縮(suo)孔是(shi)紙盒包(bao)裝(zhuang)uv打印機彩印墨(mo)膜(mo)(mo)(mo)因流(liu)平較差而發生的(de)故(gu)障問(wen)題之四。膠印噴墨(mo)墨(mo)水uv打印機彩印后，濕(shi)墨(mo)膜(mo)(mo)(mo)在流(liu)平時中(zhong)發生回縮(suo)后為(wei)圓(yuan)形，裸露出出被(bei)彩色(se)印刷(shua)物食材(cai)或兩個道墨(mo)層。產生縮(suo)孔的(de)重要病因是(shi)uv打印機彩印的(de)膠印噴墨(mo)墨(mo)水膜(mo)(mo)(mo)橫豎(shu)一些(xie)的(de)外壁力值多(duo)種。

從原理上講：修復機制是改變濕墨膜的流動性、流平性。噴墨墨水的單單從單單從表面拉伸應變除了要低，另外彩色彩色印刷物村料的潤濕性也是好。正因為上面濕墨膜與下文濕墨膜的軟件界面來源于拉伸應變差，在包裝設計彩色彩色印刷后，該制度的單單從單單從表面拉伸應變走低，促使彩色彩色印刷噴墨墨水會自行展布成刪改的墨膜。對于產生的縮孔出現問題，具體情況有哪類面的做法呢，拉著流平劑企(qi)業——天津青田(tian)來來了解下吧(ba)！
