Shows a black border around the picture.

Hi, I want to have some t-shirts printed. I imported a picture, the background of the picture is black. After viewing the preview, the tshirt doesn't blend in with the black tshirt. It shows a black border.

I want the image to blend in with the black t-shirts. Any idea how to fix this?

If you haven't already, try saving and uploading as a transparent .png file.

Hi, I tried what you suggested. I removed the background and saved the file in PNG. This didn't work, it still shows a black border.

If you are referring to the black between the white base shape and the white linear outline, try removing the white linear outline.

If you're referring to the white stroke around the picture, I would like to have that has part of the image. It shouldn't show a black border because of the white stroke around the picture.

Hope this helps show what I am trying to explain.
If it is a transparent png, then changing the color of the shirt, for a rough example, to a blue, or some other dark color besides black, should look something like this example:
You still get to keep the white outline. (except on a white shirt, then it's white on white)

I see what you're saying.

Not to sound like a pain in the ass, I really wanted to print on black tshirt. Sorry for sounding like Im stubborn

you can print it on a black shirt, but you will get what you already have gotten.
where you see black, that is the transp with the shirt showing thru.
same when you look at the blue ex ,the blue is the transp of the blue bg/shirt.see transp when on black? look again at the blue,

You’ll need to remove the black background color. It will always be noticeable, no matter how closely it matches the tee. The only color you want is the white. The background will need to be transparent. It will be hard to see until you put it on a dark colored tee, then it will look perfect.

I did, I removed the black background then saved it as PNG. It made no difference unfortunately.
