Glass Fibre film poor printing adhesion
Sorun Belirtisi
After Glass Fibre film printing, ink adhesion
Neden Analizi
Glass Fibre surface polarity has poor affinity with ink; corona treatment effect decays fast; ink system not matched with Glass Fibre
Çözüm
1) Print immediately within 24h after corona treatment; 2) use Glass Fibre dedicated ink; 3) raise 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 dedicated ink are key
