Retaining Blacks

Tracy · August 10, 2011, 09:58:22 AM

Does anyone know how to retain the blacks while converting to profile?
I'm wondering if there is a way to make a pdf of a photoshop file
and converting in Acrobat and retaining blacks
so far nothing has worked.

You mean something that is C0 M0 Y0 K100 is converting to something else? In your PDF job options, I think if you set it like this it should stay 100% black.

what profile are you coming from and going to?
If it's doing it's job correctly, it will convert the black as well as the cmy. Why do you not want the black to change?

Sorry I wasn't clear
I have a flattened jpg with images and 100 black text
converting to profile for high ink density
converts the 100% black text into cmyk
I know this has always been a problem
just wondering if acrobat can convert it without affecting the black text
prolly not tho

from my dusty memory, a jpg is an image, and there can't be any "text".

I'm guessing she meant "words" in the image. :laugh:

I thought we weren't allowed to retain blacks after the emancipation proclamation.

Oh wait, this is something totally different.

I've been giggling in my head since I've seen this thread "is this a human resources thread"? :laugh:

if you do have a jpeg, is the text you want to keep as 100 k out in an open area where you can marquee select it and the give it a push curve to make it 100 black again, and then delete the cmy out of it?

I wouldn't go thru that much trouble :laugh:, seeing as part of the spread has 4 color black "text"
Just seeing if this is a solvable problem.

Joe where is that screen shot you posted?
in acro?

Taking this setting and idea one step further... you can change the CMYK setting to Custom in this dialog box, at which point it will open up another box where you can really screw things up. You can change Black Generation to Maximum, which will make that "text" 100% black with no under color. Unfortunately, it will do scary things to the colored parts too and don't forget to switch it back to Medium before you open another project.

Okay, Joe's screenshot wasn't from Photoshop, so my post is a little misleading. The way I got to my conversion was in Photoshop>Edit>Color Settings>Working Spaces>CMYK>Custom CMYK.
