Multi-color ink to build a three-dimensional high-fidelity printing for a wide range of applications takes time

Guide: For commercial printing of advertising, the use of high-fidelity printing will leave a deeper impression on people and improve the effectiveness of publicity. In addition, calendars that require high quality and long-term enjoyment of prints, as well as the printing of merchandise packaging and decoration materials, have a greater demand for high-fidelity printing.

The color characteristics of high-fidelity printing There are two main points about the color characteristics of high-fidelity printing.

The printing color space is enlarged, adding brighter and more vivid colors, so that the printed matter looks closer to the color of the real scene. Second, the linearity of the printed color is different from the conventional four-color printing, and the visual perception is closer to the spectral color. The effect of the change, the print layering is more realistic, and the stereoscopic effect is stronger.

In foreign countries, high-fidelity printing has been applied in commercial printing, and as a development direction of sheetfed offset printing, its market prospects are promising.

Japanese printing technology is known for its high quality and fine printing. In the field of multi-color printing, printing equipment of 8 colors or more has entered the Japanese market. The format is mostly off, and some even up to 10 colors and 12 colors. At the same time, 8-color A2 format and 6-color A3 format printing machines have also entered the market. In addition, 5-color double-sided presses have also appeared in commercial printing, but from a cost-saving point of view, product development will focus on web presses.

Research Status of High-Fidelity Printing With the continuous improvement of people's requirements for printing quality, high-fidelity printing technology with added value will gradually become practical and commercialized, bringing benefits to printing companies.

In four-color printing, four colors of C, M, Y, and K inks are used for printing. In theory, it is enough to use C, M, and Y three-color inks. But in fact, due to various reasons of the process, it is also necessary to increase black ink. Similarly, the secondary colors in which the two basic colors are superimposed are also unsatisfactory, and it is necessary to add a secondary color spot color ink. High fidelity printing was produced under the premise of this theory. High-fidelity printing technology is relatively four-color printing technology, that is, adding several spot color printing based on four-color printing to expand the color expression ability of printed matter.

But just coloring the colors of nature is not enough. One of the purposes of making prints in six-color, seven-color, and eight-color high-fidelity colors is to expand the range of color reproduction and more realistically reflect nature. Since the prints using more than four colors for color separation printing cannot be reproduced by conventional four-color separation technology, this technology has a special status in high value-added prints.

The cost of high-fidelity printing involves high-fidelity printing, which increases production costs and requires high technical requirements for production processes.

If you want to use more plates and inks, it costs more than four-color printing. In addition, there are some factors that limit high-fidelity printing to replace traditional four-color printing, such as the widespread use of multi-color printing presses, the cost of adding film, plates, proofing, and ink.

From the current market point of view, there are many prints suitable for high-fidelity printing. For example, high-fidelity printing with high-definition prints and high-reliability on the quality of reproduction and reproduction can accurately and vividly restore the effect of famous paintings and prevent their shape and color. Distortion, maintain color and artistic charm, enhance the appreciation and collection value. In addition, creating effective color separations and combining high-fidelity pages is also an important factor limiting the popularity of technology. The use of high fidelity technology requires the addition of color separation software. High-fidelity technology also increases the requirements for pressability, generally requiring more printing units or requiring multiple presses.

At present, high-fidelity printing is still in the research and experimental stage in China, and is not widely used in commercial printing, but this does not mean that there is no market for high-fidelity printing. With the continuous improvement of people's requirements for printing quality, high-fidelity printing technology with added value will gradually become practical and commercialized, bringing benefits to printing companies.
