Hi,

after posting on ICC profiles, I realized (via several online documents) that the first step is actually, to calibrate the monitor. I found two tutorials on this, but when trying to calibrate my Fujitsu-Siemens monitor (Scaleoview 19-2 TFT) by using the first tutorial at scarse.org, I had to realize that this didn't work at all. After checking the system gamma and correcting it according to the patterns at the site

see http://www.scarse.org/adjust/

I wasn't able to set either black (http://www.scarse.org/adjust/black.html) or white (http://www.scarse.org/adjust/white.html) point. They are simply out of the range of what I can adjust via the OSD (On-Screen Display). Now I am asking myself if this tutorial is probably only for CRTs. I then tried another tutorial by Norman Koren at

http://www.normankoren.com/makingfineprints1A.html

This seems to be much better, and he mentions a variety of other online sources with test images, software for calibration/ gamma correction, etc.

But when trying to correct the gamma of my system, I got two different correction values (monitor: see above; OS: Ubuntu 8.10/i386):

1.4 (http://www.scarse.org/adjust/gamma.html) 1.4 (http://www.normankoren.com/makingfineprints1A.html#gammachart)

1.76 (LProf -> http://lprof.sourceforge.net/)

My question: What is the proper correction value? 1.4?

Does anyone know what the differences between calibrating CRTs and TFTs are?

Those issues aside, I find the topic very exciting.

For those interested, here are a few recommendable sites I came across:

- http://www.scarse.org/adjust/ (see above) - http://www.normankoren.com/makingfineprints1A.html (see above) - http://www.digitaldog.net/tips/index.shtml (reference images & more) - http://www.eci.org/doku.php?id=en:start (ICC profiles for offset printing, docs on the proper use of PDF, etc. - http://lprof.sourceforge.net/ (calibration software for Linux) - http://docs.scribus.net/index.php?lang=en&page=moncal (LProf HOWTO at the Scribus site)

Cheers,
