Hi,
We predominantly issue many of our drawings in PDF format, and what I have noticed is issues with fonts (on screen) in adobe acrobat (pro & reader). I have attached two file formats PDF and JPEG. In both files formats we have attached text which has been created in Microstation (the bottom half of text) and the other half has been created in Adobe InDesign (the top half of the text) When viewing in adobe reader the top half is a lot clearer, which is probably expected due pen tables, etc...., but you do see issues with the fonts, especially i's, l's, etc.... as a tester we created the same piece of work in a jpeg format. The results are different in that the visual appearance with the fonts seems to have disappeared.
has anybody come across this before and possibly how to rectify the problem
thanks in advance
Andrew. I don't think its hinting. That is used to render text (on screen) when it is very small. You can zoom on these PDF's so one letter fills the whole screen and the geometry is measurably different.
Yes I can see again you have height to width variations as well as variations in the kerning.
I can not reproduce this on my end. I'm also not getting the facets on Arial that you have. Perhaps old RSC files are being used? Not sure, sorry but this is getting beyond my ability to trouble shoot.
TrueType font hinting is best explanation I have. When text is text, the rendering engine can use hints in the font to draw the glyphs differently depending on the zoom level. That's going to produce the best quality. When text graphics are simply polygons, as MicroStation draws them, then those graphics do not change with the zoom level.

david,
attached is a PDF example of the arial font both bentley and ttf, and you can clearly see there are issues with the J, i, l
Andrew we have checked the acrobat settings that you mentioned and all were set accordingly
Definitely something weird here. The Letters (in MS) are about 5% shorter and a touch wider, however the kerning appears tighter.
