John (D),
you talk about pre-anodised sheets with photoresist applied. is this anodising applied or removed by a photographic process? how does it work? how do you make the color change?
sounds like a very intresting material for our purposes! hannes -- hannes kühtreiber [EMAIL PROTECTED] http://www.datenmull.at.tf --------------------------------------------------- https://lists.uni-koeln.de/mailman/listinfo/sundial
