Hi Team,

What settings should I use to avoid jagged edges when I save as png file.

For any image or text or if a circle or any shapes, after I save them when I view as png file.

I need to know this for my t-shirt printing. I am viewing in 'Preview' app in mac. Please advise.

 

Thanks,

Saravanan.

For test pupose I draw a circle 5.35 cm W & H at 330 ppi. I understood I should view only at 100% and not 'zoom IN' more than 100%.  Is it fine for t-shirt printing as well ?

 


I don't see jagged edges in that file. I can just about detect monitor pixels at the extremes of the circle, but those will be visible at any zoom level on non-retina screens.

 

T-shirt printing doesn't require a particularly high resolution as the fabric just can't support that sort of detail. I don't think you need to worry about an image of this size and resolution.

Don't zoom in. Be sure you view at only 100% or less. Check your final PNG size in pixels is enough for your needs.

 

Probably, you are saving far too small a PNG if you see jagged edges in Preview. This is rather awkward in Illustrator, but you need to get it right.

Thank you for reply.

 

I have zoomed in more than 100% to view the file in 'preview'.

I tried in 300 ppi as well but jagged edges occurs, even if I draw a single alphabet.

But I could see few images in net which dont have any jagged edges even if I zoom in completely.

How smooth this looks entirely depends on the resolution in pixels vs. physical size. That's just how pixel images work. Since you haven't offered any info on these things, we can't advise on what to change.

I have tried in 300 ppi resolution with different sizes. Same issue occurs and yes I have zoomed more than 100 % to view.

Test Screen Name is saying that you should not zoom in to more than 100% to preview your PNG accurately. If you do, you will of course see large pixels.

 

300 PPI is meaningless without knowing the width/height dimensions of the file. A 100 pixel wide image at 300 PPI contains the same information as one at 72 PPI, just a lot smaller.

 

Could you share the file you are testing?
