Korographics

[Neyland]

What is the secret to printing on Korographics? I have the heat turned off, but I am still getting head strikes. Tension setting maybe?
It seems as if it varies from roll to roll. One roll, I have zero head strikes throughout completion, and the next roll I can't get through one panel without multiple strikes. I'm using the same settings everytime. What am i doing wrong here?

never printed on it, so really don't know, but sometimes the machine pulling on a heavy roll can cause this with banner material, etc...
might try unrolling some for slack.

Thanks Tony, I think that I am going to try with almost zero tension.

Korographics Abaco Beach

We have modified our Mimaki JV33-130 (Solvent Ink) to include a vacuum to the platen to hold the Abaco Beach Flat. The Vacuum is a shop vac and the printer does a beautiful job on Abaco Beach with this modification. Pre Heat Setting 0, Platen Heat Setting 0, Post heat setting 50c. No bumps humps or color distortion when the material lays flat.

PS, The fans Mimaki call a vacuum producer is not enough to hold this or for that matter other heavy medias flat.
