A few weeks back new member AH Theater offered to send me samples of some of Goo Systems product for a review and testing. It should be noted that AH Theater is the largest reseller of Goo products in the US. Three samples were sent.
- CRT White Basecoat and Topcoat
- Digital Grey Basecoat and Topcoat
- Digital Grey Basecoat and Ultra Grey Topcoat
Since the samples were sent I upgraded my computers to Windows 7 which added a bit of a delay to the results. And while I am not completely done, I'm going to post what I have so far. I do not have the few photos that I've taken uploaded yet and I haven't finished gain readings either.
From their brochure:
Goo Systems was formed in 2000 by an electronics expert, a paint engineer and a marketing professional. Our company consists of an electronics division, and a display technology division. Shortly after it’s inception, Goo Systems successfully launched Screen Goo into the market bringing a unique option for users to create their own projection screens. Screen Goo’s unique ability to be applied to almost any paint-able surface has seen the product being used in myriad applications.
Screen Goo is a specially formatted, highly reflective acrylic paint, designed specifically for the video projection industry. Screen Goo acrylic paint allows one to transform any smooth paintable surface into a high performance projection screen. Screen Goo's performance reflects many years of research and development. It has the capacity to outperform most of the existing screen products in use today. Screen Goo is made from the highest grade acrylic available and contains no filler materials. Whether used in a professional, or home situation it's simple application, versatility, quality and variable gain characteristics are remarkable.
Spectrophotometer readings using a X-Rite i1Pro spectrophotmeter. There are two sets of readings. The first set is straight from the spectro utilizing it's own internal light source. The second set is comprised of grayscale and primary/secondary readings using my BenQ W5000 projector as a light source. The reference for the first readings is from an X-Rite Color Checker Photography card, the N5 value. This card is also utilized in gray balancing (I like to call it color balancing) the photo images. It is the most accurate way that I am able to get accurate color reproduction in a photograph. The reference in the second set of readings will be readings from the projector itself. Normally I like to use my Colormunki to get the grayscale readings. But as I noted above, I just installed Windows 7 and I hadn't had time to get it profiled with my i1pro yet.
Gain readings are done with a block of Magnesium Carbonate as a reference. The instrument used to get these results is a Sekonic L758C spot photometer. The gain readings will consist of just a simple on axis reading and then I'll attempt to find the half gain angle. From the small amount of time that I have looked at these samples I don't think there will be a viewing cone issue. They don't appear to have any gain at all. We'll find out Monday night.
