Hi Roger,
What time does it take from Monaco Profiler to measure an ECI2002
chart on
the Spectroscan? Or Fuji ColourKit?
We used a Spectroscan at my last position with Monaco. We were using
it on large format inkjet. I can’t remember the times but you would
have to consider the time to travel between the patches and a larger
target. The target that we were using was not an ECI2002 anyway. One
noticeable detriment to Monaco was is lack of ability to average more
then one reading. It would have to be done by reading the whole chart
multiple times. This would multiply the above point of travel time
between patches. Large format devices use an extremely course dot
pattern. I feel that averaging readings is an important point to
consider is this discussion.
I know that the Avantes Spectrocam uses an averaging routine and I’m
not clear if the eye-one is using a similar technique. Maybe someone
on the list can elaborate on the eye-one’s method of scanning.
Incidently, any opinion on the Barbieri 100xy? Reads in an ECI2002
target in
under an hour, uses a 5mm patch size as compared with 6.5mm for the
Spectroscan. Uses a D50-filtered tungsten light source as compared
with a
pure tungsten light source. Can be user-calibrated in the field with a
proper set of BCRA tile. But is it any good?
As for the Barieri 100xy, I was always at odds with the aperture size
issue and reading press control bars. The control bars are an
expensive proposition when considering the miles of expensive paper
being trimmed and tossed. Smaller is better for this reason. 5mm is a
good move in the right direction but would be a move in the wrong
direction without the ability to average readings. Calibration is
always a comfort issue with me. Anything that reads samples uses some
form of analog to digital conversion. I need to SEE that it’s
accurate before I’m completely comfortable. I would imagine that a
set of tiles, if they are ceramic, is a big factor in the cost of the
device. If the tiles are of another material, the accuracy becomes
another issue with the tiles and a replacement schedule of those
tiles. I am interested in how well is it supported in the area of
software as well.
