PDF CMYK TIF Color Changes on "Reduce File Size"

I run a Mac G4 MDD w/1GB Memory and OSX 10.4.11. Use Acrobat Pro 8.1.2 for PDF viewing, manipulation, forms, making large size files smaller, etc. Recently, I noticed an odd color change on one of 72 ads I am doing for a small 24-page publication. The background image of the ad is a CMYK TIF file placed in a QXP 7.3.1 document. After working on a revision to a previous ad, using the same set-up in QXP, the ad I created, using Output to PDF, opened in AcroPro correctly rendering the ad and background as the other 31 ads I had been working from or on. All the ads are different and have different backgrounds as well. Each ad opened in AcroPro has been made smaller by selecting "Reduce File Size" with no changes to color, drop shadows or text. But, when I selected that (RFS) menu for the 32nd ad, that background color changed completely to a lighter and much more contrasty image. I checked the TIFF background file in PS CS2 to see if it was CMYK or any different than the others. It was like the others, properly rendered and saved, but was much deeper in color. I went back into QXP and noticed the TIFF file in question had a 30% opacity selected to the image. I thought if I saved the original TIFF in PS with a screen tint overtop and flattened to the same look as the intended ad that would solve my problem. I placed that new TIFF background into the ad in QXP and made sure the opacity was 100% and output PDF as I had previously. Unfortunately, the ad turned out exactly the same with the same color shift. There must be something else causing this color change to occur, so if someone else has experienced this and can suggest an answer or posting that may help please advise. Thanks

Cathy,
You have posted your question in a forum dedicated to the Final Cut Studio application Color. It is a very specialized program to grade (adjust) the color in video/film images. We know nothing regarding PDFs.
Have you tried posting this on an Adobe support site?
Good luck,

Reduce file size with action wizard

(German version below)
Hey,
I got two questions for action wizard in Acrobat XI Pro.
I try to reduze file size of many PDFs using acion wizard. My tests worked fine but now I got some problems I try to explain now:
1. I add a directory with many subdirectorys to my process list. Adobe now adds not only PDFs to my list, it also adds JPGs, DOCs etc. That means I have to delete every single file I not want to convert to PDF cause I only want to reduce file size of excisting PDFs. Is there any possibility to only add PDFs in my processing list?
2. If a PDF is opend by any other user I get a information about it. This info I need to acknowledge every time it pops up cause my process interrups. Is there any possibility to ignore this info?
I´m happy for any help i can get here. Thx.
Regards
(Sorry for bad english, it´s not my favorite language )
Hallo Leute,
ich benötige Hilfe beim Benutzen des Aktionsassistenten im Acrobat XI Pro.
Ich versuche bei sehr vielen PDFs die Dateigröße zu verringern. Dazu habe ich mir eine Stapelverarbeitung per Aktionsassistent erstellt die bei meiner Testumgebung auch super funktioniert. Leider habe ich noch einige Probleme für die ich Hilfe benötige:
1. Wenn ich einen Ordner mit sehr vielen Unterordnern und verschiedenen Inhalten einfüge möchte ich eigentlich nur die PDFs verarbeiten. Leider fügt Acrobat auch alle JPGs DOCs etc. hinzu. Ich muss also alle unerwünschten Dokumente herausfiltern, da auch keine sortierung vorhanden ist. Bei mehreren Tausend Dokumenten nicht leistbar. Gibt es hier eine Möglichkeit nur PDFs in die Stapelverabeitung aufzunehmen?
2. Sollte die Verarbeitung mal laufen kommt es hin und wieder vor das die PDFs durch einen Benutzer geöffnet sind. Ich bekommen hier eine Meldung von Acrobat die ich erst bestätigen muss bevor es weiter geht. Da das Programm eigentlich über mehrer Tage/Wochen im Hintergrund laufen soll passt mir das gar nicht wenn ich alle Stunde überprüfen muss ob die Stapelverabeitung noch läuft.
Ich hoffe es gibt jemanden der mir helfen kann. Ich bin über jede hilfreiche Antwort glücklich.
Gruß

For starters, let's refer to your original post: "this is indeed a serious problem and step back in functionality..." This statement is a quite ridiculous assertion, unnecessarily dramatic, wholly inaccurate, and unhelpful. Your statement "is this a joke" and "I know Acrobat tends to choke...etc..." is just pure gibberish and polemical. It is quite easy to feed any application enough data to cause a performance failure, but one would really need to question one's motive and prudent use of one's time at this point - unless you are tasked with stress and load testing the software to determine minimum working requirements.
'Batch Processing' is, since Acrobat 9.x, dead and gone, Acrobat 11's approach is to aggregate many hitherto unavailable tools and commands and allow the user to create custom workflows. More interactivity has been built into the process, which may or may not be desirable in each case depending on the workflow context and requirements. But we have obviously moved away from the concept of processing a large number of files and towards a more targeted and effective processing of smaller sets of files. The default Actions we deliver with Acrobat 11 reflect this intention.
The feature "Batch Processing", which was an Acrobat feature from A5 (I believe) up to A9, previously had been hidden in Menu/Advanced/Document Processing/Batch Processing has been wholly replaced by a completely overhauled framework called Actions, now part of the Tools panel, and will be immediately accessible when Tools is called in the UI.
Thus the obscured Batch Processing may have been a tool considered and used by an extremely small set of users to do exactly that, i.e., batch process a large number of files, but had been fairly inflexible, generally speaking, and buggy. We were very well aware that if we were to overhaul the feature, add a considerably larger number of available tools and commands in Acrobat, provide wide possibilities for customization built towards specific workflows, and bring it to the forefront, we were going to sacrifice some of the aspects of batch processing a large number of files. Not calling it "Batch Processing" anymore - because it isn't - may be an indication of this intention.
Personally I have used and tested Batch Processing periodically during various Acrobat projects, but I don't remember encountering the "Reduce File Size" command - which is a subset of Save and file optimization - to use within a batch sequence. I may be wrong, and your screen shots would be welcome here. In fact go ahead and construct a batch sequence that (1) uses 'Reduce File Size and (2) applies file type filters to it, and post it either here or to me privately. I would be happy to be wrong. But regardless, we are grateful for positive input that points out defects, allows us to improve the functionality of the product, providing the intended changes are reasonable, and that the communication of said issues remain respectful of this process and of the individuals we depend upon to implement these changes. The tone of your response comes very close to rendering a proper consideration of this issue irrelevant.

How do I reduce file size in Adobe 9.4.5?

Hello,
I'm using Adobe 9.4.5. I can't figure out how to reduce file size. My 'save as' options don't offer this because they only offer 'save a copy' or 'save as text'. And I don't have the 'Document/reduce file size' option. It's simply not there.
I'd appreciate any advice on how to do this.
Many thanks.

You can also try Document>Reduce File Size. The PDF Optimizer has more features, but Reduce File Size my meet your need. I find different results with both methods, making me sometimes wonder which is the best approach.

Running reduce file size results in excessive I/O

I'm running Acrobat 9 Std on Windows XP. I've noticed many times that when I load a PDF into Acrobat and select the reduce file size option, the amount of I/O and time taken to completion seems extraordinarily large. By far the longest part of the process is subsetting embedded fonts. For example, at the moment I have a file size reduction running on an 80 page 10Mb PDF. So far it has been running for about an hour, and Task Manager shows that Acrobat is using almost 600Mb of RAM, a fairly constant 55-60% of CPU, and I/O reads are over 10Gb and writes over 15Gb. The computer has 4Gb of memory and Acrobat is the only application running, so swapping is not the cause of the slowness. I have other larger manuals (some of them about 800 pages long) that I periodically need to run this process on, and those can take almost a day to complete the size reduction, with Acrobat reading and writing over 100Gb to complete the size reduction.
These manuals are all produced by running texi2pdf on the texinfo source (both HTML and PDF get produced from the one set of source files), so there is nothing I can do at PDF creation time about the size of the created files. I can usually achieve about a ~50% size reduction by running them through Acrobat, but the way that it does this seems extremely inefficient.

You might also want to look at the PDF a bit. You can check the document properties to see what fonts are included. Sometimes with LaTeX, a new set of fonts is included for each graphic or such. I have seen some wild results that really bloat the file. Also, you might try some of the preflight scripts to see if they can resolve some of the issues.
Might the PDF actually be a graphic collection and not contain any text? There are several possible solutions, some that might help are not generally recommended, but knowing what the PDF is like would help. If you could extract a few pages and post them someplace (dropbox or acrobat.com possibly), we could give a better answer maybe.

PDF reduce file size filters and CMYK to RGB conversion

This doesn't seem to be on-topic to this forum, but I'm hoping someone here has the expertise to answer my question. We have some scripts which take a series of press-quality pdfs and use the "reduce file size" filter to prepare them for viewing on the web. We run these scripts on a 10.4 machine, and the filter works very well, reliably reducing file sizes of all sorts of pages.
When we tried to upgrade the machine, we discovered that the quartz filtering has changed in 10.5 and 10.6. While it's usually an improvement, getting maybe 5-10% better compression ratios, it has become unreliable in that about 5% of my files fail spectacularly -- they blow up to 3, 4, 5, 6 times the original size.
The other thing that happens is that the 10.5/10.6 filters munge the colors up. I found the solution to this -- in the ColorSynchUtility, make a duplicate of the Reduce File Size filter, and add a Color Management Component called Convert To Profile. This allows me to set a filter that converts the CMYK content to RGB. The problem is that there are about 40 choices of profiles, and it's not at all clear what I should use. Many of them have printer manufacturer's names in them, some say "Adobe", others have cryptic codes (probably referring to various RFCs and schemes). I've tried a couple of the ones that don't look like they are for printers, basically chosen at random. They all produce files of slightly different sizes for the reductions that go well, but on the files that blow up, some filters are better than others. (For example, I have a 5MB page which reduces to 1.4MB with the 10.4 filter, but blows up to 27MB with the "sRGB IE61966-2.1" profile, but only 12MB with the "Adobe RGB" profile.)
So I have 2 questions:
1) Is there any way to configure a 10.5/10.6 custom profile so that it behaves as reliably as the 10.4 "stock" PDF Reduce File Size works? It doesn't have to be the most wonderful compression algorithm out there, just so that it never or rarely has a file blow up in size.
2) For converting press documents to pdfs that are going to go on the web, what is a good "Convert to profile" to use of the 40-some choices on the pull-down menu?

Automator pdf reduce file size action

I have a saved action to reduce file size for pdfs and want to change the resolution, but it's grayed out. Can someone tell me how I can do this?
Thank you!

Colorsync Utility: PDF Compression vs. Reduce File Size filters

What's the difference between these two? I used Automator to make two applications, which I think I screwed up, because they're not reducing file sizes now. 1 would make 100+ pngs into a pdf and use "reduce file size," I think. 300 MB would become 80 MB, e.g. I would then use a not-so-great PDF application called PDFStudio9 (because I lost my Acrobat DVD and couldn't get a replacement) to OCR that reduced-size pdf. At which point I would run the other application, which I think compressed the OCR'd pdf. Which would be about 40 MB at the end. But I'm not sure if that's the order of compression I used.
So what's the difference between the two types of filters, and when would I want to use each for ultimately creating a non-titanic-sized pdf?

Compress PDF vs. Reduced File Size Quartz Filter?

Sometimes the PDFs I produce through the print function get pretty huge.
In the PDF drop down on the print menu there is a compress PDF option that I sometimes use.
Then someone said I should go to print, to the copies and pages, select "colour sinc" and on the Quartz Filter select "Reduce File Size" then hit the "save as pdf" on the pdf button.
I have no idea what I just typed
What's the difference between the two approaches and which would produce the best quality PDF at an manageable size?
I just tried PDFing this page using the three options -- regular pdf, compressed pdf and that colour sink / quartz filter / reduce file size. Damned if the smallest file isn't the regular (at 76 kb) next is the reduced (92kb) and the largest file is the compressed (140kb). Maybe not a proper test but what the heck?
Any thoughts?
Thanks

I believe that the same filter is applied no matter whether it is done through the Compress PDF button, which is an Automator action, or using ColorSync.
If you would like to experiment with it, you can also apply it through the ColorSync Utility. If you copy the Reduce File Size filter, you can change the amount of reduction done. You can preview the results there, too.
The filter only affects images, not text.

Reducing file size by changing the photo size?

I inherited a bloated pages file with some photos over sampled at 14Mb+ Probably should be about 500k.
I want to open the file's package contents and edit the images using graphic converter. So far my attempts have resulted in the physical size reducing on the page. Anyone with a tip to reduce the resolution of the photo with out the result shrinking on my layout?
thanks

Well to answer my own question
1) for PDF files–open in preview>>save as>>select quartz filter- reduce file size.
2) for tiff/jpg open in image editor and change the resolution. Save as to NEW location.
in pages select the image and under format>>advanced menu "set as media placeholder" drag new image to this place to replace. TIP drag the icon in the title strip at the top of the saved file instead of locating in finder.
NOTE: for 2 if the image has been masked the pages image will need to be resized.
Of course this only works if the placed images have high resolution to start with or have been shrunk in the pages layout.
I had a 120Mb 5 page file that is now under 10Mb

Reduce File Size in Acrobat Pro (9.5.5) Corrupts Graphics in PDF Documents - shows up as black image

Whenever I use Reduce File Size in Acrobat Pro (9.5.5), sometimes some of the images (not all) get corrupted and show up as a black image in the new document.
Actually, the new reduced document looks okay when viewed in Acrobat, but the problem shows up when viewed in the Preview application on the Mac.
I'm using Acrobat 9.5.5 with Mac OS 10.8.6
I've tried re-importing the graphic into a new graphic box, which didn't work. Thinking there may be some type of corruption with the actual graphic file, I then tried viewing the graphic, then taking a screenshot of it to create a completely new file, and then re-importing the new graphic file into the original document (created in Adobe In Design 5.0.4). I then export the new document as a pdf, and brought it into Acrobat Pro to do the Reduce File Size. Same thing happens - black box appears where the graphic was.
I then tried using the Reduce File Size within the Save As function of the Preview application on the Mac - while the graphic remains intact, many of the other graphics in the document are "reduced" too much, to the point where the image quality is seriously degraded, and therefore not usable.
Any other ideas?

Hi Anoop,
I can share the graphic file, but not the pdf which contains it (as it contains confidential information) - thanks!

How do you reduce file size of a PDF if Save As doesnt work?

I have been trying to reduce the size of a PDF, using the Save As > Optimized PDF method.
I have also tried Save As > Reduced Size PDF.
This is on a file made up of 20 pages of full page Jpegs. (These were generated by the script in Photoshop that generates Jpeg files from Layer Comps within the document.)
If I use Reduced Size PDF, I get a greatly reduced file size but the image quality suffers greatly. (Lots of artifacts and blurryness)
There are no options to choose the level of compression I want.
If I use Optimized PDF method, I cant seem to reduce the file size no matter what I set the Jpeg compression to.
Is there some way to cut the size of the file down but not lose so much image quality?
Any suggestions?

Part of the problem here is that the files that are produced when I run the script to output files from layer comps are very big.
If I "save for web" for each layer comp, I wind up with way smaller Jpegs. Thus a much smaller PDF.
So the question is: Can you make the script, Layer Comps to Files, create smaller more optimized Jpegs? (Like you get when you save for web)

Reducing file sizes of multiple PDF's

Hello everyone,
I just got hired at a structural engineering company, and we are trying to go "paperless". I am in charge of scanning tons and tons of our old record drawings. We have an old scanner and the PDF's it creates are anywhere between 10,000Kb to 70,000Kb. After I scan every sheet, I am supposed to use the "Reduce file size" option in Adobe Acrobat. I am using Adobe Acrobat 7.0 Professional and I always make the files compatible with 5.0, which reduces the file size by 1/6 - 1/10. I've only been able to reduce 1 sheet at a time, which again, is time consuming. Is there a way I can reduce multiple files at once? I looked online and found an article here: http://help.adobe.com/en_US/Acrobat/9.0/Standard/WS65C0A053-BC7C-49a2-88F1-B1BCD2524B68.w. html, saying that in Adobe Acrobat 9.0, I can select "Apply to multiple" to reduce multiple files. Is there a way I can do it without upgrading?
Thank you in advance.

Unfortunately, it's not possible if you're using Acrobat XI. In previous
versions you can tell an Action to ignore non-PDF files but this feature
was removed in XI. Also, 35,000 files is way too much for Acrobat to
process. You need a more robust application for such a batch processing
task.

PDF Reduce File Size makes certain pdfs HUGE

Generally reduce file size works great for me but certain files, those coming from someone using Microsoft Publisher in particular, result in larger pdfs. She sends me newsletters for a website and sometimes the 3 page pdfs are 2-4mb. I tried opening in Preview and re-saving them using the Reduce File Size filter and the result is that they ballon up to 50-100mb!! Info for the file reveals that the pdf producer is GPL Ghostscript 8.15 and the content creator is PScript5.dll Version 5.2.2. I seem to be able to open and reduce file size using Acrobat so I'm not quite sure why Preview is choking on them.

Hi geekinthegarden- This does not surprise me. There are many variations and reiterations in specifications of the PDF format.
Going from Ghostscript language interpreter, to Apple in rendering could introduce complications which we will not be able to sort out in this forum encapsulating a complete description of a fixed-layout 2D documents that includes the text, fonts, images, and 2D vector graphics which compose the documents.
Suffice to say it is not a perfect science.
Print PDF has a compress PDF file option as well as ColorSynch in your /Utilities folder +reduce file size+ option for PDF's. This may or may not be of use.
You found your workaround using Acrobat, this is part of the value of having more than one PDF viewer, good computing!

Making a interactive PDF from indesign, but it's too big. Tried to reduce file size in Acrobat, but

Making a interactive PDF from indesign, but it's too big. Tried to reduce file size in Acrobat, but it does not reduce file size.

Use the Optimize PDF command in Acrobat, it gives you more control. I think it's under the Advanced menu in Acrobat 9 Pro and File > Save As > Optimized PDF in Acrobat X Pro.
You might try playing around with different settings. You can also click the Audit Space button at the upper right to see if its from images or other things causing the file size problem.
Unfortunately, InDesign doesn't write interactivity in a very optimized way. You get better results with buttons, for example, creating them in Acrobat Pro and using the Duplicate command to duplicate them across multiple pages.

I want to reduce pdf size up to 5mb for mailing perpose, anybody have any option to reduce it since I have used optimiser & reduce file size option but its not helpfull.

I want to reduce pdf size up to 5mb for mailing perpose, anybody have any option to reduce it since I have used optimizer & reduce file size option but its not helpful.

The optimizer can reduce space, but some things can't get smaller. Text for example. Play with the settings, examine the results of Audit Space Usage.
Or give up. Even 5 MB is too large for a bulk mailing, by far. Instead put it on your web site and mail a link - done!
