Abstract
The invention relates to a process for automatically determining the image quality of inkjet photo printers or color inkjet photo printers, whereby a digital reference test chart is produced which is made available to the printer. The printer or photo printer prints out the reference test chart so that a photo printer specific printout of the reference test chart is generated, which is digitized for comparison of the digitized image data with an optimum digital reference test chart, for determination of the image quality of the printed image on the basis of deviations or concurrences between the photo printer specific test chart printout and the reference test chart.
