Title: Preflight for black text
Post by: elko on October 12, 2018, 12:30:25 AM
Hi

is there posssibility to check rich black text/obejcts in preflight? I can use an action or global change to fix it, but it would be better to check it in PS server and fix it from preflight report.

I'm not sure about previous versions of Pitstop, but in Pitstop 2018 under color in standard actions is a Check for Rich Black.

Using remap color is better because you can add additional RGB black, or even cmyk builds of black and map them to device black, separation black, device, etc. It makes the action more flexible/intelligent.

I'm not 100 sure how Pitstop handles it exactly but the mouse over description shows this. I think there might be range of how close the individual channels of RGB/CMYK are to each other. If they are too far apart nothing happens but if they are within whatever that range is it will change them to black/gray.

Hopefully ABC will drop by and maybe give a better explanation than that.

Not sure if it is the way you want to go but you can put an action into a preflight.

why isnt it implemented into preflight and one have to get action into preflight??.... that is preflight issue
.....the preflight check for impure CMYK doesnt work for any CMYK values without 100% black....  when the check finds impure CMYK and I want to fix it, the navigator offers me remap color menu and I have to add collor rule to replace the objects to real black. It seems to me very unconfortable. Yes, I can set to replace automatically, but I like overview and fix it by myself...

there is test file and test preflight.... I run the preflight and the added action finds only one objects and doesnt offer me a fix...  possible way but not good

Just for giggles I tried the almost black to real black action and it changed your test pdf to 100K
This can be added to your preflight, but the thing that got me looking at this action is
you can put in a range of your colors, I remember from the Pitstop Webinars but I have never
needed to use this action.
just fyi you will have to duplicate-rename the action to edit I'm pretty

The flexibility of the preflight action is limited. By using the remap color action and putting it into the preflight profile you make a more intelligent and flexible preflight profile. Down the road this is a smarter way of working.

matt: I dissagree. Iit is not smarter for me. There could be same setting for CMYK values and so on as it is in the action in the preflight settings. There could be a button "make it real black" in the navigator (with the preflight results) that should change the collor as the action and the automatical fix do and one doesnt need any collor menu to fix it. The issue is impure black so your aim is the real black one doesnt need more. For the case I shall need more, there could be the smarter and intelligent way of added action.

Bizarre, but if it doesn't work for you then that's fine. Remap color provides a huge amount of flexibility that the built in logic doesn't have. Too many combinations to account for. Even callas and its logic has limitations where using color mapping is more flexible.  You essentially set a range of CMYK colors and have them mapped to separation black, k of cmyk, device gray, etc. And it does it without havin to step through the preflight results; it's just "done'. Much more simplistic and powerful. Your mileage varies.
