!!! make sure show this in RGB and make on-screen proof in RGB, otherwise diffferent settings can cause different results (you have to convert CMYK->RGB before post on screen proof otherwise you need Serendipity, Dalim or similar s/w)

Some error situations (wrong grey balance, cannot see 95% of Cyan etc) and instructions how to adjust monitor if something is wrong (some small videos would be fine) Some different well known colors - like Milka, Coca-cola etc Light and dark CMYK patches (with text - you have to see them and to see difference) Grey patches in at least 25,50,75% side by side (or similar) Just put on screen some grey and CMYK patches with descriptions Keep it simple, cause otherwise we will come to real monitor calibration.Ĭlaim - you do not give any warranty on such calibration method The human eye is too adaptive to change for vision to be part of a critical color calibration system.

Summary: Real monitor calibration and profile building requires a device more sensitive than human vision. Using that concept, inexpensive colorimeters could be purchased and periodically placed over a monitor for a Java based web app to communicate with.Īt the end of the day, who cares if it is web based, or local - considering that the real cost is in the colorimeter? This is also true of the medical field where doctors view results - but typically do not perform their hardware calibration. Several high end displays have built in colorimeters and will calibrate remotely upon an administrator's instruction. A less expensive colorimeter will typically produce equal or sometimes even better results.

Photoshop and other pieces of the Adobe Creative Suite do.)Ĭalibration and profiling can use either a spectrophotometer or a colorimeter.Ī spectro sometimes reads too many samples and then the software errors in its averaging algorithms. Monitor calibration is based on the following:ġ) Building unique look up table for the video card - Assists in creating linear gray balance as well as targeting colors within the monitor's gamutĢ) Brightness Normalization - Specific to a room's brightness and image representation (brighter for brightly lit rooms, brighter for web purposes, darker for print simulation or darker for a dimly lit room)ģ) Contrast - Usually 2.2 Gamma or L* for those who critically judge contrast stepsĤ) ICC Profile - When used in combination with the above 3 calibrations, will produce the best viewing result - IF - the image software calls the ICC profile into use.
