Hi, I'm putting together an exhibit of 20 prints through a local art gallery. The prints are all 12"x18". Although I think the odds are low, we (the gallery and I) would like to leave the option open for a larger size. At 12"x18", the images are all 300 PPI and can bear scrutiny from inches away. At 24"x36", they'll do fine viewed from a few feet or further. I'm printing all the photos on Breathing Color's Vibrance Metallic paper. I don't have the equipment to print anything larger, so I'm looking for recommendations for a printing service that is dependable and can print on metallic paper. As I understand it, papers like Kodak Professional Endura produce even more striking results than printing on a metallic paper with inkjet dyes. Ideally, I'd also like a service that would mat and frame the image. The ones I've found through a quick search have very limited frame options that are usually fancier than what I'd like (a skinny black metal frame). If that becomes a problem, I might stipulate that the larger size option is for a print only. Of course, I could negotiate any options with a buyer (e.g. these images would do even better face mounted on acrylic). The biggest problem, of course, is that I can't really afford to go out and check out the quality of different printing services, which is why I'm asking for recommendations for someone trustworthy. I suspect there is a wealth of experience on this site.
