As a major distributor of parts and consumables for ink and toner based imaging systems, assessment of source materials is a priority in vendor selection, qualification and on-going quality control. The sheer volume of prints necessary for comprehensive analysis is prohibitive when it comes to manual measurement or visual inspection.In order to provide the best quality products and to improve our internal tracking and communication, we have updated our inspection process to include automation of image quality measurement.Working with a test equipment supplier, we have integrated a flatbed scanner-based system into our process that we use in conjunction with specialized color and density measurement equipment to provide a wide range of image quality measurements for both toner and ink based prints.This move toward automated, instrumented analysis has improved the efficiency and repeatability of our inspections, and has enabled us to comply with industry-standard measurement methodology. In addition, the new system has allowed us to increase our throughput while providing us with a wider range of analytical data specific to each printing technology.This paper will detail several of our assessment methods for both toner and ink-based prints, and will discuss the benefits we have achieved as a result of implementing these new processes into our workflow.
