Mold or bleed through? Or?

Anyone working with Siser Easyweed come across this? Pressed logos for customer Christmas appreciation gifts and found these spots about 2 weeks after. Tried cleaners, alcohol, bleach, etc. Any thoughts?

Odd and curious. What's the substrate it's on? I used to use a ton of easy weed and never saw anything like that. (I've mostly switched to a different brand that I like better, but still get it occasionally). Usually when you have dye migration (bleed through) it's a consistent change in color across the material, not splotchy like that. Unless maybe that's some sort of weird blend with just little flecks of polyester in it I don't think that's it.

We got these same “fisheye-looking” spots when laminating clear FCO letters to the front of white acrylic using Weld On 3. We were attempting a push-thru look using clear letters on white backer, instead of white FCO letters on white backer (which we do regularly on routered aluminum faces).
We guessed the cause was dust or contaminates between the plastics creating actual fish eyes in the watery Weld-On. We never figured it out, really. We just didn’t do it again.
May be totally unrelated to your problem.

It's pressed onto black canvas tote bags. What's the other brand you switched to if you don't mind me asking? I'm sending to Siser for answers as well.

I was skeptical at first but there's a (relatively) local physical store in Orlando that I was able to get and test some, and have since used a LOT of it over the past year and a half or so. It cuts with the same settings as the Siser, but weeds WAAAAY easier IMHO. The backing is not quite as tacky, but just right. Cuts super cleanly, I've done pretty tiny details with it on my Graphtec. Stays together when weeding, it's pretty easy to do multiple lines of fine text at a time. Nice hand to it, if anything it may be just a tiny bit thinner than the Siser, but they're close. The website sucks and I've never been able to get a physical color chart from them, but I can tell you that the swatch pics are reasonably accurate on a calibrated monitor from the 8-10ish colors that I've tried. I go through a lot of white, black, and tangerine. The latter is the best "golden yellow" IMHO, think like law enforcement "raid" shirts or the stencils on the side of a military ammo can. It's the right color for those sorts of things. Red clay is the only swatch I've found that's not quite right on the sheet - I'd say in real life it's the same color as a terra cotta pot. Oh and the neon orange really pops!


I've also used the flock and soft metallic, both of which are fine though I haven't used nearly as much I've been happy with it all. I don't think you'll be disappointed if you try it.

I will definitely check them out, thank you for the info. I'll reply if I hear from Siser.
