I really did have a hectic day at work, I thought I was going to be able to get this converted to web friendly presentations and get it up here sooner.
Here is the raw data. I know a few people out there may be more interested in this than charts and graphs.
Next let's look at the RGB graph. This shows the color linearity of the samples. Most are showing very similar characteristics to those of manufactured screens.
Let's compare this chart with Prof's original color swatch data that I converted to a graph as well. This chart has actual manufactured screens as well as some DIY paint data. This is a nice comparison of the color values to the Wilsonart colors.
This next graph is one that is going to have a lot of people's attention, it is a gain comparison. StudioTek 130 and The Grayhawk are also shown on this graph for comparison purposes.
The Wilsonart Grey actually has better gain characteristics than the Grayhawk, and Designer White is giving the ST130 a run for it's money as well, but not quite there. What makes this graph important is the inclusion of actual manufactured screens. Now we can see actual side by side data comparisons with a tangible item, no guessing or speculation. We need more data like this, for both paints and commercial screens.
The last plot shows which direction any color push is in. This is for comparison purposes to get an idea of what color is being pushed and how much more than another sample.
I want to sincerely thank Prof for lending all of us his time and equipment to give us some professional data. I think we are on the cusp of a new look at DIY. The gain graph alone adds credibility to any claims that were made so far on this thread, and I hope others start to gather and provide data. This will raise the bar across the board if others follow suit. This isn't an end though, it's just the beginning, more research and tests need to be done.
I would like to see some more data on Fashion Grey, and Platinum. All in good time though...
So here is the breakdown:Designer White D354-60
is the recommended color for a white screen and it has a gain of 1.24. This will be good for people with light control (or evening viewing). It will provide clean colors and a bright vibrant picture. Since it has a higher gain, there is a possibility for projector's with very high lumens to hot spot, but the projector should be able to compensate for this by decreasing the brightness some. It's almost a StudioTek that is virtually indestructible.Grey 1500-60
has a good color balance (202/191/191), and its lightness and gain is comparable with the Grayhawk. It has a gain of .94 on center, which is rather high for a gray screen(The Grayhawk is .84). The gain does drop off, but no more than the Grayhawk, in fact it is 'slightly' better at a 50 degree viewing angle than the Grayhawk.Dove Grey D92-60
is for people that like the dark gray that the Firehawk G2 has. Dove Grey is a little lighter than the G2, but much more neutral with a slight green deficiency. This one deserves some attention and testing for ambient light situations and with the right top coat mix this could rival the G2 at a fraction of the cost.Fashion Grey D381-60
is very close the same darkness as Silver Screen... When I held it up to my Silver Screen 'screen' it is very close to the same shade, but now we see with the data it is much more neutral than Silver Screen (FG - 195 188 194, SS - 207 202 215) and we see that same slight green deficiency that most manufactured screens exhibit. Silver Screen has this same deficiency as well, but has a blue push to it as well.
Fashion Grey and Platinum are sadly missing on the gain graph, but I will see if we can get some data and tests on that. This was a lot of work Prof did in a short period of time, so we should be Ecstatic with what we have and not nit pick and point out what wasn't included.
Just think, all of this data and good news and
as a screen this stuff is virtually indestructible!
To give everyone an idea of what may be coming, I also sent Formica samples, and several films that I thought looked interesting when placed over some of the laminates and Chromes. So for now we at least have a bonafide white (Designer) and a gray (Grey) that anyone should feel comfortable using. Then for darker grays we have Fashion Grey as a very close but more neutral SS alternative, Platinum comes in as darker than Fashion Grey, but lighter than Dove Grey, and as mentioned Dove Grey is for the G2 lovers out there. No it's not going to be exactly like a G2, but it could be close enough for some to be quite happy with.
This has been a long post but I think it was worth it. The last thing I want to bring up, and this will probably even excite the people that prefer paints over the laminates... with the data provided these colors can most likely be converted to a paint formula. I would also love to see some experimenting with the grays and paints... but all in good time!
I want to add something to all of this... no DIY method will usurp the professional screen world. I think some methods, both paint and material can rival and maybe even match or exceed the quality of cheaper low end manufactured screens, and some mixes may even be in the mid level mfg range... but let's face it if we could
match a high end screen with a hundred dollars or so of paint and or material, then they would be doing it too.
