PURPOSE:To provide the titled apparatus ideal for a sheet-fed press accurately controllable with a high frequency of lateral turning by correcting effect on an inking mechanism attributed to the number, lateral turn degree and the frequency of lateral turning in lateral turn rollers. CONSTITUTION:A pattern area rate Sn of a plate material is memorized into a memory 9 while a constant for weighted mean attributed to the number of ink keys and a lateral turn roller 8 is memorized into a memory 10. According to pattern area rates S1, S2...Sn fed sequentially to a buffer 12, based on the relationship of In=F<-1>(Sn) (F<-1> is inverse function of f2, f3 and f4. In ink supply necessary for No.n zone, f2 probability due to lateral turn degree of ink; f3 probability due to frequency of lateral turning, and f4 function determining the amount of ink), a weighted mean computation is done with a computing section 11, results I1, I2...In applied to a conversion circuit 13 to determine Gn=f1(In) and the value of ink key opening Gn is memorized into a memory 14 to control an ink presetting system. |
