Dear Ken,

I am sure you have an abundance of common sense......

The issue with Glass Plates is that I bet you would want lots and lots of different sizes and emulsions and the supply chain is very delicate and the packaging is custom made, coating on glass has a high QC waste factor per m2 as well, so the costs per plate would just not be viable to produce commercially. Holography is most certainly a larger market by m2 than conventional emulsions on glass.
