A path to the default Gray ICC color profile.
The profile that will be used to convert any device Gray
specified in the PDF file to the device independent working color
space. This may be necessary when colors in different color spaces
need to be blended together.
This property can take a path to an icm file. However there are
also two special values you can use. If the property takes the
value "device" then the device color space will be used. If the
property takes the value "standard" then a built in default color
profile will be used.
If this property is set to "standard" or a path to a color
profile then IccRgb, IccCmyk, IccGray and
IccOutput should also be set to "standard" or paths to color
profiles. All color spaces are assumed to be device independent
If this property is set to "device" then IccRgb, IccCmyk,
IccGray and IccOutput should also be set to "device". All color
spaces are all assumed to be device color spaces.
If this property is set to a file name with no path information,
then the folder "<windows>\system32\spool\drivers\color" will
be searched to locate the file.
