Roger,
Agree with you on that, although the instruction from IFRA did stress
the Perceptual / BPC off combination in order to achieve the 240% TAC
target.
I had assumed it was ReCol BPC on, but that gives this low 215% TAC
value, although I actually prefer the look of the conversion. Truth is
with this target condition the amount of degrading that has to come
from the substrate used means you have to be pretty brutal, there's
not really the opportunity to be subtle!

Eric,
Sorry this didn't strike me before but, just an observation about
using the
Perceptual rendering intent in Photoshop.
You know that whether BPC is checked or not has strictly no effect
whatsoever on the outcome of the conversion. BPC only comes into
play when
the RelCol RI is selected in the RI drop down listbox. That's
confusing, I
agree.
I wish, by now, Adobe would have implemented graying the BPC
checkbox when
the user selects the Perceptual RI, in the ConvertToProfile dialog,
as that
would kill this confusing state of affairs once and for all. But, as
usual,
the Photoshop engineering team has lots of other priorities on their
hands...
Putting a simple Lch readout in the Info palette does not seems like
one of
these
:(
Guys, have a heart!
Roger
Just to repeat a post I made to the list last year with regards to
ISO
Newpaper 26V4, in order to achieve the target TAC value of 240% when
converting in P'shop, the intent must be set to Perceptual with BPC
turned OFF, otherwise the TAC stays down around 215%. There is a
version of this profile from BasicColor which I prefer as it is a bit
more colourful and every little helps in Newsprint. And finally there
is also a recently released PSO SNP profile, for Standard Newsprint
Paper for heatset printing.
cheers
Eric Nunn
