  Copy detection pattern (CDP) is a novel solution for products' protection
against counterfeiting, which gains its popularity in recent years. CDP
attracts the anti-counterfeiting industry due to its numerous benefits in
comparison to alternative protection techniques. Besides its attractiveness,
there is an essential gap in the fundamental analysis of CDP authentication
performance in large-scale industrial applications. It concerns variability of
CDP parameters under different production conditions that include a type of
printer, substrate, printing resolution, etc. Since digital off-set printing
represents great flexibility in terms of product personalized in comparison
with traditional off-set printing, it looks very interesting to address the
above concerns for digital off-set printers that are used by several companies
for the CDP protection of physical objects. In this paper, we thoroughly
investigate certain factors impacting CDP. The experimental results obtained
during our study reveal some previously unknown results and raise new and even
more challenging questions. The results prove that it is a matter of great
importance to choose carefully the substrate or printer for CDP production.
This paper presents a new dataset produced by two industrial HP Indigo
printers. The similarity between printed CDP and the digital templates, from
which they have been produced, is chosen as a simple measure in our study. We
found several particularities that might be of interest for large-scale
industrial applications.
