PS6 vs PS7 VM saga (Martin)

PS6 vs PS7 VM saga (Martin)

2002-07-18 by jimhayes361

Martin,

First, I as well would like to thank you for an excellent review of 
the Piezotones. As you continue to use them, can you and others report 
further experiences, esp. wrt longevity, ink consistancy/performance 
over time, etc....as I would like to keep as close an eye on these 
products as I can with the possibility of switching from MIS VM.

Speaking in the present for me however, you had asked me a week ago to 
convert stepwedges from gamma 2.2 to both sRGB and Adobe98 in both PS6 
and PS7, to see if sRGB was indeed not mapping in the darker areas.

Well, everything matches. I even used Paul's stepwedge with gradations 
in 1%k increments after 95%k and both PS6 and PS7 with either color 
space give me the correct %k after conversion. Of course this does not 
include the addition of of a correction curve layer-  to convert it to 
a false color image.

Yet that dark test print still printed differently depending on color 
space and PS version.

.........

Anyway, wanted to get back to you (and others, if anyone still 
following) on that. I may not be going on vacation as I planned, as it 
seems every day we get a new fire in Colorado, some of the latest 
ones, still small, very close to us. Yesterday one started only 20 
miles away and is still going strong. So  I might be hanging around to 
evacuate stuff if needed. This has really been a bad weather year.
