Print Properties
• The goal of the Print Properties Committee is to establish jointresearch projects, and teams addressing needs of Graphic Arts, Printing and Publishing– Including calibration, metrology, substrates, inks, alternate
screening technologies and the applicability of metadata in production workflows.
• Teams of Experts
• To work with Global Standards bodies to insure consistent requirements and research projects

Current Projects• NEW ICC Profiles Utilizing G7 methodology - implementation
• 2 New SWOP profiles / GRACoL Coated 1– Working with Adobe / CGATS / ICC Profile registry for PDFX4
• Need additional profiles: Premium News, SNC SCA, Gravure– Alternative Screening - testing for datasets– Metrology / Instrumentation
• G7 Print / Monitor / Proofing / Lighting for View booths
• Review for Improvement current processes– Proofing Certifications / Verification Programs - 6 months– Continue Proofing Certifications with SWOP/ GRACoL / SNAP…?
• Update Patches for Verification current UGRA/ FOGRA
• Monitor Proofing Certification / ADS / Verification Tools• Global Agreement

PPC Global Representation
• Global Standards Representation
– ICC• Profile Registry• Series of Reference Characterization Dataset
– ISO TC130• 12647-7 Proofing Standard / Proofing Verification Strip• Paper Classifications • Unity Profiles (Global Standards)
– CGATS/ FOGRA• CGATS TR003, TR005, TR001 • FOGRA 39 dataset

Need for Improved SWOPTR001 vs New SWOP#3,#5
• No More Text Web Paper • Proofs on Text Web ( not used)
• First pressruns could not replicate original SWOP press sheets
• SWOP proofs had many different flavors
• New SWOP needs: Raise the bar with Color Management• WHITER SUBSTRATES / THAN CERTIFIED• Different Inks ( ISO) / Substrates• CTP Plate Curves / G7• Different Metrology – New Backers Proofing:
• New Targets
New Targets - Grey Balance NPDC

SWOP Press Runs
• Press runs on Sheetfed / Web - were different!!• Multiple press runs to understand relationship of Web to
Sheetfed • Collected Data from the it8 7.4, smoothed - applied G7
methodolgy – comparing to CGATS TR001• Using the original CGATS TR001 - applying G7curve,
and adapting data from controlled press runs• Created SWOP2006_Coated3, SWOP2006_Coated 5

Proofing State of the Art 2007IDEAlliance Proofing Summit
• Verification of Proofs - USERS:
– New ADS - global verification patches
– Online proof check
– What’s needed?

Conclusion Proofing
• We will continue to update these new systems / procedures to insure reliable and stable results.
• Proofs can now be made with different ingredients measured with common aims and goals- remotely / globally
• Using metrology is somewhat uncharted ground, working with RIT, evaluating measured data we will continue to raise the bar
• Six Month reviews of the proofing process will remain in place to insure we are using the best methodology This system is adaptable to new profiles, or new measurement requirment
