Let me defend the flames here a little. First I do know how to operate the 9870, very well I might say. There is not a piece of equipment in my shop that I can't operate. I started cutting my teeth in this business 15 years ago on Multi 1250's so I am aware of operating duplicator presses and their capabilities.
2 hours is not all that unrealistic for a press run from start to finish IF you figure the following:
Make the plate, prep the plate 10 minutes (we have a Xante Platemaker)
Ink up the press, mix fountain solution 10 minutes.
Mount the plate, load the first lift of paper, position copy and bring it to color 10 minutes.
Print 5000 sheets @ 7500/hr including loading and unloading paper 45 to 50 minutes.
Wash up the rollers, clean the blanket, impression cylinder and Kompac unit 15 to 20 minutes
That ranges from 90 to 100 minutes, as long as you don't need to stop to clean the blanket, clear a sheet jam that just so happens to run itself into the water unit and you need to clean that. You know the fun stuff that happens.
Now to costs.
Quote from Unlimited BT - "if you have lets say 65 pages per minute Canon it is close to $20k machine and you have about 1.5 million copies of good life in it, did you count all that? Plus on 65 ppm machine 5k run will take 75 minutes, toner is $85 for about 30,000 pages even e little less if copies have some fill..."
My click charge including toner is $0.003/ click. My Production B/W printer is almost 3 years old with over 11 million prints and still running just as strong as day 1. Did I take into account the lease charges for either the copier or the press.... no. I also did not mention that while the copier is cranking out those prints the operator is able to do other things, like cutting and folding. Try that with the offset and see how long you go before you get bit in the ass. Yes you can run a Poly plate at 10,000 impressions IF you don't have any screens. Trust me I have had a Xante for 6 years, I know its limitations.
I'll stand behind my $45 cost for the press run when you include Plate, Ink, Fountain Solution, Roller Wash, Clean Up Sheets oh and labor that pretty much is required (in my shop) to stand at the chain delivery and pull sheets to make sure the quality is to my standards.
Now if you READ my first post you will see that I say it's a necessary evil, there are things that you just can't do with a copier PERIOD. But there are things you can do with a digital device that are MUCH more cost effective than with a press.
OffsetGuy - Have you actually hired a VO Tech kid to run a press? I have, how many have you had to train until you found one that actually had the SKILLS required to make QUALITY prints from a press? I remember one who actually cleaned out the ink fountain with his fingers! Silly me I thought he would have used the ink knife.
FYI I don't let crap jobs go out my door, I will not stand for jobs that are offset, light in color, not in register... overall crap.
Will the small offset press be driven out the door by digital... No, but it is making a dent in the amount produced on them.
