PRODUCTION OF FOIL EFFECT ON METALIZED BOARDS WITH DIGITAL PRINTING PROCESS

A study of production of foil effect on metalized boards was done and the measurement of the reflectivity of printed metallic boards was performed. A psychophysical property for this percept was identified as visual brilliance. The visual judgments of a series of printed boards were compared with measurements from various types of specular reflectance instruments. The results showed that gloss linearly follows the appearance of highly reflective specular surfaces. It was observed that the foil effect was highly related to the incorporation of primer coating on to the metalized board normalized. Further, It was, thus, concluded that foiling effect can be produced on a metalized board by printing it with a dry toner based digital printing process without primer coat
