Light optimization
In order to obtain a scan of the highest quality, the
lamps must have a constant light stability
throughout the entire scanning process. If there is
not a constant light stability before a scan, the
following message appears:
Light optimization running
(in the case of
Linocolor with the addition: – Skip with ”Cancel”).
If you cancel this message, there could be a
minimal loss in quality in the case of critical
originals containing, for example, large color
areas of the same density or shading. A loss in
quality was not discerned when using normal
originals.
Tips to avoid the message:
1. The message also appears when switching
between transparency and reflection illumination.
Unnecessary switching over of the illumination
modes should therefore be avoided. Process all
transparency scans first and then the reflection
scans or vice versa.
2. As reflection lamps switch off quicker than
transparency lamps, the reflection scans should
be processed swiftly. This avoids forced switching
off of the reflection lights (thus no new message on
switching on the lamps).
3. On selecting the scanning quality
Very good,
Excellent
and
4x Excellent
(only for Linocolor), the
light optimization function is activated. The
scanning quality
Good
is therefore recommended
for non-critical originals as the message does not
appear in this case. This also applies to the course
scan (prescan).
