A small guide to the GSM index of a paper can be found below This combination results in a longevity of the print of up to 200 years so you won't have to worry about the picture fading out. I'm also accepting custom requests and can print a picture of your choice in Super A1, A2, A3, A3+ & A4 formats with a quality paper that I'm using (230 - 312GSM).
