Analysis of the Trend of Differential Printing

Excellent 6 color printing

At this point, it is clearly shown that the tone and color saturation of the six-color printing are superior to the four-color plate printing. But be careful with skin color. In the case of 4-color printing, the skin tone is reproduced by the screening of magenta and yellow. In the case of 6-color printing, because of the increase in the number of orange screens, the distribution of dots displayed by each color becomes complicated. Although the color saturation level is improved, the level changes easily and the skin color collapse phenomenon occurs. Therefore, in the prepress project, it should be carefully handled. This may be the deficiency of the 6-color printing.

In general, the charm of the 6-color printing + 230 line screening is still greater than the four-color plate. Only ink costs more than 4-color printing, and the charged price is 1.5 times that of 4-color printing. Since 6-color printing has a good differential effect and can obtain high added value, it is easy to establish a good relationship with customers. Personal relationships.

Because Japan's printing market is currently unable to take on 6-color printing, there are not enough companies, and often encounter a large amount of cosmetics on the market, delivery time is short, when a company can not accomplish the task, you have to contact the same Several companies to help complete. To this end, the "6-color Printing Confederation" has been established in various parts of Japan. Whenever an urgent task is encountered, they assist each other in solving problems, thereby gaining a high degree of trust in the market.

III. Adding value with water-based bright oil

In the printing market in Germany and Japan, the use of water-based brightening oils can create added value and differentiated effects.

1. Use 2 kinds of light oil to obtain contrast

After the production practice, both the water-based gloss gloss oil and the OP gloss gloss oil can express the contrast between gloss and dullness. The practice is to apply OP on top of 4-color printing.

Matte oil, coated with water-based gloss polish, dried with infrared, OP

The lubricated part of the lubricated oil is repelled and becomes finely particulate, constituting a matte tone, and the part without the OP brightening oil becomes a glossy tone, thereby presenting a contrast.

According to the use, it is possible to simply obtain a matt and glossy contrast effect without using a flexographic plate making. Due to the use of aqueous bright oils based on acrylic resins, environmentally friendly materials can be used. In addition, the use of water-based brightening oil makes it easy to recycle paper. With one-pass printing, the cost is reduced and the delivery time is short. Today Heidelberger has introduced a six-color printing press with an aqueous special light coater.

2. Add 1 color to get metallic color

Many printing companies have put silver on top of 4-color printing ink to obtain metallic color performance. The approach is silver + 4 color + water-based brightening oil, because no longer need a plurality of metallic colors, there is no need to increase the printing unit and ink replacement procedures, eliminating many restrictions. In addition, with the water-based brightening oil, it can both protect the surface and give the paper a glossy appearance. If you take one pass, you can immediately judge the color match.
