大(da)(da)家(jia)在我(wo)們(men)(men)日常生(sheng)活,辦事必(bi)須注(zhu)重方法和方法,由于有一(yi)些(xie)小方法,小竅門可以(yi)使我(wo)們(men)(men)的(de)(de)事兒做下(xia)(xia)去(qu)更輕(qing)輕(qing)松(song)松(song),不(bu)干(gan)膠標簽(qian)(qian)(qian)生(sheng)產(chan)中也是這(zhe)般。如果我(wo)們(men)(men)了解(jie)一(yi)些(xie)小技(ji)巧,對大(da)(da)家(jia)不(bu)干(gan)膠的(de)(de)生(sheng)產(chan)和包(bao)裝印刷(shua)(shua)都(dou)具有非(fei)常大(da)(da)的(de)(de)協助功效。不(bu)干(gan)膠標簽(qian)(qian)(qian)印刷(shua)(shua),是用(yong)選定(ding)的(de)(de)方法印刷(shua)(shua)標簽(qian)(qian)(qian)并(bing)在其背(bei)面涂以(yi)薄層不(bu)干(gan)膠,制(zhi)成(cheng)具有自(zi)粘性(xing)不(bu)干(gan)膠材(cai)料;最用(yong)印刷(shua)(shua)設備,生(sheng)產(chan)制(zhi)成(cheng)不(bu)干(gan)膠標簽(qian)(qian)(qian)。下(xia)(xia)面給大(da)(da)家(jia)介紹一(yi)下(xia)(xia)不(bu)干(gan)膠標簽(qian)(qian)(qian)制(zhi)版(ban)過程的(de)(de)小竅門。
1、縮短曝光時間(jian),解決過渡網點生硬的問題(ti)
鼎(ding)翰科(ke)技小(xiao)(xiao)編曾(ceng)經印刷(shua)過(guo)(guo)一(yi)(yi)種有(you)過(guo)(guo)渡網(wang)效(xiao)(xiao)果(guo)(guo)的(de)(de)(de)(de)藥品標簽,客戶要求過(guo)(guo)渡網(wang)的(de)(de)(de)(de)效(xiao)(xiao)果(guo)(guo)要柔和一(yi)(yi)些,可(ke)是打(da)樣(yang)印刷(shua)出的(de)(de)(de)(de)過(guo)(guo)渡網(wang)點(dian)(dian)比較生(sheng)硬(ying),不能滿足客戶的(de)(de)(de)(de)需(xu)求。鼎(ding)翰科(ke)技小(xiao)(xiao)編觀察后發現,過(guo)(guo)渡網(wang)中的(de)(de)(de)(de)最小(xiao)(xiao)網(wang)點(dian)(dian)在3%左右,基本上是凸(tu)印樹(shu)脂版(ban)(ban)所(suo)能曬(shai)出的(de)(de)(de)(de)最小(xiao)(xiao)網(wang)點(dian)(dian)了。如果(guo)(guo)再將網(wang)點(dian)(dian)縮小(xiao)(xiao)后重新(xin)出膠(jiao)片,曬(shai)版(ban)(ban)后很可(ke)能出現小(xiao)(xiao)網(wang)點(dian)(dian)丟(diu)失的(de)(de)(de)(de)現象,所(suo)以不能通過(guo)(guo)重新(xin)出膠(jiao)片的(de)(de)(de)(de)方法來解(jie)決此(ci)問(wen)題。由(you)于凸(tu)印樹(shu)脂版(ban)(ban)是靠光固(gu)化成像的(de)(de)(de)(de),因此(ci)筆者讓制(zhi)版(ban)(ban)人員縮短曝光時間,使樹(shu)脂版(ban)(ban)上曬(shai)出的(de)(de)(de)(de)網(wang)點(dian)(dian)比正(zheng)常(chang)曝光時間所(suo)曬(shai)出的(de)(de)(de)(de)網(wang)點(dian)(dian)小(xiao)(xiao)一(yi)(yi)些,再次打(da)樣(yang)后,過(guo)(guo)渡網(wang)效(xiao)(xiao)果(guo)(guo)變得(de)柔和,客戶對(dui)其(qi)很滿意,我們也成功完成了這一(yi)(yi)訂單。
2、背曝光解決大(da)面積過渡網(wang)掉(diao)點問題
熟悉柔(rou)版(ban)(ban)制(zhi)(zhi)(zhi)版(ban)(ban)工(gong)藝的(de)(de)(de)(de)人都知(zhi)道,柔(rou)性版(ban)(ban)制(zhi)(zhi)(zhi)版(ban)(ban)過(guo)(guo)程(cheng)中有(you)背(bei)曝(pu)(pu)(pu)光(guang)(guang)(guang)(guang)工(gong)序,其(qi)目(mu)的(de)(de)(de)(de)就是為了讓圖(tu)文與(yu)版(ban)(ban)基結(jie)合得更(geng)加牢固。但可能(neng)(neng)許多人不知(zhi)道這種背(bei)曝(pu)(pu)(pu)光(guang)(guang)(guang)(guang)工(gong)藝同樣(yang)可以(yi)應用(yong)于凸印樹脂(zhi)版(ban)(ban)的(de)(de)(de)(de)制(zhi)(zhi)(zhi)版(ban)(ban)過(guo)(guo)程(cheng)。在(zai)日常生(sheng)產中,我們經常會遇到有(you)大(da)面(mian)(mian)積平(ping)網(wang)或大(da)面(mian)(mian)積過(guo)(guo)渡網(wang)的(de)(de)(de)(de)活(huo)(huo)件,在(zai)曬版(ban)(ban)過(guo)(guo)程(cheng)中經常由于曝(pu)(pu)(pu)光(guang)(guang)(guang)(guang)時(shi)間(jian)掌握不好而出(chu)現小網(wang)點丟失(shi)的(de)(de)(de)(de)問題,尤其(qi)是制(zhi)(zhi)(zhi)作有(you)大(da)面(mian)(mian)積過(guo)(guo)渡網(wang)的(de)(de)(de)(de)印版(ban)(ban),對曝(pu)(pu)(pu)光(guang)(guang)(guang)(guang)時(shi)間(jian)的(de)(de)(de)(de)要(yao)求(qiu)更(geng)苛刻:時(shi)間(jian)太長可能(neng)(neng)糊(hu)版(ban)(ban),時(shi)間(jian)太短(duan)則可能(neng)(neng)掉網(wang)點。此時(shi),可以(yi)在(zai)制(zhi)(zhi)(zhi)版(ban)(ban)時(shi)采(cai)用(yong)背(bei)曝(pu)(pu)(pu)光(guang)(guang)(guang)(guang)的(de)(de)(de)(de)工(gong)藝,即讓樹脂(zhi)版(ban)(ban)的(de)(de)(de)(de)背(bei)面(mian)(mian)接受(shou)曝(pu)(pu)(pu)光(guang)(guang)(guang)(guang),背(bei)曝(pu)(pu)(pu)光(guang)(guang)(guang)(guang)的(de)(de)(de)(de)時(shi)間(jian)要(yao)根據不同的(de)(de)(de)(de)活(huo)(huo)件靈活(huo)(huo)掌握。實踐證實:經背(bei)曝(pu)(pu)(pu)光(guang)(guang)(guang)(guang)處理(li)后的(de)(de)(de)(de)樹脂(zhi)版(ban)(ban)材在(zai)曬大(da)面(mian)(mian)積過(guo)(guo)渡網(wang)點時(shi)就不容易(yi)出(chu)現掉網(wang)點的(de)(de)(de)(de)現象。
