Fogra finger rub off test device FIWI
The Fogra finger rub off test device serves for assessing the rub resistance of the ink layer. With this device the dirtying of products by hands or fingers can be simulated. The influence of grease and sweat is a key factor. The devices available on the market for the assessment of abrasion and rub resistance are not able to adequately take these specific factors into account.
The Fogra WIKAT enables the manufacturer to check in advance, whether printing ink is transfered to adjacent sheets during the converting step by rub-off and/or carbonating. The test can be easily performed and yields a result at once and without additional cost. With the result of this test in mind it is possible to take appropriate measures to avoid costly complaints.
The Fogra FI Folding Device is a device for the production of sample folds, particularly on paper. With the help of a subsequent tensile strength test on a tensile testing apparatus, the residual strength of the specifically folded sample can be determined. The residual tensile strength characterizes the strength of the fold, for example following the heat treatment of paper (drying in web offset).
