I’ve designed something in Photoshop and now am ready to send it to the printing company. The company requires this:

[LIST]  
[_] **Must include composite color proofs; separated lasers preferred as well**  
[_]Supply printout of the contents of the disk  
[_]Photoshop files saved as CMYK  
[_]If using Quark EPS files, supply original Quark files  
[_]Supply all document fonts including fonts for embedded graphics  
[_]No font stylization  
[_]Please notify in advance if using Multiple Master Fonts  
[_]Minimal resolution 300 pixels per inch. Scaling maximum 125 percent  
[/LIST]

I understand all but the first point. I did a Google search for it + Photosohp. It didn’t return any tutorials. What exactly are “composite color proofs” and “separated lasers”? Is this even done within Photoshop or do I need another tool?
