Transparency and Soft Edges
Creating Transparency for Layers
Note the two highlighted diagonals and read this matrix as follows:
• CYAN is composed of 100% FOREGROUND cyan and 0% BACK-
GROUND cyan (and 0% of any other FOREGROUND or BACKGROUND
separation).
• MAGENTA is composed of 100% FOREGROUND magenta and 0%
BACKGROUND magenta.
• YELLOW is composed of 100% FOREGROUND yellow and 0%
BACKGROUND yellow.
• BLACK is composed of 100% FOREGROUND black and 0%
BACKGROUND black.
This is the matrix of a layer which is 30% transparent in all four color
separations:
This matrix reads as follows:
• CYAN is composed of 70% FOREGROUND cyan and 30%
BACKGROUND cyan.
• MAGENTA is composed of 70% FOREGROUND magenta and 30%
BACKGROUND magenta.
• etc.
A matrix containing values not located on the two diagonals (highlighted
in this figure) produces color transformations. See below for more details.
Examples of Complex Transparency and Color Transformations
By transferring parts of a color separation to other separations you can
produce various optical effects, e.g. improving the contrast or keeping
dark shades. Color transformations can be applied to the BACKGROUND
only, to the FOREGROUND only and to both.
