What is the difference between pad printing and silk screen printing?

The principle of silk screen printing is transferred to the workpiece through the action of the glue head, similar to the seal in daily work, and the ink penetrates into the product from the mesh of the screen plate through the pressure of the rubber scraper, forming a pattern printing area The printing area of pad printing has a certain limit, at present, the largest printing surface in China can be 150 * 450mm, but it is not solid printing, but intermittent characters, solid printing, the maximum diameter is 300mm, but the cost of consumables (rubber head) will be very high The printing area is basically unlimited, the flat flat printing can reach 1500*2000mm, the cost of consumables (screen) is low, and the product shape can be reused There is no restriction on the shape, the plane, the curved surface, the wavy surface, as long as the rubber head deformation can reach the place can be printed The printing surface of the product is required to be flat, and the pure plane or regular curved surface printing quality is high.

Color: The pad printing machine can do up to 12 color registers in one machine, and the product is printed at one time, and the cost is low, which is suitable for the investment of the general factory The screen printing machine can also do multi-color overprinting, but the screen printing machine of multi-color overprinting is very expensive, not suitable for general factory investment, and the manual one-time multi-color overprinting occupies a large area and has many labor.

Features: pad printing of the ink layer is thinner, can be printed on any surface color, showing very good color expression and printing adaptability, commonly known as universal printing, in addition to water and air can not be printed, any object can be printed with pad printing The ink layer of silk screen printing is thick, the printed pattern has a strong three-dimensional sense, and the concave and convex sense can be touched by hand, which is suitable for the surface printing of high-end products, the color expression is very good, and the multi-color overprinting is more troublesome, and the surface requirements of the product are regular planes or curved surfaces, and there are certain limitations in the printing range. The principle of pad printing.

The principle of pad printing is to use the method of photographic plate making to make the pattern to be printed, and then make the steel plate into gravure and then transfer it to the printed material through a special silicone print head, and according to the different materials of the product, the special ink can be modulated to ensure the quality. The process of pad printing machine is divided into the following four points:

1.The ink is evenly covered on the stencil by a brush.

2.The excess ink is scraped off by a scraping steel knife.

3.The ink inside the pattern is lifted from the print head to the steel plate.

4.From the displacement of the print head to the product will be covered with the pattern.

Pad printing machine applicable industries: plastic industry, toy industry, glass industry, metal industry, electronics industry, sporting goods, stationery industry, optical industry, IC packaging industry, etc.

The screen printing machine is also the screen printing machine. In the printing industry, the probability of using screen printing machine printing is relatively high. Its working principle is a device that leaks ink to the surface of the substrate to be printed according to the shape of the screen opening that needs to be printed through the screen printing screen.

The biggest advantage of the screen printing machine is that the substrate can be varied, but it is more suitable for the printing of flat objects.

And the pad printing machine is more suitable for small area, irregular products.

These two machines are fast and efficient in monochrome printing. Of course, two-color and multi-color can also perform well. However, if the color is too complex, then it is not so good at it. Complex colors are more suitable for the use of hot stamping machines or thermal transfers, as well as more advanced printing techniques.

Technological differences. The production is driven by the pad printing machine, and the screen printing can be divided into manual and machine, and the use is different. The advantages also vary. Silk screen printing can almost be produced. Pad printing is mostly on the basis that the substrate is special-shaped, and the area that can be printed is not very large.

Silk screen printing is screen printing, generally manual scraping over the pattern on the silk screen, and the particles of the ink required are relatively small. But now there are also a lot of machine screen printing machines, can already print out the round products, pad printing has been printed with the machine, is the ink through the steel plate and then by the hanging knife to hang the ink on the steel plate back, the steel plate will have the pattern you want, and then by the glue head to move the ink on the pattern to your product.

Pad printing: the use of glue head as an intermediary, the steel plate on the first transfer to the workpiece, this printing process can achieve good printing effect on both regular and irregular surfaces, fast speed, high color resolution, low pressure (can be printed on eggs and cakes), low cost input;

Advantages: It can be applied to printing on non-standard workpieces (such as golf balls), the printing speed is fast, the resolution rate is high, especially multi-color printing, the cost is low, and the operation is simple;

Disadvantages: the ink layer is thin, if UV printing is required, it is difficult to choose ink, and it is not suitable for large-area printing;

Silk screen printing: also known as screen printing, is to print the first on the screen plate on the product through the squeegee pressure, this process is suitable for printing on the regular workpiece (plane, round surface, conical surface), and the printing ink layer is thicker than pad printing, and the three-dimensional sense is strong;

Advantages: thick ink layer, strong three-dimensional feeling, suitable for large-area printing, wide application, and various ink options;

Disadvantages: the traditional screen printing speed is slow, the cost of automatic drying color registration or monochrome screen printing machine occupies more, and the product should be regular;

1. Pad printing is a kind of silk screen printing, 2. Pad printing can print curved surfaces, of course, it can also print flat surfaces, and we generally say silk screen printing, which refers to flat screen printing.

Pad printing. Using the rubber head as an intermediary to transfer the first on the steel plate to the workpiece, this printing process can achieve good printing results on both regular and irregular surfaces, fast speed, high color resolution, low pressure (can be printed on eggs and cakes), low cost input;

Advantages: It can be applied to printing on non-standard workpieces (such as golf balls, the printing speed is very fast, the resolution rate is high, especially multi-color printing, the cost investment is low, and the operation is simple;

Disadvantages: the ink layer is thin, if UV printing is required, it is difficult to choose ink, and it is not suitable for large-area printing;

Silk hall front printing: also called screen printing.

It is printed on the product by the squeegee pressure, this process is suitable for printing rubber brushes (plane, round surface, conical surface) on the regular workpiece, and the printing ink layer is thicker than pad printing, and the three-dimensional sense is strong;

Advantages: thick ink layer, strong three-dimensional feeling, suitable for large-area printing, wide application, and various ink options;

Disadvantages: the traditional screen printing speed is slow, the cost of automatic drying color registration or monochrome screen printing machine occupies more, and the product should be regular;

Problem description: Is the Sibi State Seal the same as the Pad Print? If not, what's the difference?

Analysis: Silk screen printing: pad printing through screen printing (pattern on silk screen): transfer printing through rubber head. (Pattern rubber head).

Curved surfaces can be printed.

Generally speaking, the silk screen printing effect should be good, and the pad printing should be faster.

Supplement: The pad printing process completes the transfer of ink with the help of a pad printing head that can be deformed, and the surface of the pad printing head does not contain **; The first thing needed is to be dried and etched into a pad printing gravure, and then the ink is coated on the surface of the pad printing gravure, and the ink in the non-** area of the printing plate surface is scraped off with a hard spatula, and the ink at the pit of the printing plate is dipped in the rubber head and lifted, and moved to the surface of the substrate for embossing to complete the printing.

Screen printing can be done on a flat surface, or on a circular surface with little curvature.

The printing ink layer is thick, which can completely cover the background color

Large printing area

Silk screen printing is more suitable for expressing text and lines of bright monochrome color originals, and is also suitable for expressing contrast, clear layers of color originals Through the special effect of screen printing, the reproduction has rich expressiveness.

1. The difference between printing products: [click to get screen printing machine equipment for free**].

a；Silk screen Screen can be used to print large flat surfaces (e.g. large areas of glass). Silk screens can be printed circumferentially (e.g. cups), also known as roll printing. Silk screens should not be printed with fine fine text.

b；Pad printing can print products with irregular surfaces or products with stepped structures on the surface, but screen printing cannot. Pad printing can print fine small text, such as the small text that can be seen with a magnifying glass on the lens of a mobile phone.

2. Printing consumables:

a. Silk screen screen printing machine, screen plate, screen printing squeegee, screen printing ink, screen printing tooling, etc.

b. Pad printing Pad printing machine, pad printing steel plate (with thin steel sheet), pad printing rubber head, pad printing ink, pad printing squeegee or oil cup, etc.
