Congratulations on your purchase of UJF-706 optional roll unit. This manual describes tips for using UJF-706 with the optional roll unit easily and stably. Especially handle 25 m-thick media with care because it is extremely delicate. To use it, please under- stand the characteristics of the media well and use the optional roll unit comfortably.
About Media Media type Various media can be used on UJF-706 including PP film, PVC, Tarpaulin and FF. For details, see the operation manual of UJF-706. This manual explains notes for thickness and elastic force of media. Thickness (The machine specification is 25 μm to 1 mm) To use thin media of 50 m thick or less, take a stretched one (OPP).
You can print on the media shown as the figure, however, you may have to widen the head gap (The image becomes blurred) or the media may cockle during printing. You should not use such a media, which is unfit for UJF-706. Check the media to be used, and use them depending on the conditions.
