This was a friend, who was some unfortunate designer’s client a while back:
Client: Hey, I just downloaded Photoshop. How do I save jpegs as .eps in good quality? We need to get our company clothes printed ASAP and the printer doesn’t accept jpeg.
Me: Don’t you have your logo in vector format?
Client: The old one’s vectorized, but we only have small jpegs of the new one. Also, I made some adjustments. Photoshop lets me save as .eps, but it looks kind of bad.
Me: You can’t do that. Why not contact the agency that made the logo?
Client: That was a few months ago, and we haven’t exactly paid them yet.
