  1. The Metro Users 2014 Ragy Isaac Dennis Cheeseman

  2. Is This Your Make-ready? Audit your process!

  3. Quality Steps • Calibrate: • Prepress: line-screen, profile, TVI, preset, etc. • plate-room • Press • Consumable • Human factor

  4. Agenda • Same digital dot Variability on plate • “To rub it or not to rub it” that is the question!

  5. Introduction SNAP Profile should be your standard RGB to CMYK Depends on consistent dot value SNAP changed the SNAP certification program this year to alert printers to issues with dot gain/loss

  6. Facts No ISO standard for Litho plates CTP plates loose dot values relatively quickly on press Variation is high in mid tones Gray bars are a gauge for controlling solid ink densities

  7. Solutions SNAP is attempting to create a standard thus to ISO Current rub back procedure: Is a rough but quick methods Need to be more scientific Need your help, we will provide the know how

  8. Evaluate the Plate-room • Less variability for the same input Highly Variable Precise Accurate and Precise Needs Linearization

  9. Image-setter • Less variability for the same input • To evaluate a machine, eliminate human

  10. Magnified Cyan TVI Form

  11. Image-setter Test Form • Each dot % will have 32 values • 40% dot example data: • 8 for each of the CMYK

  12. Image-setter Test Form • Each dot % will have 32 values • 40% dot example data: • 38.4, 39.9, 39.8, 40.6, 39.5, 40.8, 39.7, 39.8, 39.7, 39.9, 40.1, 40.9, 41.2, 40, 40.4, 40, 39.5, 39.1, 41.5, 39.4, 40.4, 40.9, 41.1, 41.1, 40.1, 42.3, 40.1, 40.7, 40.9, 41, 40.7, 41.1 • Which value is the right value? • Values range between 38.4 & 42.3 • Max – min = 3.9

  13. RIP, Image-setter & Processor

  14. Dot Loss! • “To rub it or not to rub it” that is the question! • What do you currently do?

  15. Recommendation • Run the previous test: • With or Without rubbing • Print on press • Collect • printed samples • the plates • Measure the plates

  16. SNAP’s Free Offer • You provide the data and instructions • SNAP will tell you how to setup your image-setter and dot gain
