Text+easing = blured text

I want to make horizontal easing that depends on stagewidth. I have made all coding and it works fine, but text in easing MC becomes sometimes slightly blured. I use pixel fonts and the start position is a round number: x.0 y.0
Is there any way to put some variable that makes corrections, like in some scrollers? Maybe it’s impossible because when someone resizes browser window it isn’t on round number, or it is?
