Adobe illustrator 10 Manuale Utente

1 Choose Edit > Preferences > General (Windows and Mac OS 9) or Illustrator > 
Preferences > General (Mac OS X). 

2 Select Japanese Crop Marks, and then click OK. 

Select the object, and choose Filter > Create > Trim Marks.

Trim marks created with the Trim Marks filter do not replace crop marks created with the 
Color Separation Setup dialog box or with the Object > Crop Marks > Make command. 

When your artwork contains transparency, Illustrator performs a process called flattening 
before printing or saving the artwork. During flattening, Illustrator looks for areas where 
transparent objects overlap other objects and isolates these areas by dividing the artwork 
into components. Illustrator then analyses each component to determine if the artwork 
can be represented using vector data or if the artwork must be rasterized.

In most cases, the flattening process produces excellent results. However, if your artwork 
contains complex, overlapping areas and you require high-resolution output, you can 
control the degree to which artwork is rasterized. 

1 Choose File > Document Setup.

2 Choose Transparency from the pop-up menu at the top of the dialog box, do the 
following, and click OK:

Specify a Raster/Vector balance. The higher the setting, the less rasterization is 

performed on artwork. Select the highest setting to represent as much artwork as 
possible using vector data; select the lowest setting to rasterize all the artwork.

Specify an output resolution for rasterized artwork (except for mesh objects). In most 

cases, 300 is sufficient. The path output resolution affects the precision of intersections 
when flattening. (See 

.)

Select Convert All Text to Outlines to ensure that the width of text stays consistent 

during flattening. Enabling this option, however, will cause small fonts to appear 
slightly thicker.

Select Convert All Strokes to Outlines Strokes to ensure that the width of strokes stays 

consistent during flattening. Enabling this option, however, will cause thin strokes to 
appear slightly thicker.

Select Clip Complex Regions to ensure that the boundaries between vector artwork 

and rasterized artwork fall along object paths. Selecting this option reduces stitching 
artifacts that result when part of an object is flattened while another part of the object 
remains in vector form. However, selecting this option may result in paths that are too 
complex for the printer to handle.

Select Preserve Overprints When Possible if you are printing separations and the 

document contains overprinted objects. Selecting this option generally preserves
