the minimum acceptable speed v min is 3 000 sheets hour and the maximum acceptable speed is v max 9 000 sheets hour the actual speed v lst is 6 000 sheets hour the target speed v soll is 12 000 sheets hour thus the control computer 15 may immediately accelerate the printing press 1 to v 9 000 sheets hour and then more slowly along the tolerance limit t 30 to v 12 000 sheets hour when the target speed v soll 12 000 sheets hour is reached the inking unit 14 continues to be heated up by the temperature control circuit 16 to the optimum temperature t of 35 for a speed v 12 000 sheets hour fig6 illustrates the progression of the speed v lst as a function of the time t when the press 1 is accelerated from 6 000 to 12 000 sheets hour the chart shows that initially the printing press 1 accelerates very quickly to 9 000 sheets hour then it accelerates more slowly along the tolerance limit at a second acceleration to a speed of 12 000 sheets hour fig7 illustrates a second example in which the printing press 1 is accelerated from a printing speed v lst 6 000 sheets hour to a speed v soll 8 000 sheets hour again the target coloration is predetermined at 30 temperature t lst is 25 at the speed v lst and the temperature tolerance limit is 5 this means that the lower limit t minus is.
