Hi one of client has requested a 8 feet x 6 feet final render size,
and will use the final image for digital print, he has mention without pixelated print,
did anyone know what is the size should set in 3ds max to match his requirement?

thank you

find out what DPI the printer can print at and then you’ll have your answer.

it depends how far the board is going to be from the people… you don’t have to go full resolution if it is far away.
besides that you could render it out 1/4 of the full resolution and use plugins to scale it up.

www.alienskin.com they have blowup to do that

there are several companies with similar products

Perfect Resize 9 is the absolute best for sampling up IMO.

Most printers use around 300 dpi. A simple calculation:
8 Feet * 12 (inch) * 300 (dpi) =28800 px
6 Feet * 12 (Inch) * 300 (dpi) = 21600 px
As mentioned, viewing distance matters, and you can probably get away with less.

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

Read this - Resolution - Digicam - Andrew Gregory's Web Pages

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.

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 !

8

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

Calm down, no-one is suggesting that. Everyone pointed out that viewing distance is important. I just explained how to do dpi calculations.

10

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

11

this is the CGI version of kitchen nightmare …you missed “this is disgusting”.

Perfect Resize 9 has a billboard mode

13

my client himself also don’t know the DPI

14

beside of the DPI, my client also don’t know how far is the board from people, he just mention he wants the final render to be print out without pixelated

15

what say if my client don’t know the distance?

16

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

17

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

18

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

19

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

thank you, will have a look on it
