Could You provide some arguments why PPA have chosen to use those
profile
settings.
Hi Marttila.
The settings chosen reflect the press spec preferred by the PPA
technical committee . As with all committee decisions it's a democratic
decision based on a number of factors including
quality/economy/speed/press stability/versatility etc.
There seems to be a lot conversation about high GCR vs. medium
GCR, but very little clear arguments why?
Our studio will use high GCR when separating 4 colour B/W and
neutral(ish) images in order to keep these images neutral on press. I
do of course hear some rumours regarding the use of high GCR purely to
save on expensive colour ink and the ability to run the press faster .
though I'm sure that must be untrue <BG>.
For more saturated images we will use much less black, and much more
colour(We use a family of profiles built for different image types).
TAC 310 is for sure much "safer"
even for quality glossy papers in heatset
exactly. As a committee , 'safe' must be the preferred route.
but I would say most of the
printers should be able to print also 350% without problems.
See current mail to Rolf, regarding personal approach to CMYK
separation.
My other question is about Profilemaker 5. You mentioned taht it gave
you
more freedom with TAC and black generation. I have myself used only PM
4 and
PrintOpen 5.1 but there seems to be quite a lot of options also in
PrintOpen. Is there some special options in PM 5?
From memory , PM 4 gives the same options regarding GCR ,TAC , black
generation. black start , black width etc.
