First time poster, long time lurker... I started a new job and we are printing on lightweight material 115 gsm and 145 gsm. The media widths are about 3.5m and 5.3. We are using a custom built (by the manufacture) bulk feed mechanism going into a Uvistar pro8.
My original thought is that the bulk feed was out of alignment to the printer. Fixed that and had success for a while. Then the roll became smaller and obviously weighed less... We started having a lot of creases again... I aligned it all over again and I still get creases.
Second thought is the bulk feeder and the shaft can't support the weight of the bulk roll. As it gets smaller we seem to have more issues. -I can see the whole frame and shaft flexing under the weight of the bulk rolls on a 3" core. Could this be an issue? Is a 3" core too small? As it sits, the middle of the roll sags a bit.
Third thought, the rolls came with wrinkles?
Any insight or ideas would be appreciated.
