What are the types of printing processes

Question 1: What are the technical types of printing processes Printing types and characteristics

Printing methods have a variety of methods, different methods, the operation is different, printed into the effect is also different. Traditionally used printing methods can be divided into: letterpress,

lithographic, intaglio and aperture printing four categories.

Relief Printing

Where the printing surface is prominent, and the non-printed part is concave, known as letterpress printing, letterpress printing, including the live version and the rubber version of the two.

Letter press

Letterpress is from the early clay movable type and woodcut movable type and lead casting movable type development, extended to modern most of the lead typesetting-based, at the same time

This method of printing, because it is printed directly by the printing plate printed on paper, so it is a kind of direct printing.

The printing plate used in letterpress printing, in addition to the text part of the use of lead typesetting, other special fonts or patterns, pictures and so on, is the use of photographic

version of the method, made of zinc (commonly known as the electric version), and the recent development of more to the nylon offset version, improve the dot printing effect.

The general lithographic plate is flat, but there are some cases, the need to copy the flat printing plate into a curved lead plate, which can be mounted on a reel-type rotary

letterpress for a large number of printing, such as newspapers.

In addition to printing pictures of the text, lithography in addition to a number of accessories, but also can be printed on the surface of the text pattern of concave-convex printing can be cut printing surface (commonly

called beer samples) and printing for the tearing of the paper with the pinhole line and the addition of automatic transposition of the digital word, and so on.

Rubber gelatin printing (Flexgraphy)

Rubber gelatin printing and printing similar to lithography, the difference is that the plate is a piece of soft rubber, such as stamping like glue. The ink used is similar to gravure printing

and is highly volatile and thin, and is used to print adhesive paper and bags.

The method of plate making is divided into three steps: First, first make the graphic into a live version of the electric plate. Second, with bakelite similar to the hard glue heated pressure on the above

electroplate, printing hard block of the negative mold of the plate. Third, the same again in this negative mold with another soft rubber heating pressure on the negative mold, and the first step

in the same offset plate with the original electroplates.

Various types of adhesive paper, such as cellophane (Cellephane), P, V, C adhesive, polymerized fat adhesive paper (Polyester), acetate (Acetate), etc.,

Surface non-absorbent and permeable ink properties of the material can be printed on it. Suitable for printing plastic bags, hand pumps, the size of the plastic packaging. But this printing

method of printing fine points, lines are not as good as offset and offset lithography, so the picture should pay attention to emphasize the big effect.

Lithography (Planography)

Lithographic printing basic principles

Lithographic printing is the development of early lithography and named, early lithographic printing and its plate material using stone smoothing after the application, after the improvement for the metal

zinc plate or aluminum plate for the plate material, but the principle is unchanged.

Where the printing part and the non-printing part are not the difference between high and low, that is, the plane, the use of water and oil do not mix the principle of the printing part to maintain

a layer of oil film rich in grease, while the non-printing part of the plate can absorb the appropriate amount of water, imagine that in the ink on the plate after the printing part of the

will be excluded from the water and absorbed the ink, and the non-printing part of the water absorbed to form an ink-resistant effect. The non-printed part of the ink is absorbed moisture and the formation of ink resistance, the use of this method of printing method, it is called

"lithographic printing".

After the development of lithography from the early stone printing, because of its plate making and printing has its unique personality, at the same time in the work is also extremely simple, and low cost

cheap, so in recent times by the experts continue to study and improve, and become today's printing on the most used methods.

Lithographic method

Lithographic method is developed from the early lithographic transfer method, and depicted on the transfer paper and then fell on the plate to become the reverse pattern, and then printed

on the paper for the positive pattern. Due to the pressure of this method in printing, so that the original is a flat version of the plate (i.e., printing and non-printing part of the

part are flat), after bearing the pressure, so that accounted for the ink on the plate for the diffusion of the expansion, resulting in the painting of the line of bad phenomena, and therefore

later improved known as 〖Orchard Printing method〗 (offset Printing) of the printing method is to make the plate into a positive line. The printing method is to make the layout into a positive pattern, printing is transferred to the rubber

tube for the reverse pattern, and then printed by the reverse pattern to the paper for the positive pattern, which can improve the flexibility of the printing pressure.

Question 3: What are the processes for printing? Inkjet printing

Inkjet printing is a highly efficient way of special printing, it can be applied to the packaging industry production line, quickly print the production date, batch number and bar code and other content . It is a non-contact, no pressure, no printing plate printing. The information stored in the electronic computer, input inkjet printer can be printed.

Digital technology continues to progress, inkjet printing has also developed very quickly, some technical problems have been perfectly solved, which makes the quality of inkjet printing products have made a qualitative leap. Adopting the latest JDF production standards, inkjet printing equipment can also be easily integrated into the digital production process of the entire printing plant, thus achieving better equipment control and higher productivity.

Anti-counterfeit printing

It can be said that in the field of packaging printing, anti-counterfeit printing has a crucial role. If the general products need a significant product identification, then many high-grade products have to need a set of perfect anti-counterfeiting system. Anti-counterfeiting printing is a comprehensive anti-counterfeiting technology, which is a branch of special printing. It refers to the use of printing means to prevent imitation, reproduction or forgery without the permission of the ownership.

Anti-counterfeiting printing is widely used in the printing of packaging and decorative products, and with the increasing awareness of people's brands and the increase in the protection of intellectual property rights, I believe that anti-counterfeiting printing will have a great market prospect.

Label Printing

Self-adhesive labels are commonly used in the packaging and decoration industry. In China, the current trademark printing is mainly self-adhesive letterpress-based, with the diversification of trademarks, high-grade, other printing methods have gradually joined.

Metal products

Metal printing belongs to a special printing method of the bearing material. Due to its high cost, it is generally used in the packaging of luxury goods, so its profit is also higher. At present, the metal printing substrate materials in the gradual increase, new materials continue to emerge. Regardless of which material is used, its printing process is different from paper printing, the main domestic use of offset printing, transfer printing, screen printing and flexographic printing methods.

Paper Packaging Printing

This area accounts for most of the share of packaging and decorative printing, but also the application of special printing technology is less in the field, but in this area we can also use innovative ideas to create more value. Due to the development of earlier, carton printing and cardboard printing technology has been more mature, most of the printing houses have the production capacity of such products. Packaging printed on the decorative pattern, pattern or text, in order to make the product more attractive or more descriptive. Yau Chi Packaging Printing provides

Question 4: What are the printing processes General printing processes are:

1 hot stamping: the scientific name is called thermal transfer printing, referred to as thermal transfer printing, commonly known as hot stamping, hot stamping, hot stamping silver. Relatively there is a cold transfer printing.

2 UV: that is, ultraviolet light, UV is the abbreviation, "UV transparent oil" is the full name, is to rely on ultraviolet radiation in order to dry the curing ink. UV is usually silk screen printing process, and now there are also offset UV.

3 embossing, embossing: the scientific name of the embossing, the press to make the printed object to produce a local change in the formation of patterns, is a metal plate printing process. The formation of patterns of the process, is a metal plate corrosion after becoming a pressure plate and the bottom of the two pieces of the press fit. Divided into cheap ordinary corrosion version and expensive laser engraving version of two kinds.

4 beer: Guangdong pronunciation of "turtle", is the meaning of die-cutting.

5 Jin Cong: that is, a layer of glue on the paper first, and then sprinkle gold dust on the glue.

6 YO: is a spring-like object, plastic mostly, generally used in calendars and notebooks on the spine, turn the pages connected.

7 overglued: to the printed paper pressed a layer of transparent plastic film, crystal film, light film and matte film, many places called some different, not environmentally friendly.

8 pinhole: also known as the needle line, dental floss, that is, to the paper pressed out of a half-connected line, usually appear in the package opening.

9 Perforation: is required by the size of a piece of paper or N paper to get a hole out, there are specialized punching machines.

10 flocking: is to give the paper on the brush layer of glue, and then paste a layer of similar fluffy material, so that the paper looks and feels a little bit of velvet feeling.

Question 5: What are the printing process, I hope to be able to introduce the Above these are the post-press process, so many questions, only 5 points, too little right?

1 hot stamping: the scientific name is called thermal pressure transfer printing, referred to as thermal transfer printing, commonly known as hot stamping, hot stamping silver. There is a relative cold transfer printing.

2 UV: that is, ultraviolet, UV is the abbreviation, "UV transparent oil" is the full name, is to rely on ultraviolet radiation in order to dry the curing ink. UV is usually silk screen printing process, and now there are also offset UV.

3 bumping, embossing: the scientific name of the embossing, the press to make the printed object to produce a local change in the formation of patterns process, is a metal plate. Formation of patterns of the process, is a metal plate corrosion after becoming a pressure plate and the bottom of the two pieces of the press fit. Divided into cheap ordinary corrosion version and expensive laser engraving version of two kinds.

8 pinhole: also known as the needle line, dental floss, that is, to the paper pressed out of a half-connected line, usually found in the package opening.

9 Perforation: It is required by the size of a piece of paper or N paper to get a hole out, there are specialized punching machines.

10 flocking: it is to give the paper on the brush layer of glue, and then paste a layer of similar fluffy material, so that the paper looks and feels a little bit of velvet feeling.

Question 6: What are the main 3D printing processes 3D printing according to the material and molding method 3D has many different types:

LOM. This is coated with hot melt adhesive paper layers, laser cut contours to form the form;

SLA. The use of liquid photosensitive resins in the ultraviolet light irradiation can be quickly cured into a solid to form the method;

SLS. laser selective sintering molding (raw materials can be plastic powder, ceramic powder, metal powder, etc.);

FDM, the use of plastic filament melting and then printed layer by layer molding;

3DP. raw materials are powder plus resin, can print color.

Question 8: What kinds of printing are there? > Question 8: What are the types of printing? Usually can be divided into letterpress, intaglio, lithographic, perforated printing 4 categories. Letterpress printing plate used in the graphic part of the bulge, which includes engraving, movable type, lead, copper and zinc plate, photopolymer resin plate and flexographic printing. Since the flexographic printing since the 1980s there has been greater development of its printer structure and printing substrates and general letterpress is different, so some countries to flexographic printing as a separate type of printing. Gravure printing plate of the graphic part of the concave, and is divided into engraved gravure, photogravure and electronic engraved gravure 3 categories. Lithographic printing plate of the graphic part and the non-graphic part of the basic in the same plane, usually refers to offset printing, but in fact, lithography (has been basically eliminated) and Cora transmutation∷ (as a unique process to preserve) are also lithographic category. Perforated printing is mainly screen printing, that is, screen made of graphic part of the ink can pass through the non-graphic part of the ink impermeable plate for printing. Transcription plate printing is also hole printing.

According to the printing process, the above four types of printing and direct printing and indirect printing of different. Plate ink first transferred to the blanket cylinder, and then by the blanket cylinder will be transferred to the paper offset printing is indirect printing, the rest of the various printing methods (including lithography in lithography) are direct printing. The direct printing version of the graphic for the reverse image, indirect printing version of the graphic for the positive image.

The above printing methods, although the plate material and printing process is different, but when printing, are paper (or other substrate) and plate contact, and apply a certain amount of pressure, is a contact imprinting printing. With the development of computer technology and equipment, there are laser printing and inkjet printing, such as the emergence of such new methods in the printing and no embossing action, known as non-contact or unpressurized printing.

Question 9: What are the materials of printing paper 1. Letterpress paper

Letterpress paper is for letterpress printing books, magazines, the main paper. Letterpress paper can be divided into four levels: No. 1, No. 2, No. 3 and No. 4 according to the different distribution ratios of paper materials. The number of paper represents the degree of goodness of the paper, and the larger the number, the worse the paper quality. Letterpress paper is mainly used for letterpress printing machines. The characteristics of this paper and newsprint similar, but not exactly the same. As the ratio of pulp material and pulp knockdown are better than newsprint, letterpress paper fiber tissue is more uniform, while the gap between the fibers and a certain amount of filler and glue filled, and also after bleaching, which formed the paper on the printing of the adaptability. Slightly different from newsprint, its ink absorption is not as good as newsprint, but it has the characteristics of uniform ink absorption; water resistance and paper whiteness are better than newsprint. Letterpress paper has a uniform texture, lint-free, slightly elastic, opaque, slightly water resistance, a certain degree of mechanical strength and other characteristics.

Weight: 49～60)±2g/m2.

Flatbed paper specifications: 787×l092mm, 850×ll68mm, 880xl230mm; as well as some special size specifications of the paper.

Specifications of rolled paper: width 787 mm, 1092 mm, 1575 mm, length of about 60m ~ 80oo meters.

2. Newsprint

Newsprint, also known as white paper, is the main paper for newspapers and books. Newsprint is characterized by: soft paper, rich in good elasticity; good ink-absorbing properties, which ensures that the ink faster fixation in the paper; paper after calendaring on both sides of the smooth, not hairy, so that both sides of the prints are clearer and fuller; a certain degree of mechanical strength; opaque performance; suitable for high-speed rotary printing machine. This kind of paper is produced from mechanical wood pulp (or other chemical pulp) and contains a large amount of lignin and other impurities. It is not suitable for long-term storage. When stored for too long, the paper will become yellow and brittle, with poor water resistance, and is not suitable for writing, etc. Must use printing newspaper ink or book ink, ink viscosity should not be too high, lithographic printing must be strictly controlled layout moisture.

Weight: 49 to 52 ) ± 2 g / m 2

Flatbed paper specifications: 787 x 1092 mm, 850x ll68 mm, 880x l230 mm.

Roll paper specifications: width 787 mm, 1092 mm, 1575 mm; length of about 6000 to 8000 meters.

3. Offset paper

Offset paper is mainly for lithographic (offset) presses or other printing presses to print higher-level color prints, such as color pictorials, albums, posters, color printing of trademarks and some high-level books, as well as book covers, illustrations and so on. Offset paper according to the ratio of pulp material is divided into three kinds of special, No. 1 and No. 2, single-sided and double-sided, with super calendering and ordinary calendering two grades. Offset paper expansion and contraction of small, uniform absorption of ink, smoothness, texture tight opaque, whiteness is good. Strong water resistance. Should be used in conjunctive offset printing ink and better quality lead printing ink. The viscosity of the ink should not be too high, otherwise there will be de-powdering, pulling phenomenon. It is also necessary to prevent the back from sticking dirty, generally using anti-dirty agent, spray powder or lined paper.

Weight: 50, 60, 70, 80, 90, 100, 120, 150, 180 g/m2.

Flatbed paper specifications: 787 × l092 mm; 850 × 1168 mm.

Roll paper specifications: 787 mm, 1092 mm, 850 mm.

4, coated paper

Copperplate paper, also known as printing coating paper, this paper is coated with a layer of white pulp on the original paper, after pressing. Light and made. Paper surface smooth, high whiteness, uniform distribution of paper fibers, uniform thickness, small expansion,, good elasticity and strong water resistance and tensile properties, the ink absorption and reception state is very good. Coated paper is mainly used for printing albums, covers, postcards, exquisite product samples and colorful trademarks. Copperplate paper printing pressure should not be too large, to use offset resin-based ink and glossy ink. To prevent the back and sticky dirty, can be used to add anti-dirty agent, spray powder and other methods.

Question 10: What are the processes of printing logos 1, stickers - sticker-style

2, pad printing - directly on the product to do, regular, irregular can be printed, fast, but not suitable for printing a large area, the ink layer is thin

3, silk screen - directly on the product to do, suitable for the regular shape, the ink layer is thick, the three-dimensional sense of strong. Slightly slower, irregular products are not good print

4, transfer printing --- divided into thermal transfer and water transfer, directly on the product to do, pattern resolution is very high, the surface is bright, but the cost is also high

5, color spraying --- called a lot of digital printing, digital color printing, universal printing, lithographic printing is said to say that this, without making a plate directly to the output, the pattern is clear, bright, high-cost, can only be done on a flat surface.

Probably these, not comprehensive words also hope to learn from each other.
