PNG export low quality

[livsfuchs]

Hi all,

 

I am very new to AD, just bought my license yesterday - so forgive me if I miss something obvious.

 

I created an image and exported as PNG, resolution 210x260. I was puzzled by jagged edges and pixel-effects:

69 kb

 

I tried to export with 840x1040 pixels (4x dimensions), and then resized the resulting image to 210x260 using MacOS Preview. The second path gives me slightly larger file-size, but a lot better quality at the same final resolution:

86 kb

 

What would be the best/recommended way to create a transparent PNG with optimal quality for the targeted resolution (210x260) using AD (alone, ideally)?

 

Thanks a lot,

livsfuchs

Hi livsfuchs,

 

Welcome to the forums.

 

Did you design your project at the size you wanted to export as (210x260) and when exporting did you change the Resample method?

Hello Lee D,

 

Thank you for your swift reply. Actually, the document setting is to 420x520, which is 2X the desired final resolution. However, all graphics and elements in the document are vector, so that should not matter, right? If I switch to pixel view, the quality is also inferior to the quality I got from saving a larger image and later resize externally. My guess is that small resolution export pays less attention to details somehow - maybe export with much larger size and resize to final user resolution (using interpolation) could solve this problem. That comes with some overhead memory and computation time, of course. But my guess is most users will gratefully invest this - unless they work with insane high resolution art, so maybe make this an option?

 

Any other thing I can do to help - I could try and upload the designer file?

 

Best,

livsfuchs

Very important: Have you tried all resample options?
