I thought there should be some "off contact" when placing the screen. Thanks for the conformation.Bart
I don't know what rasta bar is, but shims went out the window about 35 years ago for us. Most good manuals have an off-contact adjustment. Steve

SteveI still use shims on a back clamp manual. It's true that the press has off-contact adjustment....but....when you run the squeegee (push or pull), there is no way the back clamp can maintain the off-contact and the screen will drop down on the substrate effectively negating the off-contact setting. Possibly a side clamp press may not have this issue, but my back clamp Workhorse does. I simply cut up a thin yardstick into 10 or 12 inch lengths and tape to the underside of the screen front edge (and sometimes to the back edge also to avoid any issues with the arm flexing) so the screen frame maintains the desired off-contact through the entire stroke allowing the screen to do the "wave" laying down ink. I may be in the minority, but it's what I do.
I'm guessing that the M&R Rasta Bars were color coded in red, green and yellow as well
