I was talking to Matt from Westix Equipment and Supply about how a lot of my aluminum frames are warped and don't lay flat. He told me how to fix them and I thought I'd share it here:
- Take your warped screen and lay it down on the glass of your exposure unit or a table that is truly flat, noticing which corners (two opposite corners) stick up a little bit and allow it to the wobble on a flat surface.
- Hold the screen by the corners selected in the above step and lean it against a table or the wall or something sturdy, putting one of the good corners against the ground and the other opposite good corner against the wall or the table or what-have-you, at an angle.
- Press the warped corners. I tried pressing hard, but actually what seemed to work was little shoves of good force. Do a shove, lay it on the exposure unit, does it lay flat? If it didn't lay flat, I did another shove of the warped corners, until it did lay flat.
