overprint for objects that are not involved in transparency and therefore improves
performance.
Important: Illustrator always flattens overprinted objects when printing a composite,
regardless of how you set the Preserve Overprint When Possible option.
3 If your artwork contains raster-based effects (effects applied using the Effect menu),
choose Effect > Rasterize > Document Raster Effects Settings. Select High (300ppi) for
Resolution, and click OK. (See

Changing the path output resolution
Curves in artwork are defined by the PostScript interpreter as small line segments;
and the smaller the line segments, the more accurate the curve. However, when small line
segments are used to draw a curve, the total number of line segments increases, thereby
increasing the complexity of the curve. If a curve is too complex for a PostScript interpreter
to rasterize, a PostScript error can result, and the curve won't print.
The output resolution determines the flatness of the curve: A lower output resolution
results in greater flatness, and thus longer and fewer line segments. Using a lower output
resolution creates a less accurate curve, but improves printing performance.
Adobe Illustrator prints fastest and best by using a default output resolution setting of 800
dots per inch (dpi). However, in some cases, you might want to decrease the output
resolution—for example, if you draw a very long curved path that won't print due to a
limit-check error, if printing is slow, or if objects are not being printed at an adequate
resolution. To avoid or correct the limit-check error, you can split long paths, as described
in "Splitting paths to print large, complex shapes" on page
resolution for the document to a lower value.
To change the output resolution:
1 Choose File > Document Setup, and choose Printing and Export from the pop-up menu
at the top of the dialog box.
2 Enter a value in the Output Resolution text box. Recommended values are between
100 dpi and 300 dpi for printing at 300 dpi, and between 800 and 2400 dpi for printing at
2400 dpi. The limits are 100 and 9600 dpi.
3 Click OK.
Printing gradients, mesh objects, and color blends
Files with gradients, gradient mesh objects, or color blends can be difficult for some
printers to print smoothly (without discrete bands of color) or at all. There are ways to
improve the printed results of gradients, mesh objects, and color blends on such printers.
You can also improve the way that transparencies are printed.
Follow these general guidelines:
Use a blend that changes at least 50% between two or more process color components.
