banding on grenadier
Hi. I am hoping there is someone out there who can give me a couple of pointers. I am getting banding, it is slight but annoying. it is repeating every 6mm or so and is more obvious when printing solid reds or yellows, I dont know where to start to isolate the problem as I have only had machine a couple of months and it turned out that my operator knew (they’re gone!!)less than me (very frightening). The machine was printing fine and has new heads on the Black, Cyan and Magenta with test prints showing no problems.
Should I be looking at feed speed, print speed, ink flow? I am running the original roland colour rip which seems fine for our needs until I can upgrade to wasatch. so although its not ideal for newer profiles I am fairly sure this isn’t the problem as it was running fine before.
If theres anyone who can help save me getting my engineer/millionaire in, I’ll owe you a pint next time you’re passing through my neck of the woods.
thanks.
Adrian.
P.s sorry for no profile pic, it slipped my mind completely. -

Its probably the feed speed that needs calibrating, That is the usual cause of banding.

Thanks, that was my gut feeling. At least I have a starting point now.
I will go and have a play, my engineer says it is ink starvation but for some reason I am just not convinced.
Beer is on me. (drink1) -
In Wasatch you can change the calibration for different materials to sort the banding don’t know if same control is available in your RIP would suggest reading the help pages for your RIP

Thanks for your advice, thats actually very interesting as I am about to upgrade to wasatch in a few weeks, that is if my engineer doesnt keep taking all my profits. It turned out to be a damper problem, I thought they had all been changed when we first got the machine and it was serviced, they hadn’t!!!! MORE FOOL ME. Thanks for your help anyway.
