Using Publisher PDFsUsing Publisher PDFs

Sometimes students can use files directly

Often files will need further processing for student use

At the very least, large files may need to be broken into chapters

PDF StrengthsPDF Strengths

Good format for large print Cropping Fit to page on large pages Print sections on large pages (tiling)

Adobe Reader has some nice features Change colors Reflow Limited voicing

Works on both Mac and PC Easy for most publishers to create

PDF WeaknessesPDF Weaknesses

Not always fully accessible Screen readers do not always like them—

even when they are text-based Reading order can be problematic

May be graphics (pictures of text) May have too much security

As an Aside…As an Aside…

When faculty create PDFs… The PDF always started as something

else…usually a Word file Try to get the starting document if the

student prefers audio Security concerns?

Word files can be password protected Button > Prepare > Encrypt

Types of PDF DocumentsTypes of PDF Documents

Better Text Extraction

OCR programs analyze text and structure Acrobat Pro has built-in OCR, but other

programs provide more control Can control which text to include

More Control over Text

For graphical PDFs Or To maintain more control over extracting

text from text-based PDFs Use an OCR program!

Processing Graphical PDFsProcessing Graphical PDFs

Must run optical character recognition (OCR) Computers cannot read pictures OCR programs recognize the “characters” in the

picture

How you process the file depends on the end format the student wants!

Want to Stay in PDF?

Sometimes students do want a text-based PDF

Can OCR in Adobe Pro Tools> Recognize Text

Under Tools

Want Text OutWant Text Out

OmniPage or FineReader FineReader generally easier to learn Save to Word or HTML or Text based on student

preference

Use virtual printer with Kurzweil Create KESI files

R&W Save as Word

Which One When?Which One When?

Want a Word file? Best choice is OmniPage or FineReader

Want a Kurzweil document? Use Kurzweil to process the PDF

For students to do themselves? Whichever program they prefer

Why?Why?

OCR programs are designed to make extraction and editing easy

Document readers (R&W, Kurzweil, etc.) are designed to make reading easy…NOT editing.

NEVER!!!NEVER!!!

Do NOT run OCR with FineReader or OmniPage…save to PDF…and then take into Kurzweil, R&W, etc.

Kurzweil, R&W, WYNN will run their own OCR on the PDF! Wastes time, adds error to do OCR twice

OCR ProgramsOCR Programs

Treat PDFs the same as a TIFF If you OCR scanned documents, use the

same process

Load image file Select zones Create templates as needed

OCR Process Details

Crop before loading into OCR engine Turn on multiple languages as needed

If doing math, turn on Greek Only turn on the languages you need

Edit in the OCR program Some OCR programs have font matching features

Save to Word

Captions and Such

For students who want audio or who are using screen readers Separate the main body of the text and the

“ancillary text” (captions, sidebars, footnotes)

Create two documents 00 Chapter and 00A Chapter

Allows the student to hear main text uninterrupted

Two Doc Workflow

Open PDF in OCR Program Analyze layout for entire document

Save a copy On one copy…delete all ancillary text

Save to Word as 00 Chapter On other copy…delete all main body text

Save as 00A Chapter Keep page numbers in both documents!

Once in Word

Beware of the optional hyphen Search and replace to delete Search for ^- replace with nothing Run spell check

Use styles to structure files for braille program
