A claybord is often used as a way to get more depth and contrast in a painting or drawing. Its basically a thin layer of clay spread over some particle board. The artist would scrape away the areas that would be darkest giving them more depth before painting over them. There are other uses too but thats the main one. I figured since its just clay it would be fine to pop into the laser and the results where pretty good. The level of detail is amazing even on lpi. I need to do more tests to see if i can get more contrast and clean it up a little but for just guessing im really happy. One problem iI did run into which you can see int the photo is the wavy lines. My guess is its clay dust that is pulled over the photo from the extraction fan because when it was only partly done the detail was so good i could see the checkered pattern on her shirt but as it got farther along it started to faid. There really isnt any smoke at all or smell which is nice.
i ran a few tests, the dark b’s are all the way down to the particle board and i got that by going full speed and 90 power. The image was done full speed 80 power 340 lpi vary power. Curios to see how converting it to dots works or maybe a slightly smaller image to see if the dust doesnt ruin it. I sprayed a coat of clear lacquer because it will crumble if you touch it and you will lose your shading which i did deliberately on the middle B. All in all not bad but more testing required.
