Need Help Mimaki UCJV300 overspray print

[RAWE Michal]

Hello! I do have a question. I have Mimaki UCJV300 and I am having some troubles with print quality. CMK are overspraying, Y W and clear is just fine and sharp. I did feed and drop position, temperature and humidity is ok. Test print is 100% ok. Head is set to low position. It happens with both bi/uni direction print, all resolutions.
Do you have any ideas what might be wrong? pictures attached below.

Thanks!

Mick
