Your choice of cushion mounting tape is crucial to achieving high quality printing whether it’s on boxes, shopping bags, beverage cartons or labels. The improvement in print quality using an open-cell cushion mounting product is shown below.

CushionThe open-cell structure of R/bak® cushion mounting materials has a greater resistance to compression set compared to typical closed-cell products.  Compression set is defined as the ability of the product to return to its original thickness after being compressed. R/bak materials typically hold 97% of their original thickness even after one million impressions.  Closed-cell competitor products typically maintain 70-90% of their original thickness.  This means that R/bak open-cell foams will provide the most consistent print results over long runs while making little or no adjustments.  Closed-cell products require multiple adjustments due to loss of impression.

Banding is the visible web direction variation in print results, typically in tonal areas that appear to be “gear bands.” There are many causes for banding including machine vibration and the design on the plate. If this problem plagues your work, this is a great time to try R/bak cushions, which absorb shock and reduce pressure, to determine if they can eliminate this defect.

If this article has made you curious about experimenting with tape, you should first ask yourself what issues do you face: Do you have long runs, are you unable to reach high line speeds, do you struggle with banding, is it difficult to achieve solid ink density while minimizing dot gain? Hopefully the information above provides some direction in your efforts to improve your print quality and effectiveness.
