Paper is porous? Who’da thunk…

Using the second 6-axis robot to move paper in and out of the ‘graffiti pad’ in proving much more difficult than we thought…We are using 4 suction cups pulling ~10psi of vacuum to grip the paper, and instead of picking up one sheet at a time we’re lifting the whole stack!  The solution? – Use photo paper because it’s much less porous!  I probably should have thought of this before buying 500 sheets of 110lb cardstock.
