I decided to use Fireworks to design a postcard for print but am unsure as to
how well it will print. I designed it at 300dpi but when I print it some fonts
seems a bit pixelated. Could anyone advise me as to the best way to prepare the
file for a printshop? Should I export it as a TIFF? Are there export setting
that I should be aware of like 'create outlines' for text in Illustrator?

THANK you for any guidance!
