One of the edits on this page indicated:

If correctly imposed, the side-by-side pairs (6/11, 8/9 etc) should add up to 1 higher than the total page number (in this case 17).

This is misleading as it will only work in certain cases, so I have removed it for the time being. The example on the page was fine for a single section job; but consider the possibilty of the second section of a perfect bound job. A pair of pages such as 17 and 32 will add up to 49, and that trick no longer works in a straight forward fashion.

Agreed. Most imposition "rules" are more like guidelines. A press and/or prepress dept. will come up with all kinds of crazy impositions depending on the job.--drew1718 07:30, 22 September 2006 (UTC)

Non-Digital Techniques Confusing[edit]

"Digital techniques rendered stripping less necessary, but what has forced increasing numbers to abandon it completely is the introduction of "platesetters", which put pages directly onto printing plates; these plates cannot be adjusted with a sharp knife." I have no idea what that sentence means – "cannot be adjusted WITHOUT a sharp knife" might make more sense, but is still too vague for casual readers.

I would assume it means what it says: at the film stage, you can cut out and replace bits of film with a sharp knife: if you go straight from a digital computer file to an etched metal plate, it is not so easy to correct errors, without producing a new plate.-- (talk) 11:59, 7 October 2008 (UTC)

Digital Techniques[edit]

Working in CTP prepress, I think it should be stated that (in my experience) the imposition creation is not 100% automated. I have never seen a system create it's own imposition. In my application at least, I still have to manually decide the location of pages to fold properly.

I have worked in digital prepress for years in offset heatset high speed digital CTP prepress printing retail inserts. —Preceding unsigned comment added by (talk) 11:31, 18 August 2009 (UTC)
