  • Asked to make a HUUUUGE 7.60 x 4 METRE banner, at 100dpi???

    My architect client has asked for a 3D render of an upcoming project, and is supplying artwork for the site hoardings (via me). The printer is making the hoarding, 7.60 x 4 metres for good visibility, but wants the image at 100dpi. Seems like overkill.

    where do I start with this??? I have the model in 3D Studio, and the first step is the render....My machine won't be happy with a 29640 x 15600 render. suppose I can do something more like 25 (33?) dpi, and blow it up later, but I still reckon my computer is going to choke. The only other way I can think of doing this is in sections...

    Anyone have experience of ENORRRRRRRRRRRMOUS images? Should I even consider the render/post at home?

    I worked it out to be about 250 Mb of image. Youch.

    Thanks for your 2 pennies.

    Does the image take up the whole banner cuz I'm coming up with almost 1.8 GIGS of image not megabytes.

    What's the viewing distance? (site hoardings = barricade covers? or building wrap?)

    Usually something billboard size (and this qualifies) is done at under 50dpi. 35dpi would probably work in this case at a 15-20foot viewing distance, even 16-25dpi if high up or on a building. Some building wraps count in Inches per Dot instead of dpi... LOL. But if the client is getting up close and personal with it, it could get dicey trying to sell it.

    The other thing too, if this is a building wrap or barricade cover it is usually done on mesh to reduce wind load. 100dpi would be a waste as much ink falls thru the holes in the mesh.

    The rendering part is gonna kill your comp.

    And rezzing up a smaller image is not likely to look sharp either.

    Tough one.

      Its going to be encapsulated (I believe) or printed onto a plastic, and fixed to a billboard type structure, maybe 3-5 metres up from the pavement. It will be up during the construction of the building, so probably a year or so, and therefore be durable and washable. I do think 100dpi is too much. 18Gb? Big youch. Must have been a factor of 10 out...

      I've only got 1.5Gof RAM, and I've tied it up before in photoshop!

      Thanks, I think...

        just as a sidenote, how big is your max file ? you might wanna try a web based renderfarm, good for the money, as long as you include it in your billing ! Or ask nicely and i could try it overnight on my dual xeon...... for a small fee [img]/DesktopModules/dotNetBB/emoticons/biggrin.gif[/img]

          They may be printing it in pieces too.

            Let's see. The Max file is 2Mb, but I wanted to do some post work on it. Maybe I could just workthe render a little more.

            I'm going to spend a bit of time rendering in portions, and I'll get back with the results. Probably lots of to come!

            Thanks guys!

              I personally know several seasoned designers that have offered advice to me and other upcoming designers. It is a thing.

              Illustrator is particularly stupid about its link situation. When Indesign opens it will at least give you a low rez image place saver and a prompt telling you the links are missing. With Illustrator,...

              Thanks for the feedback everyone! To clear up some things. I didn't study anything design related and I wasn't happy with it, that's why I quit. I did already work as graphic designer and have some work...

              I don't personally know too many seasoned designers that offer advice to other up and coming designers. Not that they aren't nice people. They just don't have the time. If they had time to deal with interns,...
