For frosted acrylic the barcode label has, for me, been on the frosted side of the sheet of material. If I’m wrong then my previous batch was wrong.
The last sheet of medium size had the label backwards and that results in very hazy reverse engraved projects that can’t be used.
Suggestion:
Can we get something on the masking to indicate the frosted side in the future?
I’ll have to verify any sheets I have left before using them just to make sure. A minor problem but good to know for the odd commission 
Thanks
