Graphic designers need to master 8 printing knowledge

In the print design resolution settings must reach 300 pixels / inch, it should be noted that the first to set the size and then set the resolution, otherwise the size of the small, the resolution increased is useless, so in the design before the need to confirm the resolution as well as the size, otherwise the design to get done and then increase the picture will become blurred.

Print design bleed (margins) is generally set to 3mm. print design must take the size of the bleed into account, because the finished product will be printed in the late 2mm-3mm will be cut to ensure that the work of the perfect degree.

Size is not fixed, the specific size in accordance with customer requirements, if the customer does not require in accordance with the traditional size ~

Print design, the color mode needs to be set to CMYK mode, CMYK color mode is used for print image presentation.CMYK is also known as the printing color mode. It is made up of four colors of ink: cyan, magenta, yellow and black, each of which is used from 0% to 100%. Since the three CMY inks do not form a pure black color in printing, a separate black ink K is needed, which results in the formation of CMYK as a color mode. The larger the amount of ink, the heavier and darker the color; conversely, the smaller the amount of ink, the brighter the color.CMYK are 0% is white, 100% is black.

Printing fonts: Nowadays, the fonts commonly used in Chinese character printing are fine bright, Song, italic, line black, etc. When designing printed materials, try to use as little pen as possible. When designing printed materials as little as possible to use the strokes too thin font, too thin font if the font size is too small, often easy to print out, or the font does not look clear. The body of the general use: Song, Book Song, imitation Song first-level title usually use: big black, big standard Song, small standard Song second-level title usually use: Song black, italic, bold print font size: the actual size of the printed text with the size we see on the screen is different. Some designers with insufficient knowledge of printing in order to pursue the layout of the beautiful, in the design of works using too small font size, the actual printing out of the discovery of the inability to see, thought it was the printer's problem, which is the lack of knowledge of the consequences of printing. Printed text by the different changes in large and small, typesetting and image processing software in the measurement of font size of Chinese characters, is currently the main use of printing special font size system and point system. Different printed matter on the size of the font selection is biased, for example, the design of picture books such as more text, the font is recommended that the large title is greater than 3 fonts, sub-title less than 4 fonts, less than 6 fonts within the text, line spacing is generally 1.5 times the distance between the lines. Instructions for printing or album printing text size is recommended not less than 7 font, too small will affect the reading and printing quality.

Lenticular printing: ink expression of about 90%, rich in color tone. Strong color reproduction. Strong plate resistance. Printing quantity is large. The range of paper used is wide, and materials other than paper can also be printed. Generally are used in large quantities of printed matter, such as color magazines and popular building materials printing, etc.

Intaglio printing (cigarette labels, wine labels, instant noodle pockets, sugar paper, etc., high quality printing requirements, printing a large number of printed matter is more commonly used in this way of printing)

Offset lithography (this process is more widely used, the quality of the process is stable, such as newspapers and books, packaging, PVC, stickers)

Offset lithography (this process is more widely used, quality process is stable, such as newspapers and books, packaging, PVC, stickers)

Screen printing (according to the characteristics of printing, can be printed in very small quantities, dozens of sheets can be printed, the shape of the printing plate can be changed

There are many types of printed matter, the use of its requirements and printing methods vary, so designers must be based on the use of the demand for the printing process and the requirements of the characteristics of the paper to be used accordingly. From the use, can be simply divided into commonly used printing paper and art paper (also known as fancy paper), commonly used printing paper contains Dowling paper, book paper, matte powder paper and coated paper, etc., text books use more Dowling paper and book paper, albums use more matte powder paper and coated paper. In the design of a printed work, we must not only consider the image, text, color and other elements of the collocation, but also must consider the design of the work can be printed to achieve. Some graphic designers pay too much attention to the effect and ignore the effect of the landing, due to the printing process, paper materials do not understand, the effect is far from the real thing. Only by understanding some of the knowledge of printing, your work can be perfectly presented in front of everyone's eyes.
