Resolution and PhotoART, Compatibility

Traditional Halftone Cell

1 bit/pixel

1 bit/pixel means the 600 dpi dot can be only one size and either “on” or “off” for 2 gray or color levels.

Contone Cell

4 bits/pixel

4 bits/pixel means a 600 dpi dot can be 1 of 15 different sizes or “off” for 16 gray or color levels.

PhotoART Screening

produces great color detail and

results in more gray or color levels.

PhotoART Screening

produces smooth gradients

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.
