Creation of Separations
Hybrid Designs Separation
Hybrid designs are photographic image files in color space RGB, LAB, or CMYK with Alpha channel(s) in the format PSD, PSB, or TIFF. Load your image file in nT Multicomia and create your mask separation with separation tools available in nT Multicomia for your hybrid design. The superposition coloring method 'Pigment' will be applied in the extra channel of the hybrid design.
Quick Color Separation
The fastest and easiest way to create a color filter is double clicking with the color selector on a color that you wish in the original image and the separation channels will be done instantly. See below the separations done with this method and the results on the separations screen on the right. Or, create a New separation (cmd+N) from Separation options. From the Filter, options choose to apply the Colour filter (cmd+alt+E). Back to the original image, select a color you want (cmd+click) and add cmd+alt+E, 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 the color picker that opens when clicking on the RGB color patch. Or use Shift + ⌘ Cmd + click color selector (windows: Shift + Ctrl + Alt + click) on the desired color to set the center color. It will select the new color in the image and change the new channel in the separation screen.
Hue-Lightness & Hue-Brightness Separation
Display the filter options to select, or use this keyboard combination (⌘ + Alt + L or ⌘ + Alt + B). Then click the color selector on a color, pressing ⌘ to choose the color from the Separations window. Pressing the Shift+Click color selector on the color, we add it to our filtering and using the keyboard combination Shift+Alt+click color selector on the color, we take it away. Pressing Shift + ⌘ Cmd + click color selector (windows: Shift + Ctrl + Alt + click) on the desired color to set the center color. The Lightness and Brightness separations show very similar actions: Color curves, Intensity, and Output percentages can be adjusted in both separations.
This filtering method is used to separate concrete images such as photos, wood, or marble. Choose the Component Filter from the Filter's options, once created a new separation. You can also use the keyboard combination: ⌘ + Alt + C. Modify the Cyan, Magenta and Yellow Components to get the desired color.

Alternatively, press the keyboard combination ⌘ + Alt + K. Pressing the Shift+Click color selector on the black color, we add black color to the filtering and using the keyboard combination Shift+alt+click color selector on the black, we take it away.

This filter method is used to add separations made in Adobe® Photoshop® or to use channels as separation masks. The component channels can be used or embedded Alpha Channels. Select the Channel Filter from the Filters options. Alternatively, press ⌘ + Alt + H. Bear in mind that the channel must already exist in the source image file.
This filtering method is used to create masks or add separations to existing separations. Select the Separation Filter from the Filters options. Alternatively, press ⌘ + Alt + H. Notice that in order that a separation can be filtered, it must come before the Separation filter, otherwise, this action cannot be fulfilled. Select the separation you want to move on the list of separations, and click on the separations button. We select the channel from the Separation tab, and we adjust it from the Levels tab.
Color Palette Filter
This filtering method is used to select colors in the image with a color palette. Select the Color Palette Filter from the Filters options. Alternatively, press ⌘ + Alt + I. Add colors to the Filter by clicking the Shift+click color selector on the Original Preview Window and, if we need so, remove it with the combination Shift+alt+click color selector. When a color of the image is selected it is highlighted on the Palette. You can select and unselect colors from the Color Palette or by clicking on the Original design. You can modify the selected colors in Intensities or in the Level. Further modification on curves and levels can be done as given options and explanations in the chapter Manage Separations and Curves.
