1.機器(qi)壓印關聯部件(jian)不良引起的質量故(gu)障
當印版輥筒軸頭、壓(ya)(ya)(ya)印輥軸頭、傳動軸、齒輪(lun)以及與壓(ya)(ya)(ya)印相關(guan)聯的重要部(bu)件出現(xian)磨(mo)損(sun)、松(song)動時，在壓(ya)(ya)(ya)印過程中印版輥或壓(ya)(ya)(ya)印輥會因此產生跳動或滑動現(xian)象，由(you)于壓(ya)(ya)(ya)力不穩定，致使印版面與紙板接觸不正常，造成紙板印刷表面出現(xian)糊版或局部(bu)圖(tu)文(wen)印跡不清的問(wen)題。通過認真仔(zi)細的觀(guan)察和分析，查明(ming)故障的確切(qie)部(bu)位(wei)，采取相應的措施進行處理(li)，對磨(mo)損(sun)、松(song)動的部(bu)件予以修復，消(xiao)除故障現(xian)象。
2.著墨輥(gun)不良引起的質量故障
當著(zhu)墨輥(gun)(gun)(gun)軸頭松動，著(zhu)墨輥(gun)(gun)(gun)輥(gun)(gun)(gun)體出現彎(wan)曲、變形或表(biao)面破損(sun)時，也(ye)會引起(qi)版面臟(zang)、糊(hu)版或局部圖文不清晰。應(ying)查明原因，采取相應(ying)的措(cuo)施(shi)予(yu)以處理，使著(zhu)墨輥(gun)(gun)(gun)與(yu)印版之(zhi)間保持(chi)均勻而又(you)合適(shi)的接觸條件，對(dui)損(sun)壞的著(zhu)墨輥(gun)(gun)(gun)予(yu)以更(geng)換，才能消除故障(zhang)現象(xiang)。
3.壓力輥調整不當引(yin)起的(de)質量(liang)故障
若(ruo)壓力(li)輥的位置過高(gao)或(huo)過低，以(yi)致與(yu)瓦(wa)楞(leng)紙(zhi)板接觸過緊或(huo)過松，也(ye)會出現臟(zang)版、糊版或(huo)局部圖文印跡不清情況，應調整壓力(li)輥至合適(shi)的位置，使壓力(li)輥和輥筒之(zhi)間(jian)的間(jian)隙與(yu)紙(zhi)板的厚度相適(shi)應，以(yi)確保印刷版面的部位，避免該故障現象的產生。
4.色序不當(dang)引起(qi)的質量(liang)故障(zhang)
如果將版(ban)面(mian)較滿的圖(tu)文排列在第(di)(di)一色(se)組(zu)(zu)印刷(shua)，當(dang)瓦楞(leng)紙(zhi)(zhi)板進入下(xia)一色(se)組(zu)(zu)機構(gou)印刷(shua)的過程中，由于紙(zhi)(zhi)板第(di)(di)一色(se)組(zu)(zu)的印刷(shua)圖(tu)文的著墨(mo)量(liang)大(da)、干燥(zao)速度(du)慢，極容易使印跡(ji)轉移造(zao)成版(ban)面(mian)起臟(zang)(zang)。為(wei)防(fang)止這一弊病的產生，宜將面(mian)積小的版(ban)面(mian)排列在第(di)(di)一色(se)組(zu)(zu)印刷(shua)，將面(mian)積大(da)的版(ban)面(mian)排列在后續色(se)組(zu)(zu)印刷(shua)，可避免印跡(ji)轉移造(zao)成臟(zang)(zang)版(ban)現象。
5.印版厚度不(bu)均勻(yun)引起的質(zhi)量故障(zhang)
當橡皮(pi)版(ban)(ban)(ban)(ban)(ban)(ban)(ban)材(cai)厚(hou)度不(bu)(bu)均(jun)勻時，印(yin)版(ban)(ban)(ban)(ban)(ban)(ban)(ban)版(ban)(ban)(ban)(ban)(ban)(ban)(ban)面就會出現(xian)高低差(cha)(cha)。版(ban)(ban)(ban)(ban)(ban)(ban)(ban)面高的(de)地方就容易糊版(ban)(ban)(ban)(ban)(ban)(ban)(ban)，版(ban)(ban)(ban)(ban)(ban)(ban)(ban)面低的(de)地方就容易出現(xian)著墨不(bu)(bu)全，造成印(yin)跡不(bu)(bu)清晰，為避免這一不(bu)(bu)良(liang)情況的(de)發(fa)生(sheng)，可(ke)(ke)采用零星制(zhi)版(ban)(ban)(ban)(ban)(ban)(ban)(ban)的(de)方式，將版(ban)(ban)(ban)(ban)(ban)(ban)(ban)材(cai)制(zhi)成若(ruo)干小塊(kuai)的(de)（指那種為節(jie)約橡皮(pi)版(ban)(ban)(ban)(ban)(ban)(ban)(ban)材(cai)而不(bu)(bu)制(zhi)版(ban)(ban)(ban)(ban)(ban)(ban)(ban)芯的(de)制(zhi)版(ban)(ban)(ban)(ban)(ban)(ban)(ban)工(gong)藝(yi)），應采用同一塊(kuai)版(ban)(ban)(ban)(ban)(ban)(ban)(ban)材(cai)分別進(jin)行制(zhi)作，這樣它(ta)的(de)厚(hou)度差(cha)(cha)異(yi)比較小。如(ru)果已經制(zhi)好的(de)橡皮(pi)版(ban)(ban)(ban)(ban)(ban)(ban)(ban)，存在厚(hou)薄差(cha)(cha)時，可(ke)(ke)在局部偏薄的(de)印(yin)版(ban)(ban)(ban)(ban)(ban)(ban)(ban)背面多粘膠布層彌補(bu)，使整個印(yin)版(ban)(ban)(ban)(ban)(ban)(ban)(ban)保(bao)持基本一致(zhi)的(de)厚(hou)度，確保(bao)印(yin)刷壓力和(he)版(ban)(ban)(ban)(ban)(ban)(ban)(ban)面著墨的(de)均(jun)勻。
6.瓦楞(leng)紙板厚(hou)度(du)不均勻(yun)引起的質量(liang)故(gu)障
如(ru)果成(cheng)形的(de)(de)瓦(wa)楞紙板表面(mian)(mian)有人為(wei)破(po)壞的(de)(de)凹陷痕跡(ji)時(shi)，凹陷部(bu)位(wei)的(de)(de)紙面(mian)(mian)也會(hui)出現印(yin)跡(ji)不(bu)清(qing)晰的(de)(de)質量缺陷，對此(ci)如(ru)果采(cai)用全面(mian)(mian)加大印(yin)刷(shua)壓力彌(mi)補，容(rong)易使文字、線條版面(mian)(mian)出現起糊(hu)(hu)的(de)(de)質量問題(ti)。為(wei)了避免(mian)版面(mian)(mian)起糊(hu)(hu)，瓦(wa)楞紙板在堆放(fang)、搬(ban)運過程中，應(ying)注(zhu)意輕搬(ban)、輕放(fang)、輕壓（要控制好堆放(fang)高度），切忌(ji)采(cai)用扔、砸、壓等不(bu)良生產習慣進行搬(ban)運。
