I guess not , What your printer trying to do is making the Black as Rich Black because of which he is asking you to add C, M ,and Y in it.
100K black is a flat black with a dullness however because of these extra color a brillance get added to it.
the printer is not looking for a rich black. by spec'ing only 5% in the cmy channels, he is wanting for small text to blend into the other, surrounding color .
There must be some missing information here. If you have small thin text, you DO NOT want any other color mixed in with the black because those colors could peek out if there is any mis-registration on press. That would cause the text to look even furrier, not less. Also, at thin, small sizes the type will not easily show that black ink is not so black.
If there is color surrounding the text, the thing to do is simply overprint the black text onto the color, not mix tiny amounts of color into a custom black ink swatch.
How are you printing this? ie what kind of press?
To answer your question though, no, there is no reason to add any small percentages into your other colors. That will simply make them slightly less bright and clean.
Hope this helps,
Hi guys thanks for the help, I might have lead you down the wrong path here, when I look at this card again, its actually the text that is a "mid Grey color" that has turned furry. The black text is good and sharp, but I think I should be adding this extra 5% to the other channels on this Grey color to sharpen it up and get rid of the fuzz, I think that now makes sense.It's on a digital press.
Okay I'll remember no need for the other 5% on other channels.so how do you guys proof your CMYK work? I have a HP Laserjet 100 color MFP which I am printing to so I can get a look and feel for the print or if I need to show someone else, is this what you guys do too before going to full Press?
Ive read and some else suggested that printing to your own CMYK laserjet isnt going to be accurate as even though its CMYK desktop printer its going to expect RGB files (where as I set my artwork up in CMYK)???
I'm still not clear on why you need to add color to gray text. It too would look its best as a clean shade of black. I'd check your gray and see if it is already a colored gray.
A desktop printer is not color accurate for press work. Send your files to your press house and ask for a proof. They usually insist on one anyway, a contract proof that you sign off on before going to press.

I think he said his job is being printed on a digital press. Registration is not typically a problem, as opposed to offset. Still, requesting a proof is a good idea. Depending on the size of his gray text, adding small amounts of other colors can stabilize the edges of the type, depending on screen type (hopefully stochastic) but this would definitely not be recommended for an offset press.
If it was being printed offset, gray type should be an additional color.
