Abstract
A testing procedure and method is provided for assessing the quality or acceptability of performance of individual liquid ink electrostatic toners on individual receptor surfaces. An approximately standard drop of the individual liquid toner is placed on the receptor to be tested. The drop is pressed onto the receptor and spread on the surface of the receptor (preferably before the drop has had time to partially evaporate or to have the liquid in the drop absorb or naturally spread on the receptor surface) under controlled conditions. The characteristics of the spread drop on the receptor surface are measured, and the characteristics are compared to parameters defining the characteristics expected from a liquid toner that define acceptable performance between toner and receptor. In this manner the relative performance of individual toners on individual receptor surfaces can be evaluated independent of electrostatic effects. This can be important, as the electrostatic effects bring another parameter of performance into evaluation of the compatibility of the toner and receptor and can misdirect research for adjusting their compatibility.
