Adobe Illustrator CS4 - Manual (Page 57)

50 USING ADOBE ILLUSTRATOR CS4
Workspace
• You can activate only one artboard at a time, whereas you can create and display multiple crop marks.
• The artboard is indicated by visible but non-printing marks, whereas crop marks are printed with registration black
(so that they print to every separation plate, similar to printer’s marks).
Note: Crop marks do not replace trim marks created with the Marks & Bleed options in the Print dialog box.
Create crop marks around an object
1 Select the object or objects.
2 Choose Effect > Crop Marks.
Delete crop marks
❖ Select Crop Marks in the Appearance panel, and then click the Delete Selected Item icon .
Use Japanese-style crop marks
Japanese-style crop marks have double lines, which visually define a default bleed value of 8.5 points (3 millimeters).
1 Choose Edit > Preferences > General (Windows) or Illustrator > Preferences > General (Mac OS).
2 Select Use Japanese Crop Marks, and then click OK.
Measure the distance between objects
The Measure tool calculates the distance between any two points and displays the results in the Info panel.
1 Select the Measure tool . (Press and hold the Eyedropper tool to see it in the Tools panel.)
2 Do one of the following:
• Click the two points to measure the distance between them.
• Click the first point and drag to the second point. Shift-drag to constrain the tool to multiples of 45°.
The Info panel shows the horizontal and vertical distances from the x and y axes, the absolute horizontal and vertical
distances, the total distances, and the angle measured.
Info panel overview
You use the Info panel (Window > Info) to get information on the area beneath the pointer and on selected objects.
• When an object is selected and a selection tool is active, the Info panel displays the object’s x and y coordinates,
width (W), and height (H). The values for width and height are affected by the Use Preview Bounds option in the
General preferences. When Use Preview Bounds is selected, Illustrator includes the stroke width (and other
attributes such as drop shadows) in the object’s dimensions. When Use Preview Bounds is deselected, Illustrator
measures only the dimensions defined by the object’s vector path.
• When you use the Pen tool or Gradient tool, or when you move a selection, the Info panel displays the change in x
(W), the change in y (H), the distance (D), and the angle
as you drag.
• When you use the Zoom tool, the Info panel displays the magnification factor and the x and y coordinates after you
release the mouse button.
• When you use the Scale tool, the Info panel displays the percentage change in width (W) and height (H) and the
new width (W) and height (H) after the scaling is complete. When you use the rotate or reflect tools, the Info panel
displays the coordinates of the object’s center and the angle of rotation
or reflection .
