Paper used: multicolor prints with the thickness from 0.04-0.4 mm, especially suitable for short-length multicolor prints.
Main characteristics: The multi-color offset printing machine adopts instinctive functions for operation with plate cylinder cocking function and optional automatic plate mounting and demounting, automatic blanket cleaning system and ink key control system, delivering the fastest set-ups and changeovers, together with the fastest make-ready times in the industry (4-color changeovers are complete in just 3 minutes!).
1. This machine adopts V-shaped five-cylinder structure. Every two color stations share a double-diameter impression cylinder. Double color units are connected with two double-diameter cylinders and one tri-diameter paper transmission cylinder, which realizes four-color printing of each sheet with only seven transfers, seven transfers less compared with traditional cylinder structure, and is favorable for high-accuracy printing. Using double-diameter impression cylinder increases curvature radius of sheet during the printing process and reduces the bending of paper.
2. Double-roll and three-point eccentric shaft bearing of the rubber blanket cylinder realizes reliable clutching and stable pressure. Plate cylinder, impression cylinder and paper transmission cylinder all adopt the tapered roller bearing which completely eliminates the beating due to the gap between bearings.
3. High-strength base guarantees high-speed and efficient printing.
4. Conjugate cam driving and adjustable front guide and the swinging teeth fully guarantee continuous paper-feeding and accurate printing.
5. Specially designed delicate durable Feeder installation, continuous paper-feeding mode and side-wheel side guide ensure fast, accurate and stable transfer of papers.
6. Pneumatic braking makes ink-clutch fast and reliable. Horizontal and vertical adjustment without power off achieves quicker and more convenient registering.
7. Continuous alcohol-moistening mode with auxiliary roller ensures the prints bright and clear. Even if there is no alcohol employed, it can produce excellent prints.
8. The fountain roller is driven by an individual motor, and its speed can self-adjust to track the host speed, which would ensure that the water and ink still maintain a balance when the machine's speed changes.
9. Scientifically designed floating plate roller can effectively eliminate the ghost image.
10. Auto-cleaning device for rubber blanket would run just after clicking the button.
11. This machine is equipped with continuous water-feeding device and cooling water circulation device.
12. Dirty-resistant collection wheel guarantees clear print surface.
13. Optionally configured APC auto plate-mounting system greatly reduces the time for plate-changing and registering and improves work efficiency.
14. Optionally configured ink controlling system accurately controls ink amount and is more suitable for high-quality multicolor prints.
15. Optionally configured automatic plate cocking device shortens register time and improves work efficiency.
