User research for a digital product means talking to real users before and during your build. It tells you what problems they actually have, not what you assume they have. Most failed products skip this step. Most successful ones don’t.
UI/UX design is how a product looks and how it feels to use. UI (User Interface) covers every visual element a user sees buttons, colors, layouts, and typography. UX (User Experience) covers every interaction a user has; how easy it is to navigate, find what they need, and complete a task. Together, they decide whether your product earns a loyal user or loses them in under 10 seconds.
Prepress is the process of preparing a digital design file for commercial printing, checking resolution, colour accuracy, bleeds, fonts, and layout before the file ever reaches a press. DTP (Desktop Publishing) is where that file is built. They are inseparable: DTP creates the content, and prepress makes sure it survives the journey from screen to paper.
