1. Resolution
In print design, the resolution setting must reach 300 pixels/inch, it should be noted that to set the size and then set the resolution, otherwise the size is small, the resolution is increased and it is useless, so it is necessary to confirm the resolution and size before the design, otherwise the design is completed and then increase the picture will become blurred.
2. The bleeding
The bleeding (page margin) is generally set to 3mm when printing is designed. Print design must take the size of the bleeding into account, because the printed product in the later stage will have 2mm-3mm will be cut, to ensure the perfection of the work.
3.Printing color
Print design, the color mode should be set to CMYK mode, CMYK color mode for print image presentation.
CMYK is also known as Print Color Mode. It is composed of four colors of ink: green, product, yellow and black, and the amount of each ink ranges from 0% to 100%. Since the three kinds of ink of CMY cannot form pure black in printing, a separate black ink K is needed, thus forming the color mode of CMYK. The greater the amount of ink, the heavier the color, the darker; On the contrary, the less ink, the brighter the color. CMYK is 0% white and 100% black.
4. Font and size
Printing fonts: Now commonly used Chinese characters printing fonts are fine, song style, regular script, line boldface and so on. When designing printed matter, try not to use too thin fonts, too thin fonts if the size is too small, often easy to print out, or the font does not look clear.
The text is generally used: Song Dynasty, Song Dynasty, Song Dynasty first level title is usually used: big black, big standard Song, small standard Song second level title is usually used: Song black, italics, boldface
Size: The actual size of printed text differs from the size we see on the screen. Some designers with insufficient printing knowledge, in order to pursue beautiful layout, use too small font size when designing works, and find that the actual printing is not clear, thinking that it is the problem of printing factory. This is the consequence caused by the lack of printing knowledge.
Printing characters vary from large to small, and the measurement of font size of Chinese characters in typesetting and image processing software is mainly based on the number system and point system for printing.
Different printed matter on the size of the font selection, for example, in the case of picture album design, such as more text, it is recommended that the font title is greater than 3 font, the small title is less than 4 font, the text is less than 6 font, the line space is generally 1.5 times the line space.
It is recommended that the text size of manual printing or picture album printing is not less than 7 point font, too small will affect the reading and printing quality.
5. Printing method
Relief printing: The principle of relief printing is simple. In relief printing, the ink feeder of the press distributes the ink evenly and then transfers the ink to the plate by means of an ink roller.
Intaglio printing: As a printing process, intaglio printing occupies an extremely important position in the field of printing packaging and graphic publication due to its advantages of thick ink layer, bright color, high saturation, high printing plate resistance, stable printing quality and fast printing speed.
Offset printing: Same meaning as "lithography" and "offset printing". In this printing method, the ink on the adhesive surface is transferred to the paper surface by means of a roller type colloidal impression. Because the rubber surface is flat, there is no concave pattern, so the pattern and pattern printed on the paper surface are also flat, there is no three-dimensional sense, poor security.
Screen printing: printing based on the basic principle that the graphic part of screen printing plate is ink-permeable through the mesh and the non-graphic part is ink-permeable through the mesh. When printing, ink is poured on one side of the screen plate, and the ink is extruded from the mesh of the text and text part to the substrate by scraping the scraper.
6. Print paper
There are many kinds of printed matter, and the requirements for its use and printing methods are different, so designers must choose the corresponding paper according to the requirements and characteristics of the use of the printing process and the requirements.
In terms of use, it can be simply divided into common printing paper and art paper (also known as fancy paper). Common printing paper includes Taoist paper, book paper, dumb paper and coated paper, etc. Taoist paper and book paper are mostly used in text books, and dumb paper and coated paper are mostly used in picture albums.
When designing a printed work, we should not only consider the collocation of image, text, color and other elements, but also must consider whether the designed work can be realized by printing.
Some graphic designers pay too much attention to the effect and ignore the effect of the landing, because of the printing process, paper material do not understand, the effect and the real thing is far from. Only by understanding some knowledge of printing, can your work be perfectly presented in front of everyone.
