1.胶膜INK(油墨)可分为1C、2C、3C、4C,(C为Color首字母);外观主要区别可从油墨厚度来显现,油墨越厚,其膨胀时间延后,转印开始时间变迟,即下水位置拉长,可转印范围缩短,油墨包覆能力变弱,易产生针孔不良;1.ThefilmINKcanbedividedinto1C,2C,3C,4C(CmeansColor).TheAppearancescanbedistinguishedfromINKthickness.TheINKisthickorTheexpansiontimeislongorThestartingtimeoftransferwillbelate.Atthesametime,thepositionofenteringwaterwillbeprolongedandthetransferringrangwillbesmalltheabilityofINKwrappingwillbeweakened,soittakeshapepineholdeasily.2.胶膜转印的适合水温通常为30,水中PVA平均浓度应小于0.2%;Thesuitablewatertemperatureoffilmtransferringisusually30℃,PVAaveragedensityinwateris0.2%;条件Condition膨胀开始时间Thestartingtimeofdiffusion转印开始时间Thestartingtimeoftransfer可转印范围Transferablerangle膨胀率Diffusionrate包覆力Wrapabilily水温升高Watertempinctease较早Ealier较早Ealier缩短smaller增加increased不变SamePVA升高PVAinctease较慢Slower稍慢Caer增长Longer稍减decreased改善better水汽Vapor水转印基本知识原材料的认识LearningMaterial条件膨胀开始时间转印开始时间可转印范围膨胀率包覆力水温升水转印基本知识胶膜所适应的温、湿度Applicationtemperatureandhumidity
