Retail Hinged Lid Cigarette Box Printing knowledge: printing color and prepress design experience

Printed matter adorns people's life and adds brilliant color to people's life. So what are the characteristics of a qualified print? What should we pay attention to in the printing process? Below, are some of the more difficult to print color and some design experience before printing, let's have a look.

1, gray balance, according to theory and production practice experience, print is the most difficult to control the color is gray balance. Gray balance is in a certain printing suitability, yellow, magenta, green three color plate from light to deep according to a certain dot ratio combination of overprinting to obtain different brightness of the achromatic (white, light gray, gray, dark gray, black), that is, to get the color of visual neutral gray, there are many factors affecting the printing use of ink, paper, full plate concentration, dot area, overprinting and screen line number. Will have a myriad of effects on the gray balance, which is the most test of the overprinting accuracy of the machine and the skill level of the operator.

2, 4 color over screen and 3 color over screen, full plate color do not print (recommended to use spot color printing).

3. People who don't know how to print design things that are hardest to print. Color is on the one hand, too many multicolor pole-line thin, minimal word transparent white, etc.

4, C=50M=50Y=50K=50 large flat network, a little inaccurate color is serious.

5. Four-color text, that is, the four colors of cmyk have text, especially small words, it is difficult to put on, and it has high requirements on the paper teeth of the machine. This is also a more common problem, so the pre-press designer output must check the publication document before the black text, especially the small print, is not only on the black edition, and should not appear on the other tricolor edition. If it appears, the quality of the printed product will be greatly reduced. When RGB graphics are converted to CMYK graphics, the black text will definitely change to four-color black. Unless otherwise specified, it must be processed.

6, there is also the black base is not easy to deal with. Black bottom in order to achieve the effect can use extra black ink or printing twice, it is not difficult to print, more laborious.

7, several color dot superposition, especially more than 70% dot. Specifically, dark brown, coffee, dark green (flat network, containing blue 70), dark blue, purple blue, etc. are difficult to find balance on the printing machine due to the existence of color difference, so they are difficult to print color.

8, printing in general full plate things, spot color full plate or larger area, anti-white characters, the same logo, and the same color block, generally difficult to follow the color, easy to produce color difference, ghost, dirt, scratch phenomenon.

In short, qualified printed matter must meet: first, overprint accuracy; Two, the ink color is uniform; Three, full dot; Iv. Balance of ink painting; Five, printing without printing faults, such as dirt, scratch, flower plate, paste plate, etc. 6. Be strictly faithful to the original manuscript. Printing enterprises must pursue high-quality prints to adapt to people's increasing aesthetic concepts.
