Overprint and black overprint
Normally, when two colors overlap in Print output, the underlying color is not printed. It is
"knocked out", for two reasons: firstly, the underlying color may affect the top color, especially if
the top color is lighter than the underlying color. Secondly, not printing an underlying color,
which is not visible anyway, will save ink or toner.
However, there are cases when underlying colors should not be knocked out:
l
If the top color is a special ink or toner, such as varnish or UV, it should go over any
other colors, as it is meant to be transparent and go over other content. In Connect you
may enable overprint when you define a spot color; see "Defining colors, spot colors and
tints" on page283.
l
If small black text is printed over a colored area, mis-registration may cause white areas
to be visible around the text if the underlying color is knocked out.
The option to print small black text over other colors is referred to as black overprint. To
enable black overprint for text smaller than a given size:
1.
Right-click the Print context in the Resources pane and select Color Output.
2.
In the Text smaller than field, enter a text size (in points, for example: 3pt).
Note
Black overprint only works with CMYKblack.
Converting RGB black to CMYK black
In Print output, black is by default output as a CMYK color. RGB black is converted into CMYK
black.
If that is not desirable for any reason, it is possible to prevent it:
1.
Right-click the Print context in the Resources pane and select Color Output.
2.
Enable the Keep RGB black in output option.
In Connect versions prior to 2018.2, RGB black was not automatically converted to CMYK
black. Therefore, this option is by default enabled in templates made with an earlier version.
In new templates, this option is disabled by default.
