Rough Cut FC9000

[Goatshaver]

I've had this issue where I'm cutting through these stickers, with a new blade and after about 10-15 cuts they get very rough. Now I noticed when I checked the blade again there was a build up of ink in the space around the blade just inside of the the cap.
I'm thinking this is the problem causing the rough edges by not allowing the blade to spin freely.

Now I'm not even sure if it's possible to not have the blade holder tip touching the material to avoid this. Anyone have other suggestions?

What material is that? That seems to be dulling way to fast.

It's a 6mil rose gold holographic from Hyperflex.

This is the ink that builds up after about 10 cuts. I took the cap off the blade holder and pushed the blade out with my finger and out pops this ink buildup.
Not sure if maybe the ink isn't curing well. I did try one with a layer of matte clear ink and those cut fine. Same blade and no rough edges.

And for clarification it's not building up on the tip of the blade, it's just inside of the blade holder base. This black cap with shaft for the blade.

Is this with UV ink? Are you cutting immediately after printing? I've found that letting the UV prints sit overnight before cutting helps a lot with this problem.

Yes this is UV. These I had cut within an hour of them being printed. Doesn't that defeat the purpose of UV inks by letting them sit? (A major selling point is the fact it's dry right off the printer.)
I've done other prints that I've cut right after and don't have this happen.

It's been my experience with the UCJV330 that the ink needs to sit for a few hours. Particularly with clear. I've noticed that putting a panel into the cutter right off the printer will cause the rollers to leave marks in the clear ink, whereas leaving the panel sit for a few hours eliminates that problem. It works great with our workflow, as we typically do most of our printing in the afternoons and everything gets laminated (if needed) and cut the following morning. Might be worth trying, as we do not see that kind of ink buildup on the blades.

That is a serious amount of ink.
We cut all day long with latex and never see anything like that.
Maybe try letting it sit overnight before cutting and see if it still has the same buildup?
