Phil,
He cannot, that's the point. They use water based dextrines and
machine weaving the paper are the size of a small city block. The
pressure on the paper tape 20+ feet wode and miles long keeps it
straight until it makes its routs thru different drums. Temp and
humidity control is the key and such papers being for special purpose
are not cheap either. The only dextrine based paper that works is
from pulsar at $1 a sheet, then I tried couple other special purpose
papers for transfer of T-shirt images-expensive. the cheapest paper
for that worked for me in H200 is that Staples paper we talked
already about. I mean, it costs 50c for the lucky ones in US.
I've been baking bread since 1989 and it is after 13 years when I
started getting a grip on baking. What can be simpler: water, flower
and yeast. There are million books on the subject and 99% are not
worth paper they are printed on. I'll stick to H200 with Staples for
now (0.032"_.
