Just got my samples from Rowmark.
Chalkboard surface comes in white, black and green. Message board comes in white and black.
Comes in either 1/16" or 1/8" thickness.
Haven’t yet compared it to regular white cast acrylic and mat black acrylic for pricing but these look and feel pretty cool.
I threw the black chalkboard in the laser to see how it would raster…
Must be extruded since it didnt mark…(its a reflection in the pic…no color at all on the etch)
But I bet you could colorfill
First attempt was the old scrape off after dry method…acrylic wouldn’t budge.
Second tried colorfill with mask. Surface is not flat so tape didn’t mask well…
Also note the “H” in chalk still left on the board in 2nd pic. I wiped it off with my hand and it doesnt totally disappear unless you wipe it with a moist towel or sponge (in which case came off easily)…so thats sort of useful…
