Rolls suitable for use in web-fed presses are defined as those rolls which, if tested according to the ISO test standard ISO 3783:2006 concerning the determination of resistance to picking – accelerated speed method using the IGT tester (electric model), give a result of less than 30 N/m when measuring in the cross-direction of the paper (CD) and a result of less than 50 N/m when measuring in the machine direction (MD).
Rulle, mida kasutatakse rotatsioonitehnikaga trükipressides, määratletakse kui rulle, mis juhul, kui neid katsetatakse vastavalt ISO katsestandardile ISO 3783:2006 („Paper and board – Determination of resistance to picking – Accelerated speed method using the IGT-type tester (electric model)”), annavad tulemuseks vähem kui 30 N/m mõõdetuna paberi ristsuunas (CD) ja vähem kui 50 N/m mõõdetuna masinasse sisestamise suunas (MD).
