Rainbow is now Seamless
We’ve rebranded from Rainbow Marketing, but the way we work hasn’t changed.
Ben is still leading every project, with the same hands-on approach, attention to detail, and commitment to doing things right.
Same team. Same standards. Just a fresh name.
Our History
Rainbow Marketing was founded in 1981 by Peter Heida through sheer will and determination, starting with invoices, business cards, wedding invitations, advertising specialties, cash register rolls, and ribbons.
Over the years, the business steadily grew by adding new products and services to meet customers’ needs.
In 2001, Rainbow Marketing was purchased by Ben Lunshof, who continued that growth – expanding into design services, corporate apparel, and promotional products.
Like any successful business, Rainbow Marketing has evolved with changing times.
That evolution brings us to 2026, when we proudly move forward under a new name: Seamless Print & Promo.
What Hasn’t Changed:
The same team you know and trust.
Ben and Jason will still be answering your calls and emails with the same commitment to quality, service, and reliability in Dunnville ON, and the same dedication to helping your brand look its best.
What Has changed:
Our clarity of focus.
By specializing even further in print and promotional products, we’re able to deliver even better service, expertise, and results for you.

I have been fortunate for over twenty years to be able to rely on the excellent service of Rainbow Marketing. When I approach them with a need for a marketing product, they quickly get to work seeking out the choices, suppliers, and best prices. Service is excellent as is their wealth of knowledge about what’s new.” You can’t go wrong with Rainbow Marketing!”
