: How to change blacks to 100% black in Illustrator? I've been stuck with this problem for a few days and I just can't seem to figure it out, hopefully someone can help! I did a job where
I've been stuck with this problem for a few days and I just can't seem to figure it out, hopefully someone can help!
I did a job where I edited a brochure, the original design files were destroyed and all that was left were the final PDFS. I made the edits on PSD, I deleted the old text and placed a new text layer on top. I changed some of the text but most of it stayed as it was before. I saved the files as PDFS and sent them to the printer.
The printer asked me to change all back to 100% black (C=0 M=0 Y=0 K=100), I changed the color on all the edits I made to 100% black but the old text is at C=75 M=68 Y=67 K=90.
I tried opening it on Illustrator and changed the appearance of black but nothing happened. I figured maybe the changes would be seen when I exported the files, but that was not the case. I exported the file and checked the black again, nothing happened.
I'm I missing a step here? I have been reading online but none of the forums help. I don't want to change to grayscale because the document also has colors in it. I attempted to change on Acrobat but that was a big fail as well.
is there any way I can change the black to 100%!? I really don't want to re-do the whole brochure, I am sure there is a way around this I just can't seem to figure it out.
here is one of the pages if you want to take a stab at it: www.dropbox.com/s/a4ary3bldm3vtio/4_33.pdf?dl=0

Make sure that wherever you are working on this file you are working in the correct color space. Photoshop and Illustrator can both be finicky when it comes to converting colors when you aren't in the appropriate color space. On the tab with the file name you can find which color space you are working on it'll say something like "File.pdf @ 100% (RGB/GPU Preview)." If your file says RGB then your problem comes from illustrator taking that 100% black and changing it to RGB black. In Illustrator go to File > Document Mode > CMYK Color and in Photoshop go to Image > Mode > CMYK Color. Then change the color to 100% Black and export the PDF again.
Alright, well I would retype it cause you'll get much better results but if you really need to do it, here's what I came up with for you.
Go into your channels. Select any areas of composite black
and with CMYK channel (the top composite channel) checked, do Copy. Then go to the Black channel and do Paste.
Now reselect and go into the Cyan and fill with white, the Magenta and fill with white, and the Yellow and fill with White. Congrats, you're done.
