Congratulations. You’ve just completed a pixel perfect app mock up and you have the nod from everyone on the team, so all that’s left is saving the tens, hundreds or maybe even thousands of production assets required. It’s probably the least interesting part of designing software, usually entailing hours of grinding. Saving images to multiple scales — as required by iOS and other platforms — adds complication to the process. However, there are ways to streamline or automate exporting.
