first of all excuse my ignorance on the topic of profiling...

Kodak approval is our benchmark.

Want to match all of other devices (hp, epson, xerox's) to the approval.

We have Colorblind software along with profilemaker 5.0 software

Proofed it8 target on the approval to get our benchmark.

do we then get readings off of this target and use profile when proofing same target off of other devices and adjust from there?

or do we proof target on the other devices with all color management turned off and start at that point?

HELP????

thanks in advance.

Output your target on all the proofing devices with no profile attached (you want to see where it's at without any changes), read the target in to create the profile of the device. You now have a destination profile.

When you print to the Xerox (for example), use this in your color management setting:
Source: your approval.icc
Destination: xerox.icc

should be good to go,

just so i am on the same page.

on all devices my source profile would be the approval since that is my benchmark correct?

Color Mangement can be confusing. I highly recommend buying this book, it will help you tremendously.

"Real World Color Management" by Fraser, Murphy & Blunting.

Yes, you are correct.

Have we assumed that the Approval is color matched to your presses?

This may be a faulty decision to match to a proofer. If the Approval goes "Out" of calibration, then you may be chasing your tail if things go AWOL. Perhaps the best choice might be to profile to a repeatable device and I always pick a press rather than a piece of electronics...IMO.

The only thing we print are ad reprints and topsheets. 99.9% of work are ads which we ship out to publication. We take readings every morning and afternoon for our two approvals to make sure the densities and lab values are correct. If we printed everything we produced, I would agree with you, but we don't and we have never had a problem matching our proofs on press.

We recently installed the EFI Colorproof XF v2.6 rip.

One of our hps (designjet 800 series).

We read our benchmark approval target and generated an icc profile using monaco profiler. Then we read the same target printed from the hp (all color management turned off) generated an icc profile for that target.

The question I have is when using the EFI rip there are two areas you can choose your profiles when using color management:

Source and Simulation.

First tried: the profile for the approval as the Source and profile for the designjet as the simulation.....horrible results.

Second tried reversing the settings....not much better results.

Should either of the two settings have "none" selected?

The best results we had was manually adjusting the color through curves, but really don't want to go this route.

thanks in advance for any advice

A Color Management conversion can happen in your software when printing, your print driver or at the RIP

You setup has the color management conversion happening at the RIP. You need to make sure that no color management conversions are happening in your software when printing to your RIP or your print driver.

You could be getting multiple conversions which is screwing things up.

From my experience, a Kodak Approval is WAY more stable and repeatable in every regard compared to a press. Not that I think its a bad decision to use a press as your aim, I just don't a stable halftone proofer is a faulty choice for a target.
