Poor image quality in pdf for Aperture book
Can anyone tell me how to retain the quality of original images when I export to PDF for book production in Aperture?
I am trying to produce a book with 11 pages, in large soft back format. Most of the images are black and white, and all are PNGs. Individual files size are typically 12MB - 20MB, and the longer side of the images is mostly over 5000 pixels. They all look very clean and crisp full screen in Aperture, and there are no warning triangles in the page make-ups to highlight any instances of poor resolution.
I’m producing the PDF, via ‘Print’ > ‘Save as PDF’. The resulting file is 2.6MB.
Viewed in Preview, some of the images in the PDF superficially appear to be OK. Some are not - and are very indistinct. Zooming in on the images in Preview shows that very few are useable.
I produced a colour book, with larger pages last year and was very happy with both the PDF and the finished book in print. Some example file sizes from that one were: 15.3MB (3950x2633) and 9.30MB (2880x 1920).
I had expected the black and white images to work even better.
What am I doing wrong here?
I'm using Aperture 3.2.1 on a MacBook Pro running 10.6.8.
I just remade the same book - as a test - in the extra large hardback format (ie. the one I used for the previous publication, last year).
This time, the pictures are fine. The images appear to be the same quality in the PDF as the originals - much, much better. The size of the file has increased massively too > up from just 2.6MB to 52.8MB.
So does the books production function work well only with the biggest, most expensive option?
I'd really appreciate some feedback from anyone who's tried the different sizes, and preferably some brilliant ideas to make them all work equally well.

Poor image quality with save for web
It doesn't matter whether i'm exporting from Ai or Ps or whether it's CS6 or CC. I have changed the raster settings in Ai and i've also tried all optimization options with all different export file types (jpg, png, gif) at all different quality settings. It doesn't matter if I start with an ai, eps, pdf, png... the export result is always poor quality.
I have tried exporting at 300ppi and that does fix the quality issue and bloats the file size, but this way (the export route) is so time consuming since you have to resize your artwork each time as well as the artboard so that it doesn't cut off pixels. Save for web never used to have these quality issues and it also never used to cut off pixels around the edges. These workarounds prove very time consuming and produce file sizes that are not ideal.
When i first noticed this issue I was using Mavericks with CS6 and since am using Yosemite and Creative Cloud.
Steps to reproduce:
1. Create any bitmap or vector graphic in Ai or Ps, It doesn't matter whether you convert text to outlines or not
2. Save for web
3. View image in any application or browser to see poor quality and pixel trimming. Others running the same version and system are not having this issue, but I have checked many forums and found many others that do have this same issue but can't seem to find a solution.
Results:stair stepping, degradation, pixel trimming, general poor image quality
Expected results: Previously the save for web feature allowed for a decent quality imageI thought of that too so I tested on another machine with retina display and the file i saved on my machine looked bad on my machine and on the other comparable machine/display. So I sent them the original vector ai file and watched while they saved it the exact same way on their machine and the file looked fine on both of our machines/displays.
All of the settings they used appeared the same as what I used but with different results. I don't recall changing anything but does anyone know if there is some setting that could have been changed that is causing this issue? -
Poor Image quality upon PDF export
hi,
issue: images lose quality when viewed in PDFs
i've searched/read these and other forums for the past few days and have tried just about every suggestion out there in order to get better quality images in my PDFs and nothing works.. it's as if everyone is talking some theory without actually testing/proving what they're saying.
are pdfs inherently bad at handling raster images?
i have a few 800x1200 px renders (tiffs/jpgs) that i'd like to include in a PDF.. i'm using A4 landscape orientation because when viewed at full size on a 24" monitor, it's the size i'd like it to be (i'm not concerned with printing this pdf.. monitor only)
the images when view full size in the pdf are a bit smaller than viewing the original images full size however, the quality is a lot worse.
honestly, i'll try or retry your suggestions but at this point, i'm more/less looking for an explanation as to why this happens because from what i can tell, it's going to happen no matter what

Not sure what you are expecting.
well, i'm certainly expecting better quality than what i'm getting..
The jpg is contrasty and it is lower resolution than you need, but you did say that above. Which means I am not looking at what you are looking at.
The color space is srgb and the conversion from the tiff would have reduced the quality a little or a lot depending on your settings.
it doesn't matter if i use the original tiff or the jpg.. for all intents and purposes, let's forget i even have the tiff.. the jpg should look the same in the pdf (imo)
Did you print to pdf or Export? If you exported, did you use "Best" as your setting.
i've done all sort of methods.. but yeah, always at highest quality if said method allows such settings..
It has lost some contrast and is a little blurry. It looks to my eye like the degradation you get from setting the jpeg quality a little low.
well, no.. it has gone from something that is in focus to something that is out of focus.. if i open the jpg in photoshop and do a 'save as' jpg with the quality set to 3 (with 12 being best), i will get similar results as putting the jpg in a pdf.. (albeit, a different type of quality loss but just as bad)
you've seen the comparison but just in case someone else wants to look, check here:
http://homepage.mac.com/jeffhammond/Sites/imgs/origVSpdf.jpg
that's a screenshot showing the jpg on the right and the pdf output on the left (both viewed in preview)..
it's unacceptable.. but like i said earlier, i think this is an inherent aspect of pdfs and i'd settle for a decent explanation as to why it happens..
OSX has some very smart frameworks built in, which do make bitmaps displayed on screen in Cocoa apps look better than they should. Not exactly helpful if you simply want to see it unenhanced.
but still, if that's the case, why isn't osx doing the same thing to the pdf.. (and also, i highly doubt the actual quality of the image is being shown in the pdf but when i view the jpg, i'm being shown an enhanced view to the point of making an out-of-focus image being an in focus image.

Aperture Light Table - Poor image quality
I am using the Light Table function in Aperture (3.4.5.) and I had an issue with the quality of the images on it, when zoomed in or scaled to fit.
The quality of the (larger spread) images looks poor. As if I zoomed in on a thumbnail.
I was looking for a discussion on this and saw some (archived) threads. None of them solved.
However, I think I have found a workaround.
If you get this situation, you can select the image(s) on the light table and regenerate the preview.
Option-click Menu => Photos => Generate Previews
(note: if you don't use the Option key, you will get Menu => Photos => Update Previews and Aperture may say (unjust) that the preview is already up-to-date).
That solves the poor image quality look.I just remade the same book - as a test - in the extra large hardback format (ie. the one I used for the previous publication, last year).
This time, the pictures are fine. The images appear to be the same quality in the PDF as the originals - much, much better. The size of the file has increased massively too > up from just 2.6MB to 52.8MB.

HT201335 Airplay Mirror Poor Image Quality on CBS app - help?
Airplay mirror from iMac/iPad to HD TV w/Apple TV has a Poor Image Quality when watching network shows via for example the CBS.com site or the CBS app. The image looks dark, not HD at all. My internet speed/performance is obviously not the issue because Hulu, Netflix etc all come in great using Apple TV ~ sorry, not all that savvy in this department, is the poor picture down to it just being a mirror of the iMac or iPad or is there a setting or something I am missing?
You should use the Acrobat extra menu in word 2010: then edit Preferences and choose Conversion settings : High quality print
Hope it helps -
Hi everyone..
..I have been having image quality issues when using Lightroom to process raw files from a 7d mk2... They are all soft with poor clarity.....tonight in despair I tried processing them using canon's software and they are totally different..."much better"
anyone else had similar problems....AndyI have a 7D2 and have not had what I interpret as poor image quality that has anything to do with the camera.
Can you post a screenshot of what you’re seeing and what specifically you don’t like? Maybe there is something you can do differently or at least there may be an explanation for what you’re seeing.
And if you have a raw image that you wouldn’t mind sharing in a public forum, upload to http://www.dropbox.com/ then post a public share link to it in a reply, here.
In other words post a screenshot of what you see in LR, another of what you see using DPP, and a link to the raw file you’re processing. -
Really poor image quality when watching DVDs
Hi,
I was just wondering whether anybody else has experienced really poor image quality whilst watching DVDs on their MacBook? For me, the image is really grainy or blurry. I am pretty sure it cannot be the DVDs as this problem is happening with every film I watch!
Is this a common problem? What can be done (if anything) to resolve this?
Many thanks,
JohnHi John,
open system preference>display, and check if your color depth is in millions color.
try other dvd player like VLC for mac:

Poor Image Quality on Finished Project
I've seen similar questions before, but no responses. I put together a movie using still pictures, titles, and audio from iTunes using iMovie. I then export it to a .m4v format and import it into iDVD (the newest version). It looks perfect when I view it on my computer, but when I burn it (which works as it should), I get very poor image quality watching it on my TV. The images have red shadows that stretch and cover the faces. Some of the pictures are just more red than they should be, but others are just terrible. Even using the highest quality encoding, the problem persists. PLEASE HELP. Thank you.
Hi
a. make a DiskImage first and test this with Apple DVD-player.
(File menu and down "Make a DiskImage")
b. I only use streamingDV - no .m4v or like (may be it works - I don't know)

*Not knowing the origin to Your problem - General approach when in trouble is as follows.*
• Free space on internal (start-up) hard disk if it is less than 10Gb should rather have 25Gb
• Hard disk is untidy. Repair Permissions, Repair Hard disk (Apple Disc Util tool)
• Delete iDVD pref file - *or rather start a new user/account* - log into this and re-try
iDVD pref file resides. Mac Hard Disk (start-up HD)/Users/"Your account"/Library/Preferences and is named.
com.apple.iDVD.plist
While iDVD is NOT RUNNING - move this file out to desk-top.
Now restart iDVD.
• Program miss-match. iDVD 5.0.2, Mac OS X.4.11 AND QuickTime 7.5.5 - is OK - DON’T work under Leopard
• Program miss-match. iDVD 6.0.4, Mac OS X.4.11 AND QuickTime 7.5.5 - is OK (might work under Leopard)
• Program miss-match. iDVD’08 v. 7.0.1, Mac OS X.4.11 AND QuickTime 7.5.5 - is OK (might work under Leopard)
• iDVD (08) v7 Locate theme folder. Move out iDVD1, iDVD 2 and eventually iDVD4 folders to desktop - re-try
• Try a Cleaning CD/DVD that cleans the laser lens on the DVD burner/player
iDVD 6.0.4 and iDVD 7.0.1 are compatible with Mac OS X 10.5 Leopard
Last resort. from Craig. Solved the problem!! Finally!!
I deleted every iDVD application and folder from my boot drive,
emptied the trash and then installed iDVD 08 using the customize option
and I am up and running.
If You do a re-install be sure to get rid of all iDVD old parts AND then EMPTY the Trash-basket !

Poor Image Quality when Printing PDF from Office 07 using Acrobat 9 Pro Ext
Hi there,
Hoping to figure out why my images (jpegs, gifs, pngs, etc) seem to print in very poor quality when printing from Powerpoint and Word 2007?
When I actually print out the pdf onto paper, the images seem fine. The image quality is also good in Word and Excel
I did not have this problem using Office 2003 products.
Is this a common problem? I realize that the problem maybe Office related but any help or information appreciated.
ThanksIf the images' file format is PNG or TIFF you could play with the compression settings available in Acrobat's Preferences.
Edit > Preferences > select the Category "Convert to PDF".
In the"Converting To PDF" pane, select PNG or TIFF.
Then, click on the Edit Settings" button.
For either image format you could try one of the Lossless compression routines.

Very poor image quality in book Preview
I have just finished creating my first book. When I previewed it, I found that many of the images (not all) have very strange artifacts - red or white outlines, outlines, white eyes, etc. What I see in iPhoto on my screen looks great. Any thoughts?
Boot in safe mode and preview -
Before ordering your book preview it using this method - http://support.apple.com/kb/HT1040 - and save the resulting PDF for reference - the delivered book will match it.

Creating PDF from File is creating poor image quality.
When I combine files to one PDF I am receiving terrible image quality. I'm importing PNG's and I set my preferences to maximum PNG quality.

I tried to "print" my file to the Adobe CreatePDF Desktop Printer and control the image settings from there, but it keeps failing.
when you say "it keeps failing" what does this mean? Do you get any error message or messages?
The best way to create any pdf file from Microsoft Office package is to print to the pdf file as you have already tried. If this fails for any reasons you can save the file in PPT or any Office packages as PDF as long as you have the latest versions of Office - 2007, 2010, or 2013. For Office 2007 you had to download an Add-in from Microsoft website to "Save as" pdf but 2010 and 2013 are automatic.
Hope this helps. -

Hi! friends.I have bouht new E51.Its image quality taken from camera is poor.Although image resolution is high but low quality of camera is main problem.Is there any solution to improve image quality or any software to improve?
Also ringing tone is so much low.Is there bany solution to increase its ringing sound or ny software?Never mind. After testing with my android tablet I found it was the headphones. They are Bose QC 15. The original battery was running down but work great yesterday. I suspected the battery and changed it but the problem persisted which led me to blame the upgrade. I should have known better. My apple devices have been flawless. Sorry for crying wolf...

Poor image quality for uncompressed .jpg files
Hello,
I am importing in uncompressed .jpg files that I have made
smaller in Photoshop, but didn't modify compression. This is the
original format at they are stock photos. My project preferences
for jpg files are set to 100. When I import them and publish my
project, the image quality is sub- standard where areas of the
picture are blurry and fadded.
Since the images started as jpg files, recompressing them or
saving them as bmp files which Captivate likes, is not an option.
Any help is greatly appreciated.
Lisa FormanHi Rick,
I didn't notice the slide property dialog that is set to
default to Standard. This should help. thanks.
By the way, I am still having major problems with the issue I
emailed you directly last week with all the attachment files. I
know you are busy, but if you have time to revisit, I'd appreciate
it. I don' t have a solution and need to deliver next week.
