Introduction to ICC colour management

William Li
Kodak

The International Color Consortium (ICC) was established for the purpose of creating, promoting and encouraging the standardization of an open, vendor-neutral, cross-platform color management system architecture and components. The outcome was the development of the ICC profile specification.

Bio:
William is currently Color Technology Manager with Eastman Kodak. He brings a diverse background in engineering, physics, and systems design and leads the team responsible for developing core color technology in such products as Kodak ColorFlow Software, Kodak Proofing System, Prosper, and Matchprint Virtual.


Converting instrument readings into visual plausible colour measurements

Andreas Kraushaar
Fogra

Substrates such as textiles, ceramics and plastics have a higher level of sub-surface scattering (often visible as a halo round the measurement spot) in comparison to most paper-like substrates. The resulting colour measurements are not visually plausible and do not produce an acceptable visual match on conventional contract proofs or on a monitor display. In this paper a method will be presented how the established measurement conditions (in ISO 13655) need to be changed to allow for a visually plausible measurement.

Bio:
Andreas Kraushaar is head of the prepress division at Fogra, Munich, Germany. Within the prepress department he is responsible for research in the fields of imaging science focusing on colour management and image quality assessment. He is convener of Working Group 3 (process control and related metrology) of ISO TC 130 (Graphic Technology).


Using eciCMYK as working color space for Wide Gamut printers (nChannel, CMYK+)

Peter Kleinheider
calibrate workflow consulting
Prepress Digital

eciCMYK (FOGRA53) was released in August 2017, aimed at developing tools for a media neutral print workflow. However, we have not seen any adoption of this ICC profile. Only few experts have an idea of how to use it and even among them, the way to use it is in debate. Neither the Ghent Working group nor the Swiss PDF/X-ready association recommend the usage of this profile at the moment. When working with nChannel output devices in a PDF workflow but receiving PDF files designed for CMYK output, the path to process and apply color management to such files is full of pitfalls that can lead to dull colors. In case of "artful" use of transparency effects, suboptimal application of color management can lead to a change in visual appearance. We at PPD tried to overcome some issues in PDF Workflows when rendering to a CMYK+ color space by using eciCMYK as internal working color space.

Bio:
Peter Kleinheider is managing partner of calibrate workflow consulting and a central contact for publishing companies - from basic consulting to project definition and support to implementation according to defined requirements. For the company PrePress Digital he is responsible for PDF processing, color management, rendering and API interfaces.

Colour management on variable substrates

Steven Harnie
LMNS Expert group

Through evolving technologies, the digital printing market is continuously growing and does so very rapidly. Concurrently, substrates such as fabrics, ceramics, carpets and many other non-flats have been widely accepted by the industry. The printers used with these applications and the constellation of machines around them appear to live up acceptably to the expectations, but it is less straightforward to keep the production processes stable, correct for fluctuations and keep color reproduction within the tight tolerances that are imposed. A requisite switch of substrates, inks or printers can drive any print company into a real predicament. In these situations, it becomes clear that colour management and adequate software is crucial.

Bio:
Steven Harnie is an application specialist who helps digital printing companies, manufacturers and software developers by providing intelligence and solutions through application knowledge. Before starting as freelancer in 2012, Steven spent 15 years as a service engineer and worked at an overseas printing company as production manager.

Devstudio hybrid profiles

Massimo Ontani
Devstudio

This presentation will explain the innovative approach to optimize and calibrate those printing systems provided of White inks on 'non-white' surfaces, developed Devstudio and ColorStream. The profiles are called Hybrid because the color of the substrate is involved with the colorants to the definition of the gamut of the printer in relative colorimetry. The special workflow also allows to create profiles for different substrate colors by simply reading a single multichannel target on an initial color and then adapting it to the new color surface.

Profiling for of the many different production devices, substrates and ink sets needs smart processes and tools. Ink-limiting, linearization, characterization; handling a wide variation of color information and organize this data in a consistent and reliable way. How to handle different paper tints? Creating profiles for an absolute match or make it a product in a consistent appearance to a reference for reproduction of images and spotcolors. This talk points out some important steps that must be respected for a smart and dynamic colormanagement as we need it today.

The measurement and profiling of special materials: glass, leather, laminates, etc: problems and solutions, practical experiences

Andrea DeRossi  
Tecnologie Grafiche

The best practice for a good color calibration of industrial digital printers that print on non-paper substrates: glass, leather, laminates, ceramics and fabric, etc. Each material based on its specific structure, requires particular attention and preliminary choices both in the measurement phase of the linearization targets, and in the construction of specific customized targets for the process characterization. The correct and appropriate setting of the printing modes, as well as the measurement and optimization of the characterization data are the basis for correct color management by means of conversion and color data processing systems using ICC profiles and Device Link profiles.
