A Measure of Ink Jet Wicking and Bleed Properties Using a Document Scanner and Pc
The objective of the work described in this paper is to determine if a document scanner based image analysis system can be used to measure the printability of papers developed and marketed for use with ink jet printers. Document scanners as used in the personal computer based graphic arts are becoming commonplace in paper mills as a tool to measure residual ink and dirt. Some of these systems, often called “dirt counters”, have evolved into image analyzers and are quite capable of resolving images down to 42 µm in diameter and have gray scale value (GSV) resolutions of 1024 GSV. Their analysis capability includes false color image overlays for size measurement and sorting of features by size and average GSV(AGSV). These systems are robust, and have tools which can be used to measure two very important paper printability properties, wicking and bleed, quickly and easily in the production environment.
