Monitoring of flexo UV inks and varnishes cure process

Popis výsledku v původním jazyce

The scope of this study was to evaluate the cure rate of commercially available flexo UV inks and varnishes by means of photocalorimetry and infrared spetroscopy (FTIR). The temperature dependency was monitored by photocalorimetry. With increasing temperature the curing speed decreased for both the radical and cationic systems. Induction period was approximately same for radical varnishes whereas diminished significantly with temperature in case of cationic systems. The cure degree in relation to UV explosure was evaluted from course FTIR spectra of raw, partialy and fully cured UV inks and varnishes samples. The initial results reveal green ink beeing cured more slowly than the others can effect print quality especially trap of overprints and make thepress hard to control. However, further experiment focused on overprints showed that when different light source is used the curability of green ink became similar to the others, thus suggesting that the initial light spectral power dist
