Re: what is good resolution ?

Hi,
the most important thing to think of is DPI (dots per inch). A standard print needs to be 300DPI, but banners and citylights can be about 100DPI.
A0 is 9920px x 14025 in 300 DPI.
This render WILL take a while...

In my opinion, you can get away with 150 dpi with most printers.

It is not a matter of printer, but of the physical distance you have from the printed object.
If it's close, than it HAS to be 300DPI. When you have lower resolution in PX, you can blur the jpg compression artefact with lens blur and some other tricks - but it won't increase the readibility of an image. Simple as that.
Calculate (or guess) it by yourself - books and news ads are printed in 300dpi (close reading), but long range ads (banners on buildins) are 30DPI. AdWalls, Rollups (2m high, 1m wide) are 120DPI. Take your pick

Re: what is good resolution ?

Thanks Kain. I guess i'm a bit confused as well... I've researched this topic before and came across this website:


http://www.pixel2life.com/forums/ind...reen-graphics/

It says "The higher the number you can work with, the better, but it's important to know what you're printing on or you could be wasting your time. The average large plotter ink jets used to print a low number of posters for example often don't print in a DPI level higher than 150, so breaking your head with a HUGE 300 DPI poster could end up being a waste of time."


To be honest, whenever I print something in house I send it as 150 dpi. and haven't been able to notice a difference. I always try to render with the highest resolution possible, but have had a lot of problems with files crashing when I set the resolution to render at 300dpi.

Kain, do you think that the 150 limit on some printers is not accurate? This website might be terribly outdated!

Thanks!

The website isn't outdated - it is actually very helpful and straightforward. Rules for printing didn't change since then
For such a big format like A0 the 150dpi resolution should do just fine.
If I were you, I wuold try to render it at 100dpi (so 1/3 the size I've mentioned in my first post) and then print just a fragment of it on a a4 standard size paper on a home printer. I do this in Illustrator - create artboard in A0, stretch my image to fit, then place another artboard with size of A4 on a part, where thin lines are (hairs, sun lens - something like that). Then print just the second artboard and see what it looks like. I do that quite often - I have an ad agency and when we want to use an stock photo on a big poster, it is important to find cheapest size
You don't even have to render the whole image - just start the render at desired resolution and, as soon as VFB appears - stop the render and just choose a fragment of it to render
So, we're going back to the purpuose of your image and how close people will look at it?

When we've gotten things printed large scale through our printer. They usually ask us to submit the image at 1"=1' scale of the final at 300dpi. If its for a banner viewed at distance you will never notice anything below that.

Re: what is good resolution ?

I second the notion of 150dpi for the majority of the time. I think 4000-4500px wide is pretty good upper end for most work.

If you have a huge board, it normally means it is being seen at 8-10 feet away.

It is expensive, but printing on high gloss printer paper really makes a difference. Just something about shiny things...

Very well explained.

Re: what is good resolution ?

I agree 4500 px wide should be great for final renders. If you have the time to let it cook, 6000 is preferable. I would use the render to VRImg, as Fernando illustrated in his last video tutorial when rendering this size.

Re: what is good resolution ?

again its depend what type of printing you will be using. If it's using offset printing for publication, i will stick with 300dpi. But if your laser printer and colored printer then 150dpi is good enough.
