In short: Rebelo, AG, a Portuguese offset and digital printer founded in 1983, lost orders because customers could not picture their designs on products such as boxes and mugs. Netbase JSC built a 3D preview function with product models for the company's online store. In the first year Rebelo reported 39% revenue growth and 65% fewer visualization inquiries.

Challenge and baseline
- Customers hesitated because they could not see how a design would look on the finished product.
- Decisions took longer, conversions dropped and the service team answered many visualization questions.
- Design revisions, physical samples and reprints consumed material.
Baseline figures were not published.
Success criteria
- Customers can confirm a design on the product before ordering.
- Fewer service inquiries about how products will look.
- Fewer physical prototypes and less production waste.
