render size

[jackieteh]

what on earth is happening. Absolutley do not render at 30k.

Read this - http://www.scss.com.au/family/andrew/camera/resolution/

With an 8ft image your viewing distance is a couple of feet away - you should render at 90ppi MAX, which is a 3dsmax/photoshop resolution of 8.5k. I'd assume a 3-4ft viewing distance and render at 6k for that job.

printers do not print 1 dot of ink for every pixel, it's not possible for it to hold that much detail. you should always be half or less than the printers dpi before even getting into viewing distance.

Thanks for the article, i will read it carefully, bytheway, may i know is 90ppi MAX?

[jackieteh]

Yes, with 90ppi you are more than safe. Most print shops to whom I submit images for large prints only ask for 30-50 dpi actually !

ppi? dpi??? what is the differemce between them?

[jackieteh]

yeah, 90 is on the high to overkill end. we usually use 60 on 8-12ft prints.

Thanks, i will keep 60ppi - 90ppi in mind when i discuss with client in future

[jackieteh]

dpi/ppi, most of the advice in this thread was really bad and i wanted to emphasize that.

oh no, so which one should i follow if most advice is bad?

Perfect Resize 9 has a billboard mode

thank you, will have a look on it

I'd agree with Neilg, i wouldn't even consider rendering something of that scale at 300dpi! In years past billboard dpi was 45dpi standard (UK).

As for the differenece between ppi and dpi, probably worth reading this rather than me trying to explain it myself... http://99designs.com/designer-blog/2...he-difference/

So, the way i tend to approach stuff like this is to get the billboard or building wrap size and then find out from the printers what they intend to print at (A good printers will know what dpi should be used at various viewing distances and in some cases will have run off a few print tests at various dpi's to show the client).

For arguments sake, we'll say the area is 12ft by 8ft and the viewing distance is 60dpi. I'll then go into Photoshop and setup a new image and use the dialog box to input your sizes and your dpi (ppi) and hit enter, see image;


If you then open the image size on the new file and switch your width and height to display as pixels you should get this;


If your client/printer decides they then want it at 90dpi, change the res to 90 and you should get a new pixel size as below;


9 times out of 10 we render at 6000px on the longest edge unless otherwise requested to by the client. As Neilg said with viewing distance properly taken into account it's rare that anything higher is required.
