Need Help Printing Temperatures

[ewded]

So my prints are fine on thick material but cannot print bidirectional on oracal 3164 or similar 70micron media as it gets wavy on the printing platform and bidirectional printing looks awful in those places.

I know it must be a heating problem because I printed 3164 just fine a few months earlier but I cannot remember the setting.

Now I print on 30C pre 40C print and 50C post (86F-104F-122F) and room temp is 18C/64F

Tried standard vacuum instead of strong and only 2 pinch rollers on the ends, this helps somewhat but does not eliminate the problem.

Bidir settings are fine as the problem is present only on wavy parts, other parts are fine.

Someone got an idea of what temperatures should I use? Is there a rule of thumb for temperatures for different medias ?

that seems pretty warm....i use (pre) 33 (print) 34 and 47 (post)....
a little less post on banner materials etc....

Yep in the meantime I fount 30-30-40 works just fine. I was afraid on lower temps my ink will not cure, but it seems solid.

Thanks.

It's going to be different for everyone but the general rule is, go as hot as you can without buckling. For me, on regular calendared vinyl, that temp is usually 33 pre 35 plat and 50 post.

Thanks, I just read that bn20 has a fixed temp of 35 C so I guess this is a good starting point.
