In paragraph 2 of Section 2.2 of texdoc memoir, I quote
... with one page per piece of stock. In commercial printing the stock material is much larger with several pages being printed on each stock piece; the stock is then folded, cut and trimmed to form the final pages for binding. The class assumes that desktop publishing is the norm.
Is it possible to configure memoir to output large stock, multi-page per sheet PDF's, like in commercial printing?
If it is not possible to use memoir for this, my solution chain would be:
- Use
memoirordinarily, with\documentclass[showtrims]{memoir}, among other options. - Output single-page per sheet PDF.
- Use another tool to output the desired large stock, multi-page per sheet PDF. What tool is best for this?
