What is the difference between pad printing and spray painting? Which is printed out in bright color

The spraying is more vivid.

Spraying is more suitable for large areas or overall surface treatment.

Pad printing is more suitable for small area and local surface treatment.

And spray paint can't be multi-color or contrasting like pad printing.

Pad printing also cannot be treated as a full surface like spray paint.

And: the cost of painting is relatively high, and the cost of pad printing is low.

Pad printing is one of the special printing methods. It is capable of printing text, graphics and images on the surface of irregular shaped objects, and is now becoming an important type of special printing. For example, the text and patterns on the surface of mobile phones are printed in this way, and the surface printing of many electronic products such as computer keyboards, instruments, and meters is completed by pad printing.

Spray paint, a type of artificial paint, made with nitrocellulose, resin, pigments, solvents, etc. It is usually sprayed evenly on the surface of the object with a spray gun, which is resistant to water and oil, and dries quickly, and is used to paint automobiles, aircraft, wood, leather, etc. The substance is toxic and has a certain impact on the body, and different brands of spray paint have different toxicity due to different ingredient content.

Special attention should be paid to safety when using and avoiding inhalation and ** contact. The pad printing machine is mainly composed of a printing plate device (including an ink supply device), an ink scraper, a pad printing rubber head (generally a silicone material) and a printing table.

Personally, I feel that the spray paint color is more vivid.

It is not very obvious how much difference there is in the pattern, such as in terms of its use and particularity, it should be easier to distinguish:

1.The oil injection pattern can be larger than the pad printing pattern, generally speaking, the pad printing pattern is larger at 11cm*11cm, and the oil injection does not have this limitation;

2.Fuel injection can be sprayed on products with a large pattern amplitude, while pad printing is generally not more than 60 degrees, of course, there are other aspects that can be summed up some differences.

However, I personally recommend considering from the perspective of environmental protection and cost, and try to pad print as much as possible.

Differentiation:

1. Area, pad printing has area limitations, the pad printing glue head cannot come out very large, and there is no problem with oil injection;

2. Radian, in the same way, the deformation of the pad printing rubber head will be deformed if the printed pattern is printed on the product with too large arc;

3. The main point is that the pad printed pattern can have a gradient effect in the pattern, but the effect of oil injection will not;

4. The last point is a personal opinion, the pattern of the oil injection is much more beautiful than the pattern of the same kind of pad printing, the key is the brightness.

I don't know about pad printing, in silk screen printing and UV printing, when this happens, a layer of white ink will be applied under the color.

Some materials are relatively difficult to color, you can polish the surface, and make rough points will be better colored.

Sick plus just came out of the body.

All organic chemical coatings (including paints) have oxidation (aging) phenomena, and over time, their coating films will naturally crack in brittleness, reduce gloss, yellowing and fading. Therefore, its color is the most vivid after about 24-48 hours of film formation.

Silk screen printing: by screen printing (the pattern is on the silk screen) Pad printing: transfer printing through the rubber head.

patterned rubber head) can be printed on curved surfaces. Generally speaking, the silk screen printing effect should be good, and the pad printing should be fast Supplement: The pad printing process completes the transfer of ink with the help of the 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 used for flat surfaces, or arc surfaces with little curvature. The printing ink layer is thick, which can completely cover the background color Large printing area Screen printing is more suitable for expressing the text and lines of the monochrome set of color originals, and is also suitable for the expression of contrast, clear color originals Through the special effect of screen printing, the reproduction has rich expressiveness.

Silk screen printing is generally manual silk screen printing, while pad printing is printed by machine, but their results are the same, their biggest difference is that there is a big difference in efficiency and quality.

Willett automatic screen printing machine.

The first thing to do is to figure out how the two work in between. Silk screen printing is simply called leak printing, which is forced to leak ink from the mesh by scraping pressure. Use of stencils, squeegees.

The Willett coil screen printing machine transfers the pattern engraved on the steel plate to the workpiece through the action of the rubber head, similar to stamping. Use steel plates and rubber heads.

In general, the ink layer of silk screen printing is thicker than that of pad printing.

1.Principle.

Pad printing: The pattern engraved on the steel plate is transferred to the workpiece through the action of the glue head, similar to the stamp in daily work.

Silk screen printing: The ink is penetrated from the mesh of the screen to the product by the pressure of the squeegee to form a pattern.

2.Printing area.

Pad printing: There is a certain limit to the printing area of pad printing.

Pad printing: The printing area is basically unlimited, the cost of consumables (screens) is low, and it can be reused.

3.Product shape.

Pad printing: There is no restriction on the shape, flat surface, curved surface, wavy surface, as long as the deformation of the rubber head can reach the place can be printed.

Silk screen printing: The printing surface of the product requires a flat, pure flat or regular curved surface.

4.Color. Pad printing: The pad printing machine can do up to 12 color registers in one machine, and the product can be printed at one time, and the cost is low, which is suitable for the investment of general factories.

Silk screen printing: The screen printing machine can also do multi-color overprinting, but the screen printing machine with multi-color overprinting is very expensive and not suitable for general factory investment.

5.Peculiarity. Pad printing: The ink layer of pad printing is thin, and it can be printed on any surface, showing very good color expression and printing adaptability, commonly known as universal printing, except for water and air can not be printed, any object can be printed with pad printing.

Silk screen 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 overprint 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 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.

Pad printing is a kind of silk screen printing, pad printing can print curved surfaces, of course, it can also print flat surfaces, and we generally say silk screen printing, referring to flat screen printing. Pad printing is a corrosive pattern on the steel plate, and then transferred to the substrate through the rubber head, the advantages of pad printing, suitable for large and small products, as well as a variety of strange shaped special-shaped products, disadvantages, no feel, the ink layer is relatively thin, 2, silk screen printing is printed on the substrate through the screen pattern, the advantages of silk screen printing, there is a feel, and can be large plane silk screen printing, the disadvantages are not suitable for special-shaped products, the ink layer of the screen printing process is relatively thick. The two processes have their own merits.

The ink layer of pad printing is thinner, and it can be printed on any surface, showing very good color expression and printing adaptability, commonly known as universal printing, except for 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, with good color expression, multi-color overprinting is more troublesome, and the surface requirements of the product are regular plane or curved surface, and there are certain limitations in the printing range. The pad printing and silk screen printing of Zhuhai Qilang packaging materials can be processed.
