| The success of waterless planography is dependent upon there being a low free surface energy polymer overlaying the non-print areas of the printing plate. |
| Planography, any printing technique in which the printing and nonprinting areas of the plate are in a single plane, i.e., at the same level. |
| Planography is the primary process employed in present printing systems because plate preparation is inexpensive yet allows for high printing quality. |
| For purposes of reproduction, lithographic planography was rapidly introduced on a worldwide scale once it had been invented. |
