color
The watermark color is available in Cyan, Magenta, and

Containing
characters
Characters embedded in a watermark, such as "COPY
INHIBITED," are called containing characters.
Kinds of
watermarks
There are two kinds: "Character appearing" and
"Background appearing."
When a watermark of "Character appearing" is copied, the
background disappears and the containing characters
appear.
When a watermark of "Background appearing" is copied,
the watermark of the character area disappears and the
containing characters become outline characters.
Principle of
watermarks
A watermark is composed of two dots: fine dots and rough
dots.
Since fine dots disappear when copied, they are called
disappearing patterns.
Since rough dots remain when copied, they are called
remaining patterns.
In a watermark of "Character appearing," the background is
a disappearing pattern and the containing characters are
remaining patterns.
In a watermark of "Background appearing," the background
is a remaining pattern and the containing characters are
disappearing patterns.
Note for
watermarks
Watermarks have the following characteristics:
• A watermark is presumed to be synthesized with text
documents. If it is used with photos or images, the
containing characters may be seen in the watermark
document (primary output) or the containing characters
may not appear properly in the watermark copy
(secondary output).
• When a watermark is synthesized with newspapers or
other dark-background documents, the containing
characters may not appear in the watermark copy
(secondary output).
• Containing characters may not appear in the watermark
copy (secondary output) depending on the kind of the
copier which makes the watermark copy (secondary
output) and the copy mode.
• Containing characters may not appear clearly in the
watermark copy (secondary output) depending on the
copy mode in which the watermark document (primary
output) is made.
• When the print engine status changes, the containing
characters may not be concealed properly in the
watermark document (primary output). In this case,
follow the procedures below to conceal the containing
characters.
* Use SIM46-24 to execute the color balance
adjustment.
* Use SIM46-54 to execute the color balance
adjustment for each dither.
* Adjust the watermark print contrast in the system
setting.
• Though the watermark of cyan or magenta is selected in
the black and white mode, the black watermark is
synthesized.
• For a document which is judged as monochrome with
ACS selected, though the watermark color is specified
as cyan or magenta, the black watermark is synthesized.
• The preview screen of the watermark only indicates the
setting of the watermark color, and does not indicate an
actual copy image.
• When the document control (printer mode) is used
together, it is advisable to use "Characters appearing"
setting. If "Background appearing" setting is used
together, the detection accuracy of document control
may be reduced.
• In the printer mode watermark, setting of 1200dpi and a
watermark cannot be used together.
