  2. Plates and Plate imaging technology • Non-Vendor Specific • General Discussion • Hardware Considerations • Current Plate Technologies • Violet • Thermal • Technology • “Environmental” considerations • Viability as proper working tool

  3. Technology Comparison Violet Thermal • Lower equipment investment cost • More flexibility for redundancy • High PPH to meet throughput needs • Does not support true processless plate technology • Amber room lighting required • Small amount of effluent to dispose • Higher equipment cost (incl. CSA’s etc) • PPH depends on plate technology (wider range of mj/cm) • Supports “true Processless” plate technology • No effluent

  4. Violet • Single Page speeds of 90-400 PPH, depending on budget and automation • Can needs be met with one device? • Need redundancy? • Cost effective to buy 1 or 2 platesetter units, evaluate PPH throughput and redundancy needs • Violet plate technology • “Lo-Chem” - one processing finisher (gum) based chemistry • no water rinse required

  5. Violet Process Flow“Lo-Chem” Pre-press Press

  6. Violet – Low Chem Interim Evaluation Method • Existing processor modified for interim evaluation • Allows for temporary evaluation and easy transition, if needed. • Little to no disruption to in-line plate benders, transport, sortation, etc Fresh Water Rinse Finisher Finishing Solution

  7. Single Stage System • Smaller footprint & easier maintenance • May need to reconfigure in-line equipment to accommodate shorter processor • Simple system, 1 solution for development • Replenishment not needed to maintain bath activity • Eliminates: • Pre-wash water • Post wash water • Dedicated Finisher Dryer Pre-heat 1 Stage Finishing Solution only

  8. Double Stage System • Eliminates: • Pre-rinse water • Post rinse water • Dedicated Finisher section Dryer Pre-heat 2nd Stage 1st Stage Finishing Solution only Finishing Solution only

  9. Violet Low Chem “Deliverables” • Better environmental solution than traditionally processed plate • Run length and resolution suitable for broadsheet and single wide market • No need to control developer activity — simple, 1-step finishing solution • Low replenishment — in some cases just top-up with water; to replace evaporation • Improved chemical yield per unit • Minimized waste amount (less total volume) • No water for pre-wash, rinse • No need for finishing gum • Limited maintenance and cleaning efforts • Same handling as traditional CTP plates • Smaller footprint when using dedicated machine • Hardware is cost effective for capital budget • Reliable processing system, few moving parts , smaller footprint

  10. Thermal • Single page speeds of 70-300 PPH, depending on plate imaging speed , budget and automation • Can needs be met with one device? • Need redundancy? • Cost effective to buy 1 or 2 platesetter units, evaluate PPH throughput and redundancy needs • Thermal plate technology • “True Processless” • “Non-Process”

  11. Thermal Process Flow – Process Free Plates Pre-press Press

  12. Non-Process Operating Principle on Press Before Exposure Exposure Fountain Solution Applied Ink Applied

  13. Step2 Basic Mechanism of Operation On-press “development” of non-exposed area Step 1— Dispersion by permeation of dampening solution Step 2 — Reduction of adhesive strength Step 3 — Expulsion of thermo sensitive layer to start up paper Step1 Step3

  14. Non-Process Plate, after press run • Non-Process • Non-Process plate will have the same structure to deliver normal ink/water balance • Once “developed” by running on press with normal startup sequence, should run like a normal thermal Plate

  15. A A A Exp. Dev. Print Plate Visibility Image after Exposure Image for Printing Ordinary Plate Plate inspection Image after Exposure Non-Process Plate Exp. Print Plate inspection • Visibility okay for: • Job number • Crop Marks • Text/Font • Optical Bender (specific light ring may be required ) How to manage: Densitometry Screen Frequency Screen Angles

  16. “To Ink” Technology Ecomaxx-T Operating principle: Non-image area coating disperses when dampened by the fountain solution. Non-image coating releases from the the grained aluminum substrate due to ink tack/transfer The dispersed coating is moved by the ink to the plate, transferred to the blanket, then sheet and is then expelled out of the press in the start up waste sheets.
