  1. Save materialFlint Group Narrow Web helps to reduce material cost • When printing on synthetic substrates how to get adhesion? • Adhesion through chemical bonding • Ink resins react with surface of substrate • Surface tension of material needs to be higher than the ink to achieve good lay & physical contact

  2. Save materialFlint Group Narrow Web helps to reduce material cost • Corona treating of material • Will create reactive groups in top micro-layer of material that enhance adhesion • Will increase surface tension that can enhance lay & physical contact between ink & substrate • When treated in-line just prior to print, corona treatment will burn away plasticizers or other additives that are harmful for adhesion • Reactive groups will not remain on surface and will diffuse into polymer with time • Thus corona treating will only last 3-6 months

  3. Save materialFlint Group Narrow Web helps to reduce material cost • Top Coated material benefits • Will create reactive groups that can be tailored to enhance adhesion • Will increase surface tension that enhance lay & physical contact between ink & substrate • Reactive groups of coating will remain on surface Positive effect will remain over long time

  4. Save materialFlint Group Narrow Web helps to reduce material cost • Disadvantages with Top Coated • The top coating has no adhesion to material, it’s impossible to get ink to adhere • Some type of top coatings are not compatible with printing inks • Poor applied top coat makes ink pinhole, not having good lay • Top Coated Materials are 10-20% more expensive

  5. Save materialFlint Group Narrow Web helps to reduce material cost • New universal inks works better without Top Coating on synthetic material • Excellent adhesion on known substrate structure • 30% cheaper material • Better performance with print quality (solids with no pinholes) • Will require corona treatment in line • Examples based on customer experience & internal testing: • UvoNova • Flexocure Gemini & Flexocure FORCE • Uvoscreen • CombiWhite • Hydrofilm 4000

  6. Universal Inks improves profit

  7. Save MaterialModern UV Flexo inks helps to reduce material cost • When printing UV Flexo on paper substrates how to get good gloss & strength? • Historically UV Flexo have required top class paper substrates with high gloss coating to function. • Paper structure is not always closed and High Gloss Papers also absorb thin liquids • Absorption of monomers & photo initiators result in • poor gloss, • poor print quality, • set of in press even at low printing speeds

  8. Universal UV Flexo InkCross Section Of a Coated Label Paper Some UV flexo Inks absorbs easy into paper Flexocure Gemini & Flexocure Shows excellent Hold out Coating (Single/Double) Reverse Side Treatment

  9. Save MaterialModern UV Flexo inks helps to reduce material cost • What will good hold out bring me? • Much better gloss, colour strength • Better print quality , sharper dots • Consistent print quality irrespective of press speed • Possibility to use cheaper paper types • Consistent quality even if paper batches are changing

  10. Save MaterialWhat will good hold out bring me?

  11. Save MaterialModern UV Flexo inks helps to reduce material cost • How much does this improve my profit? • Lower cost for equivalent gloss / print quality (cost index is Cast coated 100, On-l MC 71,8, Off-l MC 87,5) • Higher productivity as 1 ink for all substrates / papers • Every hour press is not running increase “overhead” cost per job that do run (best estimate is 100 - 150 € per hour) • Every time press are washed 0 -0,5 kilo of ink is wasted. Per unit! (best estimate : 5 - 10 € per unit & intake)
