imagistics cm4530, cm3530 Color Manual

PREFACE

Thank you for purchasing the Multifunctional Digital Color Systems cm4530/cm3530.

This color guidebook explains simply the functions of the cm4530/cm3530 such as “copy

density adjustment”, “color adjustment”, and “image quality adjustment” in color.

To ensure effective use of the cm4530/cm3530, be sure to read the Operator’s Manual

[for Basic Function] as well.

Storage of Color Copies

- The copies should be kept in a place which is not exposed to light to prevent fading when they
are kept for a long time.

- If copies are kept with pressure applied between plastics made of chloroethylene for a long
time, the toner may melt and stick to the plastic. Keep them in polyethylene binders, etc.

- When a color copy is strongly folded, the toner at the fold can become separated.

- The toner on the copies may melt if it touches solvent or ink which is not dried completely.
Keep copies away from solvent.

- When copies are kept near an extremely high temperature source such as a heater, the toner
may melt. Keep them at room temperature without much variation.

The 3 primary colors of light represent red, green and blue light. The more the colors are
mixed, the brighter the resultant color becomes. Equal mixing of these three colors
produces a colorless and transparent light (white light). Mixing these colors to make
another color is called “additive color mixing”.

The colors of the cathode-ray tube of a TV and PC displays are produced by this method.

The 3 primary colors of color materials such as paints or color toners represent Yellow(Y),
Magenta(M) and Cyan(C). The more the colors are overlaid, the darker the tone becomes.
Mixing these three colors equally produces a black.
Mixing these colors to make another color is called “subtractive color mixing”.

The colors of printed matter such as posters and brochures are produced by
this subtractive color process.

Generally, printers use 4 colors of toner or ink, Yellow(Y), Magenta(M), Cyan(C) and
Black(K), which are mixed together to reproduce colors. (In theory, any color can be
made with the 3 primary colors, but black is difficult to reproduce since the 3 colors may
make it dark brownish.)
