The technology of color reproduction is a specialized knowledge. For a long time, we often talked about the problem of color reproduction in the production process of design printing, and we often talk about color reproduction, RGB, CMYK, pot color, PANTONE, DIC, Toyo And swop and so on are all color unit titles. Many designers use PANTONE, Toyo and other colors to design, on the screen is to use RGB as a display, a variety of colors set for the screen on the bright colors, the screen on the phosphor and inkjet printer out of Paper makes the designer happy, and the artwork reaches the customer's hands. It is full of praise. Everyone hopes that printed products will come out soon. So the designers handed over the archives to the output and production center for color separation output or poster printing, but when the finished products were handed back to the designer, the colors on the screen turned out to be different, and the beautiful flowers turned dull and the mouth-watering food became What happened after a few nights of separation? Most of the original screens and ink-jet printers had a good color rendering capability, exceeding the color gamut of ordinary four-color printing or poster ink jets, so that the original colors could not be represented by these reproduction methods.
What is Hi-Fi Color and its translation
In traditional color printing techniques, yellow, magenta, and indigo (Cyan) can produce thousands of colors, and the addition of black increases the overall concentration, and therefore is more abundant. General color printing equipment, whether it is inkjet, laser toner and heat transfer technology, are using CMYK four-color ink, but in recent years manufacturers have developed more than four-color devices, CMYK plus light red and Light blue, CMYK plus orange and green, more CMYK plus light red, light blue, orange and green, they are using four colors plus more than other ink to enrich the print color, the original is also used in the printing technology The program, this is called Hi-FiColor. Hi-Fi stands for High Fidelity and is highly realistic. Hi-Fi Color is translated into "high-fidelity color" in China, and Hong Kong scholars translate it as "original color."
It is not easy to faithfully reproduce colors with general printing methods because the general four-color and copying techniques have certain limitations. The color gamut range of the copied colors is affected by the printing method, the combination of paper and ink, and a whole The hue picture must be converted into a half-tone picture with halftone dots before it can be printed. These factors greatly weaken the color gamut of the copied color. If the original color is used for copy printing, the original color can be more faithfully expressed.
True colors are not new
The original color is not new. Yu Lan used line blue as the fifth color beyond the four colors to supplement the color of the blue sky and green grass of the landscape picture, and used light red to supplement the human skin color and make the color more abundant. Later, four-color printing technology developed rapidly, basically four colors have already met the needs of most of the color prints. But why did you re-emerge this kind of technology in recent years? It may be the development of science and technology that makes it necessary to have previously experienced color separation masters, the work that can be accomplished through very complicated processes, becomes button-like today, and multi-color printing units are also very popular, plus people The degree of color reproduction, so this technology has again attracted the attention and development of the industry.
In 1993, the United States initiated the Hi-Fi Color research program, which was supported by several manufacturers. Later, different manufacturers introduced different solutions, including companies such as Linotype-Hell, Dupont and PANTONE. After years of development, Many companies in Europe and the United States have already mastered the technology, and others are happy to adopt it. Everyone in Hong Kong knows this technology for some time, but no one really knows it in detail, causing a situation where only a few stairs are ringing and no one comes. I heard that some company orders can not be answered because of lack of experience.
For a long time, colorists have been conducting researches to find out a successful method of color reproduction. In offset printing, they added a layer of color to the general four-color printing and printed it in five colors; another layer of color was used to print in six colors; even seven-color printing. These extra colors, of course, extend the color gamut of the copied color, but what color is appropriate?
In the early days of color separation using a plate-making camera, some art and portrait photos were printed in six colors; in addition to C, M, Y, and K, pink and light blue were added to increase the color of green, purple, and skin. . In experiments and research, special colors such as gray, silver, or gold can be added to C, M, Y, and K, depending on the color characteristics of the original image.
The four major categories of original colors
<I> High Efficiency Color - This is based on the ink of CMYK, using some high-color four-color ink, the advantage is that the general printing and four-color printing floor can be done.
<br>Hyper Color - Developed by Dupont, the company uses CMYK and CMY to enhance color. The same benefits of creating high-performance color are the use of four-color printing buildings.
<3> PANTONE Hexachrome - This method was developed by PANTONE, using six color printing, CMYK plus orange and green, but this set of CMYK and OG ink is Hexachrome's ink, not the general CMYK.
<4> Kuppers Technique - This method uses CMYK and RGB colors for printing. The advantage is that the problem of trapping and Trapping can be reduced. For example, the big red was originally composed of M+Y, but one of the Red lanes can replace MY rain.
The most versatile Hi-Fi Color standard
Hexachrome is one of the original color technologies developed by PANTONE; it was first introduced at the DRUPA exhibition in Germany in 1995. Hexachrome adopts six colors, including improved CMYK and high-saturation orange and oak colors. The use of a six-color print-sleeve printing method can confuse the 90% color of PANTONE PMS, which is more modest than general four-color printing. It is suspected that 50% of the colors are almost double. Current PANTONE products for Hexachrome include HexWare's color separation software, Hexachrome Color Selector, and Solid in Hexachrome's color guide.
Hexachrome separation
Hexachrome technology is the most difficult to master with color separation and proofing technology. There are few tools to choose from. PANTONE has produced a famous piece of Hexware software. The software is divided into two parts - HexImage and HexVector Hexlmage is a Photoshop plug. The -in tool is mainly used to colorize image in RGB or Lab color space into Hexachrome's six-color image. HexVector is Adobe's Plug-in for Illus-trator, which deals with Hexachrome colors in the graphics part.
PANTONE Hexlmage
This is a Photoshop Plug-in tool that can decompose the RGB, CMYK, and Lab files into Hexachrome's CMYK and OG six-sided colors. After separation, they are saved as DCS2.0 files for placement in QuarkXPress, Adobe PageMaker, etc. Or use in a drawing application. Hexlmage uses ICC workflows and contains a variety of ICC profiles. After the image is separated, you can use Photoshop's built-in features to preview the color separation effect of each color version, and you can edit and modify it at will. This part of HexImage is mainly the process of disassembling the image, but the color gamut of the image itself is more effective than the four-color CMYK.
PANTONE HexVector
To use Illustrator's designer's needs for Hexachrome, the ancient three sets of major color libraries include HexachromeCoated, Hexachrome Uncoated, and PANTONE Solidin Hexachrome.
1. Open an RGB image in Photoshop.
2. Use Photoshop's Gamat Warning to observe. The gray part of the figure represents the color that the four-color ink cannot hold.
3. Select the appropriate ICC profile in Hexlmage and press the Separate button to block the RGB color separation.
4. After converting to Hesachrome's file, there will be HexachromeCMYK and OG big color version, save the file as DCS2.0 file format, and then you can add PageMaker, QuarkXpress and other software for typesetting and output.
5. When the Hexachrome image is placed in PageMaker, the color window will automatically appear in the color version of Hexachrome.
6. After installing HexVextor, start Adobe IIIuxtrator and find the HexVector menu in the window. Here you can convert and set the color of Hexachrome.
7. Hexachrome color options are available here, including Hexachrome Coated, Hexachrome Uncoated, and Solid in Hexachrome. The book uses gold east paper 95 grams - large space shuttle
Hexachrom's method of writing
In the case of drafting, it is possible to use traditional inks to print, but using Hexachrome's standard inks is more costly. Another way is to use digital proofing. The Hi-FiJet produced by Roland is a six-color inkjet printer that can be used with PANTONE Hexachrome standard inks. The use of Hi-FiJet to conduct the proof comparison calculation.
All-around color separation software ICISS
The full name of ICISS is Interactive Color Independent Separation Software. The developer of this software is the VISU company in the Netherlands. Two years ago, PANTONE was the general agent of the whole world. Now it has transferred to Special Colour in the United Kingdom. (http://aurelon.iae.nl/dealers/dealer.htm)
ICISS's color separation function is extraordinary, this software is actually a high-end color separation machine (such as Hell, Crossfield, DS), the color computing part (Color Computer), its technology into Mac operating software. ICISS can not only deal with the separation of general four-color inks, the strongest is that any ink color can be input into the software as a spot color, four-color or spot-color four-color mixed color separation, the number of colors is not limited, from two There are no problems with color separations up to sixteen colors.
ICISS software work steps, (l) start the ICISS Scanner software part. (2) Set the color number and color data of the ink, input the data, and (3) perform the Hue Mapping process on the ink color data by setting different ink color curves to restore the color spectrum, and (4) setting the gray balance. (Gray Balance), (5) Set color correction (Color Correction), (6) Save all settings as a component color script, (7) Start the color separation section of ICISSSeparator to perform color separation, and the completed File will be saved DCS2.0 format. When color separation is complete, you can use Adobe Photoshop software, plus VISU's CoCo for color correction work.
In summary, ICISS is an all-around color separation and color correction tool software. It is an incarnation of a high-end Scanner.
1. ICISS Scanner software for different color settings.
2. Hue Maping settings.
3. Gray balance setting.
4. ICISS Separator performs color separation.
5. Open the color separation DCS 2.0 image file in Photoshop, and you will see the Channel of the spot color.
6. Use VISU CoCo's software in Phogoshop for final color correction.

PO shopping bag:
PO is HDPE, By high-pressure polyethylene (PVC raw materials through a hot melt blown out.Po plastic bags is the electronics industry, electrical industry, and watch with more products such as bags.This kind of bag is not transparent, in the absence of additive species before is white, the bag body crisp, good tensile strength. PO material but make it flat pockets, along the bag and the organ bag square bag, handbag, you can add a variety of color to make different colors of bags, mainly to do the inner packing of products, such as a small alarm clock, belts, electronic packaging, etc. Can print recycling mark and warnings. High-pressure polyethylene thin film feel is relatively hard, rub the gentle rustling sound when, transparency is relatively dark. PO plastic bags also has its particularity it can be done very thin thin, according to our current control technology, a SiDou can production come out, and the PE and PP can achieve the thinnest 2 silk, PP is not even, the PO price advantage is more obvious. But the PO plastic bags near white, and USES relatively much smaller. , Po plastic bags non-toxic, feel like wax, has good low temperature resistance (the lowest temperature can reach 70 ~ 100 ℃), chemical stability is good, most of acid and alkali erosion (acid) with characteristics of oxidation resistance, temperature does not dissolve in solvents, small water imbibition, excellent electrical insulation properties; But polyethylene for environmental stress (chemical and mechanical effect) is very sensitive, heat aging. The properties of high density polyethylene owing to the different varieties, mainly depends on the molecular structure and density. Using different production methods can get different density (0.91 ~ 0.96 g/cm3) of the product. Polyethylene available general thermoplastic plastic molding method (see plastic machining).
