The NEW nyloflex® ACE – Customers’ Feedback “We printed 1, 000 ft of pet food bags without cleaning (normally we stop to clean after 500, 000 ft); We were able to run the job 175 fpm faster and saved 7. 5 hours in press time!” “As a leading printer of confectionary bars we ran 1, 500, 000 ft and no cleaning of the plates was needed. ” “We ran 70, 000 lbs of film substrate on the potato chips job with only one set of NEW nyloflex® ACE Digital where previously we needed to replace the plates after 30, 000 lbs. ” “…label printing job with the NEW nyloflex® ACE Digital ran 200, 000 ft, no stops for cleaning were necessary. ” “A difficult hygiene packaging job 650, 000 ft could be printed without stop for cleaning constant print quality over the whole production run. ” “ 110, 000 ft diapers job with showed excellent ink transfer and the reduced ink consumption for achieving target density. ” “High speed flexible packaging job, 1, 650, 000 ft printed without cleaning. ” 19

The NEW nyloflex® ACE – nyloflex® NEx. T Exposure Technology • Outstanding performance with HD Flexo screening • Designed to work well with both digital Round Top Dots as well as Flat Top Dots 20

Improving Solid Ink Density Combining Plate and Surface Screening Technologies

Topics • Surface Screening - Solid Ink Density • Surface Screening – Opacity • Flat Top Dot Approaches • Fit For Flat Top Dot Plates 22

Improve SID and smoothness • Basic advice: Optimize parameters • Harder plate cushion, more ink, substrate treatment, etc. 1. 2 1. 4 • Problem is that an improvement HERE may take away from THERE. . . 23

Minimize or control mottle • Better method: Surface Screening • In use for a long time • Many versions throughout the years, but idea remains the same – textured plate surface reduces mottle through better ink distribution and coverage • Screenings historically 300 – 600 LPI Use 90 -97% Tint in Solids Plate Cell Patterning Digicap Groovy Screening 24

What About White Opacity? Can Surface Screens Using Flat Top Dot Technology Improve Opacity With Solid Whites? 30

Purpose Gain an understanding of the optimum plate durometer, cushion tape and surface screening parameters to maximize white opacity readings at high press speeds. 31

Plates (High Speed Test) Plates – Digital (0. 067”) • FAM D and ACE D (Flat Top Dot) Cushion Tape – (0. 020”) • 3 M 1920, 3 M 1020 and 3 M 1820 Surface Screening • Microcell - 4000 DPI • 17 Patterns One Smooth Solid 32

High Values Of Plate And Tape Contrast Ratio Function 35

Values Ranked By Surface Screening Value Contrast Ratio Function 36

Second Test • Evaluate opacity using lower anilox volume and Flat Top Dot surface screening parameters. • Will there be a greater differences in opacity using lower anilox volumes? • Will this reduce ink consumption while delivering acceptable opacity? 37

Press Conditions Press – Wide Web Flexible Packaging Anilox – 440 lpi/5. 5 bcm Ink – High Speed Surface White Viscosity – 28 seconds Press Speed – 1200 ft/min. Substrate – Polyester 38

Coating Weight and Opacity Contrast Ratio Function 41

Conclusions • Flat Top Dot technology allows for a greater level of detail at the surface. • Surface screening reduced pinholes and increased the opacity. • Increasing the modulus of the cushion tape increased opacity. 42

Conclusions • Higher opacity levels were achieved using surface screening allowing for the use of lower anilox volumes and potentially eliminating the need for a double bump. 43
