Hey Guys,
Generally, I rewind any banner material that is reverse wound as I tend to do longer runs and find that running it reverse requires too much baby sitting. I use alot of Sihl materials and all their banners come reverse wound, so I am used to spending a fair amount of time rewinding it using my laminator. Kind of a pain, but I'd rather spend the time rewinding and let the prints run autonomously. (If anyone has some better methods of re-rolling I'm all ears!).
Anyways, thus far adhering to the above practice, I have never really had many problems with banners. Last night I got a rush order from one of my regulars for some banners. I had just picked up a roll of the 3109 double sided material and figured: "great, I won't have to re-roll it." Here's the bizzare thing, in the process of re-rolling my previous rolls of single sided material, I never noticed how much the material sticks to itself. Re-winding it breaks that initial high level of stickiness and makes it flow off the roll much better.
Long story short, I loaded up the 3109 out of the box, pulled it through to the take up reel, set my media comp and started printing. I kept half an eye on it through the window of my office and all looked okay. A few hours later I come grab the prints and to my horror, I have a very regular on off banding pattern. I ran another banner off and watched it like a hawk. I noticed that the stickiness of the material caused the media to feed incorrectly once it had advanced past the section that had been sort of pre-released by me when I load the machine (the first 8-10 inches). Once it got past the section that had been unstuck in the loading process, the material would sort of bind up and not flow off the roll correctly. In cross section, the leading edge of the media came off the roll more like a chord through the roll rather than a tangent. It just puts too much load on the grit roller motors and F's the media comp to the point where you can't really chase it down during the print!
Anyone else have similar issues? Also, has anyone devised a quickie way of re-rolling banners. I hate the way I'm doing it now, although its not the worst thing in the world.
