Existing Presses Upgraded
Akiyama International displayed a MEGA Jprint 40 series sheetfed press with in-line double coaters. The new version of the JP440 model is capable of speeds to 15,000 sph, while the JP540 achieves speeds to 14,000 sph. Improvements include more stable feeder and delivery mechanisms; a new sucker head for control of paper feeding; a swing gripper base made of a new material; a new mechanism to prevent sheet overruns; two additional transfer cylinders in the delivery section to suppress paper movement; and optional, fully automatic plate changers. Based on its 40? Bestech series, Akiyama also debuted a 16,500 sph SUPERTECH model incorporating several enhancements.
Sakurai exhibited three sheetfed offset presses. These included a five-color OL 596SDC with coater and IR drying system; a six-color OL 675SDWC, fitted with the wide option to handle 26x311/2? plates, and a coater and UV drying system; as well as five-color OL 566SD waterless press running technology supplied by Toray.
The centerpiece of the Goss International stand was demonstrations of its new M-600 Folia web press, which is designed as an alternative to sheetfed perfectors. Incorporating M-600 printing units, a custom sheeter developed in combination with VITS, the press prints up to 30,000 perfected sph on coated stock without a dryer and uses standard sheetfed inks.
Press options include Autoplate plate changing and DigiRail digital inking technologies, closed-loop controls, as well as the Goss Web center system for automated presetting, waste reduction and workflow management.
Magnum 4, Uniliner, FPS (Flexible Printing System) and Sunday 4000 press units with new capabilities and features were also on display, and Goss promoted the world's first 96-page Sunday 5000 press to be installed later this year by an Italian customer, who also ordered a second Sunday 5000 during the show.
Also on the web offset front, Muller Martini demonstrated variable-size web offset printing with flexo varnishing on OPP film on an Alprinta 52V; Drent Goebel showed a five-color, 33? wide VSOP with UV and EB curing; TKS touted its Color Top 3100CMUD single-width, shaftless newspaper and semi-commercial press; Tensor Group reported on current installations of its single-width models designed for the semi-commercial, insert and newspaper markets; and Web Press Corp. highlighted its Quad-Stack 4/4 color printing unit for adding color to existing single-width, one-around press lines or as components within complete press lines.
