Tried the mouse trail tutorial but text is rough

is there a peice of actionscript which will control the smoothness or antialias of the text? we have:

Text = “page name”;
letters = Text.split("");
letterformat = new TextFormat();
letterformat.font = “fonty”;
letterformat.align = “center”;
letterformat.color = “41898”;
letterformat.size = “11”;
spacing = 4;
speed = 3;

is theree a line of actionscript that i can add in to make the text readable?
