How to use a digital printing machine? Digital printing knowledge

There is a common problem for many customers with printing needs. They have printing needs, but they are not sure how to calculate the printing cost. The following is how to use the digital printing machine that I have compiled for you. Necessary knowledge of digital printing, I hope I can help you. Friends who find it useful can share it with more people!

1 specification number

The following is generally based on color printing (offset printing). First, we must know the specifications. Normal flat paper specifications are divided into generous and correct.

The full-page size of Dafang: 2975 px * 2225 px(47 inches *35 inches). Cutting into two pages is called folio, cutting into four pages is called quarto, cutting into eight pages is called octo (A3) and cutting into 16 pages is called 16 pages (A4).

The full size of orthographic paper is: 2700 px * 1950 px(43 inches *3 1 inch), and the same two sheets are orthographic, and so on.

Generally, it is necessary to set aside the bite of 25px machine paper and the 12.5px crosshairs on both sides for color matching.

Of course, it is mainly made of paper, so it can also be converted into square meters.

Paper is generally divided into offset paper, such as ordinary copy paper and writing paper; Coated paper, matte paper and cards with a thickness of more than 200 grams, such as copper cards, are mostly used in picture books and advertising color pages; Whiteboard paper and white cardboard are mostly used for carton packaging boxes; There are carbon copy paper, self-adhesive paper, sulfuric acid paper, specialty paper, carton paper, core paper, kraft paper, etc. The thickness of paper is generally calculated in grams. Generally speaking,157g coated paper means that the thickness of coated paper is157g per square meter. The greater the grams, the thicker the paper. In printing, it is customary to call 500 pieces of paper 1 ream. Paper is priced by tons, and the paper with different gram thickness has different orders. There are tables for reference.

2 paper printing

For four-color printing, the quality generally depends on whether there is registration, whether the printing dot is firm and clear, whether the layout paper is dirty and scratched, whether the trimming line is printed, whether the text is broken and whether the color is uniform. If there are proofs, please check them. Printing processing fee is usually calculated according to color sequence, that is, printing one color per ream of paper is called 1 color sequence.

3 Post-press and others

Post-press processing procedures include covering light film, covering dumb film, bronzing, oiling, UV exposure, folding, horse-riding binding, sewing and binding, indentation die cutting, fine tile E corrugation, etc. And packaging, delivery, collection and so on. Generally speaking, when you sign a contract, you must pay in advance. Usually, you must pay 50% of the fee in advance, because the printed content is specific and only belongs to the customer. He doesn't want it, and others are useless.

Printing classification

1 offset printing

Usually called color printing, the film is dried on a precoated photosensitive plate (ps plate) by a printer, and then printed on paper by an offset press. General screen lines are 175 lines/square inch and 175 l/ inch; Offset printing machines include monochrome machines, two-color machines, four-color machines and five-color machines. Specifications include full card machine, full boot machine, double boot machine, four boot machine and eight boot machine.

3 screen printing

Generally speaking, rough patterns are printed. Printing materials include cloth, plastic, paper, cardboard and so on. Printing plate is mainly based on the number of screen lines, and the number of ordinary lines is generally 80~ 100. We contact the paper, such as printing UV oil, sanding effect and local UV glazing.

4 Flexo printing, watermarking

It is printed by pasting film on resin plate and rubber plate, photosensitive corrosion or engraving printing patterns. (In addition, for hot metal embossing, the negative should be produced first to corrode the metal plate. )

5 offset lines and dots

Generally, it is 175 line per inch, which is commonly used in the advertising and printing of coated paper picture books. The 150 line should be used for white board paper or rough paper; Some advanced picture books use 200 lines. Generally, a 200-line printing machine is required to be flat and there is no problem in drawing. The key is printing.

First of all, we should know the customer's intention, customer's company, address, telephone number and contact person.

state of play

1, digital printing machine-developed from copier technology and digital technology.

(1) Typical representatives: Toshiba, Konica, Ricoh, Canon, Xerox and Ossie. This kind of equipment generally includes three parts: scanning part, laser printing part and folding and binding part. It has comprehensive functions and can be used for scanning, copying, printing and digital publishing.

This equipment belongs to a multifunctional digital printing system, which is a kind of digital printing. It has changed from a single output device to a digital input and output device.

(2) Features and advantages of digital printing machine: the output speed is 20, 30, 40, 50, 60, 70, 80, 100 pages per minute or even higher, which is suitable for a wide range of markets; Due to the addition of digital technology, the quality is stable; Simple equipment operation and clean working environment; Digital "group" service system has become a reality, making users more convenient; Low system cost and strong competitiveness; It is these characteristics of digital printing machine that we expect its broad development prospects.

2. Digital multifunction machine-developed from printer technology.

This kind of equipment is the same as the former in principle, but because they don't master the core technology of high-speed laser printers (except Canon and Xerox), most manufacturers' digital all-in-one machines can only compete in the low-speed market (below 30 pages per minute), and even compete for the fax machine market and printer market. It is difficult for this kind of equipment to enter the digital printing market.

Working principle of digital printing machine;

Digital printing machine consists of scanning unit, plate making unit, paper feeding unit, printing unit and paper discharging unit. When the printing machine is working, the manuscript enters the scanning unit, and the scanned words and pictures are converted into digital signals and transmitted to the thermal print head of the plate-making unit. Waxed paper used for plate making is melted by the thermal print head, so that the characters or pictures on the manuscript are engraved on the waxed paper in equal proportion, forming image information composed of tiny holes. After plate making, waxed paper engraved with characters or image information is automatically attached to the printing cylinder with ink. The rotation of the printing cylinder pressurizes the ink through the stencil hole and presses it on the paper passing between the printing cylinder and the pressure roller, and then the paper passes through the paper discharge unit and falls on the paper receiving table of the printing machine. When printing, this continuous printing action is completed in a short time (the plate-making time takes more than ten seconds). Once the newly manufactured printing plate is made, the printing speed can reach 90- 120 pages/minute. Due to the adoption of digital printing technology, the printing quality and efficiency have been greatly improved. It also provides great convenience for users who need to print in all walks of life.
