Perf and or cut through issues. Jagged paper. What knife is best 45 or 60 degree.

I've been cutting quite a bit of decals and the edges are rough and slightly jagged. I've change the blade to an brand new one and I still get the jagged edge. I've been using Oracal Orajet 3651 and 3641 and I get the same result on both. Can this be a issue with the liner make up. The Oracal 3651 is a 90lb PE-Coated silicone paper and the 3641 is a 83 lb silicone paper. Also I was thinking of trying a 60 degree blade instead of a 45 degree blade to see if I get a better result. I will start trying other material options but until then what do you think?

Pictures of my issue

Here's two pictures of what I'm experiencing.

That's the nature of the beast when using these tiny blades to cut paper. You need a really fine point like a 60 degree that is super sharp for clean cuts.

I haven't used a Graphtec, however on my Roland I have found when doing the perf cut, that I experience this when I've got my cutting speed set too fast. If I slow it down (and use a 60 degree blade) it cuts much smoother. Perf cut is great, but I find you have to test and tweak each material type to get the best results because each one cuts differently.

Best I have used is a 45 deg CB15. The CB09 does not last very long and the cutting edge itself is much to small. 60 deg blades tend to destroy themselves fairly quickly also. I hang the blade out quite a ways. to the point almost the three quarters of the edge is out of the holder.

I perf cut alot. almost daily. And cause of that I buy about 5 blades from Ross every two months or sooner just for this.

Also I do 2 cuts when doing the Perf cutting. 1st a reg CC then about .050 to .100 out I do the perf cut.
