With the SEAL press the top part (with the heating element in it ) swings down to the base ( with that felt spacing ) to give the Print, tissue and mounting board sufficient pressure to bond the print with heat and pressure. You may replace the felt but the swing should be re-adjusted to give the correct tension. When I dry-mount with my Seal press I have a large piece of Photo background paper folded in two in which I place my Print. From top to bottom I have :- Background paper, mat board or release tissue, then print, tissue , backing board (all 3 tackked together ) then another backing board then the other piece of that background paper. It is all assembled , put in place in the press , the press closed down for 60 seconds, removed, then the print placed under a large piece of 1/2" glass until it cools, usually this is in time for the next print to be cooled. Using this method the emulsion face of my prints only come in contact with either my release paper or the clean piece of matt board.
