This is all interesting information.
So what you are saying is to do this there would have to be some parameters met, which does make sense. What made me think of this was all the endless threads, some even ending in bickering and bad feelings between people that are all trying to do the same thing... duplicate a professional screen, and even improve upon it.
To me it just made sense that the first step logically would be to find out what they are doing. That seems easier than mixing this, mixing that... which sometimes sounds like nothing but a lot of hard work put into 'guessing'. No offense to all the efforts people have done with paint mixes, there has been a lot of hard work done... some has paid off... some has just been spinning wheels.
From reading the various posts, it does sound like there are some very knowledgeable people out there working on mixes, and they seem to know what they are talking about. Like I said, I was curious if anyone has tried to get a baseline from an actual manufacturers screen.
Prof just for the sake of fun here... since what you are saying about the gloss(reflective property) makes perfect sense, wouldn't trying to find the color mix used then concentrating on that 'secret ingredient' gloss (said tongue in cheek and smiling... remember this is intended as a fun thread) be logical? Once that is duplicated, then variations can be tried and applied in a much more controlled manner.
I understand most people are just trying to get an inexpensive screen up and don't really care whether they unlock the secrets of the screen universe. To them this thread is probably not of any interest, well... unless the end result actually comes up with something. I still say DIY to me is more about mating a screen that is optimized for one particular projector, that being the one the person owns.
Anyone reading through these forums has to admit though that there have been some pretty heated arguments at times, some even getting nasty about defending their particular mix over said other mix... yet I have never seen anyone mention having a baseline. That comment wasn't directed at anyone in particular, it was just an observation.
Okay nuff said about that, I don't want to go in a negative direction, like I've already said several times already, I thought this would be something fun to investigate... I am probably reinventing the wheel here myself (threadwise) but if this has been discussed and tried I haven't run into it yet.
