This is straight from the manual...
Standard: this setting generally produces satisfactory results if the
printing process on which the data is based is not known or no particular
specifications are made.
Offset print: typical default values for offset printing based on Euro
standard or SWOP for coated paper are used.
Newspaper: typical default values for news-paper printing with black
generated with UCR and the total dot area limited (for normal newspapers).
Color inkjet printer: typical default values for printing on ink jet
printers for offices on normal white paper or for higher resolutions on
coated paper.
Color laser printer: typical default values for printing on color laser
printers for offices on normal white laser printer/copier paper. These
printers frequently use their own procedure for the generation of black
(GCR) which is taken into consideration during the profile calculation.
Color copier: typical default values for color copiers (for example, Canon
CLC, etc.) which are controlled by a PC for printing and proofing on normal
laser printer/copier paper. Special settings for proofs are taken into
account during the profile calculation.
Proof (special paper): typical default values for proofing to high-quality
color ink jet printers (for example, Iris proofer) on glossy coated paper or
for proofing to thermo-sublimation printers. When the profile is calculated,
the proof table is optimized to include the largest color space possible.
Proof (normal paper): typical default values for proofing to color ink jet
printers (for example, Epson, HP, etc.) on normal or photographic paper. The
total dot area in the proof is limited for this type of paper (however, in
this case the maximum shadow that can be reproduced is not as high).
When you select your field of application, the parameters for the color
composition of the print and the proof table are automatically set with
default values which generally produce good results.
So... it is understood that there are certain differences in the algorithms
used for analysis and computation of the data based upon the source device,
it's typical paper stocks and it's colorants when preparing for the
generation of the profile. How spikes and other anomalies may be rectified,
how tertiary colors are evaluated, etc. More specific information is not
available as it is of a proprietary nature, and not for public disclosure.
As far as a specific setting for fine art reproduction, Standard would be a
good place to start. We've had excellent results with art repro going to a
variety of output stocks including canvas, arches, etc. And we never used
anything but the standard procedures.
