machine finish
Quick Summary
Machine finish, often abbreviated as M.F., refers to a moderately smooth surface applied to book and cover papers. This finish is achieved by passing the paper through the calender rolls of a paper machine.1
Calendering is a crucial part of paper finishing. It involves smoothing and compressing paper by running it through pairs of heated rolls. These rolls, collectively known as calenders, can exert significant pressure. For coated papers, calendering is essential for creating a smooth, glossy surface. This process is one of several finishing operations that transform paper rolls into a usable product for consumers.23
