- Dear Folks,
As an alternative to photopolymer plates, has laser engraving been discussed
on this site? There are machines now that will take a Postscript file and
engrave it into hard plastic; I list a few websites below. It strikes me
that though the purchase price of one of these machines might be high, the
plastic material one used subsequently for plates might be low, and the
machines can serve other industries as well.
- on http://www.epiloglaser.com/materials.htm under engraving you can read:
"With adjustable speed and power settings from 1 to 100% and dpi settings of
up to 1200, you can set the engraver to print with as much depth and detail
as you need"
and under laser basics:
"vector cutting is a continuous path that follows the outline, or profile,
of an image. Vector cutting is normally used to cut completely through
materials such as wood, acrylic, paper, etc. It can also be used for quick
marking of characters and geometric patterns."
"It is possible to mark bare metal with a low power CO2 laser system using a
two step process. Simply apply a metal marking solution, such as Cerdec, to
the metal and let it dry. Laser engrave you image onto the metal, and wash
off the solution for a permanent metal mark. "
"The Legend line of laser engraving and cutting systems can engrave at
resolutions ranging from 200 to 1200 DPI"
"higher power will produce deeper cutting or engraving. Adjustable in 1%
increments, the power can be controlled either from your computer or from
the control panel on the engraver"
1200 dpi, variable depth, vector cutting all sounds interesting
