How often do you have to stop and clean your blanket?

[mazengh]

I know it depends on the job and how much powder is required. I am interested to know the frequency, the reasons, and what can be done to lessen the stops...

Well it depends of so many factors in the printing like quality of cardboard,quality of blankets,inks,types of offset printing so it is really hard to tell the definition.

is it reasonable to stop the press every 2000 sheets and clean blankets?

This is an interesting article related to blanket cleaning. It is for web presses but could be of interest for sheetfed presses also.

I run a waterless DI press, on a glossy art paper style job, I would expect to get at least 5-7k before a blanket clean is needed, I can push it further, maybe 10k if it's not a mega quality job. I use IR drying and very low powder. On uncoated stocks, it's generally less due to paper fibre etc.

I would be slightly concerned about 2k blanket washings but I have done so, 1k was done before on a tough job.
