Color correction has always been a headache for computer graphics, because some colors on the monitor cannot be printed by UV, or there are serious color differences. If it cannot be corrected at the design stage, it will be too late when the finished product is printed. Color cast problem of RGB to CMYK UV printing uses magenta, cyan, yellow, and black, so the colors are specified by CMYK. As long as CMYK is determined, it means that the proportion of UV ink for printing is determined, and the color will usually not be a big problem (from the general point of view). However, the color in the computer is represented by RGB mode, so to print RGB colors, it is necessary to go through a color conversion step, which will cause two problems: The first problem is that UV ink cannot print all RGB colors. Usually, high-brightness colors, fluorescent colors, and metallic luster cannot be printed, so they have to be replaced by CMYK. If you find that the selected color box has an extra triangular exclamation mark when using Photoshop, or an exclamation mark is added after the CMYK value, it means that the color cannot be printed. The second question is, what conversion standard is used when converting RGB to CMYK? Even if a certain RGB color can be converted to CMYK, it does not mean that the actual color of the UV ink will be the same as the color displayed on the screen. Usually, the

Before talking about the application products, visual effects, printing costs, etc. of four-color printing and spot color printing, let’s first understand the basic printing colors. 1. What is four-color printing? Four-color printing generally refers to the printing process of using yellow, magenta, cyan, and black ink to print various colors of color pattern manuscripts. 2. What is spot color printing? Spot color printing refers to the printing process of using other color inks other than yellow, magenta, cya,n and black ink to print the color of the pattern manuscript, such as green, gray, etc. 3. What products are suitable for four-color printing? Photos taken in the form of color photography that reflect the colorful color changes in nature, colorful art works of painters, or other pictures containing many different colors, will be printed using four-color printing technology for technological requirements or economic benefits. 4. What kind of products will use spot color printing? The pattern itself has high requirements for color, and the color mixed with four colors cannot meet the requirements of the effect, so it is necessary to equip the spot color, which is more to improve the quality of the printed product. 5. What is the difference in the visual effect of the color block of spot color printing and the color block of four-color overprinting? The ink mixed by spot color printing is obtained according to the principle of color material subtractive color mixing. Its color brightness is low and saturation is high. The change of

What are the problems with the direct printing of gold and silver colors? Users often ask how to print gold and silver colors, and whether UV printing can print these two colors. In fact, it is possible, but there are two main problems that cannot be applied. First, the price is too high, and the quantity is small. The price of importing these two UV inks is generally more than USD300/liter, which is not cost-effective. Second, the UV ink particles, after adding silver powder and gold powder, are very large, which can easily clog the head and cause scrap. So, what are the current ways to achieve gold and silver color printing? Hot stamping Hot stamping is to heat and transfer metal to paper. It is a kind of post-printing processing, so it takes one more day of processing time than normal printing. The cost of hot stamping depends on the area of ​​hot stamping. The larger the area, the more expensive it is. Hot stamping is the most shining among many hot stampings. In addition to gold, silver, blue, red, green, purple, black, platinum, etc., they can also be heated and transferred to paper. Printing gold color Gold can be printed with special gold ink. Special colors are colors outside the four colors of CMYK, so when printing, an additional printing plate and printing fees are required for gold. Since printing metallic colors is a special color among special colors, the printing fee is usually 2-3 times more expensive

UV ink is an energy-saving and environmentally friendly ink that can be hardened and attached to the surface of the printed object by UV light (ultraviolet light). It dries at the moment of output, so the production delivery time can be greatly shortened. It can be printed on various non-absorbent materials such as resin, glass, metal, etc. A rich series of inks (soft, core, hard) can be used according to the purpose and material, from small accessories to large plates, architecture, industrial design, all of which can allow the pattern to be printed. One. Low VOC (volatile organic compound) and ozone-free ink After being irradiated by UV light, the pigment is directly attached to the surface of the material and hardened, so almost no VOC is generated. In addition, short-wavelength ultraviolet rays that produce ozone are not used, so it is not only environmentally friendly, but also an environmentally friendly ink that takes into account the health burden of operators. Two. Curing method of UV ink 1. Use LED light source for UV irradiation to solve the problems of halogen lamps, such as: long idle time, high power consumption, large light source size, short service life, high heating temperature, etc. 2. Energy saving and long service life Compared with halogen lamps, the power consumption and heat generation of LEDs during irradiation are greatly reduced. Not only energy saving, but also the life of the bulb has been greatly improved, which is beneficial to reduce waste. 3. Less heat generation, thus

The pattern design before printing is closely linked to UV printing. There are many pattern designs with good design concepts, but they lack knowledge of UV printing technology, and the printed products do not meet the design requirements. In fact, in addition to solid basic skills, good pattern designers also need to master the distinction between four-color printing and spot-color printing, the importance of pre-press proofing, the difference between screen color and printing color, etc. Understanding the UV printing process can not only greatly reduce the risk of errors, but also improve personal job capabilities. 10 precautions for design, processing, and UV printing production before printing: 1. The image must be converted from RGB screen color to CMYK printing four colors. 2. The image must be 300DPI or above, and the format must be TIFF, AI, and other vector formats. 3. Please refer to the four-color manual when selecting colors. 4. The value of any CMYK color should not be less than 8%. 5. When using CMYK, the sum of the four colors should be kept below 200%, because different materials have different ink absorption degrees, reducing the occurrence of difficult drying. 6. When using 100K large color blocks, adding 30C can make the printed black more solid. 7. Make a sample before printing to ensure that the color and content are printed and processed correctly. 8. Different materials have different ink-receiving abilities, which will affect the final printing effect. 9. More processing steps or more complex printing requirements will

Key Advantages: 400mm/s Speed: Uninterrupted motion achieves 2-3x

Compared with traditional silk-screen printing, the process of UV printing has been simplified a lot, but there are still steps such as drawing, retouching, guiding, and setting color curves to complete the whole process. Due to certain technical limitations of different UV printers and environmental factors, the quality of UV-printed products is affected. What are the factors that cause color differences? Objectively speaking, due to various conditions in actual production, color errors cannot be completely eliminated. The only way to control the color quality difference within a reasonable color standard is through adjustment. 1. The color of UV printing is different from that of the computer monitor. The color of UV printing is different from that of the computer monitor. The computer monitor will cause different viewing angles due to different brands, models, and parameters set by individual color values. The display is based on RGB color light, while the printed product is based on CMYK four colors for color adjustment. The principles of the two are very different, which will cause serious color differences between the screen display color and the printed product. Never use the screen color to calibrate the color. 2. UV printing environmental factors. Environmental factors will also affect the difference in printing color, such as printing time, UV ink quality, temperature, humidity, material characteristics, etc. Factors that cannot be controlled by humans will also affect the difference in printing color. Some customers like to be greedy for small bargains and buy cheap inks, which leads

What is CMYK printing? CMYK is also called printing color mode. The biggest difference between it and RGB is that RGB mode is a luminous color mode, and you can still see the content on the screen in a dark room. CMYK is a color mode that relies on reflection. Why can we read the content of newspapers? It is because the sun or light shines on the newspaper and then reflects the content to our eyes. CMYK can only be seen under the condition of the external light source. So it cannot be read in a dark room. As long as the image seen on the printed matter is expressed in CMYK mode. For example, journals, magazines, newspapers, brochures, etc., all use CMYK mode. CMY is the first letter of the names of three printing inks: Cyan, Magenta, and Yellow. K is the last letter of black, and K is used to avoid confusion with blue. In theory, only three inks, CMY, are enough. Adding CMY together should get black. However, high-purity inks cannot be achieved for the time being, and the result of adding CMY is dark red. Therefore, in order to ensure the output of black, a special black ink needs to be added to blend. What is RGB printing? RGB is generally called the [three primary colors of color light], R (red), G (green), and B (blue). The color scale of RGB is 0-255. Since RGB is color light, the superposition of colors is brighter and
