I'm definitely out of instantprint I don't understand what the problem exactly was, honestly. I sent to print a set of cards I designed (from a high resolution TIF) and the prints I got, you couldn't read the small text. I contacted to the customer service, which I must say was really helpful and kind, specially Jo. They kindly reprint the whole work after I sent again the file, this time the original photoshop file.(600pix per inch) And again, the small text looks cracked. I ended up printing all the cards myself at home, and guess what? The image looks perfect and the small text absolutely clear. So I made my client wait for nothing, I won't make the same mistake twice.
