I've just realized that my screen has been (very) badly calibrated for a long time, despite the fact that I calibrate my pc on a regular basis :( A printer firm has recommended me to buy a 'One Eye Match' device, and I would like to know, before I consider buying it, if anyone here is familiar with it and if it is worth buying at all ?
