Images on a page

Image data representing characters cannot be accessed as extracted text on the microfilm device. Data used in text extraction processing must be defined by code point.

Carefully consider the shading patterns used in the job. Jobs printed on paper can use much finer gradations of shading than jobs printed on microfilm. For microfilm jobs, IBM® recommends that jobs use only three shading patterns: none, 15% for 50% shading, and 30% to 100% for 100% shading.

Complicated images that use different gray levels might not print on microfilm with the same quality as on paper. This quality consideration applies to logos created as bitmaps (raster images) or with graphic drawing orders.
