DI printing machine

The Direct Imaging (DI) press made its debut in September 1991. Today's DI presses are available in double, quad, and eight-panel formats. Half-format mid-size presses include: • Adast's 26-inch DI series presses, four- or five-color printing, and computer CTP direct platemaking (optional), and With high-speed output and double-sided printing, printing speeds up to 10,000 iph. • The Heidelberg Speedmaster 74 DI 28-inch press, which can use traditional or digital plates, uses CreoScitex's SquareSpot thermal imaging technology, and produces 2400 dpi plates in six groups of printing units. Touch screen control for direct imaging. The maximum speed is 15,000 sph. Thermal imaging plates can be made using Saphira (co-developed with Agfa) thermal printing plate or Presstek's Pearl Gold printing plate. The Kodak Navajo Edition is part of the product being tested. · Karat Digital Press There are three different types of customers: they are prepress providers, commercial printers and special printers (for internal or greeting card printing). Its Karat 74 printing machine is specifically designed for the medium and short-run printing market with up to 20,000 sheets. The product adopts Gravuflow ink-free self-adjusting ink system, four-color waterless printing, ready time is only 20 minutes. It also automates plate change, imaging and cleaning through new job parameter settings, reducing machine idle time. Printing plates can be automatically imaged, loaded, and unloaded, and most printing jobs can be completed through the console. At 10,000 sph, · Sakurai's 74 EPII DI has a 29-inch double-sided printing function as a Q2 series press. The machine uses Presstek's ProFile imaging technology, either direct DI imaging or conventional methods. Automatic programs include: plate change, ink density adjustment, paper settings, and more. The maximum printing speed is 13,000 iph. • Screen's TruePress 744 is a four-color single-sided or double-overlay printer with a print size of 29x21 inches, similar to its double-deck DI TruePress 544 press. 8000 print speed, can complete 3000 full format products printing in half an hour. Automation programs include: plate unloading, imaging, rinsing, fixing, printing and blanket cleaning. Other two-color or six-color printing specifications are also available. Development Trends The single-stream inks that emerged at the Drupa 2000 show were also a blessing to Presstek's ProFire and CreoScitex's SquareSpot because it dispensed with the dampening system and used DI imaging heads directly. In addition, at Graph Expo, CreoScitex also demonstrated their SP unprinted digital offset system installed on the Shinohara 66 IIP press. Clint Bolte, an advisor to Clint Bolte & Assocites, commented in the GATF World: "Since this kind of laser-imprinted polymer material was applied directly to the plate sleeve, it was possible 10 years ago. On the machine, then why can't this coating method be used on all printing machines? It (direct laser imaging) is an excellent complement to CTP technology.” But don’t think that this kind of printing technology will soon be It will come at least two years from now. But anyway, keeping an eye on its development should be the right choice.
