I'm currently dealing with a printer, who I've been working with for a year or two. We've sent off to had one of our brochures reprinted - the same files as last time, except now they're having some problems with the files. The exact wording in their email was:
We have a bit of an issue with your files, the black text has been set up so as it prints as a composite of 4 colours, rather than just black. This will cause a printing problem as the slightest movement will make the text look fuzzy. We can often correct this using the software tools we have but this has not been successful on this occasion. Are you able to re-supply the files with the text as black only?
I looked at the files and I appear to have been supplying them in RGB rather than CMYK, so I thought that might be the solution, however, the problem persists.
How would I have configured black in my files to print as four colours rather than black and how do I go about fixing it? Sounds a little strange to me, as it sounds more like a printer problem - but I'm not printing expert/professional.
