Saving PostScript-compatible files as binary

and ASCII

When saving a document as a PostScript-compatible file, you

have the option of encoding the file as binary (default) or

ASCII data. Save the file as a binary file to reduce the quantity

of data. Use ASCII if you plan to later edit the document.

To encode a PostScript-compatible file, first select Print to File

in the Print dialog box. Then choose the General menu of the

Options dialog box and select the Encoding option.

Using precision

bitmaps

To improve the quality of bitmap images, turn on the Precision

Bitmap option. This option is accessible from the Visual Effects

menu in the Options dialog box and slightly modifies bitmaps

for printing to a PostScript or PostScript-compatible printer.

Images are displayed on a Macintosh at 72 dpi; however, most

PostScript and PostScript-compatible printers print images in

multiples of 75 dpi. When 72-dpi screen data is converted to

print data, some image quality can be lost. If you select

Precision Bitmaps, the screen data is first converted to a

multiple of 75 and then printed, preserving the quality of the

image, though reducing the image size by approximately 4%.

Using the

MicroGray feature

The Dot Screen option of the Options dialog box allows you to

change the grayscale technology used by the printer to create

images. The options are Printer’s Default, Standard, and

Multigray/Microgray.

Normally you should use MicroGray for the best looking

grayscale images. Standard sets the printer’s grayscale

handling to be the same as the standard PostScript.
