ABSTRACT:
A method for determining the volumetric capacity of a fluid metering roller is disclosed. A measured amount of ink is deposited onto the transfer surface of the roller and is then dispersed into the underlying cells. A sheet of low-absorbancy transfer material is spread over the roller and the ink deposit lying in the interface between the roller transfer surface and the impression sheet is spread by the application of a roller or scraper across the back side of the transfer paper. The engraved cells are filled by the excess ink as it spreads across the cell transfer surface. The area of the transfer paper impression is measured by overlaying the impression area with a transparent sheet of graph paper having grid lines of known spacing. The known quantity of ink deposited upon the transfer surface (in billions of cubic microns) is then divided by the measured area of the transfer impression (in square inches) with the quotient being the volumetric capacity of the roller in billions of cubic microns per square inch.
