    Some Copy/Paste work from a Heidelberg document below.

    Inking rollers must be adjusted
    to be oil-friendly (or oleophilic). In an inking system with conventional inks,
    rollers of Shore A hardness between 30° and 35° are used. For UV inks,
    rollers with Shore A hardness of 25° and between 40° and 45° are used.
    Dampening rollers should be water-friendly (hydrophilic). For alcohol
    dampening systems, Shore A hardness of between 25° and 30° is suitable.
    In direct dampening systems, hard rubber rollers are used.

    The Shore hardness of a roller determined with a Shore meter designates the resistance against penetration of a needle taking the form of either a conic section (Shore A) or a point (Shore D), pressed with a defied force (1 kp) for a period of three seconds against the rubber surface.
    Soft rollers are measured with Shore A, and hard rollers with Shore D. The
    general hardness tolerances according to DIN/EN are +/– 5° Shore A.

    Hope this helps.
