Digital mockup is like playing dress-up with pretend clothes on a computer. Just like how you can put on different outfits to see what looks best on you, designers use digital mockup to try out different designs for products like clothes, packages, or websites. Instead of having to make a physical sample, they can use special software to create a pretend version on the computer. This saves time and money, and lets the designers make changes easily until they get the perfect look. Think of it like trying on different costumes to see which one makes you look the coolest. Digital mockup allows designers to try on many cool designs until they find the perfect one.
