Sažetak
This paper presents research on the influence of polycaprolactone (PCL) nanocomposite overprint coating on the color change of offset printed paperboard. To investigate this issue color test card was developed via spectrophotometric software and offset printed on paperboard. The color values of the printed sample were measured before and after the coating application to facilitate the measurement and comparison of the results. The coatings applied on the printed sample were three different concentrations (1%, 2% and 3%) of silica nanoparticles in PCL biopolymer. The research found a color change in all investigated samples. It is observed that adding silica nanoparticles to PCL coatings improve the color stability of the coated samples. Detailed analysis of hue (ΔH), chroma (ΔC) and lightness (ΔL) of the tested samples show that PCL coating with 2% silica nanopartices result in the least amount of color change.
