I am wondering what the real skinny is on Light Generation.
My printer at a bucket shop/Web press wants me to use Light Generation
which helps them adjust on the press on my next CMYK delivery.
I have been reading here that the Medium or Heavy will keep the image
more pure. US Web Coated SWOP v2 is Medium as a default already right?
So I am at the proverbial crossroads once again. We are essentially
printing a bunch of neutral grey and black metal product images in this
application at this printer.
If I understand correctly, And in keeping with this, I have also been
told that if you invoke Custom CMYK dialog box found in Photoshop>Color
Settings to alter things such as TAC, or select Light Generation, it is
a low grade solution as it builds a profile that is comprised of very
few points, is small, and not very accurate. Yes? No? This would
include adjustments to the UCA 5%. Is this a generally accepted fact?
I still see this touted in todays digital magazines as a proper method
of tailoring CMYK output. Just got one in the past couple months.
Are they disseminating old marginal information?
Wouldn't one be best served by simply doing a better job of adjusting
or preparing an image in RGB, with Soft Proof side by side with regards
to forcing the proper end points and pulling off some heaviness via
curve adjustments so that the numbers needed for TAC, etc.. are in
place before AND THEN CONVERT to the destined US Web SWOP Coated v2
profile.
I am nervous about mucking with the old Legacy PS4 CMYK SWOP Engine
just to force a Light Generation.
Is the Chromix's Light Generation 280 profile I keep hearing everyone
talk about simply a US Web SWOP Coated v2 profile with a Light
Generation and 280TAC as opposed to standard Medium and 300?
If so, it would seem then that a solution like that would be much safer
than invoking the ol Legacy PS4 engine.
Thoughts?
Thanks in advance,
