The Printing Press has published the lithographic dot printing "color table" since 1977. It has been reprinted and revised many times. The seventh edition was originally printed in July 2011, but it is waiting for the parent company to develop a new color printing company. Heidelberg CD 102 printing machine was officially printed after the adjustment was completed in December, and quoted the most advanced and commonly used ink, paper, blanket, CTP printing plate and wet printing method to maintain high standard and stable printing effect. That is, the "high standard condition" printing that can be pursued in the market can meet the printing production conditions in Taiwan or the surrounding area, and serve as an important basis for color reproduction of color reproduction. After printing, each batch of printed products is measured one by one, and the bindings are printed within the error value indicated on the inside of the back cover. When printing, although the time and space and some conditions are not exactly the same, the materials are also Some changes, but the printed "color table" color and the old version can be very similar.
The publishing house entrusted the "color table" printed by Xingtai Color Printing Co., Ltd., and the work of color printing in Xingtai is as thin as ice. The concentration error on weekdays is acceptable to the extent of 0.07~0.1, but it can only be 0.04~0.07. It is produced within a narrow margin error value. Therefore, it is not necessary to use too many concentration meters. It can be printed only by visual sensing. Now the concentration meter must not leave the hand, and the key step-by-step measurement from right to left is carried out within the scope of use. Printing, because the new printing machine is very sharp and slender on the ink control, it is more stable than all the previous printing machines (the ink control is more than 30 years ago, the ink control method is screwed, and the data remote control cannot be used). I believe this new version The color dot color table will be more stable and the concentration is correct.
Nowadays, there are many people in the developed era of electronic media. They think that they still use the printing dot "color table" as the standard printed matter, especially in the printing mode of the version is becoming weak. But today everyone talks about digital technology. I don’t know the electronic files stored in computer memory, hard disk, USB, CD-ROM, which are invisible and intangible to us, that is, they cannot perceive color CMYK, RGB values, only The interface with humans is the fixed print of printed matter, as well as the screen, display or color display that can be curled. But everyone knows that when you buy clothes, accessories, and other items that are more important to color, if you use different screens, When the display is color-determined, there will be a big gap. Even with the same screen and display, there is still a considerable color difference. These color-related merchandise purchases must return to the color of the printed matter, although not too far away, especially the precise color control printing conditions are more important. When all the electronic toner imaging, electronic ink and inkjet digital printing, also use CMYK four-color dot and density, when the effect of lithography is close, it also shows that lithography is the standard of four-color printing. Under an environmental condition, our color dot "color table" is the standard in the standard, which can be used as a key basis for the designer, prepress and CTP plate output, and the printing effect of the printing machine.
In today's era of digital design, there are many designers or print users who misidentify the color of the pre-press color image or color network reproduction. The color of the image or color block seen on the computer screen will be printed in the future. The color of the print will be the same as the computer screen. This is an unrealistic idea. Because you want WYSIWYG, you have to adjust the color of the screen to be similar to the color table, so that the screen can be similar in print. The color, otherwise only return to the image percentage dot value, and the same percentage color of the color table to make an approximate comparison, feel the color of the printed matter in the future. Sometimes the dot value of the percent carry is not a 10 integer carry on the color table, so you can only imagine the color reproduction value of the middle value between two or more grids on the color table. That is, when lithographic printing is used for a large number of copying methods, even when printing in a small amount of digital color, as long as the printing conditions conform to the color reproducibility of the color table, the possible color reproduction of the colors in the color table can be expected to be reproduced in the future. color. When a lot of colors really match the product, there is often a command button on the website, "Please send me a print catalogue", which means that the print is the medium with the closest color similarity to the actual product. Because the printing company must accept that customers often take garments, textiles, curtains, underwear or other color samples, the color required to be printed must match the "product color", which also proves the color reproduction by the reflective subtractive method, its color density, Although the color gamut is not as wide and high as the screen, the color of the screen is not correct, and it is not similar to the fabric and furniture products of the subtractive method, and the ambient light source has more influence on the color reproduction.
The new version of the color table maintains the original inner page size, double the color of the high turbidity color than the old version, and the number of colors is up to 13,834 colors. It also retains the creative neutral color reproduction of the PCR for many years to reduce the CMY colors in the turbid color. The percentage of dot gain is not only easier to print with black dots, but also the color reproduction is more accurate. It can reduce the problem that the same color spectrum or color change is not similar under different light sources. However, in server interpretation, there must be The PCR control software or plug-in can perform the color replacement reproduction of this PCR. In addition, it can be seen in the future packaging printing, even in high-grade tissue printing, the use of water-based glazing, not only can increase the gloss of the print, and the ink color is also more thick, with better color performance, plus easy to dry immediately Dip back. Therefore, the color dot coloring table with water-based glazing is printed in order to meet the needs of all walks of life, and there is a great improvement in the way of nailing. The hard-shell magnetic interlaced bookbinding design is adopted, and the loose-leaf binding can be freely taken out. The page or a few pages of color table texts are compared, hope to help everyone in the convenience of use.
