Wide-format printing gains accuracy from Edgeline technology

HP's Edgeline technology is proving very versatile. First used last year in a photo printer aimed at kiosk applications, its use in the CM8050 and CM8060 departmental MFPs has gained plenty of attention. But the company has also applied it to wide-format printing for technical users.

The DesignJet T1100 is aimed at three main subgroups: architecture, engineering and construction (who primarily need line drawings), mechanical engineering (eg for 3D renderings), and geographical information systems (GIS) where information from databases must be overlaid on maps or satellite/aerial photography.

The T1100 uses the same Edgeline printhead as the CM8060, but prints a 1in (2.5cm) wide band across the 24 or 44in page rather than having multiple printheads to cover the entire width without moving as in the CM8050/8060. This printhead allows a minimum line width of 0.04mm with an accuracy of +/- 0.1 percent (compared with an industry average of +/- 0.2 percent).

The cyan, magenta, yellow and black dye inks are augmented with a matte black (which gives a better match with the coloured inks than the normal black) and a grey for smoother transitions.

Print speed varies according to quality and the type of paper. Draft mode produces an A1 page in 35 seconds, while best mode on glossy paper on the 44in model is rated at 2.8 square metres (30 square feet) per hour. Roll and sheet feed is accommodated.

Files are processed in the printer, not by the host computer. This frees up the PC more quickly after the print command is given, and the controller's hardware is fast enough to begin processing the another job while the current one is still printing. It also means that files can be printed from a PC that does not have the appropriate application (eg AutoCAD) installed, explained Martin Carballo of HP's large format printing business in Asia Pacific and Japan.

The T1100's colour management software includes the ability to match the colours used by older printers. Even though the result is less accurate colour, it does maintain consistency where that is important to the user.

Prices range from $US4500 for the 24in model to $US7000 for the 44in model with PostScript.

While the T1100 is designed for workgroup use, a similar printer for individual use will ship in July. The T610 has less memory, no hard drive, lacks the T1100's networking ability and does not have the option of PostScript.
