UV Ink spitting

Postby Leadpress » Mon Dec 03, 2018 7:08 pm

Guys, I am having alot of trouble with UV ink spitting. I'm laying down a green solid on a 600-3.05 bcm. I've always used the same ink with the same anilox, but I don't know if it's the weather or what. I used a heat gun to get rid of the foaming and to help make my ink less viscous? It's working, but I alomost started a fire! LOL. any ideas????

You can purchase a viscosity reducer from most in suppliers I use Flint.

And a Lamella tip doctor blade will help.

If you are associating the spitting with the foaming, I would try a de-foamer first.
If you are associating it with viscosity, try a viscosity reducer first, whilst also checking that this batch of ink is in spec (hard to believe I know, but sometimes ink manufacturers make out of spec batches, and they can even get by QC on occasion).

Try Swed Cut doctor blades. They're great for UV inks!!!

I use 5 gallon bucket heater bands on my UV when I leave for the day and keep it warm until morning granted this is for pumping purposes.... It reduces the Visc greatly.... When I am going to run UV white from GALLON Jug I have had good success Submerging the jug in a sink of hot water to loosen it up prior to pouring it in my pan... Hope this helps

Thanks Buc and Donald. Great ideas. I actually did warm up my ink this week and it helped a great deal. I also used double blade/ Swed cut, and it helped out really well.
