Instructions provided describe how to modify the dots per inch (dpi) or output resolution from ArcMap default when printing or exporting at a higher or lower resolution.

• JPEGs and TIFFs exported from ArcMap are always 72 dpi
  An image exported to JPEG or TIFF is always 72 dpi, regardless of the resolution set in the Export Options Dialog. However, the size of the image changes proportionally with changes to the resolution. For example, a 2" x 4" layout at 300 dpi actua...
• DibExporter does not support IExporter::Resolution property
  If the ArcMap IExporter object is created and set as a DibExporter, Visual Basic returns an error when the user attempts to set the IExporter::Resolution property.

The Output Image Quality (OIQ) option allows the amount of raster resampling that occurs when a map is printed or exported to be controlled.

This resampling affects any raster data, transparent map layers, and picture fill symbols.

Increasing OIQ towards 'Best' improves the quality of the output image but can also significantly increase file size and printing time.

Decreasing OIQ towards 'Fast' decreases files sizes and printing times, but with a proportional degradation of the image quality.

The setting between 'Normal' and 'Best' is a good compromise solution. This setting combines good output quality with manageable file sizes and acceptable printing and exporting times.

Instructions provided describe how to use the Output Image Quality (OIQ) option. The OIQ option is available on the Page Setup dialog box in ArcMap 8.x versions, but was removed from Page Setup and added separately to both the Print and Export Map dialog boxes for version 9.x and above.

• ArcMap 9.x and above
  1. When printing, click File/Print.
  
  When exporting, click File/Export. Click the Options triangle to expand the Export Options panel if it is not already visible.
  
  2. Move the Output Image Quality slider left or right to increase or decrease the output image quality, or type a 1 into the x value in the edit box. For example, 1:1 equates to Best mode or no change.

  The Output Image Quality setting is only available for the five vector export formats: EMF, PDF, EPS, AI, and SVG. For raster export formats, OIQ always exports with a setting equivalent to Best. For those formats, the resolution setting can be decreased to create smaller export files.
• ArcMap 8.x
  1. Click File/Page Setup.
  
  2. Move the Output Image Quality slider left or right to increase or decrease the output image quality.
  
  For ArcMap versions 8.1 through 8.3, the slider snaps to the tic marks.
  -show me-
  
  For ArcMap versions 8.0.1 and 8.0.2, the slider is continuous.
