Very though-provoking article. Would like very much to do this. Quick questions:
1) do you buy COAs or make your own?
2) if you buy, where’s a good source to get them?
I’ve been wanting to use Hahnemuhle’s for awhile because they’re holographic and can be registered online directly with Hahnemuhle. What are your opinions on this?
Hahnemuhle makes a good product. It is expensive, and I’m not sure if the customers
see that the expense is worthwhile. Might be a good idea to ask the same question on the the fine art repro
group and see what people say.
