Abstract
A method of generating a diagnostic plot for a printing system includes printing a first half of a diagnostic pattern representative of a first state of the printing system, and printing a second half of the diagnostic pattern representative of a second state of the printing system. Variation of the diagnostic pattern from an adjacent diagnostic pattern indicates the printing system is out of specification.
Claims14
A method of generating a diagnostic plot for a printing system, comprising:
- printing a first half of a diagnostic pattern representative of a first state of the printing system;
- printing a second half of the diagnostic pattern representative of a second state of the printing system;
- wherein variation of the diagnostic pattern from an adjacent diagnostic pattern indicates the printing system is out of specification, and
- wherein the diagnostic pattern includes adjacent horizontal lines, and the variation of the diagnostic pattern comprises a change in pattern of alignment of the horizontal lines including one of a change from a step up pattern of the horizontal lines to a step down pattern of the horizontal lines and a change from a step down pattern of the horizontal lines to a step up pattern of the horizontal lines.
