Second, the development of inkjet printing technology
1. The world's major manufacturers have accelerated the pace of entering the inkjet printing industry, and the frequency of new inkjet digital printing products has been significantly accelerated. Such as Kodak's Prosper series, Fuji Xerox's 2800 inkjet printers.
2, inkjet printing quality has been greatly improved, the resolution from 600dpi to 1200dpi transition, especially through the application of ink and coating technology, so that water-based ink can be printed on coated paper and offset paper jam, etc. The quality has been significantly improved, and the waterproof and offset performance has also been improved. Although there is still some distance from the offset printing, it can be expected that it will soon reach the level that the user can recognize.
3, the scope of inkjet applications is more clear and detailed, from the propaganda of major manufacturers can feel that their inkjet printers have a more clear and refined market positioning, such as: Fujifilm for short-run printing, screen for mixed printing, love Kefa is geared towards flexible packaging and flexo printing, while HP is facing books and newspapers. Kodak emphasizes direct mail and Domino for labels.
4, the supporting facilities are more perfect, the inkjet printing supporting post-press equipment is more perfect, more prominent overall solution, from front-end software to pre-processing, inkjet printing quality inspection and post-press processing, which is compatible with inkjet printing. Post-press quality inspection technology has become very important in the program. It can be seen that the relevant post-press supporting manufacturers in the traditional printing field are working hard with the inkjet printing manufacturers. In addition, paper suppliers such as UPM and Mitsubishi Paper have also introduced paper suitable for inkjet printing.
5, inkjet printing has challenged traditional printing, if drupa2008, inkjet printing is still positioned in a certain segment of the printing field, such as variable data printing, direct mail bill printing, etc., then at IPEX2010, Inkjet printing is undoubtedly the first publicly issued a more powerful challenge to mainstream commercial printing. Many inkjet printers have already claimed that inkjet printing with a print volume of 5,000 to 7,000 or less is already competitive. I believe that traditional printing machinery Manufacturers have been able to fully feel the pressure from inkjet printing equipment.
