I'm on PC, and unlucky I found ACPU not so flexible,
for example I have found troubles printing on A3+ because it lacks the proper preset in the drop down menu
and I have noticed some strange behaviors regarding the margins settings (which now I leave set always to 0).
In the past there was a workaround called "double assign" to get the task done in PS, but it seems that in latest versions this trick is recognized by PS and is not more supported/recommended. It still probably will work, but I'm not sure because I have not tried it.
Maybe, for Epson users, there could be still the possibility to print out from PS with no CM:
in my humble understanding, by setting PS to "printer manages colors" and then setting "OFF (no color adjustments") in the mode menu of the driver panel settings,
it should do the trick, at least in theory.
I have tried to compare an Argyll target printed with ACPU and then printed in this way and found no difference,
but I'm not sure if this result was a lucky shot or not,
so I would like to have some other opinion regarding this workaround, in order to be sure I'm not missing something.
Thanks in advance for the attention.
Ciao.
