DPI in 3dsmax, wrong?

[Vizioen]

I sometimes use the print size assistant in max to have a correct ratio of my image. But I was wondering, they specifiy the resolution of the output image in DPI? Shouldn't this be PPI?

Means the same thing.

Hmmm not really, one is for printing, the other is digital. There's A LOT of discussion about it everywhere. http://99designs.com/designer-blog/2...he-difference/

Reason I'm asking is I want to know how much PPI my image needs to be to print out on an A3+ format. The printer's resolution is 4800 x 1200. Kind of confusing... :/

Usually the printing company will tell you the images needs to be at 300dpi, for example, so you simply punch that into your Photoshop document and it will tell you the res you need to render at.

Well I'm printing them inhouse on a Canon IX4000 with A3+ photopaper. Documentation states the DPI is "Up to 4800 x 1200 dpi" But how many PPI is that. Can't seem to find a solid answer. A 1000 pixels or more in width or something could lead to a few hours of rendering more. I usually render my images at 4K but maybe that won't be enough.


edit: what I think, someone correct me if I'm wrong. The printer is only as precise as its minimum DPI (in the vertical direction it's 1200) because it would be useless having more information in the vertical direction as the printer doesn't do anything with it. So let's say the max DPI of the printer is 1200 (eventhough it can print 4800 in the horizontal direction). So he can print 1200 dots per inch, if you have a 300 ppi photo, one pixel is going to be printed as 4 x 4 dots (16 dots).

To me that means the printer cant print anything more accurate than 4800 x 1200

4k is ample for A3 anyway imo

Totally forget about the 4800x1200.

1 inch is equal to 2,54cm so for example A3 at 300 dpi/ppi would be:

width: 29.7cm/2,54*300 = 3507pixels
height: 42cm/2,54*300 = 4960pixels

What does it mean then? Im intrigued now.

It means the printer is able to place 4800 DOTS per INCH in the horizontal direction and 1200 DOTS per INCH in the vertical direction. 1 DOT ≠ 1 PIXEL.

[suurland]

Just the maximum dpi the printer can do i think, but don't think anyone prints at a dpi anywhere near that. You probably can't see the difference any way.
