Text gets blurred when play button is clicked

I am using textMesh to create very small sized texts, similar to the size of texts used in the Clash Of Clans' user interface (like the one used to show stats about the buildings and units). Initially the text was very blurred, so I scaled down the gameobject and increased the font size & the character size, which made the text sharp enough and good looking in the scene editor window. The problem is when I click the Play button, in the Game Window the text is still blurred and not as crisp as the ones in the small texts used in games like COC and HearthStone etc. Can someone explain and help?!
