Stretching your design to the full bleed guarantees that you won't end up with white edges/borders on your printed product. Here's how you stretch a design to the full bleed:
- Click and drag the entire image to the top-left corner of the product.
Note: When the image goes over the safety margin, it will automatically jump to the edge of the printing area, where it should be to cover the whole product.
- Click the blue handle on the bottom-right corner of the image and drag it down and to the right until the whole printing area is covered by the image.
Note: you may have to drag your mouse quite far past the product's edge to get the image to cover the whole printing area.
