    Dear all,
    We are running XL106+l full UV
    When printing UV coating you can see tahhat curing and rub (scratch) resistance are ok. But we feel that the UV coating is sticky for example, if you rub two printed faces together they will not slipping.
    Note: the first sheet at the top of the pile, is OK, but if you took a sheet from the middle it's not OK.
    I cleaned and checked the (end of press) lamps, the cooled air hoses and the exhaust air, all are OK.
    Any help would be appreciated.
    Thanks in advance.
