Transparency and Soft Edges
Creating Transparency for Layers
http://www.image2output.com
The MATRIX tab provides the same functionality as this tab, but uses a
different input method. See below for more details on complex transparency
and examples of color transformations.
‘Matrix’ Tab (Transparency, Trapping)
Use this dialog tab to define complex transparency settings which may
also involve color transformations. This tab provides the same functionality
as the COMPLEX tab, but uses a 2-dimensional matrix for specifying
transparency values.
How to Specify Matrix Values
You can specify values ranging from –100 to +100. Use negative values
to subtract colors from a separation, use positive values to add colors to
a separation.
To modify a matrix value do one of the following:
• Double-click a matrix box, then type the new value.
• Click the field once, then edit it (e.g. delete using BACKSPACE).
• Click the field once, then modify the value by dragging the slider up
or down.
You can use the TAB key to select the next matrix box and SHIFT+TAB to
select the previous box.
How to Read Transparency Matrix
This matrix reflects the fact that transparency is the result of merging the
active layer (FOREGROUND) with the layers behind it (BACKGROUND).
Each color separation of the transparent layer can be created by adding
or subtracting percentages of the FOREGROUND and BACKGROUND separations.
The figure below shows the matrix of a 100% opaque layer.
