need help figuring out large format render resolution

[J.C]

Hi, I was asked to re render some work that will be printed on a 10X4m (33'X13') billboard. I'd like some advice on what is the lowest posible (acceptable) render resolution I'd have to consider . Thanks in advance.

 

Regards,

JC

should have searched prior to asking, thanks for the links

went for 11811X4724 at 300 DPI for the 10X4m Print. so I quoted according to that, hope I didn't screw up.

Good luck trying to output that.

A bit of help instead of the sarcasm would have been better if you took the time to reply. Anyways that reply seems to confirm that in fact, I screwed up. I went with what a friend of mine who works at a local print shop told me, but apparently he got me more confused.

Banners of that size never require 300 PPI Resolution. Normal would be something like 70-120 PPI. I would go and ask the guy who will print it what resolution he wants.

that makes no sense. DPI is quoted together with physical dimensions, not pixels dimensions. DPI is pixels.

 

ie, 5 meters @ 300 DPI equals nearly 60 thousand pixels wide. it's a tad confusing if ur new to it.

 

for your job, you'd probably get away with rendering your long side to 10000 pixels. What Florian says is true, but even those DPI figures might be a bit optomistic for a banner that size.

 

10 thousand pixels equates to around 25 DPI. sounds low, but plenty good enough for something that sized. but of course, if you can render larger then do so.

I'm with strat. 20-30 DPI is likely appropriate. If the client is being silly asking for 11M @ 300 DPI, render it lower and then balloon it in PS. I dont think any print shop will use an image that size.

Sorry for the late reply (family trouble)

 

I got the call from the client who had already received the 11811X4724 at 300 DPI quote. Told him I had mistyped an addtional zero and that it would be 11811X4724 at 30 DPI. It was extremely urgent for him to get my quote that day so I didn't have enough time to do proper research.

they actually asked me for a 10X4m at 300 DPI. I thought they didn't ask me right (being new to this) so yes, if I have had any knowledge of what you are saying it would have been easier I think.

 

So I'll go with strats advice on this, 10k on the long side and a small resize to 11.8k

 

Greatly appreciated advice, thank you all.

11811X4724 at 300 PPI is exactly the same as 11811X4724 at 30 PPI. So your client is getting exactly the same thing. You should read up on that stuff here:

Not if the first dimentions are in mm ie 11811mmX4724mm. at 30dpi.

 

I have had the same request, fortunatly I know someone who works in large scale printing and asked for a bit of advice....

 

Just need to educate the client a bit...

 

Why are pixels measured in inches anyway... anybody know?

The way I understood it he meant pixel.

Yes, pixels.

I read the wikipedia link (2 to go) I believe I got it now. My statement to the client should have been -10x4m at 30 PPI- as Strat mentioned earlier (PHYSICAL DIMENTION @ "X" DPI).

 

Thank you, I'm about to press render on my first render at this kind of resolution with GI and all.......... wish me luck.

Sorry i didn't mean to be rude. You seemed confident that you can output into that resolution. I've never done it. The only thing i know is how hard it is to output a 4000x wide image, i figured you might have different experience since you came up with such a large resolution out of the bloom.

......... wish me luck.

Hey, i wished you good luck a couple of days ago, what's with the attitude now
