Hi.

We run on our Heidelberg SM 102-8 colour made 2012 with semi autoplate change.

I noticed does not push plate to autoplate clamp cca.3 -4 mm so i must myself push and hold meantime when autoplate clamp close on all unit by hand

Promlem is if we run big size 1020 x 720 and we cant make good register.

Its like spring have poor pressure to plate.

Somebody know where is problem

Thanks
