I’ve noticed even while working there, that the prints going on the screen are off centered by 3/16”
When you print and measure inside the pusher frame, it’s dead center of pusher. I am no engineer, but I gather that the difference is a result of the 3/16” tri-loc nubs added to the outside of the frame area on the right of machine.
For those looking for dead center, in Color Print folder setups, just put in -.19 offset. It won’t do exactly .1875 so it rounds off.
This is especially important for pocket prints where you need to fit within.
