I've been buying 1/2" cast acrylic from a distributor and have always gotten a perfect white frosted image when rastering. I just received a new batch and the image is very weak ang not nearly as visible. My distributor told me that the order was from a different manufacturer and that may explain the problem and he is re shipping using the old suppliers product. Two questions. Has anyone experienced anything similar and does anyone have a suggestion on how to improve the image on the problem acrylic.

Could they have sent you extruded by accident?
I haven't had that issue on clear, but some colored acrylics are pretty hard to get a nice smooth white mark initially. I would suggest playing with your power and try different focus heights. Sometimes being out of focus gives me a better mark.
Good luck!

I had the same experience with black, ad it turned out that it was cast but was a cheaper brand made in Malaysia. It came in an unmarked brown protective paper cover. The edges cut nicely but no glossy finish, it was more like matte edges. I stopped using them, and since have only gone for the brands made in the USA or Mexico such as Acrylite.

Cast smells sweeter when laser engraved. Extruded has a more pungent smell

You could also set a piece of it on fire. Cast will crackle, extruded will melt and drip flaming balls.

If you have a table saw. Cast cuts easier. Less melting
