Sorry Vitel, I did not understand that you meant something like that.
The .pdf is with the same style as the one Augix mentioned.
For example:
http://www.jstage.jst.go.jp/article/dmj/29/4/362/_pdf
(it is open access, so no needs to worry)
JSWolf you are right and I don't expect miracles. However I believe things could be improved. Until now I use the 200% in portrait, reading one column, or the 150% in landscape mode reading again one column.
