copper/glass laminating 1

I must laminate a 22 inch by 24 inch 1mm thick (16 oz) copper sheet to 3/16 inch glass that is also 22 inch by 24 inch. It must be of an adhesive of optical quality and withstand environmental changes of a sun exposed hotel lobby. It will first go through a ferric chloride bath.
I cannot have airbubbles. Is there machinery I can buy/built to make these panels. Laminators aren't wanting to touch this.
I would like to do it. I have tried 4 inch by 6 inch pieces, in a vacuum bag (makes more bubbles), 20 ton hydrolic press and small 1 inch thick steel platens (pushed out all adhesive), manual pressure (better results), and with no pressure-just lowered copper at an angle trying not to trap air.
I am currently using a UV cure so that I am not stirring in bubbles.
I am using Mayer/coating rods to apply adhesive.
This will eventually be a manufacturing business, but I am doing custom work now. Any suggestions appreciated.

The 1 mm thickness may not be practical - the thermal expansion of Cu doesn't match the one of glass. I would suggest using chemical deposition to put a THIN layer of Cu
on the glass and then cover it with e.g. Cr. or lacquer.

The deposition is used in the art of printed circuit board
MFG: clean, pretreat it with Palladium chloride and then
deposit the Cu from CuS04 + NaOH + tartaric acid complex solution by reducing it with formaldehyde.
