overnight is too short, paper should be accustomed to lying flat over
multiple changes in humidity and temperature: the longer you keep it
between blotters and under (moderate) weight the better are the chances it
will stay flat when in the "open". Pressing paper is not recommended
because the weight on the paper surface produced by the press will press it
to "death". Try to wet the paper evenly- let paper relax long enough (to
the point is almost starts to dry again)- put between blotters: two on top
two on bottom at least- put plank (or the like) on top of all and weigh
down (I use multiple weights of about 6 kilo's todistribute the weight on
the plank, board or glass evenly- let dry =B1 5 minutes- open the pile and
put fresh blotter on bottom and top (add dry blotters) to prevent print
through of cockling blotter to the original- compose pile again and wait
for at least one week: the more climate cycles you can stand to wait the
better.

#4 Bas..where can I get the
>Japanese dahlia sprayer: super super?

Japanese dahlia sprayers are super and can be optained from a variety of
suppliers, they come in two makes:

Maruhachi industry co
Kuramata Sangyo

in two sizes, 425 cc and one liter.

they are chrome copper containers with a pump system that lets you
pressurise the water (or other not to viscous fluid) inside. On pressing
the lever they give a wonderfull fine mist of water droplets, "atomised"
water so to speak. The smaller the water droplets you spray on paper the
more evenly wet it will become and also -and this may sound like a paradox-
the wetter it becomes with less water. Small drops have a larger surface
together than the same amount of water in bigger drops, and therefor cover
more paper. You could distribute the water with a large hake brush or any
clean soft brush, this will cause the water to soak into the paper quicker.
On ordering of especially the Maruhachi sprayer don't be surprised that the
bottom ring of the container and the pump's knob have a yellow, pink or
light blue colour.

and just ask for dahlia sprayers, strangely enough I don't know an address
in the US of A (that country north of Cuba). In Holland they cost about
Hfl 130,00 about $80.00

happy spraying,

PS print flattener as liquid stuff is something I don't know anything about
and am curious to learn something about them. I presume they are a sort of
wetting agents that stay in the paper to keep it more moist so the are more
supple?? (like saturated alcohols, glycerine??).
