In Windows go to;
C:\ Program Files\ Monaco Systems\ MonacoPROFILER 4.6.1\ Preferences\ ScannerData.rtf
... and make a note of the NEUTRALRAMPBUMPS value.
Now modify the registry key in a terminal window by typing;
RUN REGEDIT
HKEY_CURRENT_USER/ Software/ Monacosys/ MonacoProfiler/ ScanLimits/
NEUTRALRAMPBUMPS
Adjust the value to be greater than the value found in ScannerData.rtf.
In Mac OS X go to;
Library\ Application Support\ Monaco\ MonacoPROFILER\ Input Statistics
... and note the "maximum initial
∆
E:" value.
Now go to;
Library\ Application Support\ Monaco\ MonacoPROFILER\ Input Limits
... and increase the " maximum initial
∆
E error maximum:" value to slightly greater than what was
reported in the statistics file.
If you still can't build a profile, contact Monaco Systems for help.
Gray patches not neutral
Q: Some of the patches in the gray scale seem to have color in them. Won't that upset the balance
of my profile?
A: No. So long as the reference file contains the actual CIELAB value of each patch, the software
should make a good profile. In the latest HCT design, some of the patches that were originally
'gray' have slight pastel-color variations to improve profile accuracy in near-neutrals.
Dark 35mm profiles
Q: Why do all my 35mm slides look too dark? I followed the instructions exactly.
A: Relax, this is quite normal and no, it is seldom a failure of the target or even the profiling
software. There are probably several factors at work.
First there is the problem of flare. If the darkest patch in the target produces lighter-than-normal
RGB values due to optical flare from adjacent patches (very common in 35mm scanners), the
resulting profile will add density to live images in which flare may be less active or nonexistent.
An 'extended range' profile may solve density problems caused by flare but see 'Scanner flare'
on the Instructions page for other suggestions.
Secondly, 35mm transparencies submitted for reproduction are usually selected under non-
standard viewing conditions that make them appear lighter than they really are. So a scanner
profile that works well for 4x5 or 8x10 inch transparencies will usually SEEM too dark when used
on 35mm transparencies. In this case the simple solution is to make a modified profile just for
35mm scans with a built-in lightening edit. See 'Lightening dark 35mm profiles' on the
Instructions page for more details.
