PDF Multi-Resolution Image - Enhanced PDF Image conversion

The Enhanced PDF Image or the Multi-Resolution PDF Image files combine monochrome (black and white) text zones with 24-bit color or grayscale images for photographs and diagrams. Both monochrome and color/grayscale images are represented on the same page for the best-possible replication of the paper original. This process delivers optimum readability and image quality at a far smaller file-size than any competing technique.

 Typical applications include: -

• Smaller files -Most imaging bureaus deliver color by the page, not the image. Full-page color scans mean huge files and, often, inferior resolution and image quality due to the sacrifices made to keep the file size down.
  
  
• Superior text quality. Since the text area of the image is rendered in higher resolutions and with lossless compression, on-screen and printed text quality is vastly superior in Multi-Resolution files.

 

 Typical applications for this format include documents requiring total graphical fidelity to the paper original while maintaining low file size.

• Low-cost electronic publishing of legacy/historical materials
• Advertising and promotional materials
• Academic journals and research material

	Image	Image + Searchable Text	PDF Normal (Formatted Text & Graphics)
Accuracy	Very high  (Page is retained as image)	Very high (Page is retained as image)	High (in effect, re-authoring the document)
Text searchability	No	Yes	Yes
File size	Large  (Typically, 40-50 KB at 300 dpi without grayscale or color images)	Large  (Typically, 50-60 KB at 300 dpi without grayscale or color images)	Small size (Typically, 4–6 kb per page for simple documents)
Typical Application	Budget friendly archiving	Full-text search for bitonal files	Tiny but rich files - great for the web
