ABSTRACT:
A method and apparatus for rapidly determining the print quality of a porous material which includes contacting a porous surface with a source of ink, and then providing a known relative acceleration between the ink source and the porous surface. In this manner, a predetermined volume of ink is transferred from the ink source to a known area of the porous surface. Then, the amount of ink transferred into the porous surface area per unit of time is measured to thereby determine the time between initial ink contact and the initial ink penetration, referred to as the wetting delay, the penetration rate of ink into the porous surface, and the volumetric roughness of the porous material. All of these latter parameters are closely correlated to print quality.
