as oil and water separators, gas pipes and so on, and whether they work normally to avoid the failure of parts during work. The working air pressure should also be checked and maintained regularly, so as to ensure the stability of the printed pattern, ensure that the quality meets the requirements, and reduce the rework rate.

The working principle of screen printing machine.The full name of the Screen printing Machine is "screen Printer" (Screen Printer Machine), which is a device that leaks the screen printing ink to the printed surface according to the shape of the screen opening. It can be divided into vertical screen printing machine, inclined arm screen printing machine, rotary screen printing machine, four-column screen printing machine and automatic screen printing machine. Mainly used in the electronic processing industry, printed circuit board screen logo, instrument shell panel logo, circuit board processing process solder paste printing. Screen printing is the silk fabric, synthetic fiber fabric or metal wire mesh stretched on the screen frame, using hand-carved paint film or photochemical plate making method to produce screen printing plates. Modern screen printing technology is to use sensitive materials to make screen plates by photographic plate making (so that the screen holes on the graphic part of the screen plate are through holes, rather than the screen holes on the graphic part are blocked). When printing, the extrusion of the scraper makes the ink transfer to the substrate through the mesh of the graphic part, forming the same graphic as the original manuscript. Screen printing equipment is simple, easy to operate, simple printing, plate making and low cost, strong adaptability. Screen printing has a wide range of common prints: color oil paintings, posters, business cards, bound covers, commodity signs and printing and dyeing textiles.

Pad printing machine is mainly used for the production of screen printing products, in plastics, ceramics, toys have more applications. Pad printing machine also has a variety of types, so today's small series is mainly to analyze the precision of pad printing machine is not enough.1. Pad printing machine pad printing steel plate: when several color plates are placed in the wrong position, pad printing color accuracy decreases, or the pattern on the plate is not good, resulting in insufficient fineness.2. Glue head: the glue head is not installed in the central position; The size of the rubber head is different or the hardness of the rubber head is inconsistent; The pressure of the glue head on the steel plate or substrate is not uniform.3. Substrate: the substrate should have a certain degree of softness and hardness and the smoothness of its surface.4. Other aspects: positioning, fixture and workpiece fixing must be reliable.Pad printing machine is a professional printing equipment, there are many points of attention for the operation of pad printing machine, here, small series of pad printing machine operators fixed correct operation to explain.

Pad printing machine principleThe principle of pad printing machine is to first use the method of photographic plate making to print the required pattern, make the steel plate into a gravure plate and then transfer it to the printed material through a special silicone printing head, and according to the material of the product, the special ink can be modulated to ensure the quality. First, the design pattern is etched on the printing plate, the etching plate is coated with ink, and then most of the ink is transferred to the printed object through the silicone head.1. The ink is evenly covered on the steel plate by the brush;2, the excess ink will be scraped by the scraper steel knife;3. From the printing head down to the steel plate, the ink in the pattern is picked up;4, from the printing head shift down to the product will cover the pattern.How to use pad printing machine, manual pad printing machine use method
