Hi, Facing doubling issue in SM102 1986, Its a 2+3 press, when printing straight, the first two units double and this can be seen in attached pictures and also on blanket cylinder of the 3rd unit. Now the strange part is that, 2 sheets show double around 1 mm lower to the printing and 2 above the original print. If we do perfecting then this doubling position changes after every sheet. Showing on the perfected side. Any leads in this regard would be much appreciated.
