Banner Printing with Mimaki CJV30-130

Try bringing the temps down to 30 / 33 / 40. You may need to slow the pass rate down.

Thanks I will try that, I also note that in the set up thats being used, there are only the outside 2 pinch rollers being used across a 1370mm roll. Is that ok? I have also read the manual, if I have read it right, it suggests that with heavier thicker material, the media guides should not be used. Can that be right?

[Jamie Wood]

I’d use more pinch rollers if available. On 440gsm banner, we do use the media guides.

I have the CJV150 and it was setup 30-30-36 for the heaters.
Pinch rollers for banner I use all 6.

Hi Kev

Could it be your banner material is cold or fresh in from a delivery which can make the material cold?
Or perhaps stood on its end directly onto a stone or cold floor? A cold floor can make one side of the media cold up one side about a foot or two.
I know I am probably stating the obvious but when cool material hits the heaters it can sometimes cockle the media as it is fed through.

Sometimes it can be the quality of a material or the thickness/weight your using, but the 440grms that your using should be fine for this. So I wouldn’t imagine it to be the problem.

if this type of thing happens to use with fresh delivered material, I just tell the lad to feed through the first metre or so and put it onto the take-up system. that solves it because it’s pulling it taught through the machine preventing any slack from puckering up.

Thanks Robert.
