ISO 12647-2:2013 – Process control for the production of half-tone colour separations, proof and production prints

What is ISO 12647?

ISO 12647-2:2013 specifies the process control parameters for the production of half-tone colour separations, proof prints, and production prints using offset lithographic processes. This part of the ISO 12647 series is essential for ensuring color consistency, print accuracy, and quality assurance in commercial and packaging printing.

ISO 12647

The standard outlines the target values and measurement conditions necessary for maintaining uniformity in tone reproduction, color rendering, and ink density across sheet-fed and coldset offset printing systems.

ISO 12647-2:2013 offers a global reference for standardized colour control and predictable print output.

Scope and Applicability

ISO 12647-2:2013 aims to establish a common framework for color reproduction and print process stability in offset lithographic printing, ensuring reliable results from digital file creation to final printed output. It applies to all industry stakeholders involved in prepress, printing, and proofing workflows, including:

  • Offset printers and prepress facilities
  • Print buyers and advertising agencies
  • Color management professionals
  • Equipment manufacturers (press, plates, inks, proofers)

This standard is used to calibrate and maintain print systems, reduce production waste, and ensure repeatable, ISO-aligned output across runs and locations.

Key Definitions in ISO 12647

  1. Half-Tone Colour Separation: The process of converting continuous-tone images into dot-based images for CMYK printing
  2. Proof Print: A simulation of the final print used to verify colors and layout before mass production
  3. Dot Gain (Tone Value Increase): The increase in dot size from plate to printed sheet, impacting tonal accuracy
  4. TVI (Tone Value Increase) Curves: Used to measure and compensate for dot gain across tonal ranges
  5. Solid Ink Density: Measurement of the thickness of ink applied to paper to ensure consistency across colors
  6. Grey Balance: Achieving neutral greys through the appropriate mixture of CMY values

Structure of ISO 12647-2:2013

The standard provides technical specifications for:

Process Element

Control Parameters

Printing Conditions

Sheet-fed, heatset web, and coldset offset printing processes

Tone Value Increase (TVI) Curves

Recommended curves and tolerances for CMY and K separations

Primary Ink Solids

Target densities and Lab* values for CMYK solid ink patches

Secondary Color Solids

Lab* values for overprints (e.g., Red, Green, Blue combinations)

Grey Balance

Neutral density targets at different tonal areas (highlights, midtones)

Paper Types

Specifications for coated, uncoated, and newsprint papers

Measurement Conditions

Use of spectrophotometers under M0/M1 (ISO 13655) lighting conditions

Proofing and Verification

Criteria for digital and contract proof validation using color references

These requirements ensure consistent reproduction across different substrates, inks, and machines.

What are the requirements of ISO 12647?

  1. Calibrate CtP (Computer-to-Plate) systems and RIPs to generate separations aligned with TVI curves
  2. Establish a press fingerprinting process to determine optimal press settings and verify stability
  3. Use color measurement instruments (e.g., spectrophotometers) for inline and offline color control
  4. Integrate process control charts to track key parameters like solid ink density and grey balance
  5. Maintain proofing devices (e.g., inkjet proofers) to simulate production press output accurately
  6. Train pressroom staff in measurement procedures, tolerances, and corrective actions
  7. Conduct regular quality audits and revalidation tests to maintain ISO 12647-2 complianceRequirements of ISO 12647

Documentation Required

For organizations aiming to implement ISO 12647-2:2013 successfully, the following documents are typically required:

  1. Print process control manual
  2. Tone value increase (TVI) curve documentation and calibration logs
  3. Solid ink density measurement records
  4. Proofing verification reports and ICC profiles
  5. Press fingerprinting records and validation charts
  6. Grey balance and overprint control documentation
  7. Training logs for prepress and press staff
  8. Maintenance schedules for imaging and measurement equipment

What are the benefits of ISO 12647?

The print industry continues to evolve with innovations in hybrid printing, variable data workflows, and sustainability. Despite these shifts, color consistency and process stability remain non-negotiable, especially for packaging, publishing, and brand-critical print, ISO 12647-2 helps them to:

Benefits of ISO 12647

  • Ensure predictable color reproduction, reducing variation between proof and print
  • Reduce press setup time and material waste, leading to cost savings
  • Align print production with international buyer expectations and quality certifications
  • Enhance color consistency across different machines, shifts, and locations
  • Support client satisfaction and brand color integrity for packaging and corporate prints
  • Facilitate compliance with ISO 9001 quality management systems in print operations
  • Promote data-driven decision-making through measurable color metrics and process control
  • Improves training, standardization, and accountability across print and prepress teams
  • Enables participation in certified supply chains and print tenders requiring ISO-aligned output
  • Supports integration with G7, FOGRA or other regional color standards

ISO 12647-2:2013 is increasingly integrated into automated workflow systems, with cloud-based RIPs and inline color measurement tools using its parameters as a calibration base. It is also being incorporated into supplier qualification programs, especially for multinational brands that require global color conformity.

With rising demand for short-run, high-accuracy prints (driven by e-commerce and customized packaging), ISO 12647-2 provides the framework to ensure quality across offset workflows, regardless of run length or substrate type.

FAQ on ISO 12647

It is a process control standard, but it can be referenced in ISO 9001 audits for quality consistency in printing.

It applies to offset lithographic processes, including sheet-fed, web-fed, coldset, and heatset systems.

ISO 12647-2 is specific to offset, but other parts of the ISO 12647 series address digital and flexo printing.

It supports ISO 9001 by providing a technical process control model for print quality assurance.

Yes. Spectrophotometers, RIP calibration software, and press control systems are essential for compliance.
