    What is the solution to a problem?
    Today I had paper for printing. It was golden in color and the color level was 100%.
    There was a watermark in the middle of the paper, but unfortunately the watermark did not appear after it was printed on the paper because the color was 100%.
    What do you think about how to solve this problem if it occurs again?

    I don't know what you exactly mean. Was the paper gold in colour or you've printed it in gold?

    I printed it in gold, but the watermark was erased and does not appear on the paper

    That's because you are using metallic ink it is not allowing water mark to be visible

    This paper was printed before and the watermark was visible. I do not know why it did not appear this time

    No. It's NOT watermark. Watermark is in the paper.

    The watermark is not on the paper and I don't know why
    Although it is present on the zinc plate indicated in the picture between two red arrows

    a true watermark is in the paper as it comes from the mill. If you print over the watermark it just may disappear under the ink depending on the inks transparency. Metallic inks are the most opaque of all offset inks. Im not at all surprised that your water mark was lost under just about any ink with any degree of opacity.
