Paper making – the nitty gritty: Calendering

Every now and then we dive deeper into the details of paper making by highlighting a certain part of the process. This time we are focusing on calendering, which is one of the crucial steps in achieving Multicopy’s excellent print results.

Calendering is the process by which the paper’s surface is altered to achieve a smooth finish – improving its printability properties. If not calendered, many printing papers simply wouldn’t measure up to the required printing quality. Our uncoated grades, like the office papers in the Multicopy family, manufactured at Nymölla Mill, are treated through a soft nip calendering process.

The soft calendering machine uses heat, pressure and friction to produce the required result as the paper web is pressed through two “rolling” nips. These soft rolls have an elastic cover that form a nip, replicating the surface of the tempered roll with a hard surface – that is where the smoothness is created. 

– WHY, WHAT AND HOW?
