I am not an experienced graphic designer and I guess this is quite a common question, but I haven't found a good answer. I have designed a board for a boardgame in A2 format. I would like to print this in A4 tiles for a 'mockup' or draft version. I have originally designed it in a Pages document (from which I can save in PDF of course, if that helps). As I figured out I would be somewhat limited in using this format, I have started over in Pixelmator which gives me more options regarding file formats. I use Mountain Lion and I do not have access to Photo Shop. I have downloaded a program called Posterazor but haven't got it to work (won't accept the input file). Which would be my best option to get the board printed out in A4 tiles? Thanks in advance!
