Printer Image Quality Testing


 We have extensive experience in quantifying the image quality of printing systems.  Image quality testing is typically done throughout a development cycle: from early prototypes through shipping approval.  Specifying IQ limits in a product requirements document is more complicated than other printer specifications due to the lack of accepted standards in the industry.  We understand how to communicate and verify IQ specifications to ensure that products are built to meet customer expectations.  Evaluation of printer IQ metrics typically follows the steps below.
