John, Veena... Do your heat presses have a half inch thick rubber 'blanket' on the bottom plate? I have that, plus an old old teflon covered thin padded sheet that slides inside the shirts. The two 'rubber' cushions even out any off set to the top platen, and I read when I bought the replacement bottom sheet that the intial contact of the heated platen causes a quick expansion of the sheet-pressing the fabric up for full contact. Unless I get a folded collar in the way that holds the platen up, I don't even get off pressure problems with button neck shirts. It might also be my heat machine-it is around 35 years or older-solid steel-I'd guess it weighs in at over 75#. Takes 2 of us to move it and it is only a counter top 12 x 16 model! Roland
