Click Cancel to return to editing the paint object without destroying the vector mask.
Click Yes if you want Canvas to convert the vector mask to a channel mask that can be edited
with painting tools (see "Editing channel masks" on page 510).
Using transfer modes
All objects—vector objects, text objects, paint objects, and group objects—have transfer modes,
which are like invisible filters that affect the appearance of colors. When objects overlap, the transfer
mode of the front object can change the appearance of the back object.
Transfer modes work with transparency effects, including opacity and transparency masks;
however, transfer modes can make objects appear to be transparent without reduced opacity or
transparency masks; e.g., Multiply mode lets underlying colors show through an object. The default
transfer mode is Normal; i.e., the colors of overlapping objects do not mix unless the front object is
partially transparent.
In addition to interacting with background objects, transfer modes can interact with the document’s
white background. When an object’s transfer mode is Screen, anything white replaces the object’s
color, so the document’s white background can make the object seem to be invisible.
For vector objects, apply transfer modes to fill inks alone or to fill inks and strokes together.
To change an object’s transfer mode:
1. Select an object and choose a mode in the Transfer Mode menu in the Properties bar or
Transparency palette.
2. For vector objects, select a Scope option for either the Fill or Fill & Stroke.
Available transfer modes
The following descriptions are based on objects with RGB colors with no other transparency effects.
Each mode is described in terms of the front object when the back object’s transfer mode is Normal.
Normal: Colors do not blend; the color of a front object hides the colors of all objects behind
it.
Multiply: Overlapping colors become darker. Black produces black. White has no effect, the
same as if a white object were not visible. White text, for example, reveals the background.
Screen: Overlapping colors are lightened. Objects with lighter colors increase the effect.
White produces white. Black has no effect, the same as if a black object were not visible.
Black text, for example, reveals the background.
