Hey, I'm not sure how much you know about printing so just thought it's worth a mention; when you pick a winner you get a black and white version and a colour version of your design. With the ones I just did, I was able to pick different grades of grey/white/black using the 'working file'. If you were to just use a colour version and print it on a black and white printer, the result can be duller greys and less contrast. I'm guessing that's why we give a black and white along with the colour version. As you'll be able to see #63 I've whitened the whites and darkened the black. So moral to the story is, when you go to print your black and white invoices, for best results, use the black and white version logo. Hope this helps :o)
