紙張的重量以定量及令重表示,通常以定量表示定量又稱克量,是單位面積紙張的重量,單位g/m2,即每平方米的克重。如60g/m3的意思是每平方米紙的重量是60克。

印刷紙張的重量

紙張的重量以定量及令重表示,通常以定量表示定量又稱克量,是單位面積紙張的重量,單位g/m2,即每平方米的克重。如60g/m3的意思是每平方米紙的重量是60克。

通常250g/m2以下稱為紙250g/m2以上成為紙板。在印刷行業,表示紙張重量的單位還有令重,單位是kg(公斤)。

1令重紙為500張全開紙。

根據紙張的定量和幅面尺寸,可用以下公式進行令重與定量的換算

令重(kg)=紙張的面積(m2)×500定量(g/m2)÷1000

紙張發展速度很快,目前世界上已能生產出600多種不同性質的紙和紙板,我國已細化了500多種規格的紙和紙板,以適應不同的印刷要求
