Did you know that 68% of consumers believe a store’s signage is reflective of its product or service quality?
In this competitive branding landscape, signage is more than visibility — it’s about credibility, safety, and longevity. Whether you’re creating in-store visuals or outdoor billboards, choosing the right print technology and certified materials makes all the difference.
In this guide, we’ll explore:
Let’s break it down.
Before diving into printers and technologies, it’s important to understand the environments in which your graphics will live.

Indoor printing is used for applications within controlled environments — retail displays, exhibition graphics, office décor, POP materials, and wall coverings. Color precision, high resolution, and media flexibility are key for indoor graphics. Since they’re viewed up close, every detail counts.

Outdoor graphics are built to withstand sun, wind, rain, dust, and drastic temperature changes. Think billboards, hoardings, transit ads, and building wraps. The focus here is on durability, UV resistance, and scale, even at moderate resolutions.
When planning your next visual campaign, here are 5 must-consider factors:

Brands should consider indoor printing when the focus is on in-store or in-office branding, where customers engage with graphics up close. If you’re targeting environments like retail displays, corporate interiors, or event spaces — where visual clarity, fine detail, and material texture are paramount — indoor printing is the right choice. These applications demand high-resolution prints that enhance aesthetics and communicate messages effectively within controlled environments.
On the other hand, outdoor printing is ideal when your goal is high-visibility advertising targeted at on-the-go audiences. Whether it’s billboards, building wraps, or vehicle graphics, outdoor signage must withstand varying weather conditions while maintaining impact from a distance. Here, durability, UV resistance, and long-term performance become non-negotiable.
The most successful brands don’t just choose one — they strategically combine both indoor and outdoor graphics to ensure consistent branding, expanded reach, and maximum visual engagement across every customer touchpoint.
