Precautions for the most popular high fidelity col

During high fidelity color printing, attention should be paid to avoid the possible occurrence of pores in the sheath due to the effect of moisture (or moisture surrounding the cushion)

Agfa, DuPont, Fuji and transcal are the main proofing systems supporting the hexachrome system. Hexachrome output can be simulated by digital proofing The color gamut of some digital color output devices exceeds and shows a personalized trend, which is 50% of the traditional color gamut. For example, the color gamut of scitex

lris's proofing system contains almost all the color gamut of hexachrome. Using it, you can get a satisfactory digital proofing of high fidelity colors. Epson

stylus5000 is also available "The characteristics of reduction, reuse and resource utilization throughout the life cycle of steel structure buildings are used for hexachrome proofing. These printers can enable designers to get the desired effect, and they can generate ICC

profile files for printing. The generation of profile is very important for generating good hexachrome color separation. When using hexwrench color separation, upstream enterprises are required in the

compliance statement of the target equipment What are the restricted material profiles of raw materials and additives that the industry passes to downstream enterprises. This is the only way to compensate for point expansion. When using colortron or spectronllne colorimeter to measure color patches, a profile file is generated and combined with the same data in pro file. When QuarkXPress and other hexachrome compatible software are separating colors, profiles requires that color management be directly added to the application

printing considerations

- when referring to high fidelity color, the first thought is the random addition technology of six color printing. With the formation of random addition technology, many printing workers believe that it is the preferred technology for high fidelity printing, but it is not the case

hexachrome has repeatedly stressed that in traditional Jiashan, orange and cyan can use the same angle, and green and magenta can use the same angle, so as to avoid moire

another concern is how to limit the overall ink volume. Printing an ink film with a total ink volume of 600% may cause problems in paper stripping, drying and many other aspects. This is the weakness of hexachrome. In the hexwrench plug-in, the black version correction is the only place where the total ink volume can be controlled. One advantage of hexachrome is that the color is easy to correct in printing. For example, printing operators can increase the green content by increasing the amount of green ink when copying lush forests. This is much easier than adding cyan and yellow. If you change only one color, you don't have to worry about the change of gray balance of the image

standard color inks in traditional color printing cannot be used in hexachrome. Pantone has developed a set of special inks specially used in hexachrome system, so as to completely get a wide color gamut. Pantone research and development experts found high purity inks through experiments. Through testing, fluorescence and traditional pigments are combined, and a suitable formula is found. For example, hexachrome yellow is composed of traditional diaryl yellow pigments and fluorescent pigments. The optical rotation resistance of this yellow ink is more than twice that of the corresponding traditional ink. Hexachrome magenta is based on Ruby pigment, which is also composed of fluorescent pigment. Green did not add fluorescent pigments, but through reprocessing to improve its purity, its purity increased by as much as 20%. Neither green nor black added fluorescent pigments. The ink with fluorescent pigments is much brighter than the usual primary color ink

regardless of the relative ease of operation provided by this system to the desktop publishing system,

hexachrome may better represent the progress in ink improvement. The important innovation in ink enables printers to increase the color gamut as long as they use the improved CMYK ink. For six color printing, it is recommended that the color hall be black, cyan, green, magenta, yellow and orange

controversy about high fidelity in industrial production, some people believe that hexachrome and other high fidelity color systems are not commercially viable A common view is that compared with the past, modern printing can use some efficient solutions to print very good color images. Choosing six color printing means changing the workflow, and the increase in the number of printing colors will lead to an increase in printing time. Using some current technologies, such as random dot and waterless offset printing, can already meet the current printing. If a magazine chooses high fidelity color printing, it will increase the cost by 20%

other people in the printing industry believe that the market has always been in demand for high-quality prints. For example, publishers in the educational sector have begun to use textbook covers printed with high fidelity technology. The bright pattern on the cover will attract the attention of children and teenagers Some printing customers use high fidelity printing to reduce costs. For example, customers who need to print with many spot colors can save costs by using high fidelity colors. According to Pantone, another economic advantage of high fidelity color printing is that when purchasing paper, high-quality prints can still be printed on paper with relatively low price and low grade due to the bright colors of high fidelity color
