Pdf optimizer image sharpening

I like the pdf optimizer in the professional version of
Acrobat, but I'm not happy with the results I'm getting with the
compressed images. The images in the original pdf are 300 dpi and
I'm compressing it down to 150dpi with the jpg compression set to
maximum. Everything looks fine after running the optimizer, except
that the now-compressed images are in DESPERATE need of sharpening.
I can't find any setting to do this in the optimizer preference
pane, which in my mind is the obvious place for it. I can't believe
that the makers of Photoshop would not include some kind of tool
for sharpening images. There should be something in there with
options similar to the jpg compression settings (medium, high,
maximum sharpening, etc.). Does anyone have any suggestions? Is
there a plugin out there for Acrobat that does what I'm asking for?
Thanks.

Adobe Acrobat Pro 9 pdf optimizer failure..

We have a problem optimizing files in Acrobat Pro 9.
When we try to optimize (Advance > PDF Optimize) the file(s) Acrobat either chrashes, or just say "an error was encountered while processing images".
It is rather large files we have, from 50Mb to 112Mb and up to 17000 pages.
We cant split them into smaller files.
I can´t find anythin in the error log.
This happends on at least 4 computers, whit diffrent settings and hardware.
Any suggestions?
Thanks.

You've likely exceeded your computers' capacity to process the necessary commands specified in the Optimizer settings chosen.
During optimization, a temp file will be created that is approximately the same size as the file being processed. The computer must be able to handle the additional load of each page being analyzed and processed. Text is not so bad, but layered images can be murder on memory.
There are some cases when an optimized pdf might actually end up being a larger file size than the original. Sometimes a simple Save As can dramatically reduce file size.
What is the goal of the optimization? How are you planning to distribute the document? Is there a reason for not providing multiple files instead of one large file? If you can give a few more details, some of the folks here might be able to give some helpful ideas.
FYI: A good article: "Understanding Acrobat's Optimizer" http://www.appligent.com/talkingpdf-understandingacrobatsoptimizer
It doesn't answer your question, but does provide good information about making optimizer choices

Exported PDF Shows Images in Adobe Reader X, but Not in Acrobat 9

I have a user who created and exported a pdf from InDesign. Now when they open it in Acrobat 9 it doesn't display all the images that were added. The Windows XP document preview pane displays the document correctly and if it's opened in Reader X it displays correctly. I've tried updating and repairing. It was suggested before that I go to 'Advanced > PDF Optimizer' and make sure encoding was set to JPEG and to uncheck 'Optimize images on if there is a reduction in size' option. The document has no problems opening on any other computer in Acrobat or Reader. Any suggestions?

So the option was already checked when opened the document. I went ahead and unchecked, closed, reopened just to test and it's still not displaying correctly.
In response to Bill@VT. The image is on top of a white background so I can't tell if there is space there or not, it's just all white.
She showed me another document that's doing something similar today. This time the pdf was done with a green background and now the background shows as white. It was created the same way with Indesign and it shows fine in Reader and the Windows preview pane just not Acrobat. I'm trying to get the user to find the installation media so I can remove and reinstall, but I'm not sure if she will be able to find it.

PDF Optimizer Removes Lines for Arrows & Circles

I'm using Acrobat 9 Pro for Mac. I've created documents that need arrows & circles around certain images, & have created PDF's from those docs. I need to optimize those PDF's to reduce the filesize, but in doing so, the PDF Optimizer removes the lines from the arrows & circles, leaving just the beginning & ending points. Here's an example of before/after optimizing:
I've changed just about every setting in the PDF Optimizer, but it still removes the lines. What am I missing here?
Thanks for your help!

I'm afraid I initially missed your "I've changed just about every setting in the PDF Optimizer," and don't have the expertise to take this much further. I assume you added your circles and arrows with Acrobat 9's commenting tools. If so, a desperate measure might be to flatten them, as discussed by Dov Isaacs a few times, most recently with regard to "Typewriter Objects," over in the InDesign forum, but I'm getting out of my depth.
Good luck,
David

PDF Optimizer enlarging size of PDFs

Hi
We have a vendor who supplies PDF files to us. These PDF files are around 4-5MB in size, and need to be reduced for the web. Using the Reduce File Size menu enlarges them to around 18MB. Using the PDF Optimizer also enlarges the files to the same size, no matter what settings/presets you use. I've tried 3rd party PDF reduction software, and they either don't reduce the file at all, or crash. No problem with other vendor PDFs.
Looking at the resultant 18MB file in Pitstop, the images haven't been downsampled at all, and have in fact lost their compression all together. The only two ways I have to compress these files is 1) Manually using Pitstop image by image, or 2) printing to PDF using the smallest file size distiller option. Both methods are too slow.
One unusual message comes up after reducing the file size: %% [Error: invalidfont; PostScript program did not contain a font ]%%
If I delete all objects except the images and reduce the file size again, it stops the error message, but the result is still 18MB. PDF version is 1.3 (4.x)
Anybody got any ideas?
Cheers,
Andrew.

Thanks for the reply Mike.
The PDF File Optimizer is what I would prefer to use, and it works very well with most PDFs. Unfortunately, these particular PDFs don't compress using the Optimizer. I've tried many different settings, even dropping the images down to 50dpi, and Low quality, but no matter what settings I use, the files always end up around 5 times the size of the original, and the images don't get compressed or downsampled.
I think the files must all be corrupted in some way, as the only way to fix them is to repdf them from Acrobat, which unfortunately is time consuming, and it's happening to all PDF files from this agency.
Cheers,
Andrew.

PDF optimizer destroying bookmarks and links

Help. I am trying to reduce a PDF book from 730MB to under 700, so it can be published on a CD. Reduce file size cannot be used as it reduces resolution of images too much. The pages need to print out well on home printers as they have detailed charts.
I am on Acrobat 8. The PDF was produced by InDesign 5.0.4.
I am using PDF optimizer but it is destroying my bookmarks and hyperlinks, though not consistently.
My images and embedded video take up 98% of the space so I only need to compress the images slightly.I have set image compression to 300, Jpeg2000, Lossless.
I have made it compatible with Acrobat 8. In Discard User Data and Discard Objects no boxes are checked, but the boxes with these titles on the left are checked.
In Clean Up settings I have 'Compress document Structure', with 3 boxes ticked - use Flate (2 boxes), and Optimize for fast web view.
What can I do to reduce the file size slightly but keep all bookmarks and links?

I'm running Acrobat 9 Professional. There may be some differences if you are running another version.
Do you have View/Page Display set to Allow Scrolling when you create these bookmarks/links? This will allow you to set Bookmarks with part of the next page showing. However, when you click on a bookmark it will take you to the top of the next page.
This is a "feature" of the software and I think there is nothing you can do about it. You can add actions to your bookmark that will zoom out and zoom in after going to the destination but these only approximate the actual destination. Using Named Destinations will not work either.
A better way would be to create your bookmarks from the Structure of your document (i.e., the Tags Panel). Bookmarks created from the Structure will allow the display of more than one page. The heading or other tagged content that is bookmarked will appear at the top of the display. The Action will look the same in the Panel, but the Bookmark has a different effect.
Interestingly, Set Destination seems not to be an option for bookmarks created from Structure.

HP Scan 1 bit scan to pdf embeds images as jpeg rather than tiff

Using HP Scan (latest version to date of 32.30.198.49673) and scanning in 'Black and White' to PDF (not 'Searchable PDF'), the image is embedded into the PDF as a jpeg (!!!), which means that the file is much larger than it needs to be, as it could go in as a lossless 1 bit tiff file. The image in the PDF looks like a 1 bit image, but 1 bit jpegs do not exist of course.
So, on a medium high image quality setting I get a file size (for a particular document) of 546KB, whereas the same scan to 1 bit tiff (on the same device with using HP scan) is 36kB (15 times smaller)
To be sure that it was embedding the scanned image as a jpeg instead of a tiff I set the file quality to low and you could see the jpeg compression artifacts which were a mixture of greys - thereby proving that it was a greyscale jpeg (of course, 1 bit jpegs don't exist), even though, visually, it looks just like a 1 bit scan in all other ways.
How can I get HP Scan, when I choose 'Black and White' to 'PDF', to embed the image as a 1 bit Tiff file, rather than a greyscale jpeg? I don't really want to store a file that is 15 times bigger in file size than it needs to be.
Thanks,
Mark

Hello @markp4000,
Welcome to the HP forums.
I understand that you would like the images saved as a .tiff instead of a .jpeg, when you scan to PDF.
Unfortunately there is no option to change how HP's software creates the PDFs.
You will most likely need 3rd party software to optimize your scanning results.

NeverCompressed list vs. CM issues on pdf or images

Symptom:
*.pdf & images causing errors on e.g. opening in CM, esp. on J2EE versions below SPS15. This might happen occasionally or always.
Technical cause:
Compression by J2EE
In J2EE default delivery 'image' & *.pdf is always on NeverCompressed key list.
Why compression might have been enabled again ?
Wrong instructions are given for compressing pdf and images in several guides:
1) http://service.sap.com/nw-howtoguides -> Portal, KM and Collaboration -> All -> How To Optimize Network Traffic in EP6.0, in Section "3.3.1 Configuring SAP Web Application Server (JAVA) Compression and Caching"
2) http://service.sap.com/nw-howtoguides -> Portal, KM and Collaboration -> Portal -> How to Fine Tune Performance of Portal Platform, in Section "3.3.1 Configuring SAP Web Application Server (JAVA) Compression and Caching"
"NeverCompressed
To enable script files compression, delete the following content types from the list: *.css, *.pdf, *.js, image, application/pdf"
Check if this recommandation was followed.
Compression doesn't make sense here roughly as compressing .gif or .jpg / .pdf does not bring any benefit of smaller content to be transfered, no beneficial ratio and is causing errors, esp. on J2EE versions below SPS15.
Solution:
- add image and *.pdf again to NeverCompressed key anyway.
- Alternatively exclude e.g. gif via Mime key value {.gif,image/gif} if other relevant images types where compression does make sense are in use.
The problematic HowTo guides will be corrected.

PDF Optimizer Inconsistent

I am running Acrobat 8 Professional on a Mac with Snow Leopard. I am trying to reduce a 48 MB pdf (every page is an image).
I am getting inconstant results when trying to reduce the file size.
I added a few links to some of the pages, then use PDF Optimizer (adjusting the image setttings to low) and got an 8 MB file (with the links embeded), which I was quite happy with.
I then realized there were a couple more links needed, so I added them into the original PDF and used the same settings but the size was 37 MB. I have messed around for an hour or two, redoing the settings, making copies of the document, restarting the computer, but I cannot get the size below 37 MB.
Any ideas? Can someone help out?

First make a backup copy, and use the backup.
open PDF Optimizer click on the following:
try the second item as I have shown and save.
Also, If the file is meant for view on the web no image should be larger than 150 DPI. set compression to the smallest you can get by with and have good looking Images. usually medium is good enough for the web/

PDF Optimization (web-optimized)

Hi,
I am looking for some capabilities of WCC 11g for optimizing the uploaded PDF files. Essentially following is what i am looking for:
Step1 User upload High res PDF files
Step2 It goes through the workflow and admin checks the PDF file
Step3 Once it is approved a Low resolution PDF file needs to be created.
So system will contain High resolution and Low resolution PDF files after approval.
I am fine till Step2, but can Step3 be automated in WCC i.e. automatic creation of low resolution PDF files (web-optimized) after approval using OOB WCC capabilities?
Do we need to setup IBR for this??
Thanks.

Are their any configurations in IBR, where PDF optimizations can be specfied?
Actually, this is not a question directly about IBR. If you see this link: http://docs.oracle.com/cd/E23943_01/doc.1111/e10800/c03_pdfi_all.htm#sthref255 IBR is just a server, which processes conversions, but conversions themselves are performed by other technologies. Oracle now holds two of them: OutsideIn, and OpenOffice, but you can also use Microsoft Office or other 3rd party conversion tools.
The mentioned chapter in the manual also provides information what parameters can be set up at the IBR side - unfortunately, resolution or size is not listed.
You may have to get accustomed to other technologies - for OutsideIn (OIT) see http://docs.oracle.com/cd/E26550_01/index.htm
I have checked it real quick and OIT has an option to modify resolution of graphical images...
...which leads to a question: what exactly is your use case? As far as I know PDFs can be with the textual layer, or graphical ones (a simple test: double-click a word in a file and when it highlights the word, it has the textual layer). I'm not sure if resolution can be changed for textual PDFs (except for few images, that of course might be contained). Also, what are the reasons for having a "smaller" PDF?
Can this low resolution PDF file be created after the workflow is approved?It certainly can. I am not, however, aware of any method how to do this with a customization.
Out of my head I can think of two methods:
- conversions are performed during CHECKINs - you could customize these services not to perform conversions, create your own service that would do it, and call this service explicitly when an item is release from a workflow
- read also http://docs.oracle.com/cd/E23943_01/doc.1111/e10800/c02_ibr_all.htm#sthref29 This contains an option: http://docs.oracle.com/cd/E23943_01/doc.1111/e10800/c02_ibr_all.htm#CBHBGGCF If you could a) modify the file format at the end of a workflow b) resubmit the item (it is possible, but only manually from the Repository Manager) you could achieve the required without modifying the services.
Somehow, I don't like either of these methods. If feels there must be something simpler, but I don't know where to find it.

PDF Optimizer decreases resolution, increases file size

I've noticed that the file size of my PDF files INCREASES now when I optimize them now that I've updated to version 7.0.7. The image resolution still decreases but the files increase significantly. For example, I have a 2 page document that originally was 3.2mb as a hi-resolution PDF. After I optimized it down to 72dpi for the images the file increased to 20.5mb!! I use this feature for documents that we publish on our web sites or to send a proof to a customer.
Is this just a new bug in version 7.0.7?

MAC G5, 1 gb RAM, OS 10.4
Indesign CS3
Acrobat version : at least 7.0.6 or newer (I'm not at work to verify the version)
I'm having the same problem. Doing a SAVE AS does not fix anything.
I have created a High Res PDF of a 56 page catalogue using Indesign CS3. I had to divide the document into two sections. The first file is 131 megs and the other 78 megs. I have to print high res for the client. Then I need to downsize the resolution so that I can send the catalogue to the client. Whether I choose PDF Optimizer or Reduce file..., the 131 megs PDF became 1.27 GB and not to mention the time wasted! This is enormous! I assure you that I have checked all settings for the PDF.
To counter the problem, I have to do a SAVE AS POSCRIPT file. Then I reduce the size using Acrobat Distiller. The 131 megs file then became 21 megs, which is what it should have been with Optimizer.
I don't understand what's happening with the Optimizer? It seems that there's an update version that has installed this bug. Which one? How to fix this problem? Is there anyone on this earth that knows what to do?

Scripting the PDF Optimizer

Hi folks
I'm trying to find a way to script the PDF optimizer in Acrobat Pro 9 (Win), so it is invoked from JavaScript with the name (or path, whatever) of a profile to use when optimizing.
This feels like it should be a FAQ, but a search of the forums doesn't reveal any posts and I've had no luck with Google or with the Acrobat scripting documentation. I can invoke the scripting UI with
app.execMenuItem("PDFOptimizer");
... but not select a profile or accept the dialog. There doesn't seem to be a proper scripting API for it. Am I just blind? Or is there no way to do this? It seems like such a basic task to use Acrobat for.
My use case is automating a weekly time-consuming PDF processing task so it can be performed in a couple of simple steps by staff without requiring error-prone checklists. One of the requirements is to save two different optimized versions with different resolutions used for image resampling.

Thanks for confirming that.
It's such an obvious use case that I guess Adobe must not want Acrobat Pro being used where Acrobat Server could be sold. Oh well. I'd use multivalent or pdftk, but neither offer image re-sampling or attachment stripping at the moment.
This limitation means users have to babysit the script a bit, which is unfortunate, but not the end of the world.

Pdf optimization

Hi at all
How can I reduce then dimension of pdf file obtained by application "Image Capture" (and Epson Rx500 multifunction scanner) ?
For example scanning one page at 200 dpi - 8 bit deep color, result a file with huge dimension: about 2 Mb !
Thanks

Hi Maarten.
PDf optimization comes with a variety of distiller engines. It requires for manual configuration. Just check the following URL

Bridge CS4 won't output to pdf multiple images with same filename

Hiya...my googling efforts have thus far failed!
I've got CS4, and in Bridge, I created a New Smart Collection to find all filenames in a folder containing "." or ".jpg" - which in turn searched through all the subfolders like what you used to be able to do in Photoshop CS3. Very simple stuff, but all the images are jpg's, but in multiple folders (I don't want to move them out of the folders, as the files came from an external source, and there are heaps of folders, and I don't want to pdf each subfolder seperately as it will take forever).
The problem is that some of the files have the same filenames (again I'd prefer not to rename, as it happens a lot on this project, and they are all over the place). So whilst Bridge will show the thumbnail images correctly in the content tabbed screen in my New Smart Collection, but once I've done the Output to PDF thing, for example, instead of showing both different images it has pdf only the first image but repeated it twice. And this happens multiple times throughout the pdf, the more times the same filename is used, the more times the first image gets repeated.
I know that it is messy to have multiple similar filenames, but why can't bridge just place the image anyway? It allocated a space for it on the pdf and does show it in bridge, it just doesn't seem to survive the transfer to pdf well.
The only other thing that I have done is use the below link (which was posted on another adobe forum thread) to create a custom pdf output template (nothing too fancy, just number of rows / columns, size, font etc). But I've tried using the standard bridge templates and it does the same thing.
http://www.proficiografik.com/2009/08/03/save-custom-pdf-output-template-in-adobe-bridge-c s4.html
Any help would be appreciated...even if to tell me that I am being unreasonable!
UPDATE 16/11/09
Just to let you know that I seem to have resolved the bug inadvertently with one of the Adobe updates. The below is the link for the AdobeOutputModule-2.1-mul-AdobeUpdate.zip which was released on 2/19/2009 - which allows for headers & footers to be placed in the Ouput pdf. I finally installed it today, and everything seems to be working fine now (i.e. I can pdf multiple images with the same filenames and the pdf will actually show each different image rather than repeating only 1 of the images).
Must have been a fix installed in the contact sheet templates that get installed with the update - not sure why the original version was corrupted, but I've left that with the Adobe guys (I submitted a bug report - and they were able to replicate the problem but hadn't fixed it as yet).

When I click import from disc I am asked to choose a disc and then I get this message:
The following photos will not be imported because they are already present in the catalog. To see these photos in the catalog select 'Show in Library' (the import will be canceled).
This is followed by a long list of images. If I click 'Show in Library' I can see all the images with the same filename. And then they start to automatically write over those images with images from the disc. However they keep the same metadata and keywords from the previous images. If I click on Import and deselect the "don't reimport suspected duplicates" box, it imports only the images that don't share filenames and none of the images that do.
Is there a way of setting the "Don't reimport suspected duplicates" box in preferences?

Problem in creating client side PDF with image using flex and AlivePD

I need a favor I am creating client side PDF with image using flex and AlivePDF for a web based application. Images have been generated on that pdf but it is creating problem for large size images as half of the image disappeared from that pdf.I am taking the image inside a canvas . How do i control my images so that they come fit on that pdf file for any image size that i take.
Thanks in advance
Atishay

I am having a similar and more serious problem. It takes a
long time to execute, but even attaching a small image balloons the
pdf to 6MB plus. After a few images it gets up to 20MB. These are
100k jpeg files being attached. The resulting PDF is too large to
email or process effectively. Does anyone know how to reduce
size/processing?
