Okay, so I have scoured the internet and I can't figure out how to make my comics look sharp, especially the text sharp.  If I look at a site like say "Cyanide and Happiness" on my mobile device, I can read the text and the lines in the drawings look perfect.  When I look at my webcomic the pictures looks pixelated and I can barely read the text.  And if I zoom in everything looks HORRIBLE, and the text is still not legible.

So how do all you guys make your webcomics looks so good?

I use photoshop to edit drawings and place text.  I use 300 pixels/inch resolution and scan in the drawings at 400 dpi.  The final file is saved as a .png

You'd think this would be more than enough to make a sharp, crystal clear webcomic. 

What am I doing wrong?! 

Thanks!!

Hey, thanks for the advice, but my problem doesn't lie with the initial scan, as I have posted many crystal clear comics in the past.  After the comic I posted above, I posted another which looked fine on my mobile phone, but then I posted my most recent one, and once again it looks terrible on a mobile device.  I used the same template that I used for the previous clear one.  One thing I noticed is the file sizes of the poor quality ones are smaller, but I don't understand why this is so because when I save the file in photoshop, my options for saving a png are limited to "interlace or none".  So I don't get how it would be different from one project to the next.
