印刷紙張令重、基重對照表

說明:

  • GSM – 基重(basis weight):為一張1平方公尺大小紙張的重量(在口語上或可簡稱為gram),相同基重的紙出廠尺寸愈大,令重愈大。
  • P.,Lb. – 令重(ream wright):為某出廠尺寸大小的紙500張的總重量或簡稱為磅(P.,Lb.),這和印前打字中的P.(點, Point, 72 points = 1 inch)是不一樣的。
  • pt. – 而國外對紙張需求的規格描述還有一個方式,就是紙厚(caliper),而它的單位是point(s),一個point代表千分之一英吋,8 points就代表一張紙的厚度約是0.198mm,大概是一般175GSM的紙張厚度。
  • 常用紙張尺寸為31″ x 43″(46版, B size)及25″ x 35″(菊版, A size)兩種。
