Printing onto Silicone

Post by sdp80 » Fri Feb 22, 2019 7:45 pm

Trying to print onto Silicone but the ink easily scratches away. Also as the silicone bends the ink cracks immediately.

I have the LEF-12 with eco solvent UV inks. Would the eco sol UVS work on this application and is it possible to switch over my inks on the LEF-12 to the UVS?

Appreciate any help as I really want to get this working on the silicone.

With silicone, it depends on the time between it being made and the time you print it, as the material releases a chemical which makes the ink not adhere.

If mad next to the time of printing it works, you can also use a plasma pre treatment to get it to work.

None of the primers I have tried work.

The items are shipped from abroad so there is no chance of printing onto them soon after production.

I guess this means there is no chance of printing onto the material then?

Have a look at the plasma treatment route.

Hello, I have Roland LEF 300. I have literally tried everything possible to print onto silicone with no luck. In my expereince, only silicone sticks to silicone. We can pad print or screen using silicone based inks, a 2 part system. I would really appreciate more information on plasma treatment.

As Kai mentioned, with silicone it can depend on time since manufacture...so if you're struggling then that will not change unless you go to source and know manufacture times etc.
Plasma treatment isn't cheap but could work...would have to try!
