H/W Monitor Calibration

From: "Paul"

Anyone familiar with the ViewOpen monitor calibration system. I picked one up on eBay, although it appears to work fine on my system, Photoshop reports tat the icc file produced is not a valid RGB profile.

If you’re using Windows right-click on the file name, select ‘properties’ and see if it says "Type of file: ICC Profile". If it doesn’t then the file was probably generated wrong.

Does Windows assign this file as the default monitor profile? Check this by right-clicking on the open desktop and Properties > Settings > Advanced > Color Management and see if the profile is picked up as associated with the monitor. I’m not familar with your software but this is typically done automagically with Monaco or ColorVision or Gretag calibration software.

If the profile is picked up correctly then Photoshop should see it. If not on the list of "Color profiles currently associated with this device" then click the ‘add’ tab and try to add it. If you can’t then for sure the profile was not generated right.

Photoshop reports
that the icc file produced is not a valid RGB profile.

When exactly do you get this message? Are you trying to assign the profile or convert to it or something?

Let us know what you see with the two checks above.

Thanks for the reply

The properties of the profile say its an ICC Profile, when viewopen generates the profile it puts in the windows default profile directory, I then assign it as the default for the graphics card. At this point everything as worked as expected where I am getting the error is when I start Photoshop, it reports the default monitor profile is not a valid RGB icc file.

Maybe Photoshop is rejecting the profile because it doesn’t think the white point defined by the cal package is set correctly, I dunno. Worth passing this Q on to the Adobe forum. I bring this up because of a section from "Real World Photoshop" called ‘Disappearing Monitor Profiles’. Here’s the exact quote:

<quote from "RW Photoshop 6" by Blatner et al, pg 145> "Photoshop contains code that tests monitor profiles, and falls back to the default monitor profile … if the profile fails to map white to something reasonable close to white. Thomas Knoll … added this code to deal with some Apple software that occasionally created really bad monitor profiles, turning users’ displays very yellow … users blamed Photoshop … Unless you’re using an older version of Apple’s Default Calibrator, or a very wonky third-party calibration package, you’re unlikely to run into this problem …" </quote>

Nothing personal, but since I’ve never heard of the ViewOpen profiling software you "picked up on eBay" and are using to generate the profile it *might* qualify as a "very wonky third-party calibration package" 🙂

At any rate you might be able to mail the profile to Adobe and have them check this for you.

Otherwise if the system is seeing the profile correctly I don’t know why Photoshop doesn’t.

An older version of ViewOpen had a bug generating display profiles. Updating the software should resolve it.

Is their a fix for this problem or is it a piece of junk and I got what I paid for.

Thanks for any help

Hi Chris

Thanks for the info, I don’t suppose you have a link for downloading the update, as their is no support option on the Heidelberg site and google has found nothing for any updates.

Paul

Nope, sorry.
