In Canvas, trapping is best applied to vector objects that use a solid pen stroke and solid pen ink color. The following limitations apply to trapping: •   Canvas will not create a choke trap for text. •   Canvas will not create a choke trap for a vector object that has no stroke or has a stroke that is not a solid pen stroke. •   Canvas will not create a choke trap for an object that has a gradient pen ink. •   Canvas will not create a spread trap for a paint object. To specify trapping for objects 1 Select the object you want to trap. In most cases, this will be a foreground object that touches a highly contrasting color. 2 Choose Object > Object Specs to open the Object Specs palette and click the Trap tab, if necessary. 3 Click the Trap Object check box, and then select the Choke or Spread option button, depending on the type of trap to create. 4 Click Apply to set the trapping option for the selected object. No change is apparent in the object on screen, because the trap is created only when you print color separations. To apply trapping to selected text:  You can apply trapping options to text that you select within a text object using the Overprint and Spread options in the Text > Style submenu. To adjust the trap size Before printing color separations, you can specify the trap size. Click Separations Setup in the Print dialog box to change the trap size value. Attaching comments to objects You can attach written notes called comments to any object in a Can- vas document. This can be useful for individuals and workers in groups who share documents. Anyone who works on a document can attach one or more comments to any object.
