Re: upload design for dark shirts It will be hard to see the image with white text and a transparent background (usually shown as a gray/white grid in graphics programs).
You can just design the shirt in corel draw.
Set the page background to black. Design the text as white.
Export as a PNG with tranparency and make the black background the transparent color and you can skip the photopaint step.
Just upload that transparent PNG that you export from CorelDraw.
Let me know if that helps |
