Over at the Economist, our own Glenn Fleishman has discovered why certain Xerox copiers were mixing up numbers on copies. The culprit turns out to be the JBIG2 compression algorithm, which is not enabled by default, and copiers display a clear warning if it is enabled. JBIG2 is a form of ultra-high compression that duplicates similar-looking areas. It’s popular among businesses with extreme bandwidth requirements, such as remote oil rigs, but should not be enabled unless absolutely necessary. Xerox is working on a patch that will allow system administrators to disable the feature entirely. follow link
Find Text Leading from Acrobat PDF
Ever have to recreate a document from an Acrobat PDF? You can find out most everything about the text by using the Object Inspector, except the leading. Well, here's a cheesy way to figure it out. Open the PDF in Illustrator (you just need one page). Release any and all clipping masks. Draw a guide at the baseline of the first line of text, and one on the line below. Now, Option-drag the first line to make a copy, and position it exactly next to the original first line at baseline. Then put a return anywhere in the copied line. Now adjust leading of the copied lines, so that the second line of copy rests on the baseline of the second line of the original. Now you know your leading.
Or you could buy expensive software to find the leading. Your choice.
