How does a digital printer work? Digital printing knowledge

For many customers with printing needs, there is a common problem, they have the need to print, but not quite clear how to calculate the cost of printing, the following is my compilation of how to use the digital printing machine? Digital printing essential knowledge, I hope to help you. Feel useful friends can share to more people oh!

1 specifications open

The following said the general color printing (offset) based, first of all, we need to know the specifications open, the normal sheet-fed paper specifications are divided into large degree and positive degree.

Large full sheet specifications for: 2975px * 2225px (47 inches * 35 inches), cut into two called Folio, cut four called Quadruple, cut eight called 8 open (A3), cut into 16 for 16 open (A4).

Positive degree of paper full sheet specifications for: 2700px * 1950px (43 inches * 31 inches), the same cut two for the positive degree of folio ...... and so on.

Generally leave 25px machine bite paper bite and 12.5px crosshairs on both sides of the set of color set quasi-position.

The thickness of the paper is generally calculated in grams of g, generally speaking 157g coated paper means that the thickness of this coated paper is 157 grams per square meter, the larger the number of grams of paper is thicker. Printing on the customary 500 full sheets of paper called 1 order of paper, paper is priced in tons, a variety of grams of thickness of paper per ton of the number of orders are not the same, there are tables can be referred to.

2 paper printing

For 4-color printing, the quality of the general first look at whether there is no register, printing dots are strong and clear, the layout of the paper there is no scuffing and scratching, trimming line has been printed, the text there is no pen breaks, whether the color is uniform, such as samples but also to check the proofing. Printing processing fees are usually calculated by the color order, that is, each order of paper printing a color called 1 color order.

3 post-press and other

There are also packaging, delivery, collection and so on. Generally take the business to sign the contract to be prepaid, normally 50% in advance, because the content of the printed materials is specific to only belong to this customer, if he does not want, others have no use.

Printing Classification

1 offset

Commonly known as color printing, using film through the plate machine sun in the pre-coated photopolymer plate (ps plate), and then printed on paper with an offset press, the general number of lines in the 175 lines / square inches, 175L / inch; offset presses have a single-color machine, two-color machine, four-color machine, five-color machine, etc.; specifications have a large number of sheets of paper, and so on. ; specifications have a large full-sheet machine, full-open, folio, four-open, eight-open, and so on.

3 screen printing

General printing of thicker patterns, printing materials such as cloth, plastic, paper, cardboard, etc., the printing plate is based on the mesh frame line, ordinary general 80 ~ 100 lines, we contact for paper, such as printing UV oil, to do the effect of sanding, local UV varnish.

4 flexo, watermarking

is to use the film pasted on the resin plate, rubber plate photographic corrosion or engraved 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

First of all, to understand the intention of the customer, the customer's company, address, telephone, contact person.

Operation

The digital printing machine breaks through the bottleneck of digital printing technology, realizing the true meaning of a start printing, no plate, full-color images at once. The extremely low cost of printing and high quality printing results than the traditional printing system is economical and convenient, minimal system investment, digital operation and limited space occupation, so that the system has a greater market prospects. It is the best supplement to the traditional printing, is the replacement of traditional printing machine. Digital printing machine is divided into industrial digital printing machine and office digital printing machine (that is, digital printing machine) according to the different uses. Office digital all-in-one representative is Toshiba, Konica, Ricoh, Canon, Xerox, OSI, etc.; industrial digital printing press is typically represented by the Kodak digital printing press, Komei, etc..

The digital printing machine is to make the digital printing world emerged a new force in the digital printing road for enterprises, factories, personal entrepreneurship opened up a fashionable and novel road.

Development Status

1, digital printing all-in-one machine - by the copier technology plus the development of digital technology

(1) Typical representatives: Toshiba, Konica, Ricoh, Canon, Xerox, OSI, etc.. This type of equipment generally includes three major parts: scanning part, laser printing part and folding and binding part. Its function is more comprehensive, can scan, copy, print and digital publishing.

This type of equipment belongs to the multi-functional digital printing system, is a class of digital printing, from the previous single . Output devices transformed digital input and output of one device.

(2) digital printing all-in-one features and advantages: output speed of 20, 30, 40, 50, 60, 70, 80, 100 pages per minute or even higher, to adapt to a wide range of markets; due to the addition of digital technology to ensure stable quality; equipment operation is simple, clean working environment; digital "" Group "" service system into reality, the user is more convenient; the system has a low cost. Strong competitiveness; it is the digital printing machine has these characteristics, we expect its development prospects.

2, digital MFP - based on the development of printer technology

This type of equipment from the principle of the same with the former, but because they do not master the high-speed laser printer core technology (except Canon, Xerox), so most manufacturers of digital all-in-one can only be in the low-speed (30 pages per minute) market competition. pages per minute or less) market to compete, and even compete for the market of fax machines and the market for printers. It is difficult for these devices to enter the digital printing market.

Working principle of digital printing machine:

Digital printing machine consists of a scanning unit, plate making unit, feeding unit, printing unit, and paper output unit. When the printing machine works, the original into the scanning unit, the scanned text and pictures, converted into digital signals, transmitted to the plate making unit of the thermal print head. The wax paper used for plate making is thermally fused through the thermal print head, so that the words or pictures on the original are engraved on the wax paper in equal proportion to form image information composed of tiny holes. After plate making, the wax paper engraved with text or image information is automatically laminated to the top of the printing cylinder with ink. The rotation of the cylinder pressurizes the ink through the holes in the waxed paper and imprints it onto the paper that passes between the cylinder and the pressure roller, and the paper then passes through the discharge unit and lands on the splice table of the printing press. At the time of printing, this coherent printing action is completed in a very short time (plate making time takes more than ten seconds), once the newly manufactured plate is made, the printing can be done at a speed of 90-120 pages per minute. Due to the use of digital printing technology, the quality of printing, printing efficiency has been greatly improved. Also for all walks of life need to print the user, provides great convenience.

Expansion: offset printing estimate

Then, ask if you want to design production, or just out of the film, proofing.
