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.
