render to 300DPI

[aristocratic3d]

Hi,

I cant find in 3dsmax2008 how to render a scene in on 300dpi,

Or is it enough to render in 3x resolution?

 

I am using vray.

Can anybody help?

 

Thanks

No, you don't render in DPI, you render in pixels. Multipy 300 by the desired print size in inches to get the pixel dimensions.

Do you mean that If I need a printed size of 1500pix resolution then I have to render in 4500pix to get 300DPI print?

 

Thanks

I now have no idea what you're talking about. Here's the deal. PPI is pixels per inch. DPI is a description of a printer that has nothing to do with this but people misuse the term. So if you want a 300 PPI image, just saying "I want a 300 PPI image" means nothing at all unless you know the print size, in inches. Pixels per inch, see? Multiply 300 PPI by the print size in inches to get the render size in pixels and that's the setting that goes into the renderer.

The thing is, I produced some images for my client's website in 1500x800 resolution. Now he says that he need those image for product catalog print. So this time he needs 300DPI. I know that dpi and pixle per inches is just two different unit of measurement.

 

But I dont understand what should I deliver him by now! I gave him 1500x800 pix/inch resolution image. But now what is he looking for by that 300DPI? what can do for him?

Should I resend him those images in 4500x2400pix/inch resolution?

 

Thank you so much.

If he wants a 1500x800 image, and he wants 300 PPI, he wants to make a 5 inch x 2.67 inch print. If that's not the case, he hasn't provided you enough information - he must tell you the print size, in addition to saying 300 PPI.

[aristocratic3d]

He said DPI (dot per pixel). not PPI (pixel per inch).

BTW, I will ask him for more info.

 

Thank you very much for the help.

DPI (or PPI) is just like font size. Increasing or decreasing it might increase or decrease the number of pages a document takes up, but there's still just as much writing there. Saying they want a 300dpi image without giving you the physical size is like saying they want a Font 12 document but not telling you how much to write.

[aristocratic3d]

The physical dimension of this print is - 5.83" x 8.27".

print guy says he cant work with the resolution of 1500x800 for the print. and informed that they are 72 dpi. But how should I render in 300 dpi then. is 4500x2400 resolution is enough while I the print size will be 5.83" x 8.27".

 

Thanks all

Hi all,

Dimas said the right thing here is the thing I need.

But I still have question as I will go to render multiframe. so should I click on render scene dialog? will I get 300 dpi then also?

 

Thanks again

Reread andrews posts, essentially:

 

5.83" * 300dpi = 1749 pixels minimum

8.27" * 300dpi = 2481 pixels minimum

 

to save time in the long run, i'd render larger if you have the resources.

 

4500x2400 is Larger than the above 300dpi requirement AT THE REQUIRED PRINTED SIZE, but it is a good rule of thumb to render/work larger if you have the resources to do so for when they ask for larger yet prints.

[AJLynn]

Just multiply the DPI/PPI by the inches to get the pixels. This is really, really easy.

this is good advice... always over shoot the target if you have time and resources available to do so.

 

Also, if you are having a really hard time with the calculations, try this:

 

1. open Photoshop

 

2. create a new document at the required print size. Make sure it is 300 DPI

 

3. ctrl + shift + I ---> you will be able to see the documents dimensions, both in inches/mm/whatever and the resolution in pixels.

lol, these PPI/DPI threads always cheer me up.

they make me very very very depressive......
