1. My work process is explained in Screenshot 1: - I make a figure on Ai and do copy/paste it on Ps as a smart object. - I go through Ps, because smart object improves the quality of the png. - Then, I place the png on Id and export it to EPUB.   2. In Ps, resolution is 150 ppi. In uploading to Apple Books, there is a limit to each image file (5.6 MN px). It's the reason for 150 ppi. Converstion Setting on Id is in Screenshot 2.   3. I tried various ways. But they don't give me a better outcome. So far, no problem with my work process.   Hosun   Screenshot 1. Work Process Screenshot 2. Conversion Settings on Id     ... View more
