Calibration vs Profiling

[Anonymous]

I have a client that asked me to look at some of his displays. His company is the distributor for Pvision displays in South Afica. He has sold a number of LCD/LED displays to a major fast food outlet and they are used to display the menu and prices. His client has complained that the images all look different. Initially I thought that calibrating the screens would be the solution so I tried a few. I calibrated three of his screens but that hasn’t solved the problem.

The problem is the same we experience when clients hand us their PowerPoint presentation at an event. The presentation was created on their laptop at home and then given to us on a memory stick. The colors on screen seldom match the colors on their laptop even with a calibrated projector or display panel.

I became aware of profiling while searching for a solution to this problem. It seems that the graphics and printing industry sorted this out long ago. They are able to get a printed document to match the color on their screen.

After more research I found that the X-Rite i1 I bought on the THX course can be used with X-Rite software to create an ICC profile. This profile is then loaded into the Color Management System in Windows. I have spent days trying to get this to work and it finally does look like the issue is able to resolved this way.

I have very limited experience, about a week, and have a number of questions and observations relating to profiling. Is there anyone on this forum that has experience profiling displays and projectors?

I do this for some of the post houses. I use my colormunki with the xrite software to do the profiles on the macs and PCs … and then I check it with my jeti spectro. The work stations often have two pc monitors and one broadcast type display … panasonic or sony or whatever. I do the manual calibration there and everything lines up.

I have already verified that my munki is tracking my jeti.

This profiling only works on grayscale stuff. It does little for color gamuts where external LUT boxes are needed. If the set up does not interface with the computer’s ICC profile, then this won’t work.
