Make ready question/survey

[offsetflexo]

Doing a little survey:If you are printing 2500 sheets on a digital press (I know, may be pushing the limits), on a stock that you may have not used before (perhaps an unusual stock like pressure sensitive or synthetic poly) how much stock over 2500 sheets would you require? If you answer please include the press you are referring to. Thanks

I don't think 2500 is "pushing it" on a digital press, unless, you're not really running on a digital press, but rather, a piece of office equipment. Last summer, we printed 180,000 24-page variable booklets. Unlike offset, we like to have left-over stock of every job we print, if, for nothing else, but samples. But the answer lies in how you buy your stock. You're certainly going to use "some" for set-up, so, you will have to order more than 2,500. If it comes 1,000 to the case, I'd order 3 cases. If it comes 500 to the case (or ream) I'd order 6 reams, etc.
BTW we are running Xerox DocuColor 8000's and 8002's.

Like MailGuru I don't think 2500 is even getting close to pushing it on a digital press. We to have an 8000AP and runs like that are the norm. I also agree with get extra paper either by the ream or case (whichever is needed) to make sure you have plenty. Inevitably you will have issues down the line with finishing that will require extras. Plus keeping samples for you to have is a good idea.

I'm working on a 20,000 11x17 digital run, I will order 22,000 sheets.

Edit: This will be ran on a x800, possibly supplemented by a x700.

What about the substrate being pressure sensitive/or synthetic poly? there is a lot of static involved on these.

Any bad prints with toner and ink blobs due to static need to be taken out of the pres run for the client. They want perfect looking print samples for the substrate they are selling.


I have heard 500 sheets of make ready CAN BE NEEDED on a 2500 sheet run.
Just wanted to confirm this
(nexpress 3000)

We've run both pressure-sensitive and syn poly with virtually no static or "ink blobs". Even though 500 extra sheets on a 2500 run may seem like overkill, (a full 20% overage), on small volumes, it's about what most are going to tell you. When your volume increases in to the tens of thousands, we figure 2 to 3 percent for spoilage.
Like Craig, we're running Xerox 8000AP's and 8002's. The 8002's have a built-in ACQS (Automated Color Quality System) that helps to maintain color consistency throughout large print runs which helps to decrease spoilage.

The only static issues we have is with Syn Poly and that is AFTER they are imaged. Forget about jogging!!
