# CMConcatProfileSet

Contains profile and other information needed to set up a color world.

## Declaration

```occ
typedef struct CMConcatProfileSet {
    ...
} CMConcatProfileSet;
```

## Overview

You can call the function [NCWNewColorWorld](colorsync_manager/1805079-ncwnewcolorworld.md) to create a color world for operations such as color matching and color conversion. A color world is normally based on two profiles—source and destination. But it can include a series of profiles that describe the processing for a work-flow sequence, such as scanning, printing, and previewing an image. To create a color world that includes a series of profiles, you use the function [CWConcatColorWorld](colorsync_manager/1805087-cwconcatcolorworld.md).

The array specified in the `profileSet` field identifies a concatenated profile set your application can use to establish a color world in which the sequential relationship among the profiles exists until your application disposes of the color world. Alternatively, you can create a device link profile composed of a series of linked profiles that remains intact and available for use again after your application disposes of the concatenated color world. In either case, you use a data structure of type `CMConcatProfileSet` to define the profile set. 

A device link profile accommodates users who use a specific configuration requiring a combination of device profiles and possibly non-device profiles repeatedly over time.

To set up a color world that includes a concatenated set of profiles, your application uses the function [CWConcatColorWorld](colorsync_manager/1805087-cwconcatcolorworld.md) , passing it a structure of type `CMConcatProfileSet.` The array you pass may contain a set of profile references or it may contain only the profile reference of a device link profile. To create a device link profile, your application calls the function [CWNewLinkProfile](colorsync_manager/1804915-cwnewlinkprofile.md), passing a structure of type `CMConcatProfileSet`.
