Studies

Searchable PDF - OCR Recognition Accuracy: Searchable PDF can be made made by multiple applications using different OCR engines. Different OCR engines will produce different levels of text recognition accuracy, as we demonstrate.
Latest Digital Document Formats for Scanned Manuscripts: Scanned Manuscripts need to be in color, which makes for big files that are challenging to compress sufficiently for web delivery, but  the latest digital document compression methods in PDF and DjVu are up to the challenge.
Presentation of New Adobe Acrobat 6 Compression Methods: Acrobat 6 is now released and so is the PDF 1.5 format upgrade, supporting JPEG2000 compression. Presented here are test files using the new compression methods of the PDF 1.5 format, and  a comparision to the DjVu format.
Optimizing Prepress PDF for Size: JRA is pleased to represent a new compression product for Mac-produced Prepress PDF, and other digitally-produced PDF files, called Sage pdfEnhancer.  Presented here are the compression results for a set of newspaper pages and for 4 complete newspaper issues.  The size is reduced by 31% - 43%.
Comparison of Advanced Compression for Bitonal Images: JBIG2-PDF and DjVu offer both advanced compresssion AND a searchable text-layer. This study extends the example tables for JBIG2-compressed PDF at both the Adobe and CVision websites, and then also adds a study of typical technical papers, for a complete roundup of searchable-image files supporting token compression.
Presentation of scanned Clippings in PDF and DjVu: Newspaper clippings can be scanned, OCRed, sized, matted, compressed and then seached on the web, in PDF or DjVu formats.
Named Destinations for Newspaper Digital Tear Sheets: Named Destinations in PDF filess can both be used by newspaper publishers to create digital "tear-sheets" for advertisers.  The Named Destinations take the advertiser directly to a view of the ad where it is placed on the page.
Broadsize Newspaper Comparison: Broadsize newspapers can be scanned and OCRed for web-searching, but care must be taken to prepare areas with shaded backgrounds for OCR.
National Textile Center Article Thread Study: Article Threads can double as Named Destinations and then be directly opened from a web brower link.
ME-CE PDF Examples and Application Support: ME-CE is the support for Middle Eastern and Central Eastern versions of Acrobat and Acrobat PDF, which add suport for those non-latin languages which are used in the Middle and Central European Areas, and which must be supported with Unicode and Unicode-enabled applications.
