Opportunity is missed by most people because it is dressed in overalls and looks like work. - Thomas Edison
A certain man from Texas has talked about this forever. And. I'm almost 99% certain John Sheridan on here has modified a M&R press before to do this. Or posted instructions on how to.
Ah. I'm really sleep deprived today haha. 7 month old and a 14 year old lab up all night. Anyway, you can print either way then on M&R presses then as far as I know. That would be the fill / flood position for water base inks. We are in a high humidity environment and use thin thread so we print like plastisol though. But I do know that man from Texas modified his presses in Mexico to print with a "push" instead of a "pull."
