We’ve assembled a sampling of the high-speed on-demand presses currently on the market, and present them here. Each offers at least 4-color output, can handle complex variable-data printing, and is no smaller than 12-in. wide.

Agfa offers two variations on its Dotrix printer: the Transcolor and the Modular.
The Dotrix Transcolor is specifically designed for complex variable-data printing, and features CMYK x2 UV-curable Agorix Nova inkjet inks and resolutions that reach 300-dpi grayscale (900-dpi apparent). The rollfed Transcolor offers a maximum print width of 24.8-in.; compatible substrates vary from 48 to 380 gsm for paper, and plastic thicknesses range from 50 to 400 microns.

Like the original Dotrix unit (see below), the Transcolor features the single-pass color engine (SPICE). The machine’s printheads span the printing width, and the substrate passes underneath, allowing for printing on both sides (duplex) in a single pass. Its intelligent printer data stream (IPDS) controller processes variable-data pages in real time for speeds up to 24 mpm or 484 ppm or 29,000 pph.

Transcolor’s standard configuration is roll-to-roll with a jumbo reel unwinder and rewinder. Options include an in-line slitter bar and an inspection table; other compatible in-line and off-line finishing equipment is also available.

Agfa also offers its original Dotrix Modular unit. Like the Transcolor, it offers 300-dpi resolution, grayscale printing with Agorix UV-curable inks (CMYK), 24.8-in. print width, and is armed with the 24 mpm SPICE engine. The Dotrix prints single-sided and accommodates substrates from 25 to 600 microns thick. It comes standard with a jumbo unwinder/rewinder, and offers flexographic printing stations, slitting, and die-cutting converting options

Canon’s imagePress C7000VP images at 70 ppm for color printing on letter-sized paper with resolutions up to 1200 x 1200 dpi. Armed with its automatic duplex capabilities, it handles 64 to 300 gsm paper up to 13 x 19 in. and offers a 10,000-sheet maximum sheet capacity. It also features Canon’s oil-free V toner with 5.5-micron toner particles for sharp details; in addition, its new Gloss Optimization toner technology gives the look and feel of offset printing, Canon reports. Paired with the imagePress Workflow Solutions, a suite of hardware and software, the press allows for variable-data printing. Optional finishing accessories include a stacker, saddle stitcher, booklet trimmer, puncher, and more.
