color issues

[Hog Wild graphics]

I'm having trouble with black. If I print 0,0,0,100 its ok but if I print rgb or any form of rich black it prints navy. The problem is I trying to print a supplied jpeg and the black is navy.

Anyone have similar problem?

assuming your heads are all firing ok, this will be a profile issue. are you sure you are using the right profile for your ink/media?

All profiling, probably. Failing the creation of a new profile, did you try to just manually dial back the Cyan in your RIP for this one job?

I am assuming you are using versa works? What color management profile are you using? Have you sampled the color in photoshop to see what the RGB values are for the black?

I found a few webinars and a document that discuss grey scale color control. There is usually some discussion on hitting blacks as well. Based upon the feedback, it's clear that we should add a webinar on this topic. Please keep an eye on our schedule (http://www.rolanddga.com/training/workshops ) for a webinar down the road. Here are a few links to the topic:
