Servo-driven hybrid unit adjusts register during speed changes

Available in 10-, 13- and a new 16-in. web width, the Aquaflex ELS servo flexographic press has a two-roller inking system, which co. says allows print speeds up to 750 fpm with no ink disturbance. The servo-driven electronic line-shaft press prints on papers, foils and films, and its trademarked Intuitive Register Control is engineered to adjust registration automatically during speed changes to produce saleable product throughout the full range of speed changes. The press line has been updated with a high-capacity dryer package for non-absorbent material, and a UV-drying option also is available.

Digital printer replicates most spot colors

The EFI Jetrion 4000 UV prints on webs up to 6 in. wide at speeds up to 100 fpm. Co. says the printer’s four- and six-color UV ink sets allow operators to replicate most spot colors used in narrow-web applications. Substrate range includes supported and unsupported films, foils and papers. Among a broad range of finishing options are semi-rotary, full-rotary and laser diecutting capabilities.

Inkjet array prints 900-dpi quality

The :Dotrix Modular uses a stationary array of inkjet heads to print up to 9,700 ft/hr. The piezo drop-on-demand inkjet heads produce different tints by varying the drop volume, achieving image quality comparable to 900-dpi full-color printing, says co. The roll-to-roll servo-driven press has a jumbo unwinder and rewinder, a maximum web width of 25.6 in. and a maximum print width of 24.8 in. Web speeds range from 16 to 78 fpm. Foils and plastics from 25 to 600 microns thick can be printed. Substrate pretreatment options include corona, web cleaning and anti-static. Traditional flexographic printing stations can be integrated inline for difficult substrates, laying down flexo white or spot colors, or finishing products with lacquer. Slitting and diecutting options also can be teamed with the press.

“Six-print-process” combo system runs at 525 fpm

The Gallus RCS 33 supports six printing processes: UV-offset, UV-gravure, UV-flexographic and rotary-screen printing, and hot-foil and cold-foil embossing—either individually or in combination. The press operates at speeds up to 525 fpm, with a maximum web width of 13.1875 in. and a maximum printing and process area of 13 in. Flexographic, screen and UV-gravure printing, and hot-foil embossing have a minimum repeat length of 1 ft., a maximum repeat length of 2 ft., and standard repeat length increments of 0.125 in. Substrates range includes monofoil, label PET, PVC and OPP. The RCS 33 press also can be custom configured to work with paperboard.

Multi-process press changes over “on-the-fly”

The Comco C2 has intelligent multi-process print decks that are easily configured for additional imaging processes, including flexographic, UV-flexographic, screen, gravure and cold-foil. The C2’s trademark I-Drive (Intelligent Drive System) integration combines servo technology and advanced controls, which co. says greatly enhance productivity, print quality and flexibility. The I-Drive consists of fully servo-motion functionality that is shaftless and gearless; exclusive, specialized programming; closed-loop control of print pressure; servo-driven mandrel/sleeve print units; anilox and plate-roll sleeves that change out in a single motion; “on the fly” changeover capability; and the ability to instantly engage and disengage flexo mandrels without stopping the press. For additional flexibility, the C2 also can be outfitted with a variable-data inkjet printing system.

Mid-web system unites gearless- offset with UV/EB curing

Co. will debut a 6-color, 33-in. VSOP (variable sleeve offset printing) with UV/EB (ultraviolet /electron beam) curing at next month’s drupa. The press will be shown printing on film that will be converted to wraparound labels, shrink-sleeves and flexible packaging. Ac-cording to co., the new UV/EB capability is the result of a collaborative effort between Drent Goebel and Energy Sciences (ESI), IST METZ UV and Air Liquide. ESI developed an EZCure EB unit especially for the VSOP press line; IST Metz installed its new BLK-5 lamp with an inert-gas system on the press; and Air Liquide integrated its nitrogen-delivery system. The press’s sleeve technology enables flexo printing results from an offset press, and the line’s modular nature allows further configurations with screen, gravure and digital printing capabilities. Finishing options include hot-foil stamping, laminating and diecutting.
