    Hi
    Please let me know hat can be reason for this print defect.
    Two different coated paperboard, but the same print job with over print varnish., one is good and another one is poor with some spots on final image.
    Those spots magnified under microscope and the same thing attached herewith.
    Unprinted board of poor sample exhibits slow ink set off while compared to good sample.
    Please refer the attachments.
