Hello everyone, I have attached a couple of screen shots. I use Affinity Publisher and you will see the image goes over the edge of the card into the bleed. When I print it or use print preview it leaves a border around the image. I select the correct size paper, 7 x 10 inches and borderless print. I need this for greetings cards. However, when borderless is selected it automatically changes the paper to A4 and even unticking allow printing/app to make changes doesn't stop it
