Texture Print failures

Hi there, 

I am attempting to print a metal texture fill, when printed it changes colour. it is on cmyk settings, matching my printer settings. It seems to sporadically change between cmyk and rgb though, i am getting a pinkly purply hue over the top, I've tried changing the print settings and i am confident that it is not a problem with that process, however if anyone has had issues with that i would like to hear about it
