A Comparative Study on Analog and Digital Printing Systems Performances
Several paper grades were used (mainly matt and glossy coated papers). With the offset process as a reference, the goal was to characterize print rendering for each printing technique by means of colorimetric and densitometric quality parameters. In the first class, we find:
- color gamut volumes, in order to decide whether (and to which extent) the standard quadrichromic offset process reproducible colors are included within the borders of the other gamuts or not,
- color L*a*b* coordinates associated to primaries and to their combinations and corresponding to the same CMYK set of values in the original computer file.
The densitometric measurements were : solid density, dot gain, and relative contrast index.
With the help of a novel method, we can exploit the whole necessary set of informations to automatically calculate all the above figures from experimental data using an IT8-7.3 test chart. This leads to a possibility to classify printing systems at least qualitatively: the results show the offset paper has the smallest performance of all the tested systems.

For more than 30 years, IS&T's series of digital printing conferences have been the leading forum for discussion of advances and new directions in 2D and 3D printing technologies. A comprehensive, industry-wide conference that brings together industry and academia, this meeting includes all aspects of the hardware, materials, software, images, and applications associated with digital printing systems?particularly those involved with additive manufacturing and fabrication?including bio-printing, printed electronics, page-wide, drop-on-demand, desktop and continuous ink jet, toner-based systems, and production digital printing, as well as the engineering capability, optimization, and science involved in these fields. In 2016, the conference changed its name formally to Printing for Fabrication to better reflect the content of the meeting and the evolving technology of printing.
