摘　　要：以"红旗渠小盒"烟包产品为例,分析印刷品表面出现"水雾"现象的原因,研究热收缩膜包装密封工艺对印刷品表面形成"水雾"现象的影响。实验结果表明,防水雾光油的涂布厚度、UV固化仪的干燥功率及干燥速率、防水雾光油是否搅拌均匀等密封工艺对"水雾"的形成均有影响。光油层涂布厚度越小,U V固化仪干燥功率越大,干燥速率越小,产品越不容易出现"水雾"。因此,为减少印刷品在热收缩膜包装时出现"水雾"现象,生产前应进行纸张调湿处理,并对产品进行防水雾测试,生产时保证防水雾光油在使用时搅拌均匀,并控制好光油涂布网纹辊克质量、UV固化仪干燥功率及干燥速率,建立各产品的经验数据,以保证产品质量稳定。The causes of the phenomenon of ＂water mist＂ on the surface of printing products were analyzed by taking the ＂Hongqiqu box＂ cigarette products as an example, while the effect of shrink packaging sealing technology on the formation of ＂water mist＂ on the surface of printing products was studied. Experimental results showed that factors of coating thickness, drying degree and stirring of the waterproof varnishing could affect the formation of ＂water mist＂. Its formation is less likely with thinner thickness of waterproof varnishing coating, the greater UV lamp power and the slower drying rate. In order to reduce the ＂water mist＂ phenomenon, the paper should be carried out for conditioning and tested against moisture before the production, the waterproof varnishing should be mixed evenly, while the roller of varnishing coating＇s weight, UV lamp power, and the rate of machine should be controlled in the production to achieve stable quality control.
