A post in the Alt.scanner ng dated 8/12/98 says a US Airforce employee ( author
) did a survey that calls scanner makers claims about scanner resolution and
color density lies. The scanners used were drum ( they performed as claimed )
to CCD. The poster was Phil Lippincott. This post also asserts that Binuscan
only helped color response slightly and did nothing for dynamic density. My
two scanners , a HP 6100c amd A Umax Mirage 2 claim 3.4 and 3.6 respectfully
they also claim 600 DPI for the HP and 1400x700 for the Umax and in high
resolution mode 2800x1400 ( with the double lens on a reduced area ). The
survey says that NO CCD scanner can get higher than 2.7 color density.
Resolution was also challenged by CCD scanners as exaggerated claims by the
scanner makers. Mr Lippincott used a KODAK standard color density step chart (
poesative transparency T-126 ) to test color and a 1954 optical quality chart
which is nimbered with lines dowm to 1 part per millimeter to test optical
resolution. I plan to use these to test my scanners. What is most sugnificant
is that the Binuscan software does very little improving. HMMMMMM.
