Hi there, I've been asked by a friend to design packaging for a laptop bag that he has designed, he wants a standard piece of card that wraps around the middle of the laptop bag and contains all the necessary info etc. I've read around the web that Illustrator is what's commonly used for packaging design, however, I've also seen people using Photoshop and now I'm not sure what will serve me best? I've never really done any packaging design, but what I've gathered is that the final file will have to be sent to the printers who will need to cut the card to shape & size. Will I need to provide on the file any guides for the cutting or can I just specify the canvas/file size as the precise packaging size? Thanking you in advance!
