Digital BW, The Print

hi, i'm new here. it seems to me that the best way to archive frame an
inkjet print is to use those little plastic corners that self-stick to
a mounting board. is that right?

if so, the next thing is, i should be leaving at least a 1" border of
paper around my print so that the corners don't come in contact with
the printed ink. am i doing well so far?

now basically when assembling a frame, matt and mounting board, these
things are just sandwiched together without any special gluing or sealing?

final question - what size corners does one use for 13x19 paper?

thanks
