Quality: Graphics print
DC-Grafiktest: dc_grafiktest.pdf.Quality of print: Fine lines
This test shows a printer´s capability to print fine converging lines.
HP´s color laser CP2025n is best here. The converging lines are distinctly visible right to the center. And moiré is light. Kyocera´s printer puts too much toner on the paper, lines become more and more indistinguishable the closer they come to the center.
Quality of print: Grey areas
Color lasers have two ways to generate gray: They print with black only. Black pixels and white gaps give the impression of grey. Usually the result is a visible raster. The second way is the use of all colors and black. Most of the time this results in a color cast, but the raster is finer.
The magnification shows, whether the printers use the first or the second method. Brother´s and Oki´s printers do it by mixing all colors and black, resulting in a heavy color cast.
Quality of print: Small characters
If you want to print wiring diagrams or blueprints your printer should be able to display very small characters.
The word "Druckerchannel" displayed below has a print size of 2 point, which is about 0.5 millimeters in height. It is five millimeters long and almost unreadable with the naked eye.
All printers in this test adequately perform this test.
Quality of print: Color channel registration
If you see white streaks between adjacent colors, the color channel registration is faulty. A channel registration is carried out automatically when switching on the printers.
All printers pass this test without fault.
