Interesting speculation but I doubt the vacuum is such, in any of
these machines, to be able to pull a polyester-backed plate into the
vacuum line. That would sort of be a major engineering flaw. I process
both steel-backed and polyester-backed plates in my machine and I
can't imagine this to be the case. While polyester-backed plates are
certainly flexible (and a bit unnerving to those accustomed to
steel-backs), they are not flexible enough to be drawn down into that
thinly etched vacuum line, unless there is something wildly out of
wack with Jessica's vacuum pump!
