Poor Printing Adhesion of CMC Film
ظاهرة المشكلة
After printing on CMC film, ink adhesion is
تحليل الأسباب
CMC surface polarity has poor affinity with ink; corona treatment effect decays quickly; ink system does not match CMC
الحل
1)Print immediately after corona treatment within 24h; 2)Use CMC-specific ink; 3)Increase corona power to 15-20kW/m² to ensure surface tension >42mN/m; 4)Flame treatment to assist surface polarization
الخلاصة الأساسية
Poor printing adhesion is caused by insufficient surface polarity; corona treatment and special ink are the key
