Printing knowledge

1. What is the basic knowledge of printing

There are many types of modern printing technology, such as according to the type of its printing plate type can be categorized into four basic types: that is, letterpress printing, gravure printing, lithography, and hole version of the printing.

Letterpress: the graphic part of the printing plate is raised, the blank part is concave, raised part of the ink printed on paper. Letterpress includes lead live plate, lead whole plate, corrosion copper (zinc) plate, engraved copper (zinc) plate, resin plate and woodcut plate.

Generally used to print books, newspapers, letters (manuscript) paper, notebooks, envelopes, statements, letters of introduction, documents and so on. Gravure printing: the graphic part of the printing plate is concave, the blank part is raised, after the inking of the whole plate, the blank part of the ink will be removed, and the concave graphic part of the ink will be printed on the paper under greater pressure.

Gravure includes corrosion intaglio and engraved intaglio. Generally used to print the more exquisite stamps or important stamps and symbols of patterns, designs and text and certain arts and crafts.

Lithographic: the surface of the printing plate graphic part and the blank part of the basic in the same plane, the printing of the use of oil and water refusal principle, the blank part of the water does not stain the ink, so that the graphic part of the ink printed on the paper. The lithographic plate includes offset plate, lithographic plate, flat concave plate, etc..

Generally used to print pictures, calendars, art letterhead, diaries, books, newspapers, magazines and a variety of ticket patterns. Hole plate printing: the printing of graphics to be printed part of the composition of many fine holes, ink through the small holes printed on paper.

Hole version of the transcription (print) wax version, electronic transcription shadow version, screen version of the raw and so on. Generally used to print ordinary documents, reports, tabloids and other printed matter.

2. pirated books why there will be typos can introduce some knowledge about typesetting and printing

A book in the production process, there are a lot of review and correction. After the text and pictures are organized, to the book company (such as publishers), out to the sample manuscript electronic files, that is, all the words and pictures are entered into the computer and made into a book, this is only the first step. Next, the file is sent to the printing company, which then arranges for the proofs to be made. There is no guarantee that the file will be correct. Then the author or producer has to make corrections and changes again and again until the file is OK, and in the case of pirated books, there is usually no way to get a final OK copy. This is because the changes are usually made in the printing company's pre-press, not in the publishing house or the company that produces the book. It is much less likely that the files will leak out of the printing company. They usually leak from the production company. There is also the case of pirated books, where the book is printed and then scanned directly into the manuscript, which can be risky if the text is recognized directly. If the scanning recognition is not a problem, this pirated book in addition to the paper is not the same, the other will not have much difference.

3. Knowledge of printing

The traditional appearance of printed materials obscures the connotation of technological innovation: traditional printed materials and traditional printing technology.

A book, a picture album, a carton now compared to the past, there may be a difference in quality, but still for the traditional print, there is no difference, but in the past, it is difficult to escape the "lead and fire" smelting, and now they are all from the fingertips in the computer easily click. The first thing you need to do is to get your hands on a computer and then click on it.

Although the printing is still the traditional form, but the production of traditional technology used in the process has long been replaced, the production efficiency has been greatly improved. Therefore, in appearance, although no change in the traditional printed materials behind the cover of a large number of technological innovation, through the pre-press and post-press, a lot of change is still off the charts.

First, let us understand the printing industry: 1, at present, our main printing methods are? (1) offset printing (in China is quite widespread, the quality of the process is stable, such as newspapers and magazines, packaging, PVC, stickers) (2) gravure printing (cigarette labels, wine labels, instant noodle pockets, sugar paper and other printing quality requirements of the high printing quantity of printed materials) (3) screen printing (according to the characteristics of the printing, can be printed in a small number of tens of sheets can be printed, the shape of the printing plate can be changed, for example: can the curved surfaces, the printing plate can be changed, the printing plate can be changed to the curved surfaces, the printing plate can be changed to the curved surfaces. The shape of the printing plate can be changed, for example: can be printed on the curved surface, substrate a wide range! Printing ink layer is thick, the mesh can not be changed, so you can use mercerized ink, Ice Shantou ink with UV to do special effects!) (4) Flexo (printing packaging products, substrate materials are relatively wide! (4) Flexo (printing packaging, substrate materials are relatively wide! Eucalyptus for plastic products and corrugated cardboard boxes, etc. has a very unique advantage) (5) Inkjet printing (previously used mainly in anti-counterfeiting bar code printing, now for the more fine prints can also have a better performance, especially for the short version of the market, the biggest development is the use of digital sampling. In addition, the printing format can be almost unlimited! (In the application of the market has a more stable market) (6) pad printing (principle is like stamping, can print the shape of the substrate is also diverse, such as toothpaste Jane's printing, relative to silkscreen printing speed to be faster!) (7) digital printing (more representative of the DI series of HEIDELBERG, and ROLAND's DICO Yuk, as well as HPINDIGO; Xerox's some of the products, etc. (many times people also inkjet printing into this category) itself is characterized by printing preparation time is short, for the short version of the printing has a unique advantage.

Market trends are, of course, self-evident), in fact, there are many other printing, but out of some of their own characteristics can produce some special effects on the printing of live, such as lithography, the printing of Chinese paintings on rice paper can have a very good artistic effect! Offset printing: 2, what are our common printed matter? Classification of printed matter (to the ultimate product classification): (1) office class: refers to letterhead, envelopes, office forms and other office-related printed matter. (2) publicity: refers to VI manuals, posters, leaflets, promotional samples, product manuals, calendars, wall calendars, invitations, hand bags and a series of promotional or product publicity related to corporate printed materials.

(3) production category: refers to the box, stickers and other large quantities of printed materials directly related to the production of products. 3, what is the workflow of printed materials? Printing process: (1) pre-press refers to the pre-printing work, generally refers to photography, design, production, layout, film, etc.; (2) printing refers to the printing of the middle of the work, the process of printing finished products through the printing press; (3) printing refers to the printing of the latter part of the work, generally refers to the post-processing of the printed materials, including cutting, laminating, die-cutting, gluing bags, laminating and so on, mostly used for promotional and packaging printed materials.

4, what are the main printing-related equipment? (1) pre-press equipment: film hair row machine, proofing machine, computer, color spray machine, laser scanner. (2) printing equipment: cylinder press: printing newspapers, books, magazines, albums, there are domestic and imported points; according to the size of the printing format can be divided into full-open press, folio, four-open, eight-open; according to the number of colors printed on the press is divided into monochrome, two-color printing machine, four-color printing machine and so on.

Printing equipment is also divided into manually operated, mechanically operated, computerized fully automatic operation of the equipment. (3) post-press equipment: page splitter, paper cutter, hot stamping machine, embossing machine, die-cutting machine, coding machine, laminating machine, binding machine and some other post-press processing equipment.

(4) other printing equipment: self-adhesive printing professional machine, computer-specific bill printing machine, business card special machine, speed printing machine, copier, packaging, carton printing machine. 5, the domestic printing industry mainstream printing equipment? Four-color machine, for example: Heidelberg (eight open Origin: Germany), Gobel (folio Origin: Germany), Komori (Origin: Japan), Liang Ming (four open Origin: Japan), Man Roland (Origin: Germany), Guanghua (Origin: Shanghai), which Europe and the United States manufacturers of printing presses, with its cutting-edge products and technology, a comprehensive printing solutions and quality services, to become the world's leading printing presses and related equipment.

6, what is called four-color printing machine? (1) What is meant by four-color printing? Four-color printing process generally refers to the use of yellow, magenta, cyan three primary colors of ink and black ink to reproduce the color originals of the various colors of the printing process. (2) What is meant by spot-color printing? Spot color printing refers to the use of yellow, magenta, cyan.

Black ink four-color ink in addition to other color ink to copy the original color printing process. Spot color printing is often used in packaging printing process to print large areas of the base color.

(3) What products must use four-color printing process? With color photography to reflect the way the colorful changes in nature, photographs, painters of color art works or other images containing many different colors, for the process requirements or for economic efficiency considerations, must be scanned by the electronic separator or color desktop system color separation, and then use the four-color printing process to reproduce the completion of the process. 7, printing paper know how much? (1) the unit of paper: A. Grams: the weight of a square meter of paper; B. Order: 500 sheets of paper unit called order (factory specifications); C. Tons: the same unit as usual 1 ton = 1000 kg, used to calculate the price of paper.

(2) paper specifications and names A. The most common paper has four specifications: ① degree paper: 1092 mm long, 787 mm wide; ② degree paper: 1194 mm long, 889 mm wide; ③ carbonless paper: degree and degree specifications, but there are on the paper, in the paper, the paper, the lower part of the price of the paper is different, in which the paper is more expensive. B. The most common names of paper: a. Typing.

4. What is the basic knowledge of printing ah

Small black characters with a single black, but also the positive film overlay. Large black characters to use the compound color, otherwise the print is not real;

Bleeding: the general paper to stay 2-3mm, 3 layers of corrugated boxes to stay 5mm, 5 layers of corrugated boxes to stay 8mm;

The mode of CMYK is a must, the resolution of the 200 lines of printing is now advocating the resolution of 350-400;

The following said that I added:

There are also groups of plate Need to understand the size of the paper, the joint good version to leave the paper gripper. Different paper printed colors are not the same, the design should give priority to what paper printing and then do the design;

Compound color background color as much as possible to avoid anti-small white characters, easy overprinting is not allowed; try to avoid large areas of the background color, printing is easy to spend, out of the ghost;

Spot-color printing as much as possible to choose the overprinting, do not overprinting, first of all these bars, taking into account what I added.

I hope to help you :-)

5. Knowledge of printing

Printing common sense 1. How long is the printing period of the order? 2. How to prepare for printing? 3. How to prepare for printing pre-press production files? 4. film, proofing, printing and computer screen chromaticity difference: 5. printing of the offer is how to form? 6. Printing paper? 1. How long is the printing period for an order? Our delivery time for you depends on the requirements of the printing order.

Our production lead time is usually 3-8 working days, usually within 4 working days. In the case of more post-press processing, such as lamination, binding, laminating, die-cutting, foil stamping, etc., we can provide you with the best service.

Generally more than 7 working days, our long-term customers in the Zhuo Cheng enjoy urgent work free of charge expediting fee service. 2. How to prepare for printing? The various processes are divided into more detailed, you can very easily find a professional pre-press production company can provide you with fast and thoughtful service of course, we can also provide you with pre-press file layout, design and production, we can provide you with a full set of film and proofing, we recommend that you do a good job for the above film and proofing.

This will ensure your delivery time, maximize savings and reduce intermediate links and expenses. 3. How do I prepare my pre-press files for printing? If you don't have time to go to a prepress company to complete your film and proofs, we will assist you with your prepress work right away.

Please pay attention to the following aspects of the files you bring with you, as they will help you save valuable time. 1. Please make sure that all the necessary files are in the document. Please make sure that the image files are included in the document, sometimes the image may be presented in the display, but in fact it is missing or the resolution is low, so please make sure that the necessary images and provide the image files with sufficient accuracy in the document.

(The resolution of the image should be no less than 280 pixels per inch.) 2. Don't forget to copy the necessary fonts, and be sure to provide the necessary fonts, as some fonts, even though they may be displayed, need to be copied into a print-ready font in order to be able to output the film. Only ensure that you can display and input fonts so as not to waste your time.

3. Don't forget to change the color of the linked image from RGB to CMYK, otherwise the output film will be confused. 4. 4. When Pantone spot colors are converted to CMYK colors, please make sure that the same effect is achieved.

Pantone spot color into CMYK, the two generally produce some difference, some Pantone spot color into CMYK, according to the output experience can achieve the same effect, but those Process Pantone Color is certainly CMYK can not be achieved, then only with the increase of spot color method to solve the problem. 5. Picture double scanning; single output, you can improve the scanning quality of the picture.

6. layout of the document is set up to bleed 3mm, this simple issue is also often let some senior experience in the computer guru halted; layout software in the color according to the value of the color scale set up? So please do a final check. 7. Printing proofs corresponding to the film is the most worrying reference for printers.

If for various reasons there is no proof, please be sure to provide at least one print (color is the best, really no, black and white or not), we must be one of the above two to check the film. 4. The chromaticity difference between the film, proof, print and computer screen: The film and its corresponding proof is the best choice to reduce the error and save your cost and time with us.

The proof corresponding to the film is closest to the finished print. The computer screen display is much brighter than the actual print and cannot be used as an equivalent reference, so the printed proof should be used as a guide.

- This is because monitors are very different from the color formation of color printed paper. The monitor applies the principle of red, green and blue three primary colors to emit light to form an image, the principle of color formation is called RGB, which is widely used in television and computer monitors.

- Color printing is the red, yellow, blue, black ink printed on paper products to form a color image, this principle is known as CMYK, which is widely used in four-color offset printing technology. - Another important reason for the apparent difference between computer display and print is the color standard of the monitor.

If your computer monitor is not calibrated correctly, then the computer display will be very different from a properly calibrated computer monitor. So it's important to have a professional technician adjust the display in a timely manner.

- Different printing materials can also make a difference in the printing effect. Generally speaking, coated paper produces brighter colors than offset paper.

All of the above preparations will help you and us to minimize any problems that may arise. This will help you and us to minimize any problems that may arise, and to speed up the delivery process to avoid costly surprises.

Nevertheless, if you lack each of these tasks or do not understand the requirements of our proposal, do not worry, we try to work with you under all conditions. We just ask that you provide as much documentation as you can; we'll call you anytime we see a problem to make sure the job is done right. 5. How is a print quote formed? Color printing is the most accurate means of describing human behavior and products and services.

It creates a deep and indelible first impression and feeling, and its precise representation can positively influence human emotions and decision-making, especially purchasing decisions and customer satisfaction after receiving services. Color prints are often used as an important part of product promotions, and are a key link and aid to the success or failure of a company.

Customers will be eager to know how much the printed materials will cost when they create their sales budgets for product promotion, so if you fill out our quote form, our customer service staff will get back to you with a quote. If this is your first time contacting a printer for a quote and contacting the printer, you may not be able to get started, so please read through our workflow and fill out our quote quickly.

The printing process can be simply divided into three parts: pre-printing, printing, printing. The cost of printing can also be divided into these three parts, the three together is the price of the printed product.

Pre-printing: the completion of the film and proofing process is calculated per P, generally A4 (if less than A4 or greater than A4 that is, A3, so be sure to measure the exact size, so that it can be used for pricing) for the usual pricing standards. FILM is a necessity on the machine, printing proofs is the most basic document to lead the machine to check the color.

Printing: is the key link in the completion of the print, the pricing standard is the color order. If.
