i’m new to this so need some advice, i have generated an image using AI. i then use the website imgonline.com.ua i resized the image from 810x1440 to 7200x9600 (AR 3:4) at 300 DPI. if i was to get a sale in the size 3:4 is this file okay to send to print shrimp or do i need to do anything else to make sure the quality is still good when printing.
