Before figuring out the problem, let's take a look at what a spot color is. In theory, if the three complementary colors of cyan, magenta, and yellow are mixed, the result should be black. But in fact, people can not find the ideal color material, so people ’s color printing, with a black pigment, that is k, here does not use the first letter of black, it is said that it is not easy to be confused with blue and blue. The color system of cmyk constitutes the basic color of our printing. However, the color performance of CMYK's colorants is generally average, so for inkjet photo printing that requires high color expression, the top products have light tones or add other colors, such as orange, red, etc., to enhance the color. Expressive. However, laser printing is different. Laser printing is mainly based on commercial documents, and there is no need to consider too many issues of color expression. However, the entire cmyk color system has a big premise: it must be printed on white paper, and the white space should be left blank. However, we often do not print on white paper, and the trick of leaving white is not very easy to use. For example, on kraft paper, the color of the paper left is not good-looking. White toner can just solve this problem, so white toner is still very practical. But the driver may have to be specially developed, at least let the user choose whether to use white or transparent toner in the output. In the traditional printing field, spot color is a very common thing, especially in the field of printing and packaging, which has special requirements for color. Many times, there are more than one spot color, but many. At the Beijing Printing Exhibition last year, the author reported on the multi-color printing presses of some printing equipment companies. Do printers, especially commercial printers, now also spot color printing? But think about it, this thing is not reliable. Because the premise of spot color output is volume demand, ink and color companies must have enough volume to develop a spot color, and commercial output will not generate such a large demand for a particular color, which is related to Packaging and printing are essentially different, and there are printing requirements for spot colors. When designing trademarks, companies will also choose a color within the cmyk desires wisely. On the other hand, printing relies on ink, and commercial printing is still relying on toner sublimation and fixing. Many spot colors are not common color materials themselves, and it is unknown whether they can accept high temperatures and sublimate with wax. Another cruel fact is that in addition to the United States and Japan, the proportion of color laser printing equipment in other regions is also very low. Everyone is still engaged in black and white aggressive, spot colors? Play for those in need. It can be said that if it is spot color printing, then at present, white and transparent colors are basically over, there will be no special colors, printing companies engage in spot color competitions, and even six-color and multi-color laser printing equipment, that is not In this area, things to consider in recent years. In contrast, the four-color color laser can have a 30% or 40% market share, and they will be happier.

<p> Recently, Oki released two color laser printers in China.
