The direct inkjet printing of coated paper has been expected by the printing industry for 10 years. Today, Zhengzhou Hongsheng JETALL water-based universal ink was born. At the 2nd Guangdong International Printing Technology Exhibition, Zhengzhou Hongsheng Company perfectly demonstrated the application of JETALL water-based universal ink printing coated paper, and obtained many printing professional audiences. Praise.
Why is direct inkjet printing on coated paper so expecting and welcoming?
From the status quo of the printing industry
The vast majority of graphic companies, export companies, and printing houses print mainly on plain digital paper or imitation coated paper. Coated paper is one of the most widely used papers in the printing industry and has a large market demand. Because it was not possible to print directly on coated paper in the past, imitation coated paper appeared. The benefits of direct printing on coated paper are 3 points.
1. Save costs. At present, the coated paper for printing is calculated at 7,000 yuan/ton, converted into 200g/m2A4 format, and the cost of sheet paper is about 0.1 yuan/sheet. Commonly used 190g/m2A4 format digital proofing paper or imitation coated paper, the cost of sheetfed is more than 0.6 yuan / sheet.
2. Functionally, it can be directly printed on coated paper, which is easy to solve the problem of “following color” in digital proofing, because the proofing and printing paper are exactly the same.
3. Coated paper is widely used, and direct inkjet printing on coated paper solves the problem of printing media, and also brings a broader market for short printing.
From the application market of coated paper in the printing industry
Coated paper is often used to print prints, advertisements, landscape paintings, calendars, high-end books and other printed materials. It has great potential in application fields such as tenders, recipes, business cards, card certificates, product brochures, sample books, and short-run books. Coated paper has high smoothness and good gloss. It is widely used in short-run printing and digital proofing when it is used for color printing with clear image, bright color and high saturation. Short-run printing is widely used, and personalized printing has been realized, which is in line with the development trend of digitalization. Digital proofing shows that the equipment is low in cost, easy to operate, easy to "follow color", and has the advantage of large-format printing. It is gradually replacing traditional proofing and laser proofing, and the market prospect is huge. At present, coated paper is also increasingly used in the office field, greatly reducing the cost of paper for color printing.
From the development trend of the printing industry
Digital operation will become the mainstream trend. On the one hand, the intermediate links will be reduced, equipment investment and labor cost will be avoided, and work efficiency will be improved. On the other hand, the operation is simple and convenient, highlighting the personalized service, ready to print, with the change.
Since direct inkjet printing of coated paper is so popular, why is it waiting for the industry to wait for 10 years? What are the technical difficulties that need to be solved?
First, we analyze coated paper. The coating of most coated papers is not designed for inkjet inks. It has excellent affinity for printing inks, but has poor adsorption capacity for printing inks. It is the easiest solution to improve the inkjet printing of coated paper by changing the ink characteristics, but this solution is very difficult to implement and difficult to achieve under the previous technical conditions. Now, Hongsheng JETALL water-based universal ink has been completed, and on this basis, the paper proofing solution has been integrated.
Relying on the strong strength of ink research and development, Hongsheng launched JETALL water-based universal pigment ink, which retains the high quality, high stability, high color reproduction, waterproof and moisture-proof, non-fading, fast-drying quality of pigment ink, and with advanced constant temperature heating. The method allows the high-speed jetted ink droplets to solidify instantaneously on the uncoated coated paper, which makes the image set faster and the color is more vivid and vivid. The specific content of this program is "water-based universal pigment ink + modified heating device printer + ordinary coated paper", the core of which is water-based universal pigment ink. This product can print all the papers needed for printing, especially gold and silver cardboard, and can achieve low temperature printing at around 40 °C. Even thinner paper will not curl, and its "water-based" quality guarantees the operator. And the health of the surrounding people, the printer inkjet head also played a certain protective role, extending the life of the printer.
Coated paper printing scheme uses ink: water-based universal ink
Recommended equipment: EpsonStylusPro7908, 9908, 9880, 7880, 4880, etc.
It is necessary to modify the heating device of Epson equipment. The recommended heating temperature of the coated paper is less than 40 °C within 300g/m2, and the coated paper and gold and silver cardboard of 300g/m2 and above are recommended to be within 50 °C.
What are the advantages of coated paper printing solutions compared to traditional printing and other printing methods on the market?
First of all, the traditional printing method is difficult to achieve short-run printing of dozens of prints. Compared with digital proofing, traditional printing proofing equipment is costly, slow, and cumbersome. At the same time, it needs to be pre-made and then proofed.
Secondly, laser printing or electronic ink printing, the maximum printing format is limited to A3+, there is no way to print full-open, split paper, and it is difficult to "follow color", and the cost of equipment and consumables is high.
The use of weak solvent inkjet ink to print coated paper has occupied a certain market in the past. The advantages of water-based universal pigment ink compared to weak solvent ink printing are: (1) green environmental protection, protection of inkjet head; (2) no solvent component, non-toxic, harmless, non-irritating odor; (3) colorful , high saturation.
Through the early market understanding of some customers, the overall evaluation of the Hongsheng coated paper printing solution is: simple, practical, and high return on investment, which is very suitable for the traditional printing industry.
It is believed that the application of water-based universal pigments will greatly advance the green process of coated paper printing and inject new vitality into the traditional printing industry. Zhengzhou Hongsheng is willing to work with colleagues from all walks of life to make unremitting efforts for the prosperity of the inkjet industry.
