In Adobe Illustrator CC 2014 I have designed an illustration with the instructed dimension of 300 × 400 pixels, but I have also been instructed to use 96 PPI instead of 72 PPI for web publishing of this illustration. NOTE:- The company who will publish this illustration on web asked me to send the PNG in 96ppi instead of 72ppi.
I don't see how to set a custom PPI while creating a new document. However, I can change the PPI from document setup after opening the document.
But, saving the PNG at 96 PPI increases the dimension from 300 × 400 pixels to 533 × 400 pixels and saving for web downgrades the PPI from 96 to 72.
I have to submit the final PNG illustration at 96 PPI and dimension 300 × 400 pixels. How can I do this?
