Is there any software that will calibrate a monitor available for Linux, so that you can more closely match what is seen on screen to what is printed?
Thanks,

Hi Fred I think that the answer will be that even if there is such a utility, you are likely to be disappointed with the outcome, unless you have a really bad printer. Just for fun, I tried in Win NT, years ago, to set the screen background to the same colour as the wall in my office. It was difficult, but on 24 bit colour I got very close, although a difference of 1 or 2 on a colour co-ordinate in 24 bit colour was noticeably wrong or different. Half an hour later, it looked all wrong. At night under artificial light, it was well wrong. I don't think NT or the monitor were drifting either. The explanation which satisfies me is that the monitor emits light at set absolute levels. The wall reflects whatever light it is given as relative levels on all 3 colour coordinates - relative to the colour balance of the incoming light which changes from hour to hour and between direct and indirct natural light and artificial light. Through evolutionary adaptation, we are adapted to varying incoming light and compensate for it, so that we see things which reflect light according mostly to the reflection co-efficients of the reflecting surface. ie, we filter out the variations in incoming light. With an experiment like mine with the wall and the monitor, something must give, and the monitor is perceived to be wrong, when 1] it isn't and 2] there is no way to put it 'right'. all the best Vince
