1 Standardisation update and Paperdam group PPA s Paper Profile working group 11th of February 2011 London Jouni Marttila / Sappi Fine Paper Europe Gerd Carl / UPM Luc Lanat / StoraEnso

2 Paperdam In 2008 group of people from different European paper manufacturers gathered to discuss ISO and especially the role of paper in standardization First meetings took place at IGT office in Amsterdam thus PAPER manufacturers meeting at AmsterDAM = Paperdam Paperdam is open for all paper manufaturers Check: 2 The Paperdam Group

5 Paperdam - Our targets We try to help ISO stardardization especially from paper point of view Paper is important part of ISO stardardization however paper itself should not be normative standardized in printing standards (so called ISO compliency) Please see Paperdam ISO compliant paper statement from: / downloads / Paperdam_ISO_compliant_position_ pdf We try to promote communication of paper properties and printing standardization ISO TC 130/ NWI proposal: "Communication of optical and surface properties of printing substrates... We try to help in standardization of optical measurements of paper and print 5 The Paperdam Group

6 Paper categorisation Paperdam Group supports the publication of recommended ICC profiles and characterisation data for each of their paper grades However each member decides themselves how to communicate these recommendations 6 The Paperdam Group

8 Two parallel issues Color management in world of standards ISO standards ISO ,2,3 ISO ISO certification Methods to reach standards PSO (Process Standard Offset) G7 North America Real world colour management Standard ICC profiles: ECI ICC profiles / Fogra characterisation data Gracol/SWOP ICC profiles Day-to-day issues reaching proof to print match 8 The Paperdam Group

11 Developments ISO There has been very active discussion about how to develop ISO /2/3 At the moment there is basically two proposals for updating the ISO ,2,3 - series 1. Updating the current version with main differencies on paper grouping ( European approach ) 2. Totally new structure based on process agnostic approach ( North American approach 11 The Paperdam Group

12 Developments ISO Earlier 4 papergroups approach: 12 The Paperdam Group

13 Developments ISO Process agnostic approach Each data set based on different outer gamut Cover the whole range of printing in logical steps based on real data 13 The Paperdam Group

14 Developments ISO Paperdam proposal based on paper matrix Paper properties in closer focus: Surface properties based on gloss and roughness Impact on print density and dot gain both can be combined in a surface index where gloss is higher valued Paper shade: L*a*b values contain 3-dimension thus difficult to use in categorisation CIE Whiteness is a good measure for the whiteness of paper with a focus on the yellow/blue axis. Paper industry needs a way on how to evaluate which printing condition applies to their products. The measurement methods proposed are standardised, well possible to calibrate and in use globally The paper matrix allows to "categorise" in order to find the right printing condition 14 The Paperdam Group

19 6 paper groups / 8+ printing conditions 6 Groups give direction for the creative world the 6 groups define the minimum amount of groups to characterise the different print substrates in offset method, characterisation data sets used are chosen from the largest available colour gamut as part of the annex to revision of they give guidance for the creation process and use of proofs until the substrate group is preselected the relevant aim values of the characterisation data is valid for informative proofing If print substrate is known in the process, the specific aims for proof and production should be chosen from one of the 8+ printing conditions paper manufacturers recommend the printing condition (PC) the selected PC minimises the deviation from the aimed colour to be reproduced gives the printer a specification for process control includes specific needs of production methods (dot gain, screening method, etc) 19 The Paperdam Group
