Hi All-

The project is moving forward albeit with some delays in the decision making process stateside relative to sizes and packaging. We are on track but if I had my way, we would move faster. These will actually be pretty nice units; all custom tooled from the ground up. I like that as it gave us the opportunity to design out some of the more frustrating features that their focus group has complained about while shaving off the excess fat in the right places (i.e. - not letting the accounting guys go nuts after we finish the engineering).

I have a couple of specific questions that I would like to address to Mech and Prof- Mostly related to the actual screen color and gain.

• What sort of spectrometer are you using or do you prefer? It looks like a PC integrated unit and I am interested in picking up a new one. We have a Minolta which is used by our QA group now and I do not want to pull it out of service and go through a painful calibration and standards validation session on existing products. Also, I am not all that tickled with the thing to be honest. I hear that there are better, less expensive computer based color spectrometry sets out there now.
• Does anyone know of a good source for RGB or Munsell shades by number as compared to some of the more popular screens in the market – OR – as defined by those in the know to be “good” targets?
• There still seems to be a lot of confusion about accurately measuring screen gain which has lead to some rather heated debates within the project group. I have looked all over the web and high and low for a good resource about this and can not find anything I really trust. Do any of you know where I can find a good description of the equipment and methods required for accurate and meaningful gain measurements?
