Wondering if someone could clear up bleeds etc. for me. I've never really had to have anything printed - professionally, that is, so it's a bit new to me. I realise you need at least 3mm of bleed added to the document to print - right? And the background/images should extend to the bleed. Text and the like need to stay within the safe margins. Now, I've done a poster in Illustrator that's going to print. The art board was A3, and - before I realised you could add the bleeds etc in Illustrator, so placed it within inDesign. Document was A3, added the 3mm bleeds, stretched the poster to extend to the bleed - threw everything off a little, size-wise. I then went back to Illustrator, added 3mm bleed to that file, extended the background only - it was a solid colour - then added it back to InDesign, exported as a pdf. Now, have I done that right? Only, my problem is how do I go about it if I do something within Photoshop? Do I make my A3 canvas 3mm larger, then add to InDesign? My thinking is that if I didn't do that, then it'd be slightly pixelated due to me extending it? I dunno if I'm doing this right, I've only had a few things printed and they were for uni, and other times it was through Vista Print, but that was only for flyers etc. Also, do I need to add crop marks? Still fairly new to InDesign... and Illustrator to be fair.
