40 Years of Great Lakes

40 Years Behind Your Best Work

In 2027, Great Lakes Graphic Supply will celebrate 40 years in the sign-supply business. Our story began when Penmark opened in 1987. Today, we continue that business from Youngstown, Ohio, helping customers find the materials, equipment and practical guidance for their next job.

Our story

Donna DeLuca joined Penmark in 1987, working across the day-to-day needs of the business. Penmark became Great Lakes Graphic Supply in 2000, and the DeLuca family purchased the company in 2004. Originally based in Girard, the business later moved to Youngstown.

That history continues through the work we do with customers today. Whether you know the exact material you need or want help sorting through the options, we want to make the next step straightforward.

  • 1987 — Penmark opens.
  • 2000 — The business becomes Great Lakes Graphic Supply.
  • 2004 — The DeLuca family purchases the company.
  • 2027 — We celebrate 40 years of the continuing business.

What we supply today

Great Lakes Graphic Supply supplies sign shops, graphics businesses, apparel decorators and other customers with materials and equipment for their work. Our range includes sign vinyl, digital print media and laminates, heat transfer vinyl, transfer tape, substrates, banners, frames, stakes and application tools.
