Rotogravure Printing
This chapter describes the rotogravure printing process. The process involves transferring ink, one color at a time, from a cylinder in which a pattern of cells has been engraved to a substrate. Additional colors, each registered to the locations of those printing previously, are added. This multicolored pattern of inks dots on the substrate takes on photographic quality with the halftone printing effect. Dot patterns can combine to appear to the eye to be colors not present in the applied ink. Ink metering involves a doctor blade assembly that wipes excess ink amounts from the cylinder surface to provide careful control of the volume of ink transferred from each cell.
