The engraved cylinder is the most complex aspect of the gravure printing process. There are not many variables that can be adjusted on press, so there is a heavy reliance on the quality of the engravings themselves to produce quality print. This research seeks to answer the question: What are the components of the structure of an engraved cell and how do they affect the quality of a printed work; also, what technologies can engravers utilize to control cell structure? With the knowledge of how the structure of an engraved cell performs when printed, the engraved cylinder can be adjusted to ensure the highest print quality. This paper will define the variables of cell structure, and distinguish the many cell types according to the variables controlled. It will also describe the various cylinder-engraving technologies used to produce these cell types to better describe how the engraver can control cell structure variables.
