Can anyone tell me just how many pounds of pressure are exerted while printing on Vandercook flatbed presses (SP-15) or indeed other models such as C&P platens?
Yes of course, thanks Paul. Your answer puts me in the ballpark for pressure issues on a Vandercook at least, thank you.
Square inches is not applicable because a platen exerts pressure over an area (the bed) as a single event, whereas a cylinder exerts pressure on a narrow, rolling point of contact. In other words, one can’t factor areas that are not effected by force.
Thanks for this Paul. Could one guess that all flatbed Vandercooks built along the same lines would exert similar pressure? Pardon my lack of comprehension here: 200lb lineal/would that mean the 200 gets divided by the width of the impression roller in inches? In this case 200 divided by 20 or 24 so approx 10 to 8.33PSI? Seems low?
A sales sheet for the 320/325 series Vandercook says it delivers 200 lbs. of pressure per lineal inch. I haven’t found a spec for the SP15.
