Photo help needed

Black & White photos printing with cyan

[Syzygy]

Printed off a nice b/w digital photo I took over the weekend on A4 archival matte. I converted the pic to CMYK through Photoshop and was perturbed to see the finished print come out blue & white. To be more precise it looks 100% K 100% cyan - what, I believe, is called a 'shiner'. Whatever, the print looks awful.

Why is this happening and how can I control it?

Thanks in advance.

Why would you convert a black & white photo to CMYK? However my first guess would be that one of the colors in your printer cartridge is empty.

Jecasc is absolutely right - there is no need to convert a b&w image to CMYK - try it in grascale... unless you wanted a little colour?

Greyscale - d'oh!

Thanks.

Additionally CMYK will only print correctly on a PostScript printer. For a sepia type tone here's a cool trick - convert to grayscale, then to duotone or monotone, pic your inks and tweak the curves, adjust, then convert to RGB. :-P
