If the information that is given to you is unclear, normalize the comunication. Build a job form, but do it multiple choise. That way everybody can easely learn to fill it out and understand it, and there will be no chance for a sales person to wright a small novell in it (in unreadable glyphs like they allways do)

. Just mark the right option.
This might prove dificult if all your jobs are very diferent from one an other, but it seams to me you company is especialised in pockets.
The form sholed have information like the number of colors, impositons style, machine it will be run, finiching equipment to be used, clients phone number... This will be usefull not just to prepress but to everybody in the plant. Only one document, all the jobs specs. 8)
