Abstract
A method of analyzing the writing quality of a ball point pen for ink laydown, blobbing, and degree of inconsistency employs a computer and an image analysis software package capable of assembling a pixel gray level distribution known as a histogram. The distribution of pixel gray value for a writing sample is manipulated and analyzed, the values then being compared to a range of pre-established values.
