had an average size of 21 4 mm and an average thickness of 4 6 mm according to a test screening it is also possible to implement the above described processes for the production of fibre pulp by using a screen which performs the screening at substantially the same consistency as that of the beating in this case the energy consumption will be lower because the amount of energy taken for the adjustment of the consistency will be saved in the following the invention will be described in more detail by means of examples the test results presented in the examples have been obtained by using test methods listed below during the manufacture of coated printing paper according to the invention calender tests were made with an optiload u00ae calender the nip pressure was 500 kn m a 6 roll calender was used for sample 1 an 8 roll calender for samples 2 to 4 the temperature of the calender was adjusted so that it was 110 u00b0 c during the calendering of the sample 2 125 u00b0 c during the calendering of sample 3 and 140 u00b0 c during the calendering of sample 3 the properties measured of the samples are given in table 1 a comparison was made between the properties of the coated printing paper according to the invention and coated printing papers of prior art the grammages of the samples to be compared in the same table are substantially the same the properties are presented in tables 2 to 4 in the following one fibre pulp grade will be presented of which it is possible to make printing paper according to the invention of the fibre pulp grade whose properties are shown in table.
