Really, this should be pretty elementary stuff for anyone working with a printer, and if not, then the printer should have enough savvy to help out. Then give everyone in the print office a pink slip :ba. If the print office cannot change that into 300dpi without resizing the image then … If you need bleed then calculate that in. (Make dimension in pixels fixed) Save it and the header will say 300dpi. If the print office cannot change that into 300dpi without resizing the image then open GIMP or Photoshop and simply enter 300dpi in the appropritate place and make sure that your image is not recalculated. The resulting png will be that size and will still have 96dpi set in its header as that is what blender writes into each file it saves. Now you render your result to 6300*8190pixels. So you calculate your output resolution as pointed out above 21 300 = 6300 and 29,7300=8910. Since your delivery is 300dpis (= 300 dots per inches) 1 dot = 1 pixel. A4 = 21,0 × 29,7 (cm)įor ease of calculation lets assume we are not giving dpi (=dots per inch) but dpc (=dots per cm) The output is going to be a A4 sized paper. As chipmasque has pointed out you need to provide a certain amount of pixels in order to get a certain size of printout.Į.g.: You are supposed to deliver a printable solution of one of your renders. PNG is never vector based it is pixel based and the dpi in the file is simply a suggestion for the printing software and can usually be altered by it.
