Firstly, I recommend you set the page as Portrait. You can do this from the View menu by using the Rotate page option:

After that, rotate the objects (names) by using the Object > Rotate option:

In this way you will be able to make sure that there is enough space between objects. Set the names across using the Move option (
) and then send them to the cutter. If you have issue, use the Contact Us page to get in touch with the support team.
