Sažetak
The flexographic technology is frequently used for printing polymer substrates and the lightfastness and weatherfastness of obtained prints is extremely important. The lightfastness and weatherfastness of prints is an ability to retain their color strength and resist fading upon exposure to sunlight. Prints with low lightfastness and weatherfastness have negative effect for sellers of various goods labeled with polymer material. It is well known that numerous polymer labels on packages are often placed on the shelves in the market where these prints are more or less exposed to sunlight and the only protection are windows. Analyses of lightfastness and weatherfastness of overprint patterns was established according to standard ISO 12040, where prints were exposed to light from Xenon lamp only and to the combination of light from Xenon lamp with added artificial rain.
