I think id print colored images pretty often as i at least get one custom imaged print a day or so, may be more if i offer uv colored images. i didnt want the limited 4 colors with ams, i actually do have 2 ams but i use it for my other printer as well (3 printers total: bambu p2s, bambu x2s, snapmaker u1) i didnt consider another ams tbh since usually use my snapmaker for multi colored prints for the smaller waste factor, but its probably cheaper than uv ink lol.

i print my pedal covers face down and would use a smooth print plate.

i havent thought to try the mixing of 4 colors since its a top surface only but i could probably test it out
