Preview Issue with PDF

I tried to view the document http://www.laser.org.uk/docs/uploaded/Clubssigned_up_for_2010AyL.pdf and the default viewer (Preview) shows just shows blocks where their should be text. However Adobe Reader (which I hate) shows the document fine. I cannot find any settings relevant that I have nt tried in Preview and cannot find anywhere to report it to Apple as a bug.

Anybody any ideas ?

I definitely have Calibri - came with Office for Mac and is the font I have set my "normal" style to use (plus my default e-mail font, etc.). I have checked in FontBook and Calibri is there, no duplicate fonts and I validated the font and it is all fine (regular, italic, bold, bold italic). My Calibri works fine in PDF's because I create a fair number of documents in Word (for Mac) and "print" them to PDF and Calibri is the main font I use.

What is weird is that the document has the font embedded anyway (at least the subset it needs), yet when Adobe Reader displays the document the fonts look nothing like Calibri.

I can open the file fine in Photoshop - but as with Reader, the font it uses is not Calibri.

Also, Preview done snot see the "blocks" where the text should be as text - as I cannot select them with the text cursor but only with the select (image/rectangle) tool. I can't see a way to attach an image to a port here but the blocks I get a like lines of giant black pixels (rectangles the size of a character) where the text should be, some fully black, then fading to lighter greys across the word (some starting black, fading to light grey, others starting light grey building to black, a few all solid black). Sorry for the lousy description.

I have double checked a PDF I created (using Word/Office for Mac) and it had two embedded subset fonts, Calibri and Calibri bold and it displays fine in both Preview and Reader and the font is very different from that Reader/Photoshop show for the problem document. Although in my document the "encoding" was set to "built-in" whilst the problem document has encoding set to "ansi"

Many thanks for your attention to my question.

Regards
Ian

I tried your PDF file. It opened right away in Preview.


Interesting. Do you have Adobe Acrobat installed? I also get the gibberish blocks with this document. This is identical to this previous thread from a few months ago.

In both cases, the PDF Producer is listed as "Microsoft® Office Word 2007". The only way that program is going to produce PDF is with Distiller. I think it is just a new format of PDF that Adobe is creating. That helps drive usage of Acrobat when only Acrobat can view the document.

Still, Preview should be able to display this document. I filed a bug with Apple against preview and Apple closed my bug as a duplicate. So, they appear to be working on it.

There are many posts on font problems with Preview, ever since 10.6.


It is not a problem with Preview per se. Any application that uses the MacOS X build-in PDF support has trouble with this document. The only applications I have that can open it are Photoshop Elements and Inkscape. Interestingly, Inkscape can convert the text in a PDF to text objects. (Elements can't do that). That feature fails with these files. Instead, it imports the text as paths.

Apple needs to support these documents better than with just some blurry blocks. I'm convinced it is just a new variation of PDF that Adobe has come up with that Apple doesn't yet support. There is another one that is a bit more clever, instead of the PDF content it just displays an ad for Acrobat Reader.

The interesting thing is why you are able to open this document in Preview. I keep my machines very clean and none of mine can open this document. My guess is that you have something a bit better than my Photoshop Elements that has wormed its way into your OS. I would get rid of Elements if I could, but nothing else is comparable.

I do have Adobe Reader (free) installed and it can open the document but the font it uses is defiantly not Calibri (as listed as the embedded font in the "problem document").

I also have Photoshop CS3 installed and that opens the document same as Reader (i.e. using the "wrong font").

Interesting comment about the Mac PDF support (as I am unaware of where the interpretation of the PDF takes place under OS X). I had also noticed that Finder preview and Quick view also show the same as Preview (i.e. blocks rather than characters).

A good way to drive people away from PDF. They sort of remind everybody that it is not an open standard but owned and under the control of Adobe and Adobe intend to make as much profit from it as possible. Given its extensive use (particularly in business), start sending PDFs to a customer who can only see an ad for Acrobat Reader and people will soon start finding alternatives.

Perhaps I was jumping the gun and getting a little too paranoid. Perhaps in this case, it isn't a new type of PDF that Adobe is trying to force on the world but rather a simple Adobe and/or Windows bug.

Okay, this isn't the problem I thought it was (which was a font cache problem in OS X), but one I have often run into when dealing with Adobe. If you create a PDF from files in recent versions of Word/windows with certain security settings enabled (at least I think that's the problem based on how they were able to fix it in later pdfs), the file is not readable on a mac (sometimes will work with Reader, sometimes not even then).

I don't think there is anything much you can do to make this legible, unfortunately.
