Hi,
Conversion RGB to CMYK with ISOnewspaper26v4 gives the folowing results.
R: 0, G: 0, B: 0 conversion with relative or perceptual renderingintent,
with or without black point compensation.
ISOnewspaper26v4.icc (Coldset TIC240%)
TIC relative /without black point compensation: 229%
TIC relative / with black point compensation: 216%
TIC perceptual / without black point compensation: 240%
TIC perceptual / with black point compensation: 220%
The conversion to CMYK must be done perceptual and without black point
compensation.
Kind regards,

Hi ,
Running some tests on isonewspaper26v43 and am only achieving 213% tac
at L*0 on conversion. The spec says it should be 240%,
is there some
form of limit being applied to this profile?
Not much you can do about it. I had to recreate the profile out of the
embedded measurements with PrintOpen to finally attain the 240% limit.
