My workaround for the PS6 -> PS7 posterization problem...

2002-07-12 by Ricardo Lagos

I finally decided to stop trying to fix PS7 posterization -- the problem is when converting to RGB from greyscale -- and i have no idea on how to fix that (a transfer curve to make up the difference?)

.. my current workflow is to use PS7 for all manipulations in greyscale -- (and test printing using paul's GS curve) -- this works just fine in PS7 

(BTW i want to use PS7 because i'm now running OS X) ..

.. when i'm ready for some final prints -- i load up PS6 - convert to RGB -- apply curve -- then save to another filename)

..then reload on PS7 and print .. 

i'm guessing that i could also do the curve applicaiton in PS7 -- since the problem is when you do the greyscale to RGB conversion..

.. btw i tested this yesterday and got great prints
