Strange Artifacts on First layer

Hi guys,

I have these strange artifacts during the First layer.
I clean the bed with isoprophilic alcool a lot and warm the bed at 65 degrees for 10-15 mins before launching the print.

These errors come random in my First layer,not at the same areas.

What can i do?

Best regards and thanks in advance
