Cigar Paper Boxes are the most difficult to print color and printing design points

Printed matter adorns our life, has added the gorgeous color for our life. So what are the characteristics of qualified printed matter? The popularity of printing is very wide, and there are many problems that need to be paid attention to. Today, we will focus on what kind of color is the most difficult to print, and what elements should be paid attention to when designing.

The first is the grey balance. According to the theory and the experience of production practice, the most difficult color to control is the grey balance. Gray balance is under a certain printing adaptability, yellow, magenta, green three primary color plate from light to deep according to a certain dot proportion combination of decolour to obtain different brightness (white, light gray, gray, dark gray, black), that is to get the visual neutral gray color, many factors affect it, printing ink, paper, full plate concentration, dot area, overprint and screen line number, Will have a inextricable impact on the grey balance, which is the most test of the machine overprinting accuracy and the skill level of the operator.

This is followed by the superposition of several color dot, especially more than 70% dot. Specifically, dark brown, coffee, dark green (flat screen, containing blue 70), dark blue, purple blue and so on due to the existence of color difference, it is difficult to find a balance on the printing machine, so it is difficult to print colors.

Again more difficult to print is the four color stack of empty words. Too many multi-color polar lines are thin and very small word penetration is difficult to print, which requires extremely high paper teeth of the machine. This is also a relatively common problem, so the pre-print designer must check the black text in the publication document before output, especially small text, is not only on the black version, and should not appear on the other three-color version. If it appears, the printed finished product quality will be greatly discounted, RGB graphics to CMYK graphics, black text will certainly become four color black. Unless otherwise specified, it must be processed.

Finally, printing in general full version of things, spot color full version 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, rub, scratch phenomenon.

In short, qualified printed matter must meet: one, accurate overprinting; Two, uniform ink; Three, the network is full; Iv. Balance of ink and wash; 5. No printing faults, such as rubbing, scratches, flower plates, paste plates, etc. 6. Be strictly faithful to the original manuscript. We must pursue high quality prints to adapt to people's increasing aesthetic ideas.
