"He who marches out of step hears another drum." ~ Ken Kesey
I almost wonder if the pressure is so high that the squeegee is bending to the point of skimming over the image and not actually pushing or sheering ink through it.
For everyone mentioning the pressure, when workhorse installed our machine they mentioned to me that white inks should be about 80 and everything else about 60. I'm not sure if it's the way they set up the machines that it doesn't transfer over to the same pressures on an M&R machine. Sounds goofy, but my M&R buddies told me to try it at 30psi and it looks like the squeegee just wipes over the screen.I've always wondered about that as well.
