Adobe illustrator 10 Manual Do Utilizador

When you prepare artwork for printing, a number of marks are needed for the printer to 
register the artwork elements precisely and verify correct color. These marks include 
elements such as crop marks, registration marks, star targets, calibration bars, and labels. 
The Separation Setup dialog box enables you to add these marks to your separations. 

Printer’s marks 
A. Star target B. Label (film only) C. Registration marks D. Black overprint color bar
E. Crop mark F. Gradient tint bar G. Progressive color bar

In Illustrator, the printer’s marks are either turned on or turned off. You cannot choose 
individual marks to be placed around the artwork. The Use Printer’s Marks option adds the 
following marks to the separations:

Registration marks and star targets Illustrator places around your artwork two types of 
marks that the print shop uses to align the separations: registration marks and star targets. 
Registration marks are the most commonly used marks in printing, because they are easy 
to line up accurately. Star targets are harder than registration marks to align, but they are 
extremely accurate.

Labels Illustrator labels the film with the name of the file, the line screen used, the screen 
angle for the separation, and the color of each particular plate. These labels appear at the 
tops of the images. 

Crop marks Illustrator places crop marks at the edges of the printing bounding box. If the 
Japanese Crop Marks option is selected in the General Preferences dialog box, a double 
set of crop marks is displayed. 

1 In the Separation Setup dialog box, select Use Printer’s Marks.

2 Specify another separation option, or click OK.

Setting up a separation involves choosing the separation options and then printing or 
saving the file.
