Convert bunch of RGB images in PDF into specific ICC CMYK

Post by RedstoneRepeater »

Hello, forum.

Let's say there's a production environment with 2 roto and 1 flexo machine. Most relevant combinations of LPI's, substrates, ink systems, foam softness, gravure angles etc, are properly caputered by ICC profiles. So we have 11 main ICC's.

Now, there are a lot of RGB images in input PDF from customer.
How can I quickly tell PitStop:
"Reseparate all RGB images and all RGB lineart colors in this PDF into specific profile, e.g. "Flexo_OPP_175_2" ICC profile? "

Re-separation into generic DeviceCMYK is not good enough.
The Color tools > "Convert Color" panel doesn't seems to be able to process the whole document.

Thanks for suggestions.

What you want is an Action List. There are many ways to approach this, but the easiest is probably this:

Override colour management settings with as CMYK output profile the one you need.
Select all
Convert to CMYK
Tag with ICC profile, again the one you need.

You might want to exclude specific objects such as text to prevent them from becoming 4 colour, but that will depend on your specific workflow.

I suppose it's not achievable with action command...?
So each time, I need to go to go into PitStop Preferences and manually set one of my 11 ICC CMYK profiles?

Well...
Thanks anyway :)

It is. In the Action List editor look for "override color management settings".

Yes, that's a good hint.

For anyone looking, I finally used the factory-made action "Standard > Color > Convert all RGB to CMYK", but with slightly modified ending:

Code: Select all

… 
…
Override color management settings > 
    > Enable Color Menagement: YES
    > ….
    > …
    > CMYK: np. Fogra 39
    > …
Convert Color to CMYK
Tag with ICC Profile Fogra 39
Thank You, Your knlowledge is appreciated.
