Letter paper

The letterpress paper uses the main paper for letterpress printing of books and magazines. It is suitable for texts such as important works, scientific books, academic journals and textbooks for colleges and universities. The letterpress paper can be divided into four grades of No. 1, No. 2, No. 3 and No. 4 according to the distribution ratio of the paper materials. The number of papers represents the quality of the paper. The larger the number, the worse the paper quality.
Letterpress paper is mainly used for letterpress printing. The characteristics of this paper are similar to, but not identical to, newsprint. The paper structure of the relief paper is relatively uniform, and the gap between the fibers is filled with a certain amount of filler and rubber, and is also bleached, which forms a good adaptability of the paper to printing. Although its ink absorption is not as good as newsprint, it has the characteristics of uniform ink absorption; water resistance and whiteness of paper are better than newsprint.
The relief paper has uniform texture, no lint, slight elasticity, opacity, slight water resistance, and certain mechanical strength.

Newsprint

Newsprint is also called white paper, which is the main paper for newspapers and books. Applicable to newspapers, periodicals, textbooks, comic strips and other text papers. The characteristics of newsprint are: paper is light and has good elasticity; ink absorption performance is good, which ensures that the ink can be fixed on the paper. After calendering, the paper is smooth on both sides, no lint, so that the two sides of the print are clear and full; have a certain mechanical strength; good opacity; suitable for high speed rotary printing.
This kind of paper is made from mechanical wood pulp (or other chemical pulp) and contains a lot of lignin and other impurities. It is not suitable for long-term storage. If the storage time is too long, the paper will become yellow and brittle, and the water resistance is poor. It is not suitable for writing. Printing ink or book ink must be used, the viscosity of the ink should not be too high, and the moisture of the layout must be strictly controlled during lithography.

Offset paper

Offset paper is mainly used in lithographic (offset) printing machines or other printing machines to print higher-grade color prints, such as color pictorials, albums, posters, color labels and some advanced book covers, illustrations and so on.
Offset paper is divided into special numbers, No.1 and No.2 and No.3 according to the proportion of paper pulp. There are single-sided and double-sided parts, as well as super-calendering and ordinary calendering.
The offset paper has small stretchability, uniform absorption of ink, good smoothness, tight opacity texture, good whiteness and strong water resistance. Conjunctival offset printing ink and good quality printing ink should be used. The viscosity of the ink should not be too high, otherwise powder removal and pulling will occur. Also to prevent the back side from getting dirty, generally use anti-dirty agent, dusting or lining paper.

Coated paper

Coated paper, also known as coated paper, is made by coating a layer of white paste on a base paper and calendering it. The paper has smooth surface, high whiteness, uniform distribution of paper fibers, uniform thickness, small stretchability, good elasticity and strong surface smoothness, high whiteness, uniform distribution of paper fibers, uniform thickness and flexibility. Small, with good elasticity and strong water resistance and tensile properties, the ink absorption and receiving state is very good. Coated paper is mainly used for printing albums, covers, postcards, exquisite product samples, and color labels. The pressure of the coated paper should not be too large, and the offset resin ink and the bright ink should be used. To prevent the back side from getting dirty, you can use methods such as adding anti-dirty materials and dusting. Coated paper has two types, single and double.

1, nitrocellulose (NC) color film
Nitrocellulose (nitrocellulose), light white or light yellow floc, insoluble in water, soluble in organic solvents, ketones, esters, alcohol ethers, nitrogen content is generally 11% to 13%. According to the high and low nitrogen content, the screen printing ink is divided into L type and H type by nitrocellulose, and the nitrogen content ranges from 10.7% to 11.4% and 11.5% to 12.2%, respectively.
The nitrocellulose series color film is made of high quality organic pigment, and the nitrocellulose is used as the carrier resin to pre-disperse the pigment in the carrier resin, and the carrier resin is used to coat the pigment. Used in the manufacture of printing inks, wood, cosmetics, leather products; NC series of color films have been successfully applied in gravure flexo printing inks in the packaging field, especially cigarette inks.
The pigment content of NC series color film is 60%~65%, which enables the ink formulator to directly load into the ink formula or to produce the color paste with maximum flexibility, and then make the ink by adding the color paste to the varnish. . The NC series of colorants are easily dispersed on a high speed disperser, giving high color density and gloss.
2. Waterborne acrylic (AC) color film
The water-based acrylic color film is a product which is made of a high-quality organic pigment and a pre-dispersed pigment in a carrier resin using a high-grade water-based acrylic resin as a carrier. This series of colorants is used in water-based printing inks and has been used in water-based inks for paper flexographic printing, such as preparation, food and beverage packaging.
The water-based acrylic color film has a pigment content of 65% without adding any additives, so that the AC water-based color film can give the ink formulation maximum flexibility in application, directly into the ink formulation or first into a color paste, and then a color paste. The ink is added in the form of a varnish to form an ink, and a suitable aqueous resin is used to produce the desired ink. The water-based acrylic color film is easily dispersed on a high-speed disperser, giving a high color density and gloss, and is convenient for transportation and long storage time.
3, chloroacetic resin (VC) color film
Chloroacetate resin is a copolymer of about 86% vinyl chloride and 14% vinyl acetate, mainly used as a binder for inks and adhesives. Due to the solubility of the chloroacetic resin and the excellent fluidity of the formulated color paste, the formulated ink and coating have excellent toughness, flex resistance, excellent tear resistance and excellent adhesion. Chloroacetate resin is compatible with all series of chloroacetic acid products, and has good compatibility with other copolymers, polyvinyl chloride and acrylic resins, as well as phenolic resins and alkyd resins.
The chloroacetic resin VC color film has a pigment content of 60% to 65%, and can be directly loaded into the ink formulation or added to the varnish in the form of a varnish without any additives. Mainly used in screen printing inks and gold and silver cardboard printing inks.
4, polyvinyl butyral (PVB) color film
The polyvinyl butyral color film is a product in which a pigment is pre-dispersed in a polyvinyl butyral carrier resin, and the pigment is coated with a carrier resin. The content of the pigment in the polyvinyl butyral color film is 50% to 60%, and is directly loaded into the formulation or firstly produced into a color paste to form a finished ink. Easy to disperse in high speed dispersers, giving high color density, gloss and transparency. It is used in printing inks, print cartridges, colored markers and other materials in various packaging fields.

Depending on the type of solvent used, it can be divided into solvent-based flexographic inks, alcohol-soluble flexographic inks, water-based flexographic inks and UV-curable flexographic inks.

The main uses of flexographic printing inks:
(1) Solvent-based flexographic inks are mainly used for printing non-absorbent substrate materials, and their interchange is better. Usually the print is dried by volatilization of the solvent in the ink.
(2) Alcohol-soluble inks are used for printing absorbing substrates. The alcohol-soluble ink is obtained by replacing an alcohol-soluble resin with an alcohol-based solvent, and further mixing and mixing the ester solvent and the cellosolve with the colorant. Alcohol solvents are the least toxic of organic solvents. They do not corrode and damage the flexographic printing plates, but they are harmful to the environment and safety.
(3) Water-based ink refers to a flexographic printing ink using water, alcohol, cellosolve or the like as a solvent, and is mainly used for printing of an absorptive substitute printing material such as paper, cardboard, corrugated paper, cement bag, and the like. Water-based inks are mainly classified into three types: alkali-soluble, emulsion-type and water-soluble. Currently, water-soluble water-based inks are mainly used. It is characterized by less organic solvents used and less harmful gases emitted, which is beneficial to the improvement of the environment.
(4) UV-curable flexographic ink is a liquid ink that can be converted from a liquid to a solid under a certain wavelength of ultraviolet light. It is mainly used for the printing of products with high quality requirements. It has the characteristics of small dot enlargement rate, good film formation, high gloss, abrasion resistance, chemical corrosion resistance and no pollution. It has a wide range of applications and can be printed on any substrate.

Books are a must-have for learning. The quality of books has a great impact on people’s reading experience. How do books print better? Let’s talk about the two mainstream printing methods.

1. Contact Imprinting

Contact imprinting is a printing technique that uses pressure-based printing to transfer graphic information on an original to a substrate using a plate or other means. Contact imprinting is also a traditional method of printing. It uses ink or coloring pigments to reproduce images and text on the surface of paper or other materials with the aid of printing machinery. According to the printing process, the printing process generally includes five elements such as an original, a printing plate, a substrate, an ink, and a printing machine. According to the form of the printing plate, the contact embossing printing mainly has four categories: letterpress, gravure, lithography and stencil printing. According to the printing procedure, the above four printing methods have different direct printing and indirect printing. There are also different classification habits in the application field. China generally divides this into news printing, publishing and printing (including books and magazines), packaging and decoration printing, securities printing, stationery printing and parts printing.

2. Non-contact printing

Non-contact printing, also known as pressureless printing, is a printing technique based on the use of no pressure. It is a new form of printing that has emerged with the development of electronic computer output technology.
Instead of using traditional plates, it uses thermal, static, magnetic or inkjet technology to send toner or ink droplets to the surface of the substrate under computer control; or to make special papers that are colored to form clear images. . Non-contact printing has the characteristics of reliable operation, no noise, compact equipment, fast speed, convenient operation and wide adaptability. It is especially suitable for copying in the office environment and outputting hard copies for information network systems, providing a small number of various files and materials. Pressureless printing includes laser (electrostatic) printing, inkjet printing, thermal printing, and magnetic printing. Among them, the first two are the widely used pressureless printing methods.

How long have you not read a book well?
You may say: I have been watching all the time. I have paid a lot of attention to gongzhonghao in my mobile phone. The articles inside are very classic. I also have a lot of listening software on my mobile phone, and I can listen to books anytime, anywhere.
Then ask: Do you remember what they are talking about? Can you benefit from it? It’s probably a glimpse.
There is a truth, I think everyone has heard it: Nothing to read more, there are not a few that can really be done.

A mentor in college, he often warned us to read more. He said that he was busy and tired during the day, and in the evening he would put down his mobile phone and go to the study to read the book quietly.
When he shared with us his reading experience or life experience in class, our whole class will listen to it very seriously. It is really he talks and talks, we concentrate. Every time I listen to his sharing, we will benefit a lot, and then we can continue to go to the library to study for a long time.

Why I have never read a book because I don’t have enough control over my phone. There used to be a long time, I was crazy with the mobile phone: the king can play until 11:25 in the evening, read the novel can see two or three in the morning.

Eat and watch mobile phones, walk to see mobile phones, go to the toilet and watch mobile phones. Why am I so obsessed with mobile phones? Probably as people say: People are lonely, so I always think that I can seek a little comfort from my mobile phone, but the result is more Playing with a mobile phone, the heart feels empty.
Later, I really couldn’t stand my own decadence, and I started to force myself to put down my mobile phone. I discovered that sometimes I can do a lot of things when I put down my mobile phone. Every time I finish one, my heart is especially satisfying and practical.

At the beginning, I picked up a book. If I didn’t read 10 pages, I would be sleepy. Then the insomnia that I usually play with my mobile phone was directly cured. I could sleep with a pillow. After a period of time, I can concentrate on watching for an hour. Later, I can read the two or three hours of books with gusto, and occasionally do some reading notes.

If I tell you that you can get a lot of reading through hours and days of reading, it is a fake, but the sentiment is definitely not less. Although the content of the book is not as colorful as the mobile phone, even it seems more boring, but what we can learn is real.
Gorky said that “books are the ladder of human progress.” This is not a false statement. Reading can not only calm your impetuous heart, but also make your spiritual world more full.
For example, Dong Qing, who has a poetry and poetry since the beginning of his life, Wang Han, a true gentleman of the book, is a good example of persistence in reading. In their words and deeds, they always reveal a “book smell” that is emitted from the inside out.

After the invention of papermaking in 105 AD, papermaking was spread from Henan to other areas with developed economic and cultural properties. Cai Lun was sealed to Longting Hou in Yangxian, Shaanxi Province, and papermaking was transmitted to Hanzhong and gradually spread to Sichuan. In the processing and manufacturing technology, the lye cooking and crucible are strengthened, the quality of the paper is improved, and processed paper such as colored paper, filled paper, and filler paper appears.

1, offset paper (Dawlin paper)

The offset paper is divided into three types according to the ratio of paper pulp, No. 1 and No. 2, and there are two sides, one side and two sides, and two levels of super calendering and ordinary calendering. The paper weight is 50, 60, 70, 80, 90, 100, 120, 150, 180 (g / m2), of which the commonly used double-sided offset paper has 70, 80, 90, 100, 120 (g / m2), single Offset offset papers are available in 50, 60, 70, 80 (g/m2).

White paper is composed of pulp and noodles, and the pulp is white. The pulp is generally the natural color of the raw materials. White paper is divided into two types according to the paper surface: white and white. According to the bottom layer, there are two kinds of gray bottom and white bottom. The quality requirements of white paper: white, smooth, uniform thickness, firm texture, no powder removal, uniform ink absorption, small expansion, toughness, no break when bending.

Mainly used for printing packaging boxes and goods decorative lining paper. In book binding, it is used for binding materials such as paper seals and ridges in hardcover books and hardcover books.

4, letter paper

Letterpress paper is the main paper used when letterpress printing books and magazines are used. The letterpress paper can be divided into four grades of No. 1, No. 2, No. 3 and No. 4 according to the distribution ratio of the paper materials. The number of papers represents the quality of the paper. The larger the number, the worse the paper quality. Paper weight: (49 ~ 60) ± 2 (g / m2); flat paper specifications: 787 × 1092, 850 × 1168, 880 × 1225 (mm × mm); web specifications: width 787, 1092, 1575 (mm There are also some special size papers.
Letterpress paper is mainly used for letterpress printing. The characteristics of this paper are similar to, but not identical to, newsprint. Since the ratio of paper pulp to pulp is better than that of newsprint, the fiber structure of the letterpress paper is relatively uniform, and the gap between the fibers is filled with a certain amount of filler and rubber, and is also bleached, which forms This paper has a good adaptability to printing. It is slightly different from newsprint. Although its ink absorption is not as good as newsprint, it has the characteristics of uniform ink absorption; water resistance and paper whiteness are better than newsprint.
The relief paper has uniform texture, no lint, slight elasticity, opacity, slight water resistance, and certain mechanical strength.
Applicable to important works, scientific books, academic journals, textbooks for colleges and universities, etc.

5, news paper

Newsprint is also called white paper, which is the main paper for newspapers and books. The characteristics of newsprint are: paper is light and light, with good elasticity; good ink absorption performance, which ensures that the ink can be fixed on the paper surface; after the paper is calendered, both sides are smooth and no hair, so that the two sides The print is clear and full; has a certain mechanical strength; good opacity; suitable for high speed rotary printing.

Thinking of the history of the book, paying attention to the readers of modern history in Europe and America, will unexpectedly think of the birth of the printed book by Lucien Febvre and Henri-Jean Martin. These two French chronological historiography The masters show the development of printed books in European countries since the Renaissance. The books are all read, so the development of books is actually far more than printing, even more than paper.
Turning on Martin Lanes’s “The Evolution of the Book”, we have re-adjusted the understanding of the book. The book has played an important role in the history of human development. The form of the book has also evolved. Those who publish, print, and swear Copying, protecting books as a professional, and people inspired by the content of books, there are many things in their lives that are not known to us. Whether in the East or in the Western world, religious groups play an important role, because books originally have a sacred mission of strong religion, and the Christian Bible in English is called the Bible, and its original meaning is “book”, but in ancient times In China, North Korea and Japan, Buddhists also preserve complete religious classics.
Yes, in the classical era, different civilized countries invariably invented various books-related materials. Thousands of years ago, the Egyptians invented papyrus, they monopolized the production of papyrus, did not extend the secret of teaching papyrus, and then exported the papyrus to the entire Mediterranean region, not only in ancient Egypt, but also in ancient Greece and Rome, including historians. Thucydides, the philosophers Plato and Cicero, wrote their works on papyrus. However, the papyrus is produced in a dry climate in Egypt. The environment around some parts of Europe is not conducive to preservation. Therefore, some people have invented the more durable parchment, and the parchment has brought economic benefits to the Romans, so they do not need to rely on the Egyptians. From the competition between papyrus and parchment, we can see that the materials of the book also involve regional economic interests.

For many of our graphic design enthusiasts, there may be a disconnect between the design process and the binding. For graphic designer Kristine Kawakubo, the art of hand-binding is at the heart of the design process from conception to completion. The experiment is Kristine’s exquisite handmade books. The key is because the type and image interact to create a unique piece. Speaking of it is very good, she discussed “when you really experience the entire book making process, you will be inspired by the touch of the material and the structure of the book”, which enhances the understanding of the entire design process.
The design of Kristine’s book is conceptually driven. Her design philosophy stems from the mentor and Dutch graphic design legend Jan van Toorn, who said that “visual communication is an idea, desperately seeking images and other forms of truth in the ocean of rumors.” The Dutch designer is developing key The word is famous for replacing the design conventions of the 1960s, and it pays attention to the meaning of design rather than stylistic expression. His heritage church public questioned the autonomy between customer information and designer vision – forming a skeptical view of the target consumer.
Therefore, Christine describes her work as “anti-aesthetic”, which can be seen in the non-traditional page layout that challenges the concept of book concepts. Christine said: “Anti-Americanism itself is actually an aesthetic, this is a paradox.” Her abstract book design documents the typographical study of “multiple typography, no preconceived” for different topics in each publication.
Fundamentally, Kristine’s books are based on “experimental printing by printing methods.” These books explore the complex structure that makes up a book by using different sized papers and different designs on each page. These pages form a collage that informs the readability of a document that delve into the chain of thoughts in the book. For example, Carnialesque Revellion is inspired by global warming issues.

Konica Minolta’s unrivalled AccurioPress line of hardware lets you tap into self-publishing markets that would once have been unprofitable – or simply not existed at all.

Book publishing used to be a complicated business. As we all know, however, the times – and technologies – are a’ changing. Whereas publishing used to be an offset printing domain, on-demand publishing is now a high-growth sector, letting budding authors everywhere produce books, calendars, magazines or photo albums on demand, even in tiny print runs.

As such, it has become a potentially huge business opportunity for digital print shops. Flexible print providers can benefit from this trend by producing a range of bound documents including books, calendars, magazines, and photo albums. InfoTrends expects the book-printing market to grow by 16.7% over their seven-year forecast period, meaning print volume from book publishing will come to almost 54 billion pages by 2016. In other words, on-demand book publishing is a new business field that’s well worth looking into!

On-demand publishing enables authors to self-publish books, or even “sell first, then print”. The big advantage of on-demand publishing is that it makes even tiny print runs of just one copy possible and profitable – and shortens a book’s time to market. On-demand publishing could prove a lucrative source of new revenue for your business.

But how are you going to squeeze the maximum benefit out of this market? Konica Minolta’s unrivalled AccurioPress line of printing hardware, which incorporates both AccurioPress and bizhub Press product series, offers a wide range of benefits that will let you do just that.
