What is a boutique book? My understanding is that fine books must be practical and collectible, and they must be able to attract readers. In terms of design, the style is unique, practical, and beautiful; printing can be mass-produced; in terms of quality, it must be able to withstand domestic and international printing events. Review. To achieve quality printing and publishing, the overall design, original quality, equipment precision, process technology and other aspects must be closely coordinated with each other.
First, prepress/printing
Principle: Select the appropriate printing method according to the content and use of different products.
1, FM network printing
Features: The density of the image is represented by dot density, without screening; avoiding collision due to screen mesh (known as moiré or rose pattern); and the depth of the dark tone part of the image can be opened.
Disadvantages: The flat screen is less reproducible than the amplitude modulation screen, so it is not suitable for light-colored and smooth images, such as the morning fog, white or light-colored skin or texture-free images.
Applicability: Suitable for products with many margins and high sharpness, such as iron and steel, metal, rock oil paintings, and people with strong hue; suitable for the history of product with more image lines, such as clothing, curtains, etc. Cloth products; products suitable for simulation printing, such as ancient paintings.
The Collection of Qing Ming Shang He Tu was printed on the FM network. Taking into account that the book is a draft, more lines, mainly dark tone, in order to enhance its simulation of metal packaging, it is recommended to use FM network printing
2, high network printing
Features: The delicate and soft tone of the printed picture can fully express the image and detailed place of the picture.
Disadvantages: When using high-line printing, when the dots are enlarged in the printing process, it is easy to form stencils, and highlights and shadows can easily cause the loss of image levels.
Applicability: It is necessary to determine whether to use high-line printing according to the content, use, etc. of the product. It is applicable to high-end products with fine performance and close look, such as pictures, advertisements, and trademarks.
The "Living" book is printed on 300 high-line screens. Most of the text in this book is black and white. The layering of the image cannot be reflected by the change of color. Therefore, high-line printing is used to increase the sense of layering and exquisiteness of the image.
3, high-fidelity printing
Features: Compared with ordinary four colors, its color gamut reproduction range is wider and more vividly reflects natural colors.
Disadvantages: The reorganization of the equipment is very demanding. It requires six or more color printers and requires high printing accuracy. The printing cost is high, such as increased printing plates, increased ink costs, and increased color separation software.
Applicability: It is applicable to high-simulation products, such as copying of calligraphy and paintings, copying alone, etc.; it is applicable to commercial printing of advertisements, such as calendars and product packaging.
The "Excellent Chromatography" book uses high-fidelity six-color printing. The ink used is Hexachrome (high-fidelity six-color) ink.
Second, binding / printing
Principle: to achieve the cooperation of materials and processes, and use various binding and post-printing techniques to achieve the desired results.
1, the process and material cooperation
The cooperation of hot stamping process and shell material: good stamping effect can be obtained on leather, leather-filled materials, paper and plastic surface.
If the surface is rough, the hot stamping is easy to fall off. If the hot stamping type is too small, then it is easy to paste the word. Therefore, the hot stamping should pay attention to the choice of the shell surface material and the size of the hot stamping font.
The gluing process cooperates with the ink: the surface of the metal ink sheet is glued. Due to the characteristics of the metal ink itself, the film separation phenomenon easily occurs after the gluing, so care should be taken to avoid this problem when gluing the surface of the large area metal ink. .
The automatic production of equipment and the cooperation of materials: When producing hardcover books, if the shell fabric is made of leather, the production speed of the machine is fast, the setting time is shorter and the stereotyped effect is not ideal. It is recommended to manually cover or use other fabrics.
2. Application of PUR binding technology
Features: strong adhesion, long storage time; adaptable, can be used in high temperature or low temperature environment; good flexibility, easy to open reading; environmental protection, paper, no VOC (volatile organic matter) production, no pollution surroundings. Books made using PUR glue are easy to read.
Applicability: It has a wide range of applications, and has good fixing power for the printed parts after surface treatment such as UV, varnish, and lamination.
3, application of flocking technology
Features: Vivid image, strong three-dimensional sense, soft touch, bright pattern patterns, flocking is not easy to fall off.
Matters needing attention: paper, rubber surface, leather stuff, leather material suitable for flocking; cloth pattern too deep fabric due to sticky, not suitable for flocking; UV surface is not suitable for flocking, will not stick firmly.
The flowers and text patterns on the cover of the “Floral Decoration Guide” are implemented using flocking technology. Through such processing, the content of the cover and the content is more relevant and more three-dimensional.
4, the application of other technology
Other applications such as punching, partial UV, glitter, glass beads, luminous inks, fragrance inks, wrinkle oils, and matte effects have not been introduced one by one.
Third, the use of materials
Principle: It needs to be selectively used according to material characteristics and product design.
1, the selection of paper
For product education with high print quality requirements, such as catalogs, matte coated paper is generally used (this does not appear to be very dazzling when reading); for ordinary books such as textbooks, etc., the book is generally used (offset paper); Reading materials such as reading materials, generally use Beige book paper, so that it appears to be of high grade; for the copy, copy of famous paintings and other products that require a higher degree of simulation, you can use Xuan paper printing.
2, the choice of cover paper
For high-end hardcover products companies, you can use some leather material to make shell surface (but specifically to determine the choice of fabric according to the content of the product and design style). For mid-range hardcover products, leather or fabrics can be used for shell surfaces. For ordinary hardcover products, coated paper can be used.
3, the use of materials must take into account the practicality of the product
For different products, special materials are selected according to their functions.
"Bicycle Tour Victoria" is printed on synthetic paper. Synthetic paper is characterized by high and low temperature resistance, water resistance, acid and alkali resistance, and abrasion resistance, and is suitable for use in special environments.
4, the use of materials should take into account the environmental protection
As people attach importance to environmental protection, environmental protection printing will become the direction of future printing, such as the use of FSC (Forest Stewardship Council) certified paper, soybean green ink, alcohol-free fountain solution, water-based gloss oil and the introduction of water-based coating technology Wait. "Forest Forest" is printed on FSC paper.
