PDF Files Appear Low Quality

I often use Adobe Reader on my Android tablet to read ebooks I have saved as PDFs. I've noticed that often after reading the first few pages the pagws start appearing as what looks like a low quality JPG. This only appears on Reader for Android, and changes back to high quality if I zoom in the page, that would suggest to me that it is caching the pages in a less than desirable way.
It would be great if this is changed as the compression artifacts are quite annoying, particularly on the larger screens found on tablets. If it helps at all I'm on Android 4 ICS.

A very good example I've found is the "How to use Adobe Reader' PDF included with the latest version, which appears particularly low quality, especially if I click a web link on it then switch back to reader.
It happens on all PDF's, with minor compression artifacts appearing around the text and the white background changing to a slightly yellowish tint. If you believe it would help then I'm very happy to send one of the documents I have, but as I've said the problem is with all documents.
My tablet is a HP Touchpad that I've installed Android on.

.pdf files appear as a gray screen

.pdf files appear as a gray screen when downloading from a website link since upgrading to Snow Leopard. They (pdf files) are fine when received and opened from an email sent to us. Any ideas on how to fix it?

First I Reset Safari, then close Safari then navigate to:
Home/Library/Preferences and look for and then remove
com.apple.Safari.plist
com.apple.Safari.RSS.plist
Also:
Home/Library/Safari/ folder and remove the following two files:
history.plist
lastsession.plist
And
Go to Home/Library/Caches/Metadata/Safari/ and remove the contents of that folder.
(These are just webhistory files and are not required for Safari to run. However, similar to preference files, problems can arise if they have become corrupt.)
Locate the cookies.plist file that's located in the Home/Library/Cookies/ folder and remove it.
They will all be recreated next time you launch Safari.

My PDF file appears to be too large/complex to export. Can I split it in some way?

My PDF file appears to be too large/complex to export. Can I split it in some way?

Good day Colin,
In order to split a PDF file, you'll need to use Adobe Acrobat.
You may want to try turning off the 'Recognize text' option and converting your file again, it may help.
Kind regards,

Saving PDF File at Lower Magnification

I have a PDF file that is at 162% when opened. I reduce that to 100% but can't find a way to save it at that magnification. If I resave it at the lower magnification, it still opens at the higher value. If I print it to a new PDF file with Print Adobe and then open that file, it still opens at the higher magnification (162%); it's the same as the original. I've looked but seen to find out how to save the file at the lower magnification. I'm using Adobe Acrobat X Pro.

Duplicate Image object in PDF file with low resolution

Hi all,
On creating images in bitmap mode using illustrator into eps format and convert the eps file into pdf using acrobat distiller.
On pdf file its showing two objects in the content panel with one object present in low resolution other one same as its original.
It will not happen in direct pdf from illustrator
Please anyone help on this.
Note: It will not happen in grayscale mode.
Regards,

Hard to follow what you are experiencing, can you post screenshots?
You may want to experimnent with your .eps settings, especially preview & inlcude linked files since you have duplicate images.

Xournal pdf exporting of lower quality

I added some highlighting and text to the original pdf within the xournal. But the output quality of the original pdf changes (text with drawing), after exporting. Is there a way around.
http://xournal.sourceforge.net/manual.html#printing
states:
"If Xournal is unable to parse the PDF file, the poppler/cairo renderer is used instead to generate a new PDF file from scratch. "
Thanks in advance.

The problem was in "printing" the PDF.
The issue was completely resolved by printing the iBA file to a Post Script file, and then indepently using Adobe Distiller to produce the final PDF.
It makes no sense to me why using Print to Adobe PDF from the iBA print menu works any differently than using Distiller on a .ps file. But whatever, it works, and it is beautiful.

Cropped .pdf files appear uncropped

I have all of the latest downloads for OS 10.5.1 and iWork.
I scan images on a copier and email them to myself as .pdf files.
I open the .pdf files in Preview and crop them as needed.
Then, when I try to import these cropped images into Keynote the images appear as their original full frame.
Anybody know why? How to stop this?
Thanks!

I think this is currently a bug. One workaround is if you take the cropped .pdf then do File -> Print and THEN click Preview there. When the Preview window opens, you should be able to copy that and have it work for you.

Does repeated saving of a pdf file degrade its quality?

Hi experts,
I have been asked the following question: Do repeated editing and saving degrade the quality of a pdf file (containing text and image)? I hope some experienced folks can help me answer the above question.

lq,
Are you working in RGB Color Mode? If so, you will almost certainly be disappointed when the colours are squeezed into the smaller CMYK gamut.
There may also be a question of colour management/settings.

Batch script to print PDF files to press quality

Hello, I'm looking for a way to print PDF files to the Adobe PDF driver with "Press Quality" setting.   Ideally I could also save any file attachments first and then reattach them after printing to new files.
I've been experimenting with the batch sequence feature but I am not getting very far.   Are there any sample scripts that do something similar to this?   I appreciate any guidance you can offer.
Thanks
LLL

No, I do not have access to the original files that went into making the source PDFs.
I've looked at PDF Optimizer but it does not shrink the file size nearly as much as printing the file through the Adobe PDF print driver with "Press Quality" setting.   I suspect this has to do with font consolidation.   PDF Optimizer seems to let you unembed fonts from the file but that's not what I'm looking for. I need to have all fonts embedded.
I appreciate the feedback. Anyone else have ideas here on the original issue? Thanks.

Help! INDD PDF file appears pixelated when projected, but not on laptop

Hello, all,
I'm preparing an important presentation and want to ensure that my slides look great when projected at an event next week. I'm concerned because at a practice pitch a couple weeks ago, they appeared pixelated when projected, even though they looked beautiful on my laptop screen. This includes fonts and vector graphics. I had created the slides in InDesign 6 and exported to PDF. I'm posting screen shots of the file settings for each below. Should I have done something differently? Can anyone share best practices for exporting to PDF when the intent is to project the PDF from a laptop? I would really appreciate any advice. Thanks!

Waiting on technical details of projector

If you're displaying the PDF with Adobe Acrobat or Adobe Reader then any vector content (graphics and text) will scale perfectly; the document setup in InDesign has no bearing other than to set a 4:3 aspect ratio for the pages (PDFs don't measure in pixels). As Rob says there's no getting around the resolution of the projector.
Given how PDFs behave there's no complex 'best practice' guide for on-screen or projected content driven by a desktop computer. You can work in any color space and use any combination of transparency, raster and vector content you wish, then just run Export > Interactive PDF with the default options. If you're displaying via a mobile device it's a good idea to work in RGB, as some PDF-reading apps will mess up CMYK>RGB conversion, and don't bother with any rich media (Flash/video).

AE CS 5.5 Mac OS 10.7, Imported screen captured .mov file is low quality

Hello
I'm importing a few screen grabs that I made using Snapz Pro video. The quality of the original file is great. But when I import it into AE CS 5.5, and then zoom in and animate it, it looks really, really bad ONLY when I render at 1/2 resolution.
If I did the same thing to images, they would look fine. But this movie asset (h264) looks horrible unless it's rendered at exactly 100%.
To be clear, this only happens at render, and in the preview pane when the pane or render are set to less than 100%. If I view or render at 100%, it looks fine.

Seriously?!?!
What version of After Effects? Include the minor version number (e.g., After Effects CS5.5 with the 10.5.1 update).
10.5.1
Have you installed the recent updates? (If not, you should. They fix a lot of problems.)
Yes
What operating system? This should include specific minor version numbers, like "Mac OSX v10.6.8"---not just "Mac".
Os X 10.7.3
What kind(s) of source footage? When telling about your source footage, tell us about the codecs, not just the container types. For example, "H.264 in a .mov container", not just "QuickTime".
H264 .mov captured with Snapz Pro Video
If you are getting error message(s), what is the full text of the error message(s)?
None
What were you doing when the problem occurred?
Rendering at half resolution, or previewing at half-resolution (also happens at other resolutiosn below 100%)
Has this ever worked before?
Huh?
What other software are you running?
Chrome
Do you have any third-party effects or codecs installed?
Surprisingly, no.
Tell us about your computer hardware. Include CPU type and number of processor cores, amount of RAM installed, GPU, number of disk drives, and how any external drives are connected.

Do you have any third-party I/O hardware (e.g., AJA, Matrox, Blackmagic, MOTU)?
No
Are you using OpenGL features in After Effects?
Yes
Does the problem only happen with your final output, RAM preview, or both?

FAQ: Creating PDF Files from FrameMaker v.6 & earlier Documents -- Why you should not use "save as PDF"! -- Windows & MacOS Only!

An issue that has come up over and over again on several FrameMaker and Acrobat/PDF email lists as well on the corresponding Adobe User-to-User forums is that of creation of PDF files. FrameMaker 5.5.6 and 6 have what looks like a convenient feature that is supposed to allow you to create PDF files via simply saving the document as a PDF file. I have gone on record as advising end-users not to use this approach for reliable creation of PDF files from FrameMaker documents under Windows and MacOS with FrameMaker 6 and earlier. Why do I most vociferously offer this advice and why doesn't the problem get fixed? And how SHOULD you create PDF files from FrameMaker?
GOOD NEWS
I will start with the good news. The "next major version" of FrameMaker will indeed have "save as PDF" re-implemented in a manner that it will be as reliable as printing to the "Acrobat Distiller" printer instance under Windows or the "Create Adobe PDF" desktop printer under MacOS. I am personally working with the FrameMaker development organization to make sure this really happens and is fully and properly tested and debugged! Furthermore, this next major revision of FrameMaker, unlike FrameMaker 6, will come with a Distiller installer that will properly install the "Acrobat Distiller" printer instance under Windows and the "Create Adobe PDF" desktop printer on the Macintosh (of course assuring that the latest PostScript driver is also automatically and correctly installed).
DON'T USE "SAVE AS PDF"
But what's wrong with "save as PDF" as currently implemented?
The following are some of the SYMPTOMS reported over the last few years by FrameMaker users that were traced back to use of "save as PDF" under FrameMaker:
(1) No PDF file is produced at all, possibly with a log file showing not-readily apparent PostScript errors during distillation.
(2) The PDF file "loses" color in images. All or some images (raster, bitmap images, NOT vector artwork) appear in the PDF file in grayscale.
(3) The resultant PDF file is on the wrong paper size, i.e., the document's logical page size does not match the output page size as seen in Acrobat or Acrobat Reader.
(4) Some or all text in the resultant PDF file is blotchy looking or overly bold.
(5) Some or all text in the resultant PDF file cannot be searched or indexed.
(6) Some or all text in the resultant PDF file appears in Courier or in some other substitution font.
(7) Interword or intercharacter spacing is a bit irregular in the resultant PDF file.
(8) Content is missing in the margin areas of the page, i.e. you cannot do full-page bleeds.
(9) Some or all page content is missing (other than margin areas).
(10) Relatively inefficient PDF is generated.
If this list by itself isn't enough for you, please note that some of these symptoms are very subtle and may escape attention when the PDF is first viewed or printed. Oftimes, it is when one attempts to manipulate the PDF file in Acrobat or repurpose its content or even view or print on a system other than the one on which the PDF file was created, that some of these symptoms make themselves obnoxiously visible (or invisible in some cases I won't make any bad jokes here about graphic examples!).
It is important to understand that FrameMaker does NOT have its own native ability to create PDF. Any and all PDF created from FrameMaker documents is actually done by creating PostScript via the PostScript driver and having the Acrobat Distiller create PDF from that PostScript. The only exception to this is creation of PDF via the Acrobat PDFWriter driver, which is likewise not recommended (see below).
In order for "save as PDF" to work correctly, FrameMaker must do the equivalent of calling Printer Setup and selecting the "Acrobat Distiller" printer instance under Windows or the "Create Adobe PDF" desktop printer under MacOS followed by setting the driver's options correctly for paper size, page range, etc., followed by sending the proper commands to the driver to create PostScript.
Contrary to popular belief, PostScript as generated by the Windows and MacOS PostScript drivers is VERY device-dependent. The information in the PPD file associated with a printer driver instance provides critical parameters for generation of PostScript including:
Whether the printer supports color (Acrobat Distiller does)
What PostScript language level is supported (Acrobat Distiller 4.x and Acrobat Distiller 5.x are both PostScript language level 3)
Whether native TrueType support is available (Acrobat supports native TrueType as Type 42 fonts)
Available binary communications (Acrobat Distiller supports pure binary and ASCII, but NOT TCP, TBCP, or PJL)
Resident fonts (Acrobat Distiller doesn't really have resident fonts)
Available paper sizes and custom paper size availability (Acrobat Distiller supports a wide range of predefined sizes and continually variable "custom" sizes up to 200" by 200")
Margins / printable areas (for PDF and the Acrobat Distiller, there are no margins in which imaging is not permitted)
Device resolution (Acrobat Distiller can be set to any value from 72 to 4000 dpi; as a convenience, the Acrobat Distiller PPD provides a series of values for use by the driver. Since there is no inherent "resolution" of a PDF file, this parameter is used only for purposes of allowing PostScript programs that query for such a value to be satisfied and for the driver to be able to communicate this value to the operating system and/or application as required.)
Paper handling (totally irrelevant to Acrobat Distiller if input or output tray selection via "setpagedevice" is found in the PostScript stream, it is ignored by Acrobat Distiller)
Thus, if the wrong printer driver instance is selected (i.e., it isn't associated with the Acrobat Distiller PPD file) or that driver instance is improperly configured, improper PostScript will result and one or more of the symptoms described above can occur. As currently implemented, FrameMaker depending upon version will not necessarily choose the correct printer driver instance and/or correctly parameterize the print job via driver setup options. In fact, FrameMaker 5,5,6 might even try to generate PDF via calling a PCL driver, FAX driver, or even a non-PostScript inkjet printer!
DON'T USE PDFWRITER
The Acrobat PDFWriter is a relic of older versions of Acrobat. In fact, it is no longer installed by default in the "easy install" or the "typical install" of Acrobat 5. It hasn't really be updated since Acrobat 3 and only supports PDF 1.2. It is a GDI (Windows) / QuickDraw (MacOS) driver that directly generates PDF without any intermediary PostScript. Since it is not a PostScript printer driver, applications cannot pass through EPS graphics and/or PDFMark information (used for a wide variety of purposes by FrameMaker). For EPS graphics, most applications will send the low resolution TIFF (or PICT) EPS header in lieu of the PostScript text, if they send anything at all, to the driver. Forget about links, structure, or any other PDF "goodies." Expect that PDFWriter will fully "bite the dust" in the next major version of Acrobat.
SO HOW DO I GENERATE PDF FILES FROM FRAMEMAKER 6 & EARLIER?
The ONLY method that is really reliable for producing PDF files with FrameMaker 6 and earlier requires the generation of PostScript via a properly set printer driver instance associated with the Acrobat Distiller PPD and distillation of the resultant PostScript by Acrobat Distiller.
Case 1: FrameMaker and the Full Acrobat 4.05 or Acrobat 5.0x Products
PDF file from a "chapter" -- print directly to the Acrobat Distiller printer instance (Windows) or the Create Adobe PDF desktop printer (MacOS) already installed by Acrobat. If you check the "Acrobat data" option, then make sure to UNcheck the "print to file" option that gets set at the same time. As a result, the driver will automatically send the generated PostScript to the Distiller for you and delete the intermediate PostScript when done.
PDF file from a "book" -- print directly to the Acrobat Distiller printer instance with the "print to file" option checked (Windows) or the Virtual Printer desktop printer (MacOS) associated with the Distiller PPD (see details below under Case 2/MacOS). You will need to manually process the resultant PostScript file through the Distiller (or use a "watched folder" arrangement).
In both the above sub-cases, the default driver options generally will be OK, but check on paper size and communication protocol (Use pure binary, not ASCII, for optimal performance AND no CTRL-D characters under Windows. Make sure to set Level 3 only and Binary under MacOS. Font inclusion "All" for Acrobat 4.05 and "None" for Acrobat 5 under MacOS.). With Acrobat 4.05, make sure you preset the Distiller to use the joboptions you want. With Acrobat 5, you can set this on a job-by-job basis via the driver printer setup interface (or print dialog on MacOS).
Case 2: FrameMaker 6 and the Bundled Acrobat 4.05 Distiller
Windows -- Create a new printer driver instance using the latest version of the Adobe Universal PostScript Driver Installer, downloadable from Adobe's web site AND the Acrobat Distiller PPD file (located in the XTRAS subdirectory of the Distiller directory). This driver instance should be set to print to the local port named "FILE:". Name this driver instance as "Acrobat Distiller". The default driver options generally will be OK, but check on paper size and communication protocol (use pure binary, not ASCII, for optimal performance AND no CTRL-D characters). Make sure you preset the Distiller to use the joboptions you want. Print directly to this Acrobat Distiller printer instance. Make sure that the "print to file" option is checked. You will need to manually process the resultant PostScript file through the Distiller (or use a "watched folder" arrangement).
MacOS -- Install the latest version of AdobePS 8.7.x, downloadable from Adobe's web site. In FrameMaker, go to Page Setup and select the "Virtual Printer" and go to the "Virtual Printer" window pane. Select the Acrobat Distiller PPD file (located in the XTRAS subfolder of the Distiller folder). Print directly to the "Virtual Printer" (Make sure to set Level 3 only, Binary, and font inclusion "All".). Make sure you preset the Distiller to use the joboptions you want. You will need to manually process the resultant PostScript file through the Distiller (or use a "watched folder" arrangement).
Case 3: Acrobat 3
Acrobat 3 is not officially supported for the latest OS versions and I personally would no longer recommend its use for generation of PDF files given that Acrobat 5.0.5 is the current version of Acrobat.
- Dov

You're asking a lot of ancient Acrobat to work with an Office that never existed when it was made. "Just updated my office suite" is a massive change, and Window 8 didn't exist at that time either...
