POE film printing adhesion poor
Sorun Belirtisi
POE film ink adhesion after printing
Neden Analizi
POE surface polarity has poor affinity with ink; corona treatment effect decays quickly; ink system does not match POE
Çözüm
1) Print immediately after corona treatment, within 24h; 2) Use POE-specific ink; 3) Increase corona power to 15-20kW/m² to ensure surface tension >42mN/m; 4) Flame treatment to assist surface polarization
Temel Çıkarım
Poor printing adhesion is caused by insufficient surface polarity; corona treatment and special ink are key
