How to reliably check the resolution for a pdf file?

Mar 21, 2012 11:14 AM

Should I use preflight to reliably check the resolution for a pdf file?  I have posted my frustrations on http://forums.adobe.com/thread/978098

    Hi Hannah,

     

    I believe Preflight is all you'll need. Going by the example you gave it would seem that there's an error in the conversion of the resolution for output. Are any particular errors displaying?

    What do you use in preflight to check the resolution?  I need to know the dpi not the ppi.

    You can create your own preflight tool to check for the dpi of embedded images.2013-07-16_11-37-38.png

    For "digital" it is "PPI" (pixels per inch). For the umbiquitous imprints to paper via printers it is "DPI" (dots per inch) - from back in the day when attached printers were line printers and dot-matrix printers.  As you dealing with "digital" (a PDF) "PPI" is appropriate.

     

    Be well...
