This used to happen a lot on my platens, which is why I loved the V36 and the Kelly! However, to the problem at hand: two things I would try would be to (carefully) thin the ink with reduction varnish or tack reducer, and also running thick vertical borders outside the image area, to relieve some of the tendency of the rollers to mash down over the edge of the image.
This assumes that your rollers are set correctly and are fairly new, and that the temperature of the ink and rollers is within reason.
All else failing, then you might try either thin tissue or Scotch tape as packing under the image area. You can duplicate the image by using a proof sheet as a guide for cutting the packing to fit where you need more impression.
(This used to drive me nuts on a 12×18 Kluge. I had a client who carved in wood, and he would bring in a chunk of fairly flat cedar with an image on it and want me to pull good quality images—as you can imagine, the make-ready was a major expense, but it could be done.)
i ASSUME YOU HAVE TRY EVERYTHING i’VE READ, ONE OTHER THING IS YOU CAN CHECK THE POLYMER PLATE IT SELF FOR BAD MANUFACTURING THE PRODUCT. THIS PROCESS HAS BEEN WORKING BUT NOT 100 %. ON YOUR HEATED TIMER ( UV ) LAMP LEAVE THE PLATE IN LONGER AND GO THRU THE PROCESS MORE INTENSE
