Water Roller Sizes for the 3M Machine

[ali 120]

I have a machine modified to the 3M system; it uses one Molleton roller to pick up water and another—a rubber roller—that contacts the printing cylinder (or plate cylinder). What is the correct size for this rubber roller: 52 or 55?

I don’t remember the final diameter required for contact (is it 55mm?) you would then subtract 3mm, as the 3M sleeve is 1.5mm thick.
