Does static affect printing?

Hi,
I'm encountering problems printing on magnetic vinyl and static cling. The ink droplets seem to bead together resulting in banding and graining. Also, sometimes I can see patterns or stripes on the media, as if there is contamination but the media is clean.
I was wondering if static may the culprit.
I'm using a Roland Versacamm.
Any ideas would be appriaciated.
Thanks,
Graham

both the products are difficult surfaces to print on to. and vary wildly from make to make.
you could try slowing the head speed and a higher quality mode which will give the ink time to dry a bit between passes.

Thanks Chris,
The print is set to high quality, but I didn't try to slow the head so I'll give that a go.
The magnetic vinyl sheeting is sold my MDP and says it's suitable for digital solvent printing.

had a closer look and i think the ink is being rejected by the surface as i said diffecult type. like water on a polished surface.
you could laminate print vinyl on to the magnetic then print.
in answer to the static question yes static can be a big problem but normally shows up as a goasting mist.

i use metamark cling with very good results but that is on my VS printer that lays the ink down better that the dx4 head machines.

Thanks again,
Yes, I agree and was resorting to the laminate printing idea.

Agree with Chris , the ink has reticulated on the surface which suggests a very low dyne level , is the media very old as dyne level reduces over time also the may suffer from plasticiser migration.
Buy a cling specifically for solvent inkjet , it will come in a 1370mm wide format and will be treated to avoid this.

Cheers

i had this on the mimaki solvent the other day and the temperatures were to high, was fine at one end and like yours the other end, dropped the temp and all was fine,

yep i would always print onto vinyl laminate and mount onto magnetic. I would have thought just the weight of the magnetic going through the printer would have caused problem
