Digital Imaging
Provides a comprehensive practical guide to the entire digital chain, from capture -- with coverage of digital cameras, to output -- with extensive information on image adjustments and colour management.
TABLE OF CONTENTS Digital Imaging
Chapter 6: Managed Workflows
Aims
-
To offer a resource of technical information about colour workflows.
-
To develop an understanding of the procedures involved in producing printed outputs that match colour expectations.
-
To develop knowledge about the ways that managed workflows can influence colour.
Objectives
-
Research a range of managed workflows using the input and output devices available.
-
Analyse and evaluate the effectiveness of the workflows implemented and exchange ideas and opinions with other students.
-
Personal response - produce a series of digital ouputs that demonstrate the outcomes of the workflows investigated.
Introduction
The purpose of a colour managed workflow is to endeavour to get one device to accurately represent the colour of another device - or perhaps the colour of the 'original'. As discussed in the previous chapter, there are many reasons for inconsistencies in colour reproduction to occur. Different devices represent colour differently, depending on whether they are an RGB or a CMYK device - whether they use inks or light to 'manufacture' their colour. In addition each device has its own range of colours that it is capable of reproducing, some having a large colour gamut others possessing a quite restricted gamut (see Colour gamuts, page 68).
Implementing a workflow
Setting up a workable system of colour management which will deliver consistent results - in effect creating a managed workflow - requires either the first or both of the following:
-
Calibration of devices. This needs to be addressed at regular intervals as all device capabilities and performances will...
