Sorry, Stefan. I have to agree with you. I don't see that it really made much of a difference over the original. :(

Ok... to ensure that the lines can be seen I've made the table two times, one time colored by \rowcolor (white text color or phantom text), then another time without color at the same place.
At least I can notice that the lines are shown at every magnification I tested.

I really appreciate all the effort you've put into this. Thanks. I don't suppose you can tell me how to fix the font issues (and I see they're cropping up not just in tables, but in the document in general when opened in Reader). Also (I think I mentioned this) the colors on some of the pages are like overexposed color photos (if you can remember the day before digital photography). I really think Reader has issues with the xcolor and xgraphics packages. Any ideas there? :?:

Hi Trip,

I've recently noticed some font rendering issues in acro as well (and I use quite old version). On lower magnification some letters get a little bit squashed but this is not very consistent - the same letter in a different place can look OK. And it doesn't happen for all the fonts. My wild guess would be that this has something do to with rendering optimized for screen. I don't see the same effects in e.g. Sumatra-PDF but the same font doesn't look as crisp. My only advise would be to try some other font (if this is an option) and see if that helps.

Cheers,

Tomek

Difference in how PDF renders in different readers

This is a little out of context but on-topic. It happens to me that all my documents built with LaTeX appear with a black bar on Foxit Reader right on the bottom (and the printer prints the black bar over the text).
In Acrobat Reader everything looks good. Anyone noticed the same?

Best regards

Greetings, T3. I agree, it is probably a font issue of some kind. The font settings are in the preamble of my document which can be viewed in my minimal working example. The relevant entries seem to be:

Code: Select all

Code, edit and compile here:
\usepackage{verbatim,textcomp}
\usepackage[T1]{fontenc}
\usepackage[utf8]{inputenc}
הההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההההה

I used the fontenc package to improve the overall presentation of fonts in my PDFs. They all looked pretty fuzzy before and this package helped quite a bit. If anyone can suggest another package or entry that I can put into the preamble that will help how text looks in Acrobat Reader, I would appreciate it very much.

I'm surpriced that using fontenc package affected font rendering at all. Unless of course that resulted in Type 3 -> Type 1 font substitution but I think that nowadays no distribution defaults to Type 3 bitmapped fonts any more.

If the issues you experience are related to font rendering in acrobat (which would be my guess) then I think there is nothing you can do about it other than to use different font. After all, you can't alter rendering algorithms in acrobat from the document level. You would need to change the program itself. What font do you use currently?

Cheers,

Tomek

Hi Trip,

did you test the recently released version 9? It would be interesting to know if the behaviour had been changed. I did not install it becaue there is no Linux version until now.

I'm using Reader 8 on Linux. Didn't know there was a more recent version available.

I can't really say it would "solve" my problem since I imagine, most of our customers will be using Reader 8.

I agree, using a different font could help but *ahem* how do I do that? :oops: Basically, I just open the .tex document in Kile and start typing. How do I change the font and is there a font that is known to work and play well with Adobe reader?

Also, can anyone address the color problem I'm having. Most of my graphics and the colors in my tables are much brighter and "shifted" when viewed in Reader than they should be. For instance, what *should* appear as purple ends up being a bright blue. I'm attaching a couple of example screen captures to show you the difference.

Oh duh...In Kile, click Settings -> Configure Kile -> Editor -> Fonts and Colors. Now I just have to figure out a couple of things. First, which font would render well in Reader? I can create a test document and see. Next, if I change the font and start working in an already created document, will the entire document be rendered in the new font, or will I need to completely recreate the document (which will be a huge amount of work)?
