Ensuring consistent colors in workflows is extremely important

If the same digital data is used consistently in a workflow, it can be assumed that the same colour data is present in the individual processes. In practice, however, differences arise as devices render colors differently. This also applies to different monitors used in the individual processes. The colors therefore need not necessarily look the same at each stage of a workflow.

Why do colors not match on different devices?

One cause of this is that input and output devices, such as scanners, monitors, and colour printers, use different methods to generate colors and are different in terms of their colour rendering ranges. So it may come to pass that the colors shown vary from device to device, despite having the same data. Theoretically, it is almost impossible to match colors "perfectly" to one another on different devices. For example, monitors have their own colour rendering properties and other unique features, such as aging. Given these influencing variables, colors are often rendered differently on different monitors.

In professional workflow environments, in which strict colour management is required, differences in the colour rendering of the devices used mean that it cannot be predicted whether the desired colour will actually be achieved in the end product. In addition, differences in employees' understandings of colour may amplify this problem and impair the end result.

When working with a shared colour space, uniform colour management is possible from the first work step. The most important challenge for a colour management system is to balance out the differences between various workplace settings (customer, designer, prepress, and printer) and differences between the devices used and to create an environment in which identical data always look the same.
