marks on pressing

Once you have cut a master laquer, you have metal stampers created and have records pressed from them. Discuss manufacturing here. (Record Matrix Electroforming- Plating, Vinyl Record Pressing.)

marks on pressing

Hi all we use a custom press for pressing a small amount of disks. We have an issue that we can not get rid of. If you look at the photo you see some marks on the pressing which are creating bad visual and acoustical result. It only happens when disk is well stabilised (cooled). It looks something like a movement prior seperation.
Does this ring a bell to anyone?

Thanks in advance.
