Digital BW, The Print

Carl

As part of my continuing poking under the hood of QTR I printed the 21 step
wedge file 21step.psd using firstly your 100% EEM cool then 100% warm (and
then also a curve using just the 27/27/56 LC/LM/LK mix you used to produce a
cool LK in order to see clearly the hue of the cooled LK).  In each printout
there is on the top 1/3 part of the strip which has the smoothed transition
a dark patch from 100 to say 97, ie at smooth transition abruptly stops
around 97 and 97-100 is the same shade of grey.  I suspect that this should
not be the case ­ it is not that way on the screen.  What¹s causing this?
Is it simply that the two ends of this image are not part of the scale? ­ I
note that when looking at the stepped (bottom) part of each image the 100
and 0 blocks are wider than the rest and the dark patch I see kicks in
exactly 1cm to the left of the right side 100% marker (each 5% block being
1cm).  If this is the case I am surprised that the extra bit on the left is
abruptly darker than where the 100% mark would be.

Can you also explain to me the second scale on this file ie 0-160.

Cheers

Steve
