i`ve read your postershop profile problem at the list.
If you use default profile, PS uses the "default profile (cmyk/rgb)" stored
at postershop profiles. If you select no input profile, PS uses only
linearisation - no profiles for output. Try to use your agfa profile (RGB or
CMYK?) as input profile and the default printer profile as output. Before
that, you have to connect your output profile to your media/resolution/ink at
the postershop profiler. My experience is, that the measured paper whit has
mostly to be changend manually in print open. But that`s a trial and error
process and you have to decide visually, mostly i think it`s th "a" value
thats too low, so you get too much yellow in your greys.
I Think you should set your double stroke value at the same value than the
first stroke. Then you can decide the values for ink limitation. You should
select the values which give you a equal neutral grey without using any
profiles. Thats the base for printing your profile measuring chart.

Thanks for replying, I have a feeling your right but it wasn't the answer I
hoped for. Not your reply but what PS can do. I was hoping that with 'No
selected input profile' Postershop would look at the 4c file and convert
pixels to printer defualt pixels. My problem mostly is that almost all the 4c
(and spot color) files are not generated at work, but are supplied from
outside sources, and god knows what they use for seperations. I haven't tried
the Agfa 4c profile as input default yet.
I might be able to talk to some the regualr customers and get more info on
that.
As far as connecting my output profile to the media/lin/inklimit, that's not
a problem, I've done it for 3 machines and 4 materials.
Another question, when printing the Profiler target, I was selecting "No
input profile selected" and then process/print, is this correct?
How important is to have some ink double hitting, lookin at some of the
defaullt materials, the value changes. Is it a guessing game or are there some
density numbers to shoot for?
Thanks for your help, I'm sure I'll have more ? after more testing
tomorrow.
