Hello, this is my first post here, so advance apologies if I do not ask clearly.
I am a newsletter publisher who produces his text in MS Word 2010. In addition to written text, I also insert images into my MS Word document, in the form of .png files. Then I print to Adobe PDF using Acrobat X Pro. This PDF file is what I deliver to my customers. Generally these are 5 to 15 pages in total.
My computers are clean Win7 Pro with i7 processors, plenty of ram, Nivida GeForce adapters with all updated drivers and software, and LED high quality monitors.
I notice that sometimes when I open my PDF newsletter, there is visible fidelity deterioration of the images. Basically, they look blurry and fuzzy. The text looks perfect. It's only the images that have an issue. Then other times, when opening the same PDF file, the images look just fine--perfectly crisp, and identical to how they looked when I inserted them into MS Word.
My question is--are there any obvious culprits here?
I read a lot of other PDF files on these machines. And the only time this issue occurs, is when viewing PDFs that I create myself, in the manner just outlined above.
Thank you for any insight or advice.
Addendum: Here are two screen captures of one section of my PDF newsletter. Both captures are taken from the same document. I've added color at the bottom to identify each.
Red border-- this is how the distorted image appears.
Blue border--and this is how the correct image appears.
I am desperate to determine what causes Adobe to render these image differently, at different times, for the same document. There doesn't seem to be any rhyme or reason to it.
Do you have display smoothing turned on in the preferences? What are the job settings you are using? If Std, have you tried the press or print settings.
Typically text will appear fine because they display as vector items. Bitmaps are the issue and depend on various resolutions and such. There may also be an issue that you have the display DPI set to high (try 300 or 600, not the default 1200).
Bill thank you so much for the insight.
Forgive my naivete here, since I am not terribly familiar with the settings. Here are screen caps of (I think) the relevant settings you mentioned. To be honest I am not sure which settings I am using.
So here is the rookie question: Where can I adjust, to change the settings to "press" or "pring".... to test if that works.
For creationg from within Acrobat (9.5.1 shown) for WORD the settings are in the "Adobe PDF Settings" where I have a publisher settings, not one from Adobe:
For the default Adobe PDF printer settings -- in this case under Default Settings:
In PDF Maker (for WORD and such) the settings are under the preferences. The settings allow you to select the Standard, High Quality Print, Press Quality, and several others.
There is a dpi setting in the settings file, but I was referring to the Print Quality that is found under the Layout>Advanced tab button. I set mine to 300dpi. The default is 1200dpi that often gives me problems with fine vector lines that are 1 pixel wide. 1 pixel as 300dpi is fine, but at 1200dpi it is an eye squinter and is unfortunately the default for some graphic packages. Actually I set my graphics package to 1pt, rather than 1 pixel.
Hopefully that helps some. I am just indicating what works for me, not that I fully understand the programming aspects for Acrobat. Bill
