高質量的印刷薄紙,這些外部管理經驗一定要看!

眾所周知,厚紙印刷和薄紙印刷有著很大差異。因而,在實踐操作時,應依據需求選擇適宜的紙張類型。濟南精裝書制作公司在這里提示大家,薄紙是指定量在60g/m2以下的紙張,比方60g/m2輕型紙、55g/m2書寫紙等。我們將薄紙放在強光處察看,會看到很多細小的孔隙,這是由紙張的工藝特性決議的。薄紙定量小,紙張的強度和韌度不夠,易變形翹邊,這些特性使得薄紙在印刷過程中特別容易形成輸紙毛病,在高速運轉狀況下,容易因紙角撞擊前規或遞紙牙而形成重影、出褶等印刷毛病。
As we all know, there are great differences between thick paper printing and thin paper printing. Therefore, in practice, the paper type should be selected according to the demand. Jinan Hardcover Book Manufacturing Company here reminds you that thin paper refers to paper with a ration of less than 60g/m2, such as 60g/m2 light paper, 55g/m2 writing paper, etc. When we put the thin paper in the bright light, we can see many tiny holes, which are determined by the technological characteristics of the paper. Thin paper has small quantity, insufficient strength and toughness, and easy to deform and warp edges. These characteristics make thin paper easy to form paper feeding defects in the printing process. Under high-speed running conditions, it is easy to form duplication and folding defects due to the impact of paper corner on the front or the delivery teeth.
首先,要控制影響薄紙印刷的環境溫濕度。印刷薄紙時,更好現裁現用,這樣可更大限度地減少紙張與空氣的接觸時間。假如所裁紙張(包括半廢品)沒有立刻運用,應當用保鮮膜或拉伸膜把紙張纏繞起來,避免其因接觸空氣而變形。為了保證紙張內部含水量的合理(6%左右),還應留意紙張的堆放位置,不宜靠墻、靠窗、靠水龍頭、靠暖氣(冬天),更不可露天放置,以免過于枯燥而毀壞紙張含水量的合理,形成紙張翹曲不對等結果。
First of all, we should control the environmental temperature and humidity that affect thin paper printing. When printing thin paper, it is better to cut it now, so as to minimize the contact time between paper and air. If the cut paper (including semi-waste) is not used immediately, the paper should be wrapped up with fresh-keeping film or stretching film to avoid deformation due to air contact. In order to ensure that the moisture content of paper is reasonable (about 6%), we should also pay attention to the stacking position of paper. It is not suitable to place paper by wall, window, tap, heating (winter), and not open-air, so as to avoid being too dry and destroying the rationality of moisture content of paper, resulting in unequal warping of paper.
其次是在控制薄紙印刷影響要素的根底上,針對性地對紙張停止合理調控,可采取以下辦法處理。
Secondly, on the basis of controlling the influencing factors of thin paper printing, we can take the following measures to control the paper rationally.
(1)除濕法:應用空調的除濕功用去除室內空氣中多余的水分,就能夠有效到達除濕的目的。印刷車間的規范環境為溫度20℃左右、相對濕度55%~65%RH。
(1) Dehumidification: The purpose of dehumidification can be effectively achieved by using the dehumidification function of air conditioning to remove excess moisture in indoor air. The standard environment of printing workshop is about 20 C and 55%-65% RH.

(2)砸頁法:假如紙張印刷后呈現卷曲現象,可用砸頁法加以處理,將所切印張翻身,用手工“砸紙”的辦法把卷曲的印張敲砸出許多折線,應用折線與折線之間產生的支撐力,強行改動彎曲的印張,使之相對平整。

(2) Page smashing method: If the paper is curled after printing, it can be dealt with by page smashing method, turning all the printed sheets over, using manual "paper smashing" method to smash the curled sheets out of many folded lines, applying the support force between folded lines and folded lines, forcibly changing the bended sheets to make them relatively flat.
(3)晾紙法:晾紙法是應用晾紙機將裁切后的紙張或者沒有裁切的紙張通風吹晾,使紙張內部的濕度和空氣濕度堅持相對均衡,使紙張的含水量契合印刷請求并堅持穩定,保證其在印刷和印后加工中不易變形。這樣既可進步印刷質量,也能給印后加工減少很多費事。
(3) Paper-drying method: The paper-drying method is to use the air-drying machine to air the cut paper or uncut paper, so that the humidity and air humidity inside the paper can be kept relatively balanced, so that the moisture content of the paper can meet the printing requirements and maintain stability, and ensure that it is not easy to deform in printing and post-printing processing. This can not only improve the quality of printing, but also reduce a lot of trouble for post-press processing.
輸紙臺板的合理調理是保證輸紙精確的前提,必需設定好輸紙臺板各個部件的位置。
Reasonable conditioning of the feeding board is the precondition to ensure the accuracy of the feeding. It is necessary to set the position of each component of the feeding board.
(1)過橋輪一定要調理得稍松一點,起落分歧,以避免紙張變形。
(1) The bridge wheels must be adjusted a little loosely to avoid paper deformation.
(2)關于有輸紙線帶的印刷機,輸紙線帶的張力一定要分歧,線上的壓力分歧并稍輕一些,否則易形成紙張變形嚴重、傾斜,惹起嚴重的輸紙毛病。
(2) For a printing machine with paper feeding tape, the tension of the paper feeding tape must be different, and the pressure on the line must be different and slightly lighter, otherwise the paper will easily become seriously deformed and inclined, causing serious paper feeding problems.
(3)關于帶有真空輸紙線帶的印刷機,調整時特別要留意。首先,真空輸紙線帶的賭氣壓要比自動設定的數值低一些,能到達設定的三分之一即可,必要狀況下能夠為零。其次,前規制動輪的吸風量也要相應減小,減小到原先自動設定的一半左右即可,否則容易使紙張中間起凸,光電檢測到紙張晚到或傾斜,印品要么出折,要么重影。
(3) With regard to the printing press with vacuum feeding tape, special attention should be paid to the adjustment. First of all, the betting pressure of the vacuum paper feeding line is lower than that of the automatic setting value, which can reach one third of the set value, and can be zero if necessary. Secondly, the suction capacity of the front brake wheel should be reduced to about half of the original automatic setting. Otherwise, it is easy to make the paper bulge in the middle. Photoelectricity detects that the paper arrives late or tilts. Printing products are either folded or duplicated.
