My printer uses A4 paper. I want to make a boklet where each A4 paper page comong out of the printer has two imposed portrait InDesign pages, with those two imposed portrait pages printed with the paper in Landscape mode. That is, when looking at the paper page after printing, holding it facing you in landscape, the two imposed portrait pages should have their tops at the top of the paper page (as for reading), and positioned on the paper page side-by-side (from left to right). In other words, the left (long side ) of the left imposed page should be close to the left (short) edge of the paper page, and the right (long side) of the right imposed page should be close to the right (short) edge of the paper page.
In that way I could fold the paper page along its vertical centreline, bind it along that centreline, and make an A5 booklet (A5 is half the size of A4).
However, InDesign insists in ptintong the paper page in portrait mode. That is, (to repeat the words above but amended), In other words, the left (long side ) of the left imposed page is close to the left (long) edge of the paper page, and the right (long side) of the right imposed page is close to the right (long) edge of the paper page. The result is that, with the two imposed Indesign pages stretching across the width (shorter dimension) of the paper, the two indesign pages have to be correspondingly narrow to fit acrfoss the paper page. (This wordy explanation is necessary since images are not postable on this forum.)
This results in a tall narrow booklet. I have tried specifying Landscape orientation and altered margins, etc., but it has no effect.
On Acrobat Pro, I have looked at an Adobe video of Acrobat Pro book printing. Do you have experience of it, and if so, do youthink that it would do what I want? (However, I would rather use what I have got – InDesign.)
Thanks.
