HP Scitex FB7500, FB950, and TJ8550: The HP ( Scitex FB7500 is a UV flatbed inkjet capable of printing at speeds from 1500–5280 sq ft/hr, depending on the print mode. Designed for close-view, high-quality applications such as point-of-purchase and point-of-sale, the machine has 312 HP Scitex X2 piezo printheads (52 per color) with MEMS technology that support a maximum image resolution of 500 dpi.

The FB7500 prints on rigid and flexible media up to 65 x 126 in. and 1-in. thick and features HP Scitex FB220 low-VOC UV inks in six colors (CMYKcm) that are reported to provide two years outdoor durability. The machine also features a three-quarter automated loading system to increase productivity. Onyx I-RIP Plus software for HP Scitex drives the printer. The front-end software allows for loading new files during printing; queuing; step and repeat; and double-sided printing.

The HP Scitex FB950 is a 6-color (CMYKcm) flatbed industrial UV inkjet with optional roll-media printing capabilities. Four print modes are supported by the system to provide output speeds from 113–861 sq ft/hr. The FB950 can produce double-sided prints and full-bleed graphics at a maximum resolution of 1200 x 600 dpi. Media up to 98.4 x 80 in. and 2.5-in. thick can be printed on the machine. It comes with a media-loading system to minimize sheet-loading times and allows simultaneous printing on up to six sheets of rigid media.

Inks are in three-liter containers; interactive technology tracks and displays the amount of ink remaining for each color, allowing the operator to monitor the ink and plan ahead prior to long print runs. Other FB950 features include an onboard camera-based printhead alignment system, automatic printhead maintenance, and a touch-screen user interface. Roll-feed and take-up system is optional, as is a second set of roller tables.

The HP Scitex TJ8550 printer is a 6-color UV inkjet designed for high-speed printing of flexible media. Built on the company’s TJ8500, the roll-fed device offers a higher print speed and better ink coverage than its predecessor, HP reports, and also has a new dedicated inkset.
