Pick Test (ISO 3783):
What | Determination of resistance to picking. |
Why | This test is especially important for papers and boards which are to be printed in lithographic offset or letterpress, because the inks used in these techniques traditionally have a high viscosity and high tack values. |
How | An accelerated speed method for determining the surface strength in terms of the pick velocity and pick resistance of coated and uncoated paper and board, and in terms of the delamination resistance of the liner on paperboard, by simulating the behaviour in the printing process. |
Calculation | The results are automatically analysed and shown in the display of the IGT Amsterdam: pick distance in mm, pick velocity and resistance in m/s. |
Note | This test method is explained in W31-leaflet. |
