Well....perhaps I spoke a little too soon in my enthusiasm for this material.
I purchased 8 sheets of Premium Plus for a rush job and overnighted it so I could work on this job over the weekend. Well.....I just wasted my first two sheets of Royal Blue!!!
I"ve been cutting ThermoFlex that I had in stock for several other colors and did have some trouble in certain areas of the design....never consistent though???? I was using a 60 deg blade with .400 offset at 120 gmf at 20 cm/sec doing those. But, I was able to fix the problem areas because of the higher tack.
Before I cut the Premium Plus, I reinstalled the 45 deg blade which I just bought about 2 weeks ago and have only cut Premium Plus with it on about a dozen designs. Also, I installed a brand new cutting strip and reset my offset back to .250. The force settings and speed were the same at 120 gmf and 20 cm / sec. I then reduced the speed down to 10 cm / sec thinking that might help but no such luck.
As expected, the problem is in the tight corners and is not consistent from design to design. One part of the design will cut ok but then I cut the same design a second time and now it doesn't do well in that same area.
I will take pictures and post later when I get my camera.
At this point....I don't think I can trust this material to use exclusively. I am going to have to have something in-house that I know I can cut and weed...even if it is more difficult to do so and more expensive....and which has the higher tack that allows me the opportunity to fix problems that I cannot do with this material.
Everything else about this material I love....BUT this problem has to be fixed for this material to become the ultimate material it was expected to be.
Fortunately...I was thinking...and had some Royal ThermoFlex as a back up that I can use which is why I choose this color to start with...thanks to this forum....
UPDATE: Ok...the Royal Blue ThermoFlex Plus turned out to be ThermoFlex Xtra but it will have to do. I had to bump up my force to 140 gmf to make the test cut work. But, I had ZERO detail loss from the cut / weed process!! The material is not as easy to work with as it likes to pull apart AND there is NO TACK on this carrier. But I didn't lose any detail at all.
So maybe the actual problem has nothing to do with the presence of tack but rather the behavior of the material during the cutting process? Maybe it doesn't like to be cut as well as some other materials? Maybe to much give???
The presence of tack may just be the "band aid" that would help put pieces back in place that shouldn't have pulled up in the first place...everything else being set correctly.
Just my random thoughts at the moment......
