In recent years, digital print engines have made marked strides in increasing their level of image quality. What was once a ragged, de-saturated, and uninspiring color document can now be made sharp and vibrant. The difference between the image quality of digital printers relative to offset lithographic presses is shrinking—but just how big is this difference? What particular image quality parameters contribute most to this difference? And how much does this difference matter to the end user? The objective of this research was to answer these questions by evaluating the image quality gap between digital print technologies and offset lithography and determining the importance of this gap to end users. It was found that there were significant differences in perceived value of prints made on digital versus offset printing equipment, with the prints on coated media from offset equipment being generally preferred and the prints on uncoated media from digital printers being generally preferred.
