When ordering one-way vision film, the perforation ratio directly balances printing effect and visibility, making it the most critical factor for your project. The ratio describes the proportion of solid vinyl versus open holes, with 70/30, 60/40 and 50/50 being the most common options on the market.
The 70/30 ratio is the mainstream pick for storefront advertising and general window graphics. It has more solid surface area, delivering richer, more vibrant printed colors. It works perfectly when advertising display is the priority and indoor visibility is only secondary.
For buses, taxis and fleet windows where clear outward vision is required, 60/40 or 50/50 is a better choice. More holes allow higher light transmission, protecting driver sightlines. However, you should inform clients that the printed image will be slightly lighter than 70/30 film.
A few extra tips: always confirm local traffic regulations for vehicle window graphics. Add clear laminate for outdoor use to stop dust from blocking holes. Pulas offers one-way vision film with multiple perforation ratios, plus custom slitting services to meet your different project needs.
