well, thanks for answering... smiller1 : the 2d graphic (aka photoshop) not good for what i want: A6 - 300 dpi A5 - 300 dpi A4 - 300 dpi A3 - 300 dpi if i render the bigger size in 300 dpi [ex: A3 in 300 dpi can give me a A5 in 600 dpi (without quality loss) but i need too a A4 300dpi to give me A6 600 dpi ....] in fact i 'm looking for a script wich could be easely customised to save time, because sometime, print machine Pro ask for 1200 dpi, other time 300 dpi depending weight of paper type... I hope Poser Programmers fix this in poser 6, a kind of batch rendering with size,resolution and save location options, for the night working computer. i 'm boring of theses renders you never know when end comes, just pray for computer never crash before end of render :-)) especially on windows OS...
