Does this model have the kreene attached to a steel rod that you roll
down? I've found that vacuum is much more secure without the steel
rod. I cut a sheet to fit the vacuum table and leave it at that. Seems
to prevent any vacuum problems.
But I really don't understand how the vacuum could pull down the
kreene stronger in one area of the plate than another. Or how that
would leave "plaid marks" on the plate itself. Especially, I guess, as
there is a film negative between the kreene and the plate.
Next question toward a solution I suspect is what type of film and
plate are you using? Or, are you sure this isn't an exposure or
washout problem? A low water level can cause the brushes to mark the
surface of a plate.
