Question

How to get the best quality possible, when exporting to a raster with specified pixel size?

Hello community! Sorry for such a basic question.

I need to have a 13500 х 13500px | 300ppi jpg for Society6. My project mostly has vector graphics but there is one raster image as well. 


As I understood, only size matters. So no harm to quaIlity will be done when exporting, even if 72 ppi selected.
 
But I can not simply make a 13500 x 13500px canvas & 'Export as'. As soon as the anti-aliasing option gets enabled, I start to get this famous error: "Unable to export at this resolution. Please lower the resolution and try again". Doesn't matter, if my artboard has size in inches (45 x 45), or pixels.
 
So far I've found 2 options for getting a 13500 x 13500 image with anti-aliasing enabled. Both through 'Export to screens'.
 
I set the artboard either to 3240 x 3240px, with resolution set to 300 dpi in JPG options. Or to 13500 x 13500px, with resolution set to 72 dpi in JPG options. I switch on anti-aliasing in 'Advanced settings for exported file types' in 'Export to screens'.
 
The first option gives much better result visually, bigger size too.
 
But maybe I am doing it all wrong...

If you want 13500x13500 just export at 72 ppi.

In Photoshop or (Apple Preview) change the image size to 300 ppi without resampling.

Thank you for comment. But as as I mentioned above, if I export in 72 ppi, I get a result that is worse.

Of course, more pixels will give you a better quality, but if you need 13500x13500 at 300 ppi, that's what you get.

Katarshis,

 

It is true that the final pixel x pixel size is the same.

 

What happens in your comparison if you use PNG instead of JPEG, ususally recommended when based on vector artwork?

    Thank you for an advice! PNG export looks sharper at the default view. But is oversharped, when zooming. Which is not necessarily a bad thing and can potentially boost printing result. But unfortunately I do not have an opportunity to check this right away. So I decided to stick with the best impression that I can get from observing an image on a monitor. I have a lot of thin lines in my design (https://foundation.app/collection/mlh), and JPG export with Baseline compression gives them a more smooth look.

    Amazing stock of information, thank you!


    You are welcome, Katarshis; and I for one hope that you will share your findings (also) concerning print.
