Working with Workflows

Adding a Workflow

A new workflow is automatically added to the worksheet when a second image or color list is opened or dropped onto the worksheet.

To create a new workflow that uses the previous workflow’s data source, click the + button in the workflow region. This is effective for applying different profiles to the same source data.

For instance, if you are comparing two input profiles using an image:

Now the effects of two input profiles can be visually compared using the same source image. This also works on color lists. Turn on delta-E to have ColorThink calculate the difference between the two profiles’ rendering of the image colors.

Adding items to a workflow

To add profiles to a workflow:

1. Drag a profile from another ColorThink window or the Finder / File Manager onto the image or colors region of the workflow.

2. OR click the + button at the right edge of the workflow’s Workflow region and navigate the menu to select or open the desired profile.

ColorThink will also import files from your Maxwell account.

Take measurements using any of the supported measurement devices.

Any recently used files can be chosen.

Note: Dragging a profile into the profile region of a workflow will replace the current profile, “assigning” the profile to the colors or image. See “Assigning a Profile” in the glossary for more information on this important distinction.

Only profiles can be added to a workflow. Adding color lists or images to workflows actually creates a new workflow with the list or image as its source data.

Delta E comparison

Clicking the deltaE icon will open a comparison between two different points in the Worksheet. This powerful tool can be used to compare between the starting point where a pixel enters the workflow, to any point in the workflow as laid out in the Worksheet. Possible uses include:

Selecting deltaE formulae

When the delta-E column is displayed, the delta-E Units and delta-E Coloring popup menus are also available. ColorThink allows the selection of several different delta-E formulae depending on your preference. Selecting a new formula will cause an immediate recalculation of all values.

The color differencing formulae available in ColorThink are:

• Delta-E 1976

• Delta-E 94

• Delta-E 2000

• CMC 1:1

• CMC 1:2

• Delta-Lab

• Delta-LCH

• Delta-ab / Ch / Ec

Note: Altering the delta-E formula doesn’t affect the length or distribution of vectors in the Grapher. As the Grapher works in D50 Lab, all graphed color differences are effectively delta-E 1976 which is the simple calculation of the 3D distance between any two points. Delta-E coloring however, will alter the color-coding of the vectors drawing your attention to the shifts which are likely to cause the most problems.
