Hey, GF fam. I’m new to all this and need some answers. I’ve agreed to help my sister out with wedding magnet invitations and they have been coming out a bit imperfect. Was wondering if anyone here know the reasons why I’m having these weird marks.
The only part I masked was the top side which shows the reflection. I did one sample engraved on the back and one engraved in front. Here are the results.
Any help would be much appreciated! 
Oh, and I used this kind of tape to mask.
Try searching the forum for “acrylic flashback”, there’s some great discussion.
I’ll say try “mirror flashback” too, this exact issue has a thread or two of its own.
On it, thanks!
I could be mistaken but I’m pretty sure that mirrored acrylic is extruded rather than cast and will not give you the nice engrave you’re hoping for. Flashback being a different subject of course, but I will say that for a time I worked with two-toned acrylic (also extruded) and am not a fan. It can come out a hot mess.
Thanks for bringing this up. I didn’t know it would make a big difference. I will definitely get casted next time. Yes, there was flashback… But there were some parts that looked like it was just melted due to extruded acrylics lower melting point.
