Comparison of Colorimetric Values of Prints Made with Cyan Ink on Different Polymer Materials

Flexographic printing process has been established as a very competitive printing method and a broadly used printing technique. Consequently, as a more demanding packaging printing has to be performed, flexographic printing process became a strong competition to the gravure printing process. It is a quality and cost-effective printing technique used in respect to various types of substrates. This research analysis was focused on testing flexographic prints on six different polymer materials. Namely, it is mandatory for good quality prints to have good coverage even at low film thicknesses when printed on the printing substrate and the previously printed ink film, respectively. Therefore, the acceptance of cyan ink to the different polymer printing substrates and acceptance to the previously applied white ink were analysed. A number of samples of cyan ink acceptance with various viscosities were compared with each other by using spectrophotometric values converted into colorimetric values L*, C*, h˚.
