Convert RGB to CMYK, all colors to Black channel

[lnivin]

We need a CMYK (not grayscale) with all colors moved to the Black channel. Can PitStop do this?

So just to clarify, you want a Black and White job with everything on the K plate, and empty CMY?

 

[lnivin]

Exactly.

 

[abc]

yep, which version of PitStop do you have?

Perfect.

It's a two step process.

1. Do a convert to Grayscale.
There's a few ways to do it, Global change 'Convert to Colorspace' and configure it for Grayscale would be one.
2. Then once it's Grayscale and a single black plate, Use the Global Change 'Clean up black' and configure it to only have the option 'Convert Gray to CMYK Black' enabled.

That should do the trick

Thank you AGAIN!

You may need to ensure that elements that were solid black remain so and are not dark gray.

I suggest first turning off color management, then using the remap color global change and map all to Device Gray.
