What is the problem of poor spray painting of semi-rigid PVC calendering film
The poor ink absorption of PVC calendering film is generally due to the following reasons: the poor ink absorption of PVC material itself, plus the smooth surface of PVC calendering advertising cloth, if it is to make fine patterns, the recent analysis of patterns is very poor, the image of PVC calendering film advertising inkjet is fuzzy, and the high-resolution image edges and corners are not imaged, generally PVC calendering film coating can solve this problem
It is possible that the ink does not match the film material; more likely, the ink absorption performance of the film material itself is not good. At present, additives can improve the ink absorption performance of the film material and prevent the release of plasticizers.
