Choose separation quality colors

Before starting separating your design, choose the separation quality type:

  • Smooth separation: Gives smoother and seamless in gradient separations (limited to 15 channels)
  • High precision: Gives precision in detail separations

Select colors

From picker

The fastest and easiest way to create a color filter is double clicking with on a color that you wish in the original image and the separation channels will be done instantly. See below separations done with this method and the results on the separations screen on the right preview. The channel number will be created as S-1, S-2 etc.

From new channel

Another way to do it is to create a new separation from channels options. Create a new channel from  or with Cmd+N.

Back to the original image, click on a color you wish (with the cmd button pressed), and the separation for that color will be created on the separation screen. Searching for surrounding colors in the separation channel you can select it from color picker. Or using Shift + ⌘ Cmd + click  (windows: Shift + Ctrl + Alt + click) on the desired color to set center color. It will select the new color in the image and change the new channel in the separation screen. 

Create separations


Lowering the color separation tolerance the color selection will be reduce in the lower percentage in the separation.

Tolerance 49

Plain Ink

Working with 'Plain ink' it converts separation in 100% grayscale and creates flat separation, ideally for spot colors and background designs.

Color Channel Groups

Grouping the separation joins color separations in one group to be independent in color mix with other channels, which allows different color combination after separations. Here is the example of grouping channel when having 6 groups:

  • Group 1 - Here the brown color separations are groped together because we want to allow color mixes.

  • Group 2 - The salmon color we add in a single group to be able to not be mixed with another channels.

  • Group 3 and 4 - The yellow colors are separated in single groups so they will perform independent.

  • Group 5 and 6 - Same as for yellow colors. The bluish colors should be independent.

Channel Mask

Working with alpha channel mask in your image you can exclude the color separation in the masked area. The white of the alpha channel is detected as mask. 

In the plug-in you can exclude the separation from the option 'Mask' where you can select the alpha channel mask.

Once the mask is applied, the separated color will be removed from the separation.

Using the inverted option, the mask selection will be inverted and applied to selected color.
