Just want to let everybody know about the new software on this site: Inkchex.

it is a fast, accurate and on line FREE service for analysing the cmyk and spot color %'s of a print ready pdf. All you do is load the file and usually within seconds you have a result, for free of course. It can be useful for costing purposes of course. Try it anyway, it is free to use as many times as you wish. It is currently the beta version and we are looking for feedback. thanks.
