The method described in this document arose from a need to identify, monitor and resolve different

contributors to print quality (PQ) defects for small‐format dye sub photo printers as well as other types

of printers, depending on the implementation. A variety of targets were tested to flag and measure the

extent of issues like linefeed error and skew, both of which are typical of inkjet printing. Measuring

those targets typically require high resolution scanners with custom software to plot linefeed and

different types of visible skew. However, other issues aren’ as easily detected, much less measured;

these include misregistration, banding, and roller marks. In order to make the solution more effective

for troubleshooting, added weight was given to streamlining the process to provide immediate feedback

to engineers and operators.
