The image is printed by forcing ink through the stencil openings and onto the substrate. The image and non-image areas of the plate are each defined by differing physicochemical properties. Relief plates used in letterpress and flexographic printing have raised areas that pick ink up from the inking source. Neither of these processes can be used to print a true continuous-tone photograph (i.e., a photograph with intermediate or graduated tones) though halftone can achieve the illusion of continuous tones.

Lithography, currently the dominant printing technology, is an indirect (offset) process. Diazo oxides such as pyridol[1,2-a]benzimidazol-8-yl-3(4H)-diazo-4(3H)-oxo-1-naphthalenesulfonate are also used (Kirk-Othmer). The gravure press averages fewer web breaks than an offset press.

Diazos are not usually affected by temperature and relative humidity and have a relatively long storage life. What distinguishes microprinting is the fact that one generally needs to use magnification to read it. Join the world's largest stamp collecting organization | Exclusive benefits! On a gravure press, a higher page-count book can be printed in one press run with one press make-ready, while offset would require the book to be printed as a number of press forms with multiple make-readies and press runs.

The transfer roll is then hardened (tempered) and used to transfer the design into a softened (untempered) steel plate up to the desired number of subjects (Figure 11).
