In recent years, there has been substantial progress in the quality of printing inks. This is mainly due to the improvement of the tolerance to light exposure and weather exposure of the printed products. The advanced methods of lightfastness and weatherability testing is also an important factor of the enhancement.As far as a printed product is concerned, the means of refraining its colors from fading when exposed to the lights of nature and surrounding environment shall be a factor of importance in pursuing the quality of printing, which is directly effected by the production formula of printing inks and whether the components of the paper is of high quality. In this article, we will discuss the different methods of lightfastness testing and the type of light source, and mention the testing methods and specifications of ISO, AATCC in regard to lightfastness and weatherability testing. Finally in this article, will discuss the methods for analyzing lightfastness and weatherability so that you may have a better understanding of lightfastness and weatherability testing methods. |
