Printing greetings cards within Adobe Illustrator

[bigdavecox90]

Hi guys,

I'm new to all of this so wanted to ask for advice; and what better place?!

I am trying to print greetings cards on ready made 5 x 7 pre-scored card from Adobe Illustrator.

I have set my work space to 10 x 7, so naturally, I'd hope that this would print perfectly from within Illustrator on my Epson XP 345.

Am I right? Printer settings are currently set at 'Defined by Driver' and I'm working on the latest Mac software.

Any advice for getting the best quality print also? I printed something in black and white previously and it almost looked brown? To be clear, there is plenty of ink in the cartridges!

Thanks in advance,

Dave
