Dear kirsir,

unfortunaltey this problem is coming from the printer. The CM update is making the problem less worse, but even with the update, some colors will be printed with these dots.
You can try the follwoing.
Change the media weight on the printer directly to medium and print with or without the RIP with the printer default setting. So, do not use User Type 1. In this case the dots will be less.
This is the only thing you can try. We are still working on a solution.
