    I want the correct measurements for the gto 52 machine
    The distance between the printing cylinder holder and the blanket cylinder holder
    And the distance between the blanket cylinder holder and the lower impression cylinder holder
    Is it normal for there to be no space between the printing cylinder holder and the blanket cylinder holder? When I put some ink on the printing cylinder holder with the blanket cylinder holder and the machine is running in printing mode, the ink appears on the printing cylinder holder. Is this true?

    As it is in the picture

    What do you mean by holder? A bearer? If so - yes, machine is printing bearer to bearer.

    Yes, plate to blanket will be bearer to bearer, and impression to blanket will have a .35mm gap when set at “0”, on impression.

    I mean between the two holders that have arrows on them
    Is it normal for them to be adjacent to each other during normal printing?

    What is the distance between the printing cylinder holder and the plankette cylinder holder when the two are placed on each other?

    When the holders are set to size 0.10 and when the printing is running, the holders are not adjacent to each other. Why?
    Please note that you informed me that it is normal for them to be adjacent to each other when printed

    What do you mean by set to size 0.10?
    Are you packing/plate thickness correct?

    I mean, when the printing cylinder holder is adjusted with the blanket cylinder holder, the distance between them is 10 out of a hundred. Is this correct?
    If it were true during normal printing, the printing cylinder holder and the blanket cylinder would not be adjacent to each other.

    Is there a video or diagram for the correct adjustment?

    At no time should you ever be able to get any thickness of feeler gauge between plate and blanket bearers.

    Why
    There must be sizes between the printing cylinder holder and the blanket cylinder holder

    Only at the beginning of the adjustment procedure. Once full procedure is completed, the bearers are together under heavy spring load.

    I have seen that some people say that the distance between the impression cylinder holder and the blanket cylinder holder should be 0.10 of a hundred when the two holders are facing each other.

    As I stated previously, when unit is on impression, and the adjustment indicator arrow on side frame is set at “0”, there should be a .35mm gap between blanket and impression bearer rings. No gap between plate and blanket. I’m assuming you are calling the bearer rings “holders”. Otherwise, I’m not sure what you speak of.

    We speak of the same thing, your term “holder” are what we call bearer rings. If you are able to get a feeler gauge between the bearer rings, there is something wrong mechanically. Best case, bearer pressures require resetting. You may have damaged bearing bolts or bent cylinder journals. You should seek professional help.

    Are the bearing rings firmly in contact with each other when printed?
