There are a few things you can do to sharpen text in Photoshop. The first is to use the Sharpen tool. This tool can be used to make the text more sharp, or to make it more blurry. The second thing you can do is use the Levels tool. This tool can be used to adjust the brightness of the text, or to change the color of the text. The last thing you can do is use the Curl tool. This tool can be used to make the text curl up or down, or to make it more curled up than it would be if it were not using the Curl tool.
