Digital BW, The Print

Hi all,

Recently, we have heard mention of several different tpes of glass. At
least:
* Glass (the normal kind)
* Glass [green tinted] (the kind to avoid)
* Anti-glare (I thought this required to be in-contact with the print, and
therefore A Bad Thing???)
* Plexi-glass (presumably, 'Plastic Flexible 'glass'??? - is nice and
light-weight)
* UV Blocking glass
* No Glass!!!
* others???

I realise that these are 'characteristics' or properties of a material that
may be mutually exclusive, or shared in some cases. e.g. Does plexi block
UV?

I was recently told that 'normal' glass blocks about 42% of UV light. How
much does 'UV blocking' glass block? And how much more expensive than normal
glass is it?

I'd really appreciate some feedback on this to appreciate if I am correct
about anti-glare being something you have to place on the print... if when I
ask for UV-blocking glass, I am really asking for plexi (does plexi scratch
more easily than 'glass'?)

Is UV-blocking worth it for mormally mounted prints? Is it worth it for shop
window-mounted?

etc.

All feedback appreciated!

Happy printing,
Nij
