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.
