Why not make a PDF for the printer and specify the scaling amount (70.5%)?
I can't do that, Michael Witherell, because I can't let the print shop responsible for it.
Besides, I have to send it to the board of directors in A5 size.
However, some documents have to be in A4 size, depending on each situation.
Thanks for your suggestion, anyway!
InDesign does a very good job of placing PDF files, letting you rescale them, and creating a new PDF.
Place the A4 file and scale it down in InDesign, and save a scaled PDF. Show the PDF as a proof to your board at A5 size and send the scaled PDF to the printer.
Steve, thanks for the suggestion. I've tried to open the PDF file but it didn't work. InDesign displayed a warning saying some plugin was missing or it would have to be opened in another software.
Another thing: I found an option in InDesign for rescaling pages, named "Page Tool" (SHIFT + P).
There is an option "Liquid Page Rule". I would like to know if it would be useful for what I've been looking for.
I've tried and I was able to resize pages, but I don't know what it is used for... Thanks again!
Use Steve's suggestion. Don't attempt to Open it. You must Place it into another InDesign document.
You can't open PDFs in InDesign.
What you can do, is to place the PDF/X-4, which is exported from the original INDD or the INDD itself.
Why do not scale the layout and the page format directly from the ID "A4" file [tested].
Of course, it truly depends on the way the layout has been done [tab., anchoring, …] but it can be done softly with small and quick layout corrections!
Eg, all the layout is done with fonts sizes 9/11/12/17 points on several different para/char styles and you need to apply a 66%. You can modify all the styles in 1 click and ever have "pure" styles!
I would do it with QuickResize: http://www.id-extras.com/products/quickresize, which is the quickest, easiest and most reliable way to rescale an InDesign document.
However, if you do not want to pay for a solution, or if you're not allowed to use scripts as you state initially, I think it is worth trying InDesign's built-in scaling feature, as Obi-wan suggests. Theoretically, this should do exactly what you want -- rescale your document to any new size. In practice, though, it doesn't work so well, and, depending on the elements in the document, you may need to do many, slow layout corrections. Worth trying though.
Sorry, personally, I'd rather pay $ ... for the job!
I don't do advertising for QuickResize, but it truly looks like!
Even if I hugely appreciate all your work [as you know!], everyone here will forgive me!
Thanks, Obi-wan Kenobi. That was exactly what I did. I have to keep both templates: one in A4 and other in A5 sizes.
Thus, this was the best thing to do: changing sizes and scaling layout I was able to have what I wanted.
Thanks for your help! Thank you all!
