Printing common sense

1. What is the basic knowledge of printing?

There are many kinds of modern printing technology, which can be divided into four basic types according to their printing plate types: relief printing, gravure printing, lithography and stencil printing.

Letterpress printing: The graphic part of the printing plate is convex, the blank part is concave, and the convex part is printed on paper with ink. Letterpress includes lead letterpress, lead whole edition, corroded copper (zinc) edition, engraved copper (zinc) edition, resin edition and woodcut edition.

Generally used for printing books, newspapers, letters (drafts), notebooks, envelopes, statements, letters of introduction, certificates, etc. Gravure printing: The graphic part of the printing plate is concave and the blank part is convex. After inking the whole page, the ink in the blank part is removed, and the ink in the concave graphic part is printed on the paper under greater pressure.

Gravure includes etching gravure and engraving gravure. It is generally used to print more exquisite stamps or important tickets, as well as patterns, patterns and characters of some handicrafts.

Lithography: The graphic part and blank part of the printing plate surface are basically on the same plane. When printing, the principle of oil-water repulsion is used, so that the blank part is stained with water and not with ink, and the graphic part is printed on paper. Lithographic printing includes offset printing plate, lithographic printing plate, intaglio and so on.

Generally used for printing pictures, calendars, art stationery, diaries, books and newspapers, magazines and various ticket patterns. Hole printing: The part to be printed of printed pictures and texts consists of many tiny holes through which ink is printed on paper.

There are stencil copying (printing), electronic transcription, screen printing and so on. Generally used for printing ordinary documents, reports, tabloids and other printed materials.

2. Why are there typos in pirated books? Can you introduce some knowledge about typesetting and printing?

In the process of making a book, a lot of review and revision are needed. After sorting out the words and pictures, hand them over to a book publishing company (such as a publishing house). When the electronic file of the sample is made, all the words and pictures are input into the computer to make a book, which is only the first step. Then, the file is output to the printing company. Then arrange proofing. In fact, there is no guarantee that the document is completely correct. Then the author or producer will revise it over and over again until all the files are OK. Pirated books generally can't get the final OK draft. Because printing companies usually make changes before printing, they will not make changes in publishing houses or related companies that publish this book. It is much less likely that the documents will be leaked from the printing company. Usually leaked from the production company. And a pirated book. After the book was printed, the manuscript was directly scanned. If you recognize the text directly, it will be risky. If scanning identification is ok, pirated books will not be much different except paper.

3. Printing knowledge

The traditional representation of printed matter conceals the connotation of technological innovation: traditional printed matter and traditional printing technology.

A book, a picture album and a paper box may be of high or low quality compared with the past, but it is still a traditional printed matter, and there is no difference. However, in the past, it was hard to escape the smelting of "lead and fire", but now it is easy to click on the computer from your fingertips. Therefore.

Although printing is still a traditional form, the traditional technology used in production has long been replaced, and the production efficiency has been greatly improved. Therefore, behind the traditional printed matter with unchanged appearance, there are a lot of technological innovations, many of which have been completely transformed in prepress and prepress process.

Let's learn about the printing industry first: 1. What are our main printing methods at present? (1) offset printing (widely used in China, with stable quality and technology, such as newspapers, books, packaging, PVC, stickers, etc.) (2) gravure printing (high-quality, large-volume printed products such as cigarette labels, wine labels, instant noodle pockets, sugar paper, etc.) (3) screen printing (according to printing characteristics, the number that can be printed is very small, and printing ink is used. (4) Flexo printing (printing and packaging, substrate materials are relatively extensive! It has unique advantages for plastic products and corrugated boxes. (5) Ink-jet printing (used to be mainly used for ink-jet printing of anti-counterfeiting bar codes, but now it can also perform well for relatively fine printed matter, especially for the short edition market, the biggest development is the use of digital proofing. In addition, the print format can be almost unlimited! The application in the market has a relatively stable market) (6) Transfer printing (the principle is like hot stamping, and the shapes of substrates that can be printed are also diverse, such as the printing of toothpaste skin, which is faster than screen printing! (7) DIgital printing (the most representative ones are Di series of Heidelberg, DICO Yu and HPINDIGO； of Roland; Some of Xerox's products (inkjet printing is often classified into this category) have the characteristics of short printing preparation time, which has unique advantages for batch print.

The market trend is of course self-evident), in fact, there are many other printing, but all of them can produce some special effects in printing, such as lithograph printing, and printing Chinese paintings on rice paper can have a good artistic effect! Offset printing: 2. What are our common printed materials? Classification of printed matter (by final product): (1) Office category: refers to office-related printed matter such as stationery, envelopes and office forms. (2) Publicity category: refers to a series of printed materials such as VI manuals, posters, leaflets, promotional samples, product manuals, desk calendars, calendars, invitations, hand-held paper bags and so on related to enterprise publicity or product promotion.

(3) Production category: refers to large quantities of printed matter directly related to product production, such as packaging boxes and self-adhesive labels. 3. What is the workflow of printed matter? Printing process: (1) prepress refers to prepress work, which generally refers to photography, design, production, typesetting, film production, etc. (2) Printing refers to the process of printing finished products through a printing machine in the middle stage of printing; (3) Post-printing refers to the post-printing work, which generally refers to the post-processing of printed matter, including cutting, laminating, die-cutting, bagging and mounting. , mainly used for publicity and packaging printed matter.

4. What are the main printing related equipments at present? (1) prepress equipment: film printer, proofing machine, computer, color inkjet printer, laser scanner, etc. (2) Printing equipment: roller press: printing newspapers, books, magazines and picture books, made in China and imported; According to the size of printing format, it can be divided into full-open printing machine, counter starter, four starter and eight starter; According to the printing color number of the printing machine, it can be divided into monochrome printing machine, two-color printing machine and four-color printing machine.

Printing equipment is divided into manual operation, mechanical operation and computer automatic operation equipment. (3) Post-press equipment: some post-press processing equipment such as pagination machine, paper cutter, bronzing machine, embossing machine, die cutter, coding machine, laminating machine and binding machine.

(4) Other printing equipment: self-adhesive printing professional machine, computer-specific sheet-fed printing machine, business card special machine, rapid printing machine, copier, packaging, carton printing machine, etc. 5. What are the mainstream printing equipments in the domestic printing industry? Take four-color printing as an example: Heidelberg (Bakai country of origin: Germany), Gaobao (Fang Kai country of origin: Germany), Komori (Japan country of origin: Japan), Liang Ming (Case country of origin: Japan) and Roland (Germany country of origin: Shanghai country of origin). Among them, European and American printing press manufacturers rely on their cutting-edge product technology, comprehensive printing solutions and excellent services.

6. What is four-color printing? (1) What is four-color printing? Four-color printing process generally refers to the printing process that uses yellow, magenta, cyan ink and black ink to copy the color of color original. (2) What is spot color printing? Spot color printing refers to the use of yellow, magenta and cyan.

The printing process of using four-color black ink and copying the original color with other colors of ink. Spot color printing technology is often used in packaging printing to print a large area of background color.

(3) What products must adopt four-color printing process? Because of technical requirements or economic benefits, color photographs that reflect the richness of nature, artists' colorful works of art or other pictures with many different colors must be scanned and separated by electronic extension or color desktop system, and then copied by four-color printing process. 7. What do you know about printing paper? (1) unit of paper: a.g: weight of one square meter of paper; B order: 500 sheets of paper (factory specifications); C. Ton: 65,438+0 ton = 65,438+0,000 kg is used to calculate the paper price as usual.

(2) Paper specifications and names A. There are four most common specifications of paper: ① Positive paper: length 1092 mm, width 787mm；; ② Large paper: length 1 194 mm, width 889mm；; (3) Carbonless copy paper: There are generous specifications on the front, but there are upper paper, middle paper and lower paper, and the paper prices are different, among which the middle paper is more expensive. B. The most common name of paper: A. Typing.

4. What is the basic knowledge of printing?

Small black letters should be single black, and the positive film should be stacked at the bottom. Use compound color for big black characters, otherwise the printing will be false;

Bleeding: leave 2-3 mm for general paper, 5 mm for 3-layer corrugated box and 8mm for 5-layer corrugated box.

The mode needs to use CMYK, and the resolution now advocates 200-line printing with a resolution of 350-400;

The following is what I added:

There is also the need to know the size of the paper used for assembly, and the paper mouth should be reserved for assembly. Different paper prints different colors, so when designing, priority should be given to what paper to print first before designing;

Multi-color background color tries to avoid white characters, which is easy to misregister; Try to avoid a large area of background color, which is easy to spend when printing, giving people a ghost;

Spot color printing, try to choose overprint, not overprint. Considering what I want to add, let's talk about this first.

I hope it helps you:-)

5. Printing knowledge

Printing knowledge 1. How long is the printing cycle of the order? 2. How to prepare for pre-printing? 3. How to prepare prepress documents for printing? 4. Chromaticity difference of film, proofing, printed matter and computer screen: 5. How is the quotation for printing formed? 6. printing paper? 1. How long is the printing cycle of the order? Your delivery time depends on the requirements of the printing order.

Our production cycle is usually 3- 8 working days, usually within 4 working days. There are many post-press processes, such as laminating, binding, pasting, die cutting and bronzing.

It usually takes more than 7 working days, and our long-term customers enjoy the service of free charge in Zhuocheng. 2. How to prepare for pre-printing? With a fine division of labor in each process, you can easily find a professional prepress producer to provide you with quick and thoughtful service. Of course, we can also provide you with typesetting, design and production of prepress documents, and we can provide you with a full set of movies and proofing. We suggest that you do the above film pasting and proofing.

This will ensure your delivery time and minimize intermediate links and costs. 3. How to prepare prepress documents for printing? If you don't have time to go to the prepress production company to complete the film production and proofing, we will immediately assist you to complete the prepress production.

Please pay attention to the following aspects of your certificate, which will help you save valuable time. 1. Please make sure that all necessary files are in the document, and make sure that image files must be included in the document. Sometimes, although images can be displayed, they actually lack pictures or have low resolution, so please determine the necessary images and provide accurate image files in the document.

(The picture resolution is not less than 280 pixels/inch) 2. Don't forget to copy the necessary fonts, and make sure to provide the necessary styles. Although some fonts are displayed, you still need to copy printable fonts to output the movie. Only by ensuring that characters can be displayed and input can we not waste our time.

Don't forget to change the color of the linked picture from RGB to CMYK, otherwise there will be color confusion after the film is released. 4. When Pantone spot color is converted to CMYK color, please confirm whether the same effect will be achieved.

After Pantone spot color is converted to CMYK, there will be some differences between them. After some Pantone spot colors are converted into CMYK, the same effect can be achieved according to the output experience, but those process Pantone colors are definitely not achieved by CMYK, and can only be solved by adding spot colors. 5. Double scanning of pictures; Single output can improve the scanning quality of pictures.

6. The simple question of whether the typesetting file is set to bleed 3mm often makes some experienced computer experts lose their virginity; Is the color in typesetting software set according to the color scale value? So please do one last check. 7. Printing proofing corresponding to the film is the most worry-free reference for the printing factory.

If there is no proofing for various reasons, please provide at least one printed copy (color is the best, there is no such thing, and black and white will do). We must check the film with one of the above two. 4. Chromaticity difference of film, proofing, printed matter and computer screen: Film and its corresponding proofing are the best choice to reduce errors and save cost and time for you and us.

The proofing corresponding to the film is the closest to the printed matter. The printed matter displayed on the computer screen is much brighter than the actual printed matter, so it cannot be used as an equivalent reference, and the printing proofing shall prevail.

This is because the color formation of display and color printing paper products is very different. The display uses three primary colors of red, green and blue to emit light to form an image. The principle of this color formation is called RGB, which is widely used in TV and computer monitors.

Color printing is to print red, yellow, blue and black ink on paper products to form color images. This principle is called CMYK, which is widely used in four-color offset printing technology. Another important reason is the obvious difference between computer monitors and printed matter, that is, the color standard of monitors.

If the color of your computer monitor is not calibrated correctly, the computer display effect will be very different from that of a properly calibrated computer monitor. Therefore, it is necessary to ask professional and technical personnel to adjust the display effect in time.

Different printing materials will also make the printing effect different. Generally speaking, the printing effect of coated paper is much brighter than that of offset paper.

The above preparations can help you and us to reduce various possible problems. Accelerate the delivery process to avoid increasing costs.

Nevertheless, if you lack each of the above tasks or don't quite understand our suggestions, please don't worry. We will try our best to cooperate with you under various conditions. Just please try to provide all the documents you can; We will call you at any time after finding the problem to confirm the smooth completion of the work. 5. How is the printed quotation formed? Color printing is the most accurate description of human behavior and product service.

It brings a profound and indelible first impression and feeling to human beings, and its accurate expression can have the greatest impact on human emotions and decisions, especially on purchasing decisions and customer satisfaction after receiving services. As an important part of product promotion, color printed matter is a key link and assistant related to the success or failure of enterprises.

When making product promotion and sales budget, customers will be anxious to know the cost of printed matter. As long as you fill in our quotation, our customer service staff will reply to it for you. If it is the first time to contact printing inquiry and contact the printing factory, you may feel at a loss, so please read our workflow and fill in our quotation quickly.

The printing process can be simply divided into three parts: prepress, printing and postpress. The accounting of printing cost can also be divided into the above three parts, and the integration of the three parts is the price of printed matter.

Pre-press: The process of finishing film and proofing is calculated at the unit price. Generally A4 (if it is less than A4 or greater than A4, it is A3, so you need to measure the exact size to check the price) is the usual pricing standard. Film is a necessity on the computer, and printing and proofing is the most basic proof to check the pilot's color.

Printing: it is the key link of printing, and the pricing standard is color list. If.
