My Challenger prints that way. It works great except for the on the seam tramp stamps. For those I wish it went in the other direction. Other than that there is no difference in the way they print.

I've set our auto up to push stroke one day when I was bored.  It took me a while to get the squeegee settings just right.  I think that I could fabricate a squeegee that would print perfectly using the push stroke if I had time to sit down and think about it.  I didn't have the tools to measure ink deposit at the time I did the push stroke experiment but it seemed to me at the time that the ink desposit was significantly more.  If we ever slow down enough for me to have an hour to play around I'll mess around with pushing on the auto and actually measure the results this time.

I took the time to convert a formula head to print a push stroke when I was back in NY. It took awhile to switch some parts around but when I got it working, it was very finicky and to much squeegee pressure by even a single twist had the blade bending over. I did some printing with it for some 1/2 tone work and when I used a good tension screen, it did print some nice dots but nothing awesome or better than the head next to it pulling.

The older machines work wonders when you put high tension screens in them and parallel the pallets.
