    在東(dong)莞(guan)釘箱機的(de)生(sheng)產(chan)過程(cheng)中經常出(chu)現的(de)兩(liang)(liang)個(ge)問(wen)題(ti)。印(yin)(yin)刷圖(tu)案或文字(zi)周圍出(chu)現重(zhong)影(ying)(ying)，是(shi)因為網紋輥(gun)(gun)與(yu)印(yin)(yin)版(ban)(ban)(ban)的(de)壓(ya)(ya)(ya)(ya)力(li)(li)過大(da)引起的(de)；印(yin)(yin)字(zi)前部邊緣出(chu)現重(zhong)影(ying)(ying)，則是(shi)因為印(yin)(yin)刷滾筒與(yu)壓(ya)(ya)(ya)(ya)印(yin)(yin)輥(gun)(gun)之(zhi)間(jian)的(de)壓(ya)(ya)(ya)(ya)力(li)(li)過大(da)引起；大(da)面積印(yin)(yin)刷透底、漏白又是(shi)由(you)于印(yin)(yin)刷輥(gun)(gun)與(yu)壓(ya)(ya)(ya)(ya)印(yin)(yin)輥(gun)(gun)壓(ya)(ya)(ya)(ya)力(li)(li)不夠所產(chan)生(sheng)。解決印(yin)(yin)刷重(zhong)影(ying)(ying)問(wen)題(ti)應(ying)當調整(zheng)網紋輥(gun)(gun)和(he)版(ban)(ban)(ban)輥(gun)(gun)之(zhi)間(jian)的(de)間(jian)隙(xi)和(he)壓(ya)(ya)(ya)(ya)力(li)(li)（俗稱上壓(ya)(ya)(ya)(ya)力(li)(li)）。重(zhong)影(ying)(ying)是(shi)因為上壓(ya)(ya)(ya)(ya)力(li)(li)過大(da)，網紋輥(gun)(gun)擠壓(ya)(ya)(ya)(ya)印(yin)(yin)刷版(ban)(ban)(ban)(指柔性版(ban)(ban)(ban))變(bian)形產(chan)生(sheng)，因此(ci)要增(zeng)加(jia)兩(liang)(liang)輥(gun)(gun)的(de)間(jian)隙(xi)，相應(ying)減少壓(ya)(ya)(ya)(ya)力(li)(li)；解決印(yin)(yin)刷漏白問(wen)題(ti)則應(ying)調整(zheng)版(ban)(ban)(ban)輥(gun)(gun)與(yu)壓(ya)(ya)(ya)(ya)印(yin)(yin)輥(gun)(gun)之(zhi)間(jian)的(de)間(jian)隙(xi)和(he)壓(ya)(ya)(ya)(ya)力(li)(li)（俗稱下壓(ya)(ya)(ya)(ya)力(li)(li)）。

東莞釘箱機的優勢
　　第一，東莞釘箱機可以儲存大量紙張，減少換紙和停機次數，提高機器利用率；第二，卷筒紙比單張紙便宜，可降低5%～25%的紙張成本，若是涂覆的紙板或薄膜，用卷材還可獲得更高的經濟效益；第三，紙張裁切長度可無級調整，使用方便，不會產生單張紙印刷前天頭、地光腳邊而造成紙張浪費；第四，可以使浪費四它用單張紙膠印機不能使用的薄紙、薄塑料進行印刷；第五，徹底解決雙張或多張進紙故障；第六，操作人員無需堆紙，降低勞動強度。
　　劣勢
　　第一(yi)(yi)，卷(juan)筒(tong)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)無法事先(xian)挑選(xuan)，所以對卷(juan)筒(tong)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)質(zhi)(zhi)量的要(yao)求(qiu)較高，要(yao)求(qiu)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)卷(juan)沒(mei)有(you)或極少有(you)接(jie)頭，紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)卷(juan)標準（無橢圓(yuan)度(du)(du)(du)、錐度(du)(du)(du)等(deng)缺陷），紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)卷(juan)不(bu)(bu)能(neng)(neng)有(you)皺折，紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)張本身不(bu)(bu)能(neng)(neng)有(you)質(zhi)(zhi)量缺陷（如(ru)小洞、破口、撕裂等(deng)）。第二，卷(juan)筒(tong)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)干濕度(du)(du)(du)不(bu)(bu)像(xiang)單(dan)張紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)那(nei)樣可以晾曬處理，對直接(jie)使用的卷(juan)筒(tong)紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)的干濕度(du)(du)(du)應該有(you)一(yi)(yi)定的要(yao)求(qiu)，并且在紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)卷(juan)存放過程中(zhong)要(yao)注意(yi)環境干濕度(du)(du)(du)對紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)張質(zhi)(zhi)量的影(ying)響。第三，紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)張的平整度(du)(du)(du)在大紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)卷(juan)時最好(hao)，越向卷(juan)芯越差(cha)(cha)，紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)張越厚(hou)這種(zhong)差(cha)(cha)別就越大。較厚(hou)的紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)、接(jie)近紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)芯處的紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)可能(neng)(neng)影(ying)響使用，有(you)可能(neng)(neng)需要(yao)加平紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)裝置(zhi)。因此，太厚(hou)的紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)或紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)板、瓦楞紙(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)(zhi)板不(bu)(bu)宜(yi)使用。
