Industry Indicators Define & Simplify iso Draft Packaging standard targets consistency in Print supply chain By steve smiley International Standards Organization (ISO) and members of its Graphic Technology Standardization and Terminol- ogy Committee, approved a new work item (NWI), estab- lished a working group for 2013 (WG13) and charged it with developing a Schema for Certification for packaging supply chain partners. Action took place at the committee’s October 2012 meeting in Chicago. Work in progress can be seen as a follow-on to ISO-12647- 6, the recently released Flexographic Printing Standard. Requirements are being devised to improve workflows, ad- dress all types of packaging and include annexes for process control for each of the print disciplines used in our industry— i.e. flexography, offset, gravure, and digital. The focus is on providing tools for consumer products companies to use when selecting supply chain partners, with expectations of eliminating the current needs for each printer to comply to each CPC’s custom requirements. ISO’s policy document—now in draft form, as a result of the October meeting—will allow for provisions for each CPC to add its re- quirements for color tolerance, or in the case of Certificate of Analysis (COA) or Certificate of Compliance (COC), specific testing for different packaging. The goal of the team of packaging experts at ISO is to define and simplify requirements for the global packaging supply chain. The working document, created to date, is not be the “how-to” document, similar to Flexographic Image Reproduc- tion Specifications and Tolerances (FIRST); merely a set of re- quirements for supply communication. Dubbed, “What Packag- ing Needs from Standards Organizations,” it ’s presented here. 1. INTRODUCTION This International Standard lists requirements and related properties that shall be used to communicate the standards and processes between CPCs and the printer/ supply chain for packaging applications. This document is intended to pro- vide both a reference to discuss the standards needs of the packaging industry and a possible outline of the key features that need to be included in an eventual standard. 2. SCOPE This document, and any eventual standard, is to provide a common set of guidelines for the packaging industry to enable consistency in the package print supply chain. These guide- lines and their associated checklists are based, wherever possible, on international and national standards—and when necessary, on industry documentation. The appearance of the printed package is communicated through reference printing SPEAKING & SPECIFYNG STANDARDS The goal of the team of packaging experts at ISO is to define and simplify requirements for the global packag- ing supply chain • Communications: Reference printing conditions that include characterization data and/or ICC profiles define the relationship between the CMYK and CXF spot color • Instrumentation: Calibration and identification are key parameters • Color Management: ICC profiles, embedded in PDF/X files, communicate the customer’s expectation to the rest of supply chain • Pre-Flight: Specification shall be compliant to the Ghent Workgroup guidelines for PDFX4 - CMYK+Spot (www.gwg.org) • Proofing: Requirements are defined in ISO 12647-7, Graphic Technology—Process Control for the Produc- tion of Halftone Color Separations, Proof and Produc- tion Prints — Part 7 • Testing: COA/COC testing is designed to insure that all packaging components maintain the desired design intent and equity Effective prepress is contingent upon explicit communication between the buyer and all members of the packaging supply chain. 22 FLEXO january 2013 www.flexography.org
