I’m working on a public art project that will consist of 20 large photo transparencies applied to the interior windows of a community center. I’m looking for a durable transparency material that could withstand one or more years of exposure to heat and UV. Any suggestions on mediums or labs from photographers who have experience in this area would be greatly appreciated. In particular, any info on labs using RA4 process using Ilford or other acetate mediums would be helpful. I’ve explored duratran, duraclear and Roland adhesive vinyl with UV inkjet inks but I’m not sold on any of them yet.

Thanks for the knowledge. MM
