Today’s topics Standards, specifications, and methods– Why we need them– Why we are wrong ationMeasurementViewing3
Standards, specifications & methodsWhat do you want?4
StandardsIf you don’t set standards 5
Standardsyou won’t know what’s right.6
Standards (Not what you think) - ISOA document established by consensus andapproved by a recognized body that provides forcommon and repeated use, rules, guidelines orcharacteristics for activities or their results, aimedat the achievement of the optimum degree of orderin a given context.7
Specifications - ISOA detailed description of the criteria for a piece ofwork. Specifications for printing can includecharacterization-data, ICC-profiles, PDF preflightcriteria, calibration targets for the print process,etc.8
Methods - ISOA way, technique, or process for doing something.9
In simpler terms Standards– A car Specifications– How fast, mpg, which parts, what color Methods– How to assemble10

Document standardsWho built this?14
Document standards There aren’t any! But there are recommendations 15
Document standards - GIF 256 colors per file Websites Animations16
Document standards - PNG No CMYK support Websites17
Document standards - JPG RGB, CMYK, L*a*b* ICC Profile Lossy Compression18

Document standards - TIFF RGB, CMYK, L*a*b* ICC Profile Lossless Compression21
PDF recommendations22
PDF recommendations PDF/X-1a– Least flexible– CMYK only– No ICC Profiles– No transparency or layers– Least likely to cause reproduction problems23
PDF recommendations PDF/X-4– Most flexible– CMYK, RGB, Gray, Spot colors– ICC Profiles allowed– Transparency and layers allowed– Most likely to cause reproduction problems24
