I do enjoy printing on a Vandercook proof press! Cylinder presses allow for uniform pressure across the entire surface of the print because you only have a small portion of the cylinder touching the form at one given time. On a platen press you dispurse all the impact pressure across the entire plate which reduces the overall impact pressure on a large form. The drawbacks of using a hand crank proof press of any kind is speed. You need to account for many more hours behind the press on large jobs because there is no way that you would be able to keep up with a motorized platen press even if it is hand fed. To put it in perspective, I can hand feed 1100 impression per hour on my Chandler & Price 10 x 15 platen press. To hand crank a Vandercook I can only pull between 200 – 250 with accuracy.
