Have you looked at printing the current file tiled? The normal procedure in such cases to to print tiles with overlaps and marks to facilitate alignment.
Create a new document to the size required
File>Place and select the document
Repeat until all elements are placed - then print.
Except that's not going to be easy to get properly aligned and unless you use a border less printer you'll lose the page edge areas.
But cant you place many A4 next to each other and then place the artwork on the topp of all of them?
You can put up to 10 pages together in one row, but there is no way to do a grid of pages in ID, and does your printer really do edge to edge without any white space and without scaling the content (which is how most printers handle borderless, I've been told). Printing tiled is an automated process, just set the overlap and print. You can set it to 0, but having worked with tiled docs I wouldn't recommend it. Overlap allows for small trimming errors.
Oooh. Now I understand what you mean Peter :-)
I will try that out!
I think it will be ok with white spaces because I arrange the patternsheet so the lines are easy to continue in the white area.
( I make pattern sheet for prehistorical clothing as eBooks)
Thank you for your help :-)
