After watching a YouTube video on photo printing and framing, I decided to try using frames without the acrylic 'glass'. The thin mounts that come with my preferred skinny metal frames warp a little wihtout the acrylic (understandably). So, I tried Cadremount's extra think mounts - with success! Very pleased with the results.
I have also used anti-glare acrylic which is also much better than the original acrylic.
