1. Label definitions often include a left indent; this can be removed in the
Labels dialog by right-clicking and choosing Paragraph. Or you can modify
the formatting in a label document, as in (2).
2. Click the button for New Document to get a sheet of labels. They're set
up as a table, so be sure you have table gridlines displayed (Table | Show
Gridlines) so you can see the label boundaries. You can use any sort of
formatting in those labels that you would use in any other table.
3. The first thing to do is to make sure that the labels you have are not a
variant of some listed stock number. Often the stock number will represent a
label that is identical to a listed one except for color (clear vs. white,
for example), so you may be able to find a built-in definition that works;
it will probably be in the same number range. If you can't find a label that
matches what you have, you can create your own definition. Select a label
that's as close to yours as you can find and click New Label. The
illustrations show what the various measurements represent; enter the
appropriate dimensions in each box and then save the label definition with
an appropriate name (which should include the stock number). You'll find
this label definition under "Other/Custom."
