How To: Use the Output Image Quality option

Summary

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.

Procedure

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.
      The Output Image Quality (OIQ) option is available on the Page Setup dialog box (File > Page Setup).
      
      The look and feel of this option in ArcMap 8.0.1 and 8.0.2 is slightly different than in ArcMap 8.1 (see below), but its usage is identical.

      For ArcMap versions 8.0.1 and 8.0.2, the slider is continuous.
