Appendix

In the case of a printer, it is not possible to change the intensity of toner colors.
Because of this, a much larger number of dots are used compared to a computer
display, and various colors are reproduced by adding K (black) to the C (cyan), M
(magenta) and Y (yellow). This means that higher resolution color prints are
possible the smaller these dots are.
About Color Printing
In color printing, the shape and color of images are expressed in groups of minute
cyan, magenta, yellow, and black dots.
Therefore, image data input to the printer is divided into cyan, magenta, yellow, and
black.
The data is reproduced separately on the light sensitive drum for each toner color,
and the toner is transferred onto an intermediate transfer medium.
