Remove black border from all-white image?

[adrenaline]

Hi all,

I'm a Photoshop beginner, and I am having some troubles. I have created a solid white image on a "transparent background." The problem is it comes with a small black border around the image. How can I remove it? I'm hoping to put it on a t-shirt - almost like it's screened. I've attached a copy of the gif.
Thank you.

Try.... MENU > LAYER > MATTING .... use either Defringe or Remove Black Matte..... If it has some effect of diminishing the border, you may have to apply it a second time.

Hope this helps.

Convert to RGB, go to Select|Color Range and pick the white area and bring the Fuzziness slider all the way down.
Use Refine Edge if you need to.
Invert the selecting and press delete.

Save as a gif or png.
