I'm also thinking of starting a wedding invitation business. I've got the design skills, I know that much - my question is on the printing process. I've got 2 years of graphic design schooling, I'm about to get a career diploma in Desktop Publishing, and in all my studies I haven't found anything that clearly explains it. For example, if I designed an invitation in InDesign, what would be the best way to present it to the printer if I wanted it printed in offset lithography? Do I submit it with color separations or do they do that themselves? And can someone please tell me the difference between a printer and a service bureau??? I'm sorry if my questions are stupid, but there doesn't seem to be any way for me to get printing experience in my area and I just cannot find a clear explanation of the printing process ANYWHERE. Thanks!
