R/Bak Cushion Foams

Features & Benefits

Higher Print Quality

R/bak materials provide a high degree of surface conformity with minima increase in plate pressure. the result in lower dot gain, cleaner revers print, improved registration, fewer dropouts & higher quality impression at increased press speeds.

Reduces Dot gain

Utilizing R/bak Cushions behind the printing plate allows the pressure applied to the plate to be absorbed by the cushion rather than the corrugated surface, thus reducing physical dot gain.

Eliminates Board Crush

The R/bak Cushion mounting system provides wide process latitude without damage to the corrugated board, allowing for a finished product that truly stands out.

Improved Handling

Lighter thin plates with shorter processing times.

Increased Press Speeds Without Bounce

Eliminating bounce allows increased throughput & ends double strikes.

Longer Plate Life

With less than 2% compression set, R/bak materials reduce plate wear by continually absorbing impact.

Reduced Costs/Improved Profits

Less waste and lower component wear mean more impressions & lower costs for you.

R/bak Cushions can be provided on customer request.

            To attach a lead to polyester:

  Place duct or fabric tape onto lead. (optional)*
On sewing machine, attach lead through polyester.
Apply glue or sealer on sewn end. (optional)*

*Soft tape prevents damage to edge from stitching

            To mount plate to R/bak material apply mounting tape to polyester base. Be certain air bubbles are not present. peel back release paper.
          
            7
          With a curving motion, lay plate onto adhesive Surface. Be certain air bubbles are removed.
