Minolta c6501 - Black text prints as CMYK, any solution?

**bgardner** · 05-19-2011, 11:59 AM

Since Minolta can't figure this out I would like to see if anyone else here has. I thought I saw a post like this before but I can't seem to find it.

Lets say you have text typed out in an InDesign Document. The fill color is applied as the default Black swatch thats always in InDesign. You convert this file to a PDF, with no compression, no downsampling, and more importantly no Color conversion destinations.

When you import that PDF into the fiery, it prints all the black elements as CMYK builds, such as the text, and it looks real choppy. It also does it with grayscaled images (grayscale from PS) and it gives them a color cast to it.

Sometimes I find you can convert the text and images in Pitstop to gray, which usually fixes the type, but the images you would have to convert one at a time, and its becoming a bottle neck in our digital workflow.

Has anyone experienced this issue and have you come up with a solution?

thanks!!!

if the whole document is B&W, make sure you select GRAYSCALE.

if not, there's a BLACK DETECTION option in the Fiery driver

Black detection usually solves this problem for us.....

Have a wee read of the documentation for your rip. It'll explain all those options and I'm sure you'll be able to print blacks properly, amongst many other things.

Thanks, but we have tried all the rip settings, and black detection does not solve the issue.

Have you examined the PDF to mark sure you actually have a pure black like you think you do?

**bgardner** · 05-20-2011, 12:31 PM

Yes I have - CMYK mode, and just 100% K

Then is it possible that you've set the RIP to assume a profile for CMYK that is different from your destination profile? I would think pure black would be treated specially, but that doesn't have to be the case. Does the Fiery RIP have a preserve black option?

Black comes out of InDesign as Separation black. You can use PitStop or callas to convert Separation Black to K of CMYK (which separation black really is already) or to device gray. I've had this problem for years with Konica, Xerox and others. The only reliable way I have been able to fix it is to convert all blacks to device gray as part of the preflight/prep process.
