Finding ligature text in PDF when produced from InDesign CS5

Apr 16, 2012 5:31 AM

Hi everybody,

 

Can you please any one help me on the below issue.

 

When searching the PDF, some words are not found. If I search the word "final", I find 19 occurences of the word "finally", but none whatsoever of "final". The word "final" is only found if I search for "fi nal" with a space between the "i" and "n". I previously suspected a ligature problem. Please provide me a solution and it will be greatly appreciated.

 

Regards,

Sathishkumar K

    I remember this problem from years ago when generating PDFs with Distiller instead of by direct export from ID.  If direct export doesn't cure it then I'd wonder about the fonts and the foibles of glyph names -- which shouldn't be a problem with modern fonts.

    ligatures....ewww.

     

    Years ago I learnt a hard lesson about ligatures. They don't alway print as you see on your screen... funny characters can appear.

    What I I do is... always turn off ligatures... as a matter of fact, I unselect it as a preference so I don't ever have to worry about it.

     

    How about trying this... convert your PDF to postscript and run it through distiller again.

    In the last ten years the only time I can recall seeing ligatures substitute or drop out in print is when the font is not properly embedded in a PDF or downloaded to the RIP when printing direct from the application. Used to be more of a problem when working cross-platform with non-unicode fonts, though.

     

    I'm surprised that the ligature in final would be a problem, but not in finally, so I don't think it's a ligature issue, per se, but I don't know what the problem really is. Seems sort of like how type is sometimes broken up when you open a PDF in Illustrator...

    I must admit Peter... its been OVER 10 years since I came across the liguature issue... I've avoided them ever since.

    These problems are difficult, and details matter a lot.

     

    EXACTLY how are you generating the PDF, and exactly what tools are you using to view and search it?

    What versions of the tools, and what version numbers of the operating systems?

     

    Can you share the files with us?

     

    Lilia, I don't think it's fair to spread Fear, Uncertainty, and Doubt (FUD) about ligatures. They're an important typographical element that works well for many people. If there's a problem with it, we should figure it out and get it fixed rather than ignoring it and pushing it on to the next generation.

    thaj,

     

    Is the type formatted in InDesign such that there is a consistent difference between the instances of "final" and "finally"?

     

    If type is tracked out more than positive 20 or tracked in more than 60 units, the ligatures are broken (the letters are converted back to single letters).
