Questions re: rendering for print

Post by IslandDreamer » 31 Dec 2013, 17:32

I need to set up a variety of cameras set to print resolution and different aspect ratios (I'm rendering for different panels in a graphic novel).

At 600 dpi, my first panel is 3780x840. But if I set my scene rendering options to those dimensions, the aspect ratio value changes to 4.5 and the rendered result is squashed. If I set the aspect ratio to one, my image is square.

What am I doing wrong? Ideally, I'd like to see the camera frame dimensions masked in perspective view.

Hi, you have to check the ratio of the render AND the camera ;-)

i'm curious why you need 600 dpi?, barely anything needs more than 300 dpi on print.

It's definitely not necessary for most panels, but the extra dpi affords you the ability to zoom in closer to draw small details when you need them.

Go to 'Render Manager', check on 'override scene render options', click 'output formats'. In that ppg, disable 'maintain picture ratio'. Enter your 3780 and 840, keeping the pixel ratio 1. (Optional save preset if needed). Click 'Apply'.

Make sure all items are checked in dialog box, then click 'ok'. Viewport reflects the change, render preview shows correct square pixels.

If you want to make a smaller (faster) preview, don't change the 'output formats', just change the 'width' 3780 to eg 1/2 size, it will make the height 1/2 size automatically. If you want to change the aspect ratio, again dont change the 'output formats' rather uncheck 'lock aspect ratio' and put in the 'height' and 'width' you want.

If I were you, I'll check for the final usage of the render.
E.g. a billboard print can easily stay at 72dpi for the render, as the printers are interpolating anyway to keep the filesizes in check.

For magazine print and alike, 300 dpi is 'default' but more than enough, even for that extra 'little zoom'.
3D renders tend to be very 'crisp', even more than photo's, so you have some 'room to spare' so to speak.

Don't waste hours rendering when it's not needed ;-)
