Questions & Answers

Q: What is PDF for?

PDF is designed for exchanging documents through a general, high-quality format. It addresses problems caused by different software versions, Mac and PC systems, and people who prefer programs other than Microsoft Word.

Q: Why use PDF instead of sending Word files?

Word files could look different when opened with another version or on a different platform, such as Macintosh instead of PC. PDF provided a standard interchange route that was not tied to everyone using the same word-processing setup.

Q: Why is PDF useful for newspapers?

Newspapers need accurate documents that can print on enormous sheets while also being previewed at smaller sizes. PDF lets one document move between different sizes and resolutions while maintaining its quality.

Q: Why do engineers value PDF?

Engineers value PDF because its sophisticated, scalable graphics model preserves smooth shapes when drawings are enlarged. The speaker specifically describes PDF as useful for AutoCAD output, including architectural drawings and electronic circuit diagrams.

Q: Does a PDF lose quality when enlarged?

PDF is designed to preserve the quality of its scalable graphics as they are enlarged. A smooth circle should remain a smooth circle rather than breaking into dots, even when scaled to a much larger size.

Q: Why did Adobe make Acrobat Reader free?

Adobe concluded that people needed a reader to adopt PDF and that the reader had to be free. Charging for it would cause people to reject the format rather than use it.

Q: Was PDF successful immediately?

No, PDF was described as a long, uphill struggle rather than an overnight success. This contrasted with PostScript, which people were eager to buy from its launch in 1985.

Q: How much had Adobe spent on PDF during its early adoption struggle?

John Warnock told the speaker that Adobe had already spent $100 million on PDF. Despite the difficult adoption process, Adobe remained convinced that the format was the right solution.
