    I have a Komori Sprint 226 P , 2 colour machine
    Currently im facing a problem with misregistration on the press
    The image of Unit 1 is increasing from the tail edge of the paper (60 gsm), I can show the pics if needed.
    I have read, to adjust you need to
    1. Increase the plate height by adding the packing
    2 Decrease blanket height by the amount of packing change.

    Do i have to do it simultaneously this thing or one by one, can you please through some light on it
    I would be really greatfull

    Thanks with regards

    Yes, whatever you add under the plate you have to subtract from the blanket start with 0.004" or 4 thousandths" good luck.

    No, I believe you're describing fan-out. This would be more from the substrate being deformed at transfer of sheet, whether at infeed or anywhere throughout the press. Given it's a perfector, that would be a main concern.
