關於印刷廠​紙張的紙張的重量及計算【步殼印刷】

關於印刷廠紙張的紙張的重量及計算【步殼印刷】


紙張的重量可用定量和令重來表示。定量俗稱“克重”,即每平方米紙張的重量,以克表示。克重並不是連續式增加的,常用的紙張定量有52g/m2、60g/m2、70g/m2、80g/m2、100g/m2、105g/m2、120g/m2、128g/m2、150g/m2、157g/m2。

定量不超過250gm2的一般稱為“紙”,超過的則稱為“紙板”。低定量的紙板也常稱為卡紙。

令重表示1令紙(500張全張紙)的總重量,可通過紙張的面積和定量來計算:

令重(kg/m2)=單張紙的面積(m2)x500×定量(g/m2)÷1000例如,787mm×1092m規格的60gm2膠印書刊紙的令重為令重=0.787×1.092×500×60÷1000=25.782(kg)。
