Adobe has posted a version of the ISO 32000-1 document on its web site and it is freely available. Строительство домов
A friend of mine from various PDF conferences wrote me to ask me the following question:
Enclosed is a file that looks great, but the text can't be searched (or copied). Is there a tool that can automatically detect that all/most of the text in a PDF file can be searched (or not)?
In response to my previous post, a long time friend and collegue (Claudia McCue of Practicalia - one of the best trainers I know) wrote to ask:
Thanks for passing this on, but it looks to me like the Crop Tool still just masks out content: prepress wants a REAL crop tool that destructively gets rid of extra content. Some pagination software ignores the Crop info and just looks at the “real” dimensions. I’ll keep looking to see if I’ve missed something, though.
Claudia - I am happy to report that Acrobat 9 answers your needs! In fact, we provide two different ways to accomplish the task, depending on your particular workflow.
The best way to remove hidden information from a PDF - be it cropped data, unwanted metadata or other things that might be lurking about in your documents is the Examine Document command that was introduced in Acrobat 8.
In Acrobat 9, we have significantly improved this tool with more tests for hidden data, and an interactive display of the content to be removed so you can better pick and choose what stays and what goes. Oh - and you can incorporate this into a Batch Sequence, if you want to do this to multiple PDFs.
Alternatively, for those who are more familiar with, or spend their time working with our Preflight tools - you'll find two new Quick Fixes already provided for removing either information outside the CropBox or outside of Trim (more common in the print production world).
Of course, if neither of those suits your exact needs - you can create your own fixup which deletes content from the area of your choice. And don't forget that Preflight can also be called from a Batch Sequence or you can use the Droplets feature.
So Claudia - I hope that answers your questions and that you (and others) will find these new features helpful in your print production needs! (P.S. In exchange, you buy the beer next time ;)
One of the Acrobat engineers just shared with me a very useful feature that he put into Acrobat 9 to help out folks doing print production
with Acrobat. I thought I'd share it here.
Acrobat has had a Crop Tool since (at least) version 5, but that tool only let you set the CropBox of the page. While useful for non-printing features, most printers didn't like it because it only dealt with cropping while they deal with Bleed and Trim. They could have used Acrobat's Crop Pages dialog, but that requires you to type in values, and not work interactively and directly on the page.
Well not anymore!
Acrobat 9's Crop Tool lets you set the newly drawn out area as the ArtBox, TrimBox, BleedBox or (of course) CropBox. Just right-click (or control-click on a single button mouse) and at the top of the contextual menu are your choice of page boxes.
And with Acrobat 9 automatically showing the Art, Bleed and Trim boxes on the page, the result of your action is immediately visible.
As I've mentioned before, I've had two major projects during 2007 and 2008 - Acrobat 9, which is now shipping, and my work on the transitioning of PDF from Adobe to ISO, which I've spoken about as well.
However, while ISO 32000 (part 1) was ratified in January, the standard itself wasn't actually published until yesterday. But now you can run out, and for just a few Swiss Francs, get your own personalized copy of ISO 32000-1.
AIIM secretary, Betsy Fanning, writes in her blog:
While the committee's initial work has been completed in getting the standard through the approval and pubication process, the committee's work is far from over. The focus for the committee will now be to identify new features and functions that may be added to the PDF file and included in the standard. To follow the activities of the US committee for this standard, please visit http://www.aiim.org/Standards/article.aspx?ID=33223.
The committee is already at work on part 2 (or PDF 2.0, if you will), with our next meeting taking place in Beijing in October. I look forward to seeing the first (of potentially many) submissions from others on what they've always wanted to see in PDF but have not had the chance to suggest before. But now it really is "Everyone's PDF".
It''s already been reported all over the Internet already, but I wanted to also put a comment up here about their availability, since it's been a huge part of my life for the last 18+ months. It is also the first full version of Acrobat that I've helped design & develop, and most certainly the largest piece of software that I've been involved with in my more than 20 years in the software industry.
Here are some links and places to go, if you've not already done so:
Also, Lori posted some excellent sample PDFs that demonstrate the new Portfolio and Flash integration - if you'd like to see the difference these features make to the PDF experience - and why Acrobat 9 is such a "game changer"!
My colleague Joel Geraci, Adobe's Acrobat Technical Evangelist, just posted an excellent blog entry about the new Enhanced Security model and Privileged Locations from Acrobat 9. It's extremely important reading for anyone working with interactive PDFs.
Quoted from http://blogs.adobe.com/pdfitmatters/:
Enhanced Security: Privileged Locations
Security is often at odds with usability. Adobe Flash began addressing this problem several releases ago by implementing and standardizing on a cross-domain security model that has evolved over the years into a robust, secure solution. By providing controls for who may receive data from whom, Adobe Flash can power rich Internet applications that are safe and extremely flexible.
An excellent explanation of the cross-domain security model can be found here

As I mentioned in an earlier posting, Acrobat 9 introduces support for the Ghent PDF Workgroup's recently published Proof of Preflight specification, the details of which can be downloaded from here.
In brief, this specification provides a way for any preflight vendor to identify PDFs that have already been processed, and the result of that processing - whether it be success, failure or only a warning. The preflight vendor also clearly details the information about their product (name, version, etc.) as well as the profile used in the processing. On the left is an example of the Preflight Audit Trail section of the Standards Panel that will appear when you open a file that has an Audit Trail added (in all versions of Acrobat and Reader). In addition to seeing the information about the preflighting that has been done, you can also verify that the profile used matches the one on your computer - so as to ensure that the user hasn't tampered with your profile in any way!
![]()
Finally, the file is "locked down" (via a standard PDF Digital Signature) so that it is quite clear whether it has been modified since the preflight operation has taken place. This prevents the file from being modified and possibly breaking the Audit Trail. However, should you need to perform late stage editing, you can remove the Audit Trail via the link in the panel.
![]()
Acrobat 9 Pro and Pro Extended users, after completing the execution of a Preflight Profile or Quick Check just need to click the "Embed Audit Trail..." button at the bottom of the Preflight window in order to have the Audit Trail added to the document. Even if the file didn't completely pass the profile - the Audit Trail can still be useful to convey that information as well.
According to the Desktop Publishing glossary of terms, Overprinting is defined as:
Definition: In most cases, when two objects of different colors overlap they knockout -- they won't print on top of each other. To intentionally print one layer of ink on top of another is to overprint. Overprinting is sometimes used to avoid the need for trapping and avoid gaps between touching colors. Spot colors intended to designate the application of spot varnish are also set up to overprint.
But if you ask me - it's just the biggest pain in the printing industry's derriere.
The reason that it is such a nightmare for designers is that the act of overprinting only makes sense on high end printing devices - it doesn't make sense on a computer screen or the average home/office printer. As such, for the longest time, designers had to print to see if they were doing their design correctly. Fortunately, Adobe introduced "Overprint Preview" into Acrobat and our authoring applications so that you could see what going on, on screen, while authoring and with the finished PDF.
Unfortunately, for the longest time, only Acrobat itself could preview Overprint. It wasn't until Reader 7 that the feature was added to Adobe Reader - and then, like Acrobat, the option/preference was OFF by default. Designers, printers and the like had to make sure that they had their preferences set correctly and provide their users with proper instruction.
With Acrobat 9, we decided that enough is enough! Designers need to know that users, whether they are using Acrobat or Reader, regardless of their preferences, see what is going to print. Isn't that a big reason why people use PDF??
In designing this feature, we originally planned for it to just be completely automatic and appear only when a PDF had the necessary components. However, we discovered that there are many files out in the world that weren't really supposed to be printed, and thus generate a "false positive" and produce inaccurate renderings. What is worse, is that 99% of these "false positives" are PDFs authored using a well known competitor to Adobe's products - and we didn't want to be seen as "playing favorites" with the quality of document rendering.

So we did the next best thing! We went looking for a clue in PDF documents that demonstrates that they are - without a shadow of a doubt - destined for printing. That "clue" is compliance with PDF/X (ISO 15930)! Since PDF/X is a standard designed for the creation of PDFs for blind exchange in print production - we can clearly say that all such files SHALL have Overprint Preview enabled. And that's exactly what Acrobat/Reader 9 does. As part of it's PDF/X Conforming Viewer implementation, when it detects that a PDF is compliant with PDF/X - it makes sure that overprint is properly rendered to screen.
We did, however, leave the preference in place - so that if you really want to turn Overprint Preview to "Always" or "Never", you are welcome to do so. We also left in that original "Automatic" option for anyone wanting to experiment and see the results.
Everyone in the print/publishing community that I've talked to is really excited about this feature...I hope you will be too!
PDF 1.4 introduced Reference XObjects, but it has not been implemented in Acrobat in the intervening years. With the growing popularity of PDF/X-5g documents and interest in variable data printing (VDP), the Acrobat team decided to add support for Reference XObjects in 9.0.
