What is the difference between uv printing, inkjet printing, silk screen printing, color printing, o

UV flatbed printers are not limited by any material, and can print on glass, ceramic, wood, crystal, PVC, ABS, acrylic, metal, plastic, stone, leather, etc. Whether it is a simple block color pattern, a full-color pattern or a pattern with a transition color, it can be printed at one time, without plate making, no need to expose the plate and repeat the color, the color is beautiful and rich, the effect is realistic, the image is waterproof, sunscreen, wear-resistant, non-fading, simple and convenient operation, fast printing image, fully meet the needs of the market. The input cost is low, and the application field is very wide, which can be used in the glass technology industry, glass sliding door industry, screen printing industry, gift processing industry, sign identification industry, decoration and decoration industry.

UV printing, inkjet printing, silk screen printing, color printing, offset printing, these are several different printing processes.

To learn more about the differences, search them separately and look at the encyclopedia introduction, which is more detailed.

There are many processes in the printing field, not to mention the good, that bad, the key is to consider the characteristics of the material, the actual production cost consideration.

What is the difference between UV printer printing and silk screen printing? The former can be printed directly with a good pattern, and the latter also needs to be plate-making, ferlin, color and other processes.

The difference between UV printer and silk screen printing is mainly the printing process:

1. UV printers use UV ink, and the curing principle is LED ultraviolet light curing principle; Achieve the effect of hitting and drying;

2. Silk screen printing is to use the screen board to squeeze the content to be printed to adhere the ink to the product.

What is the difference between silk screen printing and printing on UV flatbed printers.

1. Cost comparison.

Traditional screen printing requires film plate making, and its own printing cost is more expensive, and the screen printing points can not be eliminated, and mass production is also needed to reduce costs, and it is impossible to achieve the printing of small batches or individual products.

UV lithography does not need such a complex typesetting design, only needs a simple ** processing, calculate the relevant values and directly use the software to operate, and can print a product, inkjet printer, not limited to the minimum number, from some points of view also greatly saves time and cost.

2. Process comparison.

The screen printing process is more complex, based on the original, according to different printing materials to select plate-making and printing processes, there are many specific process types, different printer materials have different processes, the overall operation is quite troublesome.

For customers who have just come into contact with UV flatbed printers, the most headache is to face a variety of choice problems, what is the difference between screen printing and UV flatbed printing? Screen printing is relatively more traditional and more sophisticated.

There are three main types of UV printers and silk screen printing:

1. In principle: UV printer uses piezoelectric inkjet printing, and silk screen printing uses contact scraper printing;

2. Imaging: the digital color printing imaging principle adopted by UV printers, and the plate-making and film color matching processes used in silk screen printing;

3. Curing: UV printer adopts ultraviolet light curing pattern, and silk screen printing adopts high temperature drying, which is heavily polluted.

1. The types of colors of screen printing are relatively few, because screen printing glass can only screen print one color at a time. UV printing can be printed at one time, no need to make another stencil, only need to draw a computer drawing.

2. From the perspective of printing principle: UV identification and sign printer adopts piezoelectric inkjet printing, and screen printing adopts contact printing.

3. From the point of view of pollution degree: UV logo and sign printer belongs to environmentally friendly green printing, and screen printing belongs to high-pollution printing;

The former is the principle of inkjet printing, and the latter is the color of plate-making film.

In principle: UV printers use piezoelectric inkjet printing, and silk screen printing uses contact scraper printing;

Offset printing is what we often call offset printing, and it is also a kind of lithographic printing, which is very simple to say that offset printing is to pass the printing method on the printing plate to the substrate with the help of rubber (blanket), which is also the existence of blanket, which is named after this printing method. Blanket plays an irreplaceable role in printing, such as: it can make up for the unevenness of the surface of the substrate, make the ink fully transferred, it can reduce the transfer of water on the printing plate (see the role of water in printing) to the substrate and so on.

The above is only a general concept, we now usually talk about offset printing may be narrower, that is, there are three cylinders (printing plate, blanket, embossing) lithography printing method, in the south of our country this printing method is called offset printing.

UV printing is a printing process that dries and cures inks by ultraviolet light, which requires an ink containing photosensitizer to be matched with a UV curing lamp. The application of UV printing is one of the most important contents of the printing industry. UV ink has covered offset printing, silk screen, inkjet, pad printing and other fields, the traditional printing industry refers to the UV is the printing effect process, that is, on a print you want to print the pattern you want to wrap a layer of varnish (there are bright, matte, inlaid crystals, glitter powder, etc.), mainly to increase the brightness and artistic effect of the product, protect the surface of the product, its high hardness, corrosion and friction resistance, not easy to scratch, etc., some laminating products are now changed to UV, can meet the requirements of environmental protection, but UV products are not easy to bond, Some can only be solved with local UV or sanding.

The use of UV printers is UV printing, and the use of UV printers can print the desired pattern on any plane of material. And the UV printer can consider the Toshiba UV printer, which uses the Toshiba printhead. The ink dot is 5PL, the printing speed is 2 times faster than Epson's, the accuracy is higher than that of Ricoh G5, and the service life is 24 months and 36 months.

There is also a 2-year warranty.

The difference between UV printing and transfer printing and silk screen printing:

UV printing, is a computer good pattern direct printing;

Transfer printing is printed on the transfer sticker, and then pasted on the material;

Silk screen printing is a process that requires plate-making film color registration.

Silk screen. What is Silk Screen? Silk screen printing is a printing method that uses pressure to transfer ink to the substrate through the holes of the stencil.

The process principle of silk screen printing: pre-made plates, mainly paper film plates or other plates, make holes on the plate base to pass through the ink; Then, through the squeegee extrusion, that is, pressure, the ink on the plate is transferred to the product through the mesh to form a pattern.

Silk screen printing is suitable for printing paper, plastic, wood products, metal, glass, ceramics, cotton or chemical fiber and other products. Silk screen printing has no requirements for the smoothness of the product, is suitable for a variety of materials, and has a wide range of adaptability.

Thermal transfer. Definition: Thermal transfer is an emerging printing method that transfers the pattern on the transfer film to the surface of the substrate by heating and pressurizing.

Process: Thermal transfer printing is to make plates first, then make thermal transfer films, and finally print the patterns on the film onto the products. It acts through the medium of the membrane.

Thermal transfer is suitable for transfer on smooth flat or regular surface surfaces of plastics, metals, wood, ceramics and other materials such as ABS, PC, PP, PP, EVA, PVC, etc.

Products suitable for thermal transfer are:

1. Daily necessities, common ones include cups, slippers, kettles, buckets, floor mats, and chopsticks.

2. Stationery, such as pens, stationery boxes, pen holders.

3. Toys are mainly printed on the plane and curved surface of the toy's logo and pattern.

4. Gifts, such as cups, straps, hand straps, and other decorations.

5. Cosmetics, such as makeup boxes, shampoos, shower gels.

6. Electronic products, such as mobile hard disks, chassis, mobile phone cases, rice cookers, etc.

7. Building materials, such as stainless steel, metal strips, metal plates, wood boards and other products.

UV printing. Multi-color printing is formed at one time, without sleeve, and the printed pattern is exquisite and vivid, and the color gradient effect is good. ABS, PC, PP, PP, EVA, PVC and other materials such as plastic, metal, wood, ceramic, glass, crystal, etc.

As an emerging technology, the first aspect is the high point, but the added value of the products it brings is also high. It has obvious advantages in printing effect and production efficiency. Therefore, there is a lot of potential and market in its application field.

To sum up, all kinds of printing in its field of application have certain advantages, the choice of what kind of printing should first be based on the characteristics of the product material, surface, etc., to see which printing method the product is suitable for, and then for the cost, pattern effect, pattern adhesion, whether to export or to be certified and other factors, choose the right way.

UV screen printing ink is a kind of screen printing ink, which generally refers to the ink cured and dried by ultraviolet light, which is different from natural drying, heating and drying curing. It has the characteristics of fast curing and small color change.

According to the characteristics of ink, it can be divided into fluorescent ink, bright ink, fast-fixing ink, magnetic ink, conductive ink, fragrance ink, ultraviolet drying ink, sublimation ink, transfer ink, etc.

Distinguish the types according to the state of the ink; Colloidal inks, such as water-based inks, oil-based inks, resin inks, starch pastes, etc. Solid inks, such as toner for electrostatic screen printing.

According to the types of substrates: Paper inks: oil-based inks, water-based inks, high-gloss inks, semi-glossy inks, volatile drying inks, naturally drying inks, coating paper inks, plastic synthetic paper inks, cardboard carton inks.

Ink for fabrics: water-based inks, oil-based inks, emulsion-based inks, etc.

Inks for wood: water-based inks, oil-based inks.

Metal inks: special inks for different metals such as aluminum, iron, copper, stainless steel, etc.

Leather inks: special inks for printing leather.

Ink for glass pottery: ink for glass instruments, glass crafts, and ceramic utensils.

Inks for plastics: inks for polyvinyl chloride, inks for styrene, inks for polyethylene, inks for propylene, etc.

Inks for printed circuit boards: conductive inks, corrosion-resistant inks, electroplating-resistant and fluorine-resistant and alkali-resistant inks.

1) Classification according to substrates.

According to the chemical name of the substrate, it can be divided into: polyethylene, polypropylene (non-polar) ink. Polyvinyl chloride, polystyrene, ABS polycarbonate (polar) inks. According to the form of the substrate, it can be divided into soft plastic ink and hard plastic ink.

2) Classified according to the drying method.

There are volatile drying inks, ultraviolet curing inks, and oxidation drying inks.

Volatile drying ink: It is one of the most used inks in screen printing. The composition of the ink film is mainly polymer substances, and the solvent volatilizes after printing, and the polymer substances form the ink film. This volatile drying process is reversible, i.e. the dried ink film can be redissolved using a solvent.

After the ink is transferred to the substrate, there will be a solvent ink film, and the volatilization of the solvent will occur first. The solvent in the ink diffuses in the atmosphere due to the action of vapor pressure, forming a liquid film on the surface of the ink film, and then volatilizing through the liquid film. In this drying process, the internal drying is generally slow, and sometimes it is necessary to blow the air to speed up the drying process.

Volatile inks, easy to use, generally dry quickly, so they are widely used.

Ultraviolet light curing inks (UV inks): Ultraviolet inks can produce a photochemical reaction, which can be completely cured in a few seconds, and are increasingly used in plastic printing. The main components of ink are photopolymeric resins, initiators, pigments and additives, and in principle, no organic solvents are used.

Oxygen mold deification dry ink: the ink contains a polymer with a small molecular weight, which is oxidized in the air to form a polymer film through the chemical reaction of heat, light or reactive substances. After this ink is printed on the surface of the substrate, it generally needs to be heated to promote hardening.
