In outputting an Extended Family chart to Adobe Acrobat, there seems to be a limit of 200" in width even though I have Acrobat set to Oversize page and have specified a page size of 300" x 20" which should allow the poster to be output on a single page. Acrobat has a limit for Oversize pages of 15,000,000" x 15,000,000" so I suspect that FTM2012 has the 200" limit. Adobe increased to limit from 200" to 15,000,000" with version 6 of Acrobat and they are on version 11 now.
Is this correct that FTM2012 has a limit? If so, is there a work-around other than outputting to multiple pages and then merging them in Photoshop?
