The laser-engraved phenolic prints well and, at least in my experience, is comparable to photopolymer plate. The phenolic is dimensionally stable and
remains completely flat even after engraving, print runs and wash-ups. The surface is extremely smooth, slippery almost, so I had to stay with a stiff ink
(Lewis Roberts Inc. Special Black, from Graphic Chemical & Ink). Another minor caveat: these non-standard materials all come in thicknesses related to
other industries (carpentry, construction, etc.) so backing them to achieve type height is tricky.
The K-3 or particle board, by the very nature of its manufacture (heat pressed sawdust binder mixture), does not give a very fine line for printing. Edges
softened a bit. Also, as a wood product, it is not dimensionally stable. I tried to 'insulate' several engraved particle board plates by coating them
with white shellac before starting the print work. Particle board's advantage: it's cheap and comes in 4 foot by 8 foot sheets.

I was under the impression (CO2?) lasers could cut most metals but not
copper because of refection problems. What kind of laser were you using?

Interesting group. Right down there at the essence of it all.

every solvent except "highly polar solvents such as acetone, and MEK, ozone,
chlorinated hydrocarbons and nitro hydrocarbons." Baby oil, ie white mineral
oil, is fine.
