Printing process:

1, pre-press: refers to the work of the pre-printing, generally refers to photography, design, production, typesetting, output film proofing and so on.

2, printing: refers to the work of the middle of printing, the process of printing the finished product through the printing press.

3, after printing: refers to the printing of the later work, generally refers to the post-processing of printed materials, including gluing (laminating), UV, oil, beer, hot stamping, embossing, laminating, bookbinding, cutting, etc., mostly used in promotional and packaging printing.

Printing process:

1, relief printing

Relief printing is the printed materials after pressure processing so that they can be similar to the original, the general production of objects are oil paintings and so on. When the printing is completed, the print is attached to the top of the film, and then the pre-made platen (i.e., from the original painting by the photographic plate from the intaglio plate) in the print on the press work, can be made and the same as the original painting of the beautiful replicas.

2, hot stamping silver foil

In the book cover or board or plastic surface and so on often see the gold font or pattern, its performance is the need for hot stamping patterns or text made of convex type version of the heating, and then in the printed matter placed on top of the required color of the aluminum foil paper, pressurization of the aluminum foil will fall to the printed matter, the effect is excellent, and at the same time to make its aluminum foil closely connected to the printed matter, and never fade. The color will never fade.

3, magnetic printing

Magnetic printing is used in most of the securities of the check for more, so as not to be subject to the role of counterfeiting, magnetic printing is known as the MICR. its main purpose is to print the use of numbers and symbols from 0-9, etc., in the lower part of the check to the magnet powder mixed into the ink to print the numbers or symbols.

4, concave and convex embossing

The use of pressure to make the paper to produce the phenomenon of convexity, of course, this is the use of the paper's elasticity function and the feeling produced. Concave and convex models are necessary, the general method is to place the convex model to care about the table fixed, and then slightly heated, the concave model from the top to the bottom of the pressure, then the paper will produce the shape of the concave-convex.

5, floating printing (letterpress printing)

After the printing of ordinary printed matter, the use of resin powder (for the current use of rosin powder in Hong Kong and so on) spread on the ink is not yet dry, then the powder will melt in the ink, and then heated to make the printing part of the bulge. Floating printing powder used in bright, glossy, non-glossy, gold, silver, fluorescent color, and so on.

Search Encyclopedia - Printing processes and crafts content is specific only to this customer, if he does not want, no one else has no use. Printing classification: 1, offset printing: commonly known as color printing, with the film through the tanning machine in the pre-coated photopolymer plate (PS plate), and then printed on paper with an offset printing machine, the general number of lines in the screen 175 lines / square inches, 175L / inch; offset printing machine has a single-color machine, two-color machine, four-color machine, five-color machine, etc.; specifications have a large full-size sheet of the machine, full-opening machine, folio machine, four-opening machine, eight-opening machine, etc. 2, gravure printing: generally Plastic printing, or web printing, printing a large number of bags or cigarette labels, magazines, etc., to the electro-engraving cylinder version of the main. 3, silkscreen: general printing of thicker patterns, printing materials such as cloth, plastic, paper, cardboard board, etc., the printing plate is based on the mesh frame line, the ordinary general 80 ~ 100 lines, we contact for paper, such as printing UV oil, to do the effect of abrasive sand, local UV varnishing and so on. 4, flexo printing, watermarking is used to paste the film in the resin version, rubber version of the photographic corrosion or engraving printing patterns for printing. (In addition, hot metal letterpress, to first out of the negative film to do corrosion of the metal plate.) 5, offset screen and dot: generally 175 lines per inch for the majority, more commonly used in coated paper albums and other advertising printing, white paper or rougher surface of the paper should be used 150 lines; high-grade albums have 200 lines, generally 200 lines of the printing press requirements are very flat, out of the film is no problem, the key to the printing. Printing estimate (offset printing): First of all, to understand the customer's intention, the customer's company, address, telephone, contact person. Then, ask if you want to design and produce, or as long as the film, proofing. Important must ask the specifications, the number of 1, specifications, size, number of open, P number. 2, the number of printing. 3, paper: coated paper, matte powdered paper, white board paper, offset paper, white cardboard, self-adhesive paper, carbonless copy paper, special paper. 4, color, number of colors: CMYK four-color, gold, silver, spot-color. 5, post-processing process: folding, compound film (glossy film, matte film), hot stamping (hot gold area, hot green gold), creasing molding Or red gold), creasing die-cutting box (where more than 200g of paper should be creased, cartons to do die-cutting version of die-cutting), as well as gluing this, gluing bags, gluing boxes, laminating, over the varnish, buffing, over UV, laminating E-watt, etc.; bookbinding (horseback riding, flat-binding, wireless glued binding, wire binding, hardcover, YO ring binding, etc.); packaging and packing for delivery. Specific valuation steps are edition, paper, printing, after the process, tax management fee five parts: First, plate: 1, design and production, to 16 open per P, 1P150 yuan or so (including out of the film) 2, has done a good job of the document, only out of the film and proofing is generally calculated according to the 50 yuan per P. 3, pay attention to the specifications of the size of the bleed and the bite of the location to be left. Calculate the number of openings in general to 118 * 88cm, positive degree to 108 * 78cm calculation, the actual length of the finished product in addition to the length, width in addition to width, and then multiply the length by the width is equal to the number of openings, if it is a box to unfold to the size of the specifications of the number of openings on the valuation is very important. 4, spelling large version, the sun version of 60 yuan per color, generally calculated by the folio version, if it is a 16 open that is, 8 P counting a version. Second, the paper: generally what we call P is a side, 2P is a, and pay attention to picture books and other books are even P binding, so the general book cover is 4 P, if it is 16 open book cover back cover is a 8 open. Paper is generally divided into coated paper (matte powder paper), whiteboard paper, offset paper, etc.; we have already said, we are now the most commonly used coated paper (matte powder paper), whiteboard paper, offset paper, the three kinds of paper as an example, coated paper prices are currently temporarily calculated at 8,500 yuan per ton, whiteboard paper 5,500 yuan per ton, offset paper 6,500 yuan per ton, and then to the price of the ton ÷ different grams of each ton of paper order order price specific to see the paper g Number of tons / order conversion table. Calculation of the price of paper is generally: P number ÷ 2 * quantity * 1.1 (10% consumption) ÷ open number ÷ 500 orders, if the number of consumption of less than 50 sheets of each color according to the starting number of 50 sheets, and then the number of orders * order price to arrive at the price of paper. Consumption is generally 10% of the number of calculations, as long as 5% of the consumption of large single, large single generally refers to more than 50,000 sheets of 16 open. Traditional printing house is generally 3-5 ‰ per color consumption, if the double-sided 8-color is also about 4%. Usually the outer cover and inner pages of different paper, should be counted separately, and some have title page paper, lining paper sulfuric acid paper, etc. should also be counted separately. Then add the price of various paper is equal to the total price of paper. Third, the printer: printing process price with the number of paper orders * number of printing colors * processing color order price (fine prints are generally 50 yuan per color order), gold and silver spot colors and large areas of the full version of the 1-color by 2-color calculation. Starting price: the general folio starting price is 1,000 yuan, that is, after the above formula for each set of plate less than 1,000 yuan of printing costs calculated in accordance with the 1,000 yuan; monochrome machine is generally 30
