Proper glue to adhere laser printed paper to glass beads The setup: Trying to make custom fridge magnets that are a large glass bead (with flat bottom), printed paper circle with text or image, then a magnet.
So...
Glass
Adhesive
Paper (printed side up)
Adhesive
Magnet

Our attempts so have used super glue (cyanoacrylate) to bind the paper to the the glass. The results have been that the image/text on the paper bleeds or smudges. This surprised us as it was a laser printer which we thought would be pretty fixed. I think the super glue is acting as a solvent to the toner on the paper.

Main question is: What would be a better adhesive here to afix the printed side of the paper to the glass without running the print job (laser printer toner)?
Needs to be fairly permanent but also needs to cure clear and not yellow much over time.
A different glue/adhesive for the magnet side is acceptable and not the focus of this question.

Thanks,
There is a pretty big ‘cabochon’ crafts movement that sounds a lot like what you are talking about: Flattened glass bead + acrylic emulsion glue + laser print + backing.

The first video I Found on YouTube advised Modge-Podge Dimensional Glue, but I have no experience with the product, and would recommend an acrylic gloss medium, which will dry clear. DO NOT ADD WATER, you will only create wrinkles.

Here is the process: 


Trace out the exact size of your paper backing and cut it out. Do not touch the surface of the print with your fingers.
Wash the glass with rubbing alcohol, let air dry. Do not touch the back where you will apply the glue.
Apply a drop of the gloss medium to the back of the glass. 
Spread it out and make sure that there are no bubbles.
Place the paper on the glass with the printed side to the glue.
Press it down firmly and let dry. (30 minutes - 60 minutes)
When dry apply a second coat to the back of the paper to seal it (and especially the edges) and let dry.
Now apply third coat and attach magnet. Let dry. If you are feeling adventurous you can add the magnet without waiting for the medium to dry the second time.


A bit of extra advice: try not to use too much red in your design, because red dyes and pigment inks fade over time due to sunlight / UV exposure. I have experienced this in laser, some offset and most ink jets - even the 10-color art print versions. The only options you have are museum glass (that will reflect UV) or UV blocking acrylic emulsion. I use Sennelier Gloss lacquer with UV protection.
