Resolution and PhotoART
600 dpi (High Quality) (also called 9600 x 600 dpi-class)
The magicolor 7450’s high-quality resolution generates photo-quality
output with great detail and character in fine lines and halftones by
printing 600 x 600 x 4 dpi resolution (600 x 600 dots per inch with 4 bits
per pixel). Also known as 9600 x 600 dpi-class PhotoART contone
quality, it provides 4 bits (16 levels) of gray or color per pixel rather than
only 1 bit (2 levels) per pixel which is traditionally found on many other
printers. A contone halftone consists of 4 bits per pixel, with 16 levels
per pixel. Combining all three printing colors, PhotoART screening
produces an incredible 4096 colors per dot. The result is the type of
high-quality output usually produced only by professional print shops.
Instead of producing only one size dot, the magicolor 7450 uses a
combination of dithering and dot size control to produce even fill
patterns, a wide variety of hues and shades, better detail, and more
accurate colors.
The magicolor 7450’s print quality is further enhanced by the printer’s
Simitri Polymerized Toner technology. See “Consumables,” later in this
guide, for more information.
