White threshold

Defining Trapping Rules and Exceptions
This parameter defines the maximum tonal value of Yellow which is still
regarded as white.
The default value (STANDARD profile) is 50.9%. The values for the Cyan,
Magenta and Black separation are calculated automatically from the respective
LUMINANCE value.
The WHITE THRESHOLD value specifies from which tonal value onward a
separation is dark enough so that the other separations need not be
trapped. A low value produces little trapping, a high value much trapping.
Black threshold
This parameter defines the minimum density of black which is still regarded
as black. The default value (STANDARD profile) is 98%.
Luminance
These values indicate the darkness of the process color separations relative
to each other. The darker the color, the higher this value should be.
The default values (STANDARD profile) are C=30, M=59, Y=11, K=100.
The value Y=11 means, for example, that Y100 appears as dark as K11.
Click on the list above to select the color separation whose LUMINANCE
you want to change.
Minimum tolerance
This parameter defines the degree by which two separation values may
differ without causing any trapping. Only those separations are trapped
which differ more than the percentage value specified here.
A low value produces much trapping, a high value little trapping. The default
values (STANDARD profile) are C=5.1, M=5.1, Y=9.8, K=5.1.

TOLERANCE you want to change.
Maximum tolerance

No trapping is made if all separations of the two color areas are dark
enough to exceed the WHITE THRESHOLD. However, if one or several separations
differ more than the tonal value specified here, they are trapped
regardless of this setting.
A low value produces much trapping, a high value little trapping. The default
(STANDARD profile) is C=80, M=69.8, Y=89.8, K=60.
