"Coated paper directly inkjet printing!", The printing industry looks forward to ten years. Today, "JETALL® water-based universal pigment ink" was finally born. At the 2nd Guangdong International Printing Technology Exhibition, Zhengzhou Hongsheng Digital Technology Co., Ltd. perfectly displayed "JETALL® water-based universal pigment ink" and coated paper printing. The application program has won praise from many printing professionals. "Coated paper is directly inkjet printed!" It is like a strong light that cuts through the night sky, instantly transforming into millions of dazzling colors, illuminating the earth and the direction of the digital printing industry.
"Direct inkjet printing on coated paper!" Why is it so anticipated and welcomed?
First of all, from the current status of the printing industry. Most graphic companies, export companies, and printing plants mainly print on ordinary digital paper or copperplate paper. Coated paper, as the most widely used paper in the printing industry, is in great demand. In the past, it was not printed on coated paper because it was impossible, and it was because of last resort. Otherwise, there will be no imitation coated paper. Compared with ordinary digital paper and imitation coated paper, what are the advantages of printing directly on coated paper?
1. Cost saving. At present, the coated paper used for printing is calculated at 7,000 yuan per ton, converted to 200 grams of A4 format. The cost of a single sheet of paper is about 0.1 yuan per sheet. 190 grams of A4 format digital proofing paper or imitation coated paper is commonly used, and the cost of a single sheet of paper is 0.6 yuan / Sheet or more.
2. From a functional point of view, it can be printed directly on coated paper, which is easy to solve the problem of "following color" in digital proofing, because the proofing paper is exactly the same as the printing paper.
3. Coated paper is widely used, "coated paper directly inkjet printing!" Solves the problem of printing media, and also brings a broader market for short-run printing.
Second, from the application market of coated paper in the printing industry. Coated paper is often used to print pictorials, advertisements, landscape paintings, calendars, high-end books and other printed materials, and has great potential for application in tenders, recipes, business cards, cards, product manuals, sample books, short-version books and so on. Coated paper is smooth and smooth, with high smoothness and good gloss. It is used for color printing with the characteristics of clear image, bright color and high saturation, so it is widely used in short-run printing and digital proofing. Short-run printing is widely used to meet personalized printing and to comply with the trend of the times and the trend of digital technology development. Digital proofing reflects the advantages of small equipment and use cost, easy operation, easy to "follow color", and large-format printing. It is gradually replacing the traditional proofing and laser printer proofing positions, and the market prospect is promising. At present, coated paper is also used more and more in the office field. Compared with special photo paper, coated paper is much cheaper, which can greatly reduce the cost of color printing paper.
Judging from the development trend of the printing industry, digital operation is the trend and will become the mainstream. On the one hand, it saves intermediate links, avoids the increase of equipment investment and labor cost, and improves work efficiency. On the other hand, the operation is simple and convenient, highlighting the personalized service, and it can be printed at any time, with the changes and printing.

"Coated paper direct inkjet printing!" Since it is so popular, why should the industry wait for ten years? What are the technical difficulties that need to be resolved?
First, analyze the coated paper. Most of the coated paper is not designed for inkjet inks. It has excellent affinity for printing inks, but it has poor adsorption capacity for printing inks. When using dye inks Phenomenon such as scattered ink and ink flow often occur, and the use of pigment ink is prone to pile up.
By changing the characteristics of the ink, the ink becomes easy to be absorbed by coated paper like printing ink, so as to improve the effect of printing on coated paper by inkjet printers. This is of course the most easily thought of solution, but this solution It is very difficult to achieve. It is difficult to achieve the water-based environmentally friendly ink with the same affinity as ink on coated paper and at the same time to ensure that the print head smoothly discharges ink, under the previous technical conditions. But now the ink of Hongsheng Digital Technology Co., Ltd. has done it!
How does "Hongsheng Digital" achieve "direct inkjet printing on coated paper!"? Our plan is like this.
Relying on the strong strength of ink research and development, Zhengzhou Hongsheng Digital Technology Co., Ltd. launched "JETALL® water-based universal pigment ink", and with the advanced constant temperature heating method, the high-speed jet of ink droplets instantly solidified on uncoated copperplate paper to The image is shaped faster and the colors are more vivid and realistic. This solution is specifically "JETALL® water-based universal pigment ink + printer with modified heating device + ordinary coated paper", and its core is JETALL® water-based universal pigment ink. Because JETALL® water-based universal pigment ink has good adhesion on the surface of coated paper, it can be perfectly presented in terms of color and gloss, and has good rubbing fastness. The JETALL® water-based universal pigment ink reflects the environmental protection theme from the production link, does not contain volatile solvent components, and ensures the health of the operator and the surrounding people. It is also because it is "water-based", and it is also suitable for printer nozzles. Played a certain role of care, extended the life of the printer.
Specifically, JETALL® water-based universal pigment ink has the following advantages:
1. Ink characteristics: Hongsheng JETALL® digital proofing ink belongs to water-based nano-pigment type ink; high saturation, high stability, high color reproduction; has excellent performance of waterproof and moisture proof, non-fading, quick-drying, permanent storage, set various High-tech in one, care for the nozzle, stable and smooth, to meet the demanding requirements of digital proofing professional.
2. It can print all the paper used for printing, especially gold and silver cardboard, even including PVC film, PE film and other media. Since then, no special proofing paper is needed.
3. Compared with other heating methods, the printing temperature can be reduced to about 40 degrees to print, reducing a series of problems caused by excessive temperature to the printer, making the application and maintenance more convenient and worry-free.
4. Thin paper can be printed. Such as 128 grams of coated paper, you can set the printing temperature 35 degrees to print, to avoid paper curling.
5. Wide color gamut and high color saturation. Solve the problem of insufficient color saturation and narrow color gamut of other brands of pigment ink. This product is specially designed for digital proofing, with a wide range of color gamut performance, which can solve the problem of "not enough color" and the "following color" between printed digital proofing and printed products and computer screens.
6. The ink is quick-drying, which is convenient for printing and color management. But it will not cause the nozzle to be blocked easily because it dries too quickly.
7. Water-based environmental protection, care for the spray head, lower comprehensive cost, no worries.

Compared with traditional printing and other printing methods on the market, what are the advantages of the coated paper printing solution introduced by Hongsheng Digital?
First of all, the traditional printing method is difficult to achieve short-run printing of dozens of copies. As for digital proofing, traditional printing proofing equipment has high use cost, slow speed, and complicated links. At the same time, it needs to make a plate before proofing.
Secondly, using laser printing or electronic ink printing, the maximum printing size is limited to A3 +, there is no way to print full-open and folio paper, and it is difficult to "follow color", and the cost of equipment and consumables is relatively high.
There is also the use of weak solvent inkjet ink to print coated paper, which has occupied a certain market in the past.
The advantages of JETALL® water-based universal pigment ink compared to weak solvent ink are: 1. green and environmentally friendly, care for the nozzle; 2. no solvent components, non-toxic, harmless, and non-irritating odor; 3. colorful, saturated high.
Through the early understanding of the market of some customers, the overall evaluation of Hongsheng's "coated paper printing solution" is: simple, practical, and high return on investment, which is very suitable for the traditional printing industry.
I believe that the application of water-based universal pigments will greatly promote the green process of coated paper printing and inject new vitality into the traditional printing industry. Hongsheng Digital is willing to work with colleagues from all walks of life to make unremitting efforts for the prosperity of inkjet.
