I just had some Moo Business cards printed up as a trial for a new type of marketing. I print up 50 business cards, each with a different photo from the latest wedding, I keep 10 for me for giving out and give 40 to the client so they can give them to their friends. It has a photo from their wedding and my contact details on the back!

But i just got the cards back, and ive noticed the printing is super flat, particually in the black and white ones. They just look grey, not punchy or nice at all.

Is this just part of their printing style and i need to zoomp the printing up a bit, or should i convert to sRGB rather than Adobe RBG? or is it just the way they are?

We use the Moo cards for a different purpose - we print up pics from their engagement session for them to pass out at the reception with info on the back where their images will be after the wedding.

I've noticed the same thing., and use sRGB - I think it's just their printing process, and the look. Have you looked to see if there is a FAQ on their site?

just an fyi..prodpi now offers business cards that you can have up to 5 different images printed on the back. You may try that next time...that way you will still have the prodpi print quality.
