ICC profile for Adobe RGB 1998 color space

Brad Gom , Apr 11, 2001; 07:41 p.m.

I'm really getting bogged down with this color management stuff.. I've hardware calibrated my monitor, scanned a Q60 target to generate a profile for my scanner, and written some software to apply ICC profiles to my raw scanned images. Now all I need is an ICC profile for the adobe RGB98 color space so I can use my software to convert my images from scanner space to RGB98 space. Does anyone know where I can get this profile, or how I could generate it? Note- I'm not using Photoshop which would presumeably do this conversion for me.

If you are serious about coding, then we should talk... I'm working on a free color calibration package for Unix - see www.scarse.org. It already does some of the things you want...

If you just want the profile, email me, and I'll make one for you.

You don't need to--and shouldn't--make a profile. Use the one that comes with Photoshop! In practical terms a color space is a profile once you're working on a computer (technically the profile just describes the color space, but on a computer that's the way you use a color space).

You can save the ICC Profile right out of Photshop by going to the color setup menu clicking in Adobe RGB 1998 as your RGB workspace and click on the "save" button, that allows you to save the Colorspace as an ICC profile. It will work for any colorspace as a matter of fact.

The orignal poster was not using Photoshop, so Photoshop suggestions will not help. My question would be what is he using to edit his images and does that software support ICC profiles. If so it should do the conversion. If he is not editing his scans, what is he doing with them.

Thanks for the answers so far, particularly to Andrei Frolov who has posted links to common profiles on his Scarse pages. To clarify, I am using ColorVision hardware to calibrate my monitor and provide color management for the entire Windows system. This way any program I use will display graphics with the right colorspace calibration. I don't trust the Nikon software that came with my LS-2000 to properly apply a correct scanner profile, or Corel PhotoPaint 8 to correctly deal with working spaces or output profiles. The lab suggested RGB98 as a working space that matches the capabilities of their LightJet printer. So- my idea is to use my own program to apply my Q60-generated scanner profile to all of my scanned images, and convert them to the proper working space. Then, with my monitor calibrated to RGB98, I can edit my files with whatever software I want and if it looks good on screen, it will look good in print. Any suggestions?

maybe i'm missing something, but i thought all the scarse stuff was for unix only? how will it help u (or me!)in windows?

I'll answer that :)... Scarse compiles and runs under Unix, but generated profiles are platform-independent and can be used with any Windows software.

Just in case anyone looks this up, the definition of Adobe RGB can be found here:
