This property controls the number of digits placed after the decimal point in coordinates written to the PDF file. Higher precision improves print quality, especially for TrueType text, at the expense of larger PDF file sizes.

The default precision, Standard, is designed to produce the smallest PDF file size with good text quality at printer resolution. PDF coordinates are rounded to 1/10th of a point. At high zoom levels in a PDF viewer, text may appear slightly deformed.

If the precision is set to Improved, text coordinates are rounded to 1/100th of a point while other coordinates are rounded to 1/10th of a point. This setting is designed to balance text quality at high zoom levels with PDF file size. PDF file sizes may be between 10-25% larger than when using Standard precision.

If the precision is set to High, all coordinates are rounded to 1/100th of a point. PDF file sizes may be between 20-50% larger than when using Standard precision.

If the precision is set to Maximum, no coordinates are rounded. PDF file sizes may be between 30-80% larger than when using Standard precision.
