  • 'Font contains bad/Widths' and 'Cannot find/create font' errors when saving pdf as Other Reduced Size PDF

    I am exporting .indd files from within Indesign as pdf files, opening in Acrobat Pro XI. I have no trouble creating the initial pdf file, however, when I go to Save Other > Reduced Size PDF I get error messages. Depending on the file, I receive either the message, "The font (Myriad Pro) contains bad/Widths" replacing the text with dots or "Cannot find or create the font (Helvetica) Some characters may not print or display properly" replacing text with dots or boxes.
    My confusion is that the file is exporting to pdf from Indesign without error, it is only when I try to Save Other> Reduce Size PDF that the error occurs.
    Also, it is only occurring on five out of 120 pages. These same fonts are on other pages and I have no trouble at all with exporting or Reduce Size PDF.
    More frustrating is that I have never had this problem occur in all my previous versions of Acrobat using the same process and typefaces.
    I am reaching deadline on this and cannot find a solution other than to reload Acrobat 9 and ditch this upgrade.
    Any help would be greatly appreciated.

    I, too have experienced this issue. Upon export from INDD CS6, I see the error message "The font 'IXWIPX+SourceHanSansSC-Bold' contains bad \Widths."
    The only items on the single-page InDesign document I'm trying to export are copies of a one-page PDF (which was extracted from a longer PDF, arranged into a cover format). I can provide all files as necessary. The longer document that the one page came from also experienced an error when I tried to print to Adobe PDF. While I still get a PDF of the cover on export, despite the "bad \widths" message, it won't print from certain machines. I get nothing (not even an empty shell file) from the attempt to print the larger document (where the cover elements came from) to PDF.
    I can deal with these issues with a few unorthodox workarounds, but wanted to offer comments or volunteer to help test fixes if possible.
    For the record, I'm really not enjoying Acrobat XI. It doesn't seem to have much by way of new features (at least not that I use), and some of those I used most in version X are gone or less functional. Common fonts like Times New Roman are often not found (even though they are definitely on my system); I have a much harder time editing text through the new interface, and I have a few other small gripes—some that I don't have time to get into, others that wouldn't really matter, except that they weren't a problem until I "upgraded." Just sayin'.
    Thanks for listening.

  • Acrobat 10.1.8 not responding Save as Adobe PDF and reduced size

    Your comment all software is up to date is wrong.
    Unless You using a PowerPC Machine  OSX up to 9.1
    Acrobat X may be at 10.1.8  but the newest available is Acrobat 11.0.4
    And what seriously out of date and may be causing your issues is That Office2011 is up 14.3.9 By using out of date application may cause part of your issues. Note it does take a Long time to process a Large document
    If you can get the PDF to open
    Look for and Choose Optimized PDF or PDF Optimzer
    click fonts if you see any duplicate Fonts
    example two or three copies or more of say Helvetica Bold Italic
    click on all but one of them and move to unembed
    Repeat with all Fonts that have duplicates.
    Then click okay when done.
    This issue can be caused by older versions of software.
    But if downloaded from a PC the number one reason is that unlike Mac in which your old allowed one copy of a Font/Font Family. PC doesn't care how many copies fonts there are on the computer. Whatever app just choose one to use at that moment. So you could have 20 versions of Helvetica bold Italic and the syetem doesn't care.
    I've received PDF from PDF's from PC's and there have been as many as 10 copies of one font.  Once optimized the files size went down.

  • How to reduce size of C:\Windows\winsxs folder in windows 2008 R2?

    Hello,
    Is there any way to reduce size of C:\Windows\winsxs folder in windows 2008 R2
    simular to 
    DISM /online /Cleanup-Image /SpSuperseded
    Many thanks

    Okay maybe some background on the root of the problem would help.
    Windows XP (and Windows 2000) used a fast and great mechanism called Hotfix Installer (Update.exe) to install updates. Updates installed in very little time. If you wanted to further reduce update times on Windows XP, you could just temporarily stop the
    System Restore service and updates would install at crazy speeds. Note that this is not recommended for novice users who don't know advanced recovery methods, as some updates can sometimes cause your system to stop booting so you cannot even uninstall them.
    The method the Hotfix Installer used was simple, it just installed a new version of files to be updated at %windir%\system32 and %windir%\system32\dllcache (the Windows File Protection cache). For files that were in use, a restart copied them from dllcache
    to the system32 folder. This is simple file-based servicing. The hotfix installer (Update.exe) also supported various command line switches like /nobackup which means not to backup files it patches. Again, this is not recommended for novice users as some updates
    can screw your system even after the comprehensive testing Microsoft does before releasing them. But if you won't be uninstalling any updates (usually one only requires uninstalling updates if they cause problems), you could save a ton of disk space by not
    backing up the files it patched. The Hotfix Installer backed up files to C:\Windows\$Uninstall$KBxxxxxx folders so even if you did back up the files at install time, they could be safely deleted after a few days if no stability issues were found after using
    Windows with the newest updates applied. Update.exe also supported the very important and convenient ability to slipstream a service pack or update into the original Windows setup files using the /s switch.    
    When Microsoft was developing Windows Vista, they realized that components had gotten too many interdepencies on each other and to service each file reliably without breaking another component that relied on it, Microsoft introduced what they called as Component
    Based Servicing (CBS). You can read all about it in a much more technical way at The Servicing Guy's blog. What CBS does basically is it installs all files of the entire operating system, including all languages into C:\Windows\WinSxS and then it hard-links
    files from there to C:\Windows\system32. This has the benefit of not having to insert the OS disc to add or remove any components, and some other advantages as well like offline servicing of a Windows Vista or Windows 7 image. But the design introduces a major
    disadvantage of taking up a lot of hard disk space. Whenever an update is installed, it no longer installs it to C:\Windows\system32 and C:\Windows\system32\dllcache like Windows XP's hotfix installer (Update.exe) did. Instead, it updates the files in C:\Windows\WinSxS.
    Now, Windows keeps multiple copies of the same file but with different version in WinSxS if it is used by more than one Windows component. The higher the number of components, that many number of times the file exists in C:\Windows\WinSxS. When a Windows Vista
    update (.MSU) is installed, the components get updated, each and every one, instead of the files and the worst part is it still maintains the older superseded previous versions of components in WinSxS so the user would be able to uninstall updates. Microsoft
    does say that some sort of "scavenging" or deleting older copies of components takes place but is scarce on the details. The scavenging seems to take place automatically at certain intervals in Windows 7 but not in Windows Vista. In Windows Vista, you have
    to add or remove any Windows component for the scavenging to take place. And Microsoft says the scavenging will free up some disk space but in practice, on my system, I see my free disk space only decreasing on Vista as I remove or add any component. Windows
    does not give the user an option to not backup the earlier versions of components like Windows XP's /nobackup switch in Hotfix Installer did. As as you install more and more updates on your system, they will take more and more disk space. This is one of the
    primary reasons Windows Vista and Windows 7 are so bloated. Another reason for them being so bloated is the DriverStore that these OSes store. All drivers that are shipped with the OS and the OEM ones which you download and which are installed for a particular
    system are staged in C:\Windows\System32\DriverStore. But let's not go there for now.
    Now, an important thing to note is that the size of the WinSxS folder is not what Explorer or the dir command report, it is far less but is misreported by Explorer because it counts the hard links more than once when calculating size. That does not mean,
    the size of WinSxS is not causing real-world disk space problems on numerous Windows Vista/7 systems in use today. Microsoft's ingenious recommendation to this problem of ever growing disk consumption is to install fewer updates to keep the size of the servicing
    store under control. Of course, users cannot deny installing security updates and leave their system open to security holes. What they can do is install less optional updates, the ones that Microsoft releases on the fourth Tuesday of every month and also install
    less of the hotfixes that are available by request from a Knowledge Base article. In short, you have to trade the number of bugs fixed in the OS by installing hotfixes at the cost of enormous amounts of disk space. The whole servicing stack is a total downgrade
    to Windows XP's update.exe method. It causes heavy disk thrashing and slow logoffs/logons while Windows configures these updates at the Welcome Screen. Many systems are unable to boot because of failed updates. Another disadvantage of the "new" servicing stack
    (and the redesigned Setup mechanism of Windows Vista) is the inability to do a true slipstream of service packs and hotfixes.
    The time it takes to actually install these hotfixes online compared to Windows XP is also completely unacceptable. When you start installing an MSU update, it spends a lot of time determining whether the update applies to your system. Then, the update itself
    takes much longer to install compared to Windows XP's Update.exe (hours instead of minutes if you are installing dozens of updates through a script). Finally, that post-installation process ("Configuring updates... Do not turn off your computer") takes several
    minutes before shut down followed by a second post-installation process (configuration) upon restart before logon that also takes also several minutes and thrashes the disk.
    I can install the entire SP3 for Windows XP in about 10 minutes after downloading the full installer. I can also install a slipstreamed-with-SP3 copy of Windows XP is about 45 minutes on a modern fast PC. In contrast, Windows Vista or Windows 7 do install
    relatively quickly (in just about 15-20 minutes) on a modern PC but installing the service packs and updates takes more time than anything on XP did. Not only can service packs not be slipstreamed, but Vista Service Packs are not even cumulative, which means
    if you clean install Windows Vista today, you have to install SP1 first which takes about 90 minutes, then SP2 which takes less time, then all the post-SP2 updates which do take hours to install. If you really HAVE to use Windows 7 or Windows Vista, you are
    stuck with this slow update non-sense as Microsoft does not even acknowledge that there is any slowdown or loss of functionality in the new servicing mechanism. The fact remains: MSU updates are slow as **** and take too much time and as Windows 7/Vista get
    older and Microsoft stops producing service packs, a clean install is going to take longer and longer to bring it up-to-date with all patches installed. Is is worth wasting your time on an OS whose servicing mechanism Microsoft completely screwed up? I once
    again recommend you read more about the servicing stack and how it operates at The Servicing Guy's blog:http://blogs.technet.com/b/joscon/. To fix this messed up servicing stack, Microsoft also offers a tool
    called CheckSUR for your system if it finds “inconsistencies in the servicing store”.
    Microsoft's Windows Vista and Windows 7 products are not engineered with disk space in mind. It causes a problem, especially for SSDs which are still low capacity and very expensive. The only hope is that Microsoft again completely redesigns this servicing
    mechanism in a future Windows release so it would not cause this growing disk space consumption issue, speed up installation of updates by an order of magnitude, not slow down logon and logoff, not prevent systems becoming unusable because of failed updates
    being stuck at a particular stage and allow true slipstreaming.
    Microsoft's response to this is vague - they simply state "Windows 7's servicing is more reliable than Windows XP" but they cannot acknowledge it is a million times slower and still unreliable...slow to the point of being unusable and sometimes leaving systems
    in an unbootable damaged state. Of course they know all this too but can't admit it since it makes their latest OSes look poor. Moving from a very simple and fast update mechanism that worked to a complex one that requires endless “configuring” and repair
    through CheckSUR is a product engineering defect.
    Take a look at servicing-related complaints in Microsoft's own forums:
    1.
    Very slow install of updates to Windows 7
    2.
    Windows 7 - Updates are very slow
    3.

    4.

    5.

    6.
    Why does my computer run so slow when installing updates?
    7.

    12.

    13.

    14.
    Why can't windows 7 install updates?
    15.
    Every time computer is shut down, receive Installing updates, do not shut off....
    16.
    How long does it take for the Windows 7 Home Premium updates take?
    17.

    18.
    Updates causes endless reboots
    19.
    Updates stuck installing for over 24 hrs. Computer does not boot
    20.
    Cannot load Windows 7 after installing 2 critical updates
    A proper solution to this problem would be to completely re-engineer and rewrite the servicing mechanism so it operates with the speed, reliability and pain-free operation of the XP servicing mechanism.
    I don't see this situation improving in Windows 8 either. Good luck with your Windows tablet taking hours to install service packs and updates. Now, do iPads take that long to install updates?
    Microsoft understated the real system requirements to keep a Windows 7/Vista system running. System requirements at install time may be 15 GB of free disk space but over time, this number increases to alarming levels as you install more service packs and
    post SP-updates. You can find out the real size of the WinSxS folder using a tool like cttruesize (ctts.exe) (download it from
    http://www.heise.de/software/download/cttruesize/50272 and run ctts -la -a -l C:\Windows to find the correct size minus the hard links which MS says causes Explorer to misreport the WinSxS
    folder size but the fact remains that even with the correctly calculated size of WinSxS, the disk space requirements of Windows 7 to keep it updated are unacceptable, especially for people's SSDs which are running out of disk space!

  • Why does PDF Optimizer no longer reduce size after CS4 upgrade?

    I've been able to successfully reduce the size of the PDFs created from my Illustrator files for years using Advanced> PDF Optimizer in Acrobat Pro. Upgraded to CS4 last week. Now it seems to have reduced everything, but the files are still huge. When I check Space Audit 96% or more is taken up by "piece information".
    I've tried changing the Adobe PDF presets, the Document Raster Effects settings, and outlining all text in Illustrator to see if that made a difference. Nothing. The frustrating thing is i've done this for years with no problem. HELP?!?!

    Hi, I've found the solution because today it happened to me as well.
    Just go to "PDF Optimizer", then click to "Discard user data" and finally to
    "Discard private data from other applications": in this way you delete any
    information left by Illustrator and your file's size will get reduced.
    It works.
    Good luckThanks so much! That works like a charm!!

  • About save as reduced size pdf

    I noticed that saving as reduced size pdf shrinks a lot my pdf files.
    What does it do precisely? Is there a way, with Acrobat X or some other software, to do the same to a large collection of files in few steps?
    Any compatibility problem reading that kind o pdf on mobile devices (BlackBerry, Android, iPhone, WP6 or WP7)?
    Bye
    Dario

    don't think it's the right explanation: incremental updates are removed with a simple "save as" action.
    Infact, the size of my files (not modifyed after first creation), doesn't change if I open and do a simply "save as" them.
    Size will change with Save as > reduced size PDF... it must be doing also something else that regards the version compatibility: I noticed that setting an higher value in the box asking for Acrobat compatibility level will impact the final size of the file.
    Keeping actual level will save, on the test file I'm using, about 4 MB. Setting at 9.0 compat. level will obaint the 4 MB file. The quality of the output pdf is lower than the original, so it's also doing some kind of compression.
    An explanation could be: it does file compression using the best algorithm available for the version selected?
    PS
    Is there a way to get statistics on PDF files, like the space used for incremental updates?
    Bye,

  • Reducing size of PDF not working

    Does anyone know why when trying to reduce a PDF by selecting Save As then choosing Reduced Size PDF wouldn't work on certain documents.  I did several PDFs and it worked fine.
    I have a bunch more that are over 1 MB and are too big to be emailing so I need to make them smaller.  Some appeared to work but the size didn't change others I get a box that pops up with a Conversion Warning... An error was encountered while saving the document.
    Thanks

    Try File menu >Save As... > Otimized PDF
    When Optimizer open click Fonts Tab.
    See how many copies of each font style (Bold. Italic, Bold Itallic, etc) yu have.
    Remove all copies except one (example if you have 5-6 copies of Helvetica Italic which is frequently Possible) remove all copies except one.
    I seen cases in PDF I have created where had as many as 6-7 copies of the same font version in the same PDF and maybe multiple font versions  often reducing the size by as much as 75%. (Not usually But havehad  it happen.)
    Also click on the Tab for pictures unless you plan on printing a business report, 200dpi/ppi is the most you should use.
    Save as a slightly different version. Open new version and check the size.

  • Reduce size of Air runtime for mobile apps

    Flash & Air are fantastic for create Android apps
    but most of user don't have Air Runtime package on their phones and we must embed this in publish
    unfortunately the size of adobe air runtime is about 8 MB ! and with slow internet it take long time to download the apps , and even for getting this apps with Bluetooth
    is there any chance to reduce size of Adobe Air Runtime ?
    or create various version of Air runtime , for example in most project we don't need play video or sound ...

    This has been asked before several times. I doubt you will get a procedure from NI on how to do this since the run-time engine is intended to be a collection of libraries to be used by various types of LabVIEW apps.
    That said, it doesn mean that users haven't tried to figure out how to do it. Note: I do not recommend this practice nor can I speak to its effectiveness since I've never tried it.

  • Actual Size (Full Quality) photos being e-mailed at reduced sizes! Why?

    Yesterday I e-mailed six photos to a party in Nova Scotia. Because of the large file size of the photos--ranging from 6.7 MB to 9.2 MB--I opted to e-mail each photo individually. In iPhoto I chose the Actual Size (Full Quality) size setting for each photo.
    Imagine my surprise when I discovered that every photo was e-mailed at a reduced size. For example, the indicated attachment size for the 6.7 MB photo was only 4.6 MB, and for the 9.2 MB photo only 6.1 MB. This is the first time I have noticed photos being e-mailed at reduced sizes even when the Actual Size (Full Quality) size setting has been chosen.
    I would appreciate knowing what is going on here and what I need to do to remedy this situation.
    Bob

    Terence,
    The problem remains unresolved. I followed your recommended procedure and got the same bizarre result!
    I selected in iPhoto the same 9.2 MB photo I e-mailed to Nova Scotia yesterday, clicked on the Email icon, and selected Actual Size (Full Quality). The Mail 1 Photo window correctly showed the estimated size as 9.2 MB. I clicked on the Compose Message button which took me to the E-mail message window. I verified that the Image Size indicated at the lower right hand corner of the window was Actual Size. Interestingly enough, the Message Size indicated in the lower left hand corner of the window was 8.2 MB. Somehow my photo size was reduced 1 MB in the process of it being prepared for E-mail delivery! I then e-mailed the photo to myself. When I opened it up it showed 1 Attachment, 6.1 MB. This is the exact same result I got when I originally e-mailed this photo to Nova Scotia.
    My primary concern here is that the quality of these photos is likely being compromised by this size reduction phenomenon which I have not previously noticed. I'm wondering whether this is a problem with iPhoto '09, Version 8.1 (415) to which I just recently upgraded from iPhoto '06. For your information I have also long employed iPhoto Library Manager (Currently version 3.5.5).
    Perhaps you can try this same procedure and see if you get the same goofy result. I'll be eagerly awaiting your reply and advice on how to resolve this issue.
    Bob

  • Can you send an email with multiple photos from iPhoto in reduced size?

    I want to send an email with multiple photos attached with a reduced size. How do I accomplish this?

    Hi Igmatteson,
    If you are using regular Mac Mail, and you are on Mountain Lion, this is what I can do:
    1. Go into Mail, and start a new message
    2. At the top, you will see 4 icons - the third one over brings up the Photo Browser from iPhoto
    3. Go through your pics and select the one you want and drag it onto the mail page
    4. Once you have done that, a small bar on the right-hand side will show up that will allow you to select whether you want the image size to be small, medium, or large. Once you select a size, all photos you add will be that same size.
    Hope this works for you!
    Cheers,

  • How to reduce size or compress PDF files?

    Hi guys,
    Does someone knows if there is a way  to reduce the size of the PDF file with good quality even on Pictures and Scanned documents? I know the option 'export', 'quartz filter' 'reduce size', but the compression is so extrem. Many files can't not been read, the quality is so bad. Is there a additional app, software or extension that let the user play with the compression on pdf files and let it be more personalized like the dopdf V7 available for windows? i am very dissapointed with this. Please help or suggestion. I will appreciate it. Thanks

    I have used the excellent PDF Toolkit app for a while, and its preformed well. Occassionaly it makes the document into a negative image...which Im noyt sure why...
    Mathishk, im trying your online version out, and am impressed and admire the fact that you have done this.
    Well done. 
    A TRICK i use often. Once all hires images are on the designed document - and its coming in at 15-20mb, just change the link to the images so they are 'missing' then make a pdf.
    i.e 'Hi Res images' to HRes images - old'
    The screen resolution of images is still great, but file comes in at fraction of the size.
    You 'trick' the document to use screen images only. So my 18mb file comes in as 5.2mb.
    Just remember to change the images folder name back, so files relink.
