Wide-body inkjets
Article Abstract:
Wide-format inkjet printers are increasingly popular with graphic-arts studios that need to generate big, vivid images with today's high-quality inks and print media. Such printers typically use roll-based feed mechanisms that employ a continuous roll of paper or substrate and can also be sheet-fed. The maximum print area is usually slightly narrower than the media width. There are actually three different print methods used in wide-format inkjets: liquid thermal ink, piezoelectric and solid ink. Liquid ink is used in most desktop printers, requiring special top-coated media for best results. Piezoelectric printers use tiny electrical currents to force heat from the print nozzle and can use fast-drying oil-based inks. Solid-ink printers are less common and melt sticks of pigment into tiny and controlled droplets. New pigment-based inks are durable enough to use outdoors. Large-format printers typically have a maximum resolution of 360 dpi. Other issues include RAM, printer drivers and the host interface.

Aiming to please
Article Abstract:
Desktop color laser printers are an increasingly viable choice for graphics professionals as prices have dropped and color-matching capabilities have improved. Ink jet printers have made tremendous gains in image quality and dominate the desktop color printer market, but have serious disadvantages; they are very slow compared to laser printers, cannot serve as many simultaneous users on a network and cost more per page for color prints. Key specifications include maximum resolution, typically 600 dpi; color control and screening capabilities; and engine speed. The best printers offer variable dot size and apply 256 levels of CMYK toner for good continuous-tone prints. Engine speed is the maximum number of pages per minute the unit can print. All desktop color lasers have built-in RISC chips for page processing. Good printers have powerful raster image processors and large paper-input capacities. Buyers should also look for built-in network interfaces, remote management and wide network protocol support.

New views for PCs
Article Abstract:
When IBM introduced its 8514-A display adapter, it was the highest-resolution microcomputer graphics standard offered at that time. Now, PC display adapter manufacturers are retooling their clone boards to include 1,024-by-768-pixel features. Special software drivers for Ventura Publisher and Pagemaker now come with these adapters, so that desktop publishers can have high resolution. Of the boards tested, two have the quality and value recommended for PC desktop publishing. The best is Orchid Technologies's Pro Designer VGA Plus, available for $599. Second rated is Princeton Publishing Labs's Grafix Pro, costing $595. ATI Technologies's VGA Wonder displays Windows in black and white only, available for $699. The $1,099 Video Seven V-RAM VGA board did not have a 1,024-by-768 pixel resolution driver for Ventura Publisher 2.0, but it did have one for Windows-286.
