Providing Wholesale Vinyl Film Supplies to the Sign Trade Since 1987

Donna Deluca started at Penmark at it's inception in 1987. Penmark was a graphic supply company providing vinyl sign supplies, wholesale vinyl film supplies, and more. She began as a part-time secretary, but quickly took over sales, shipping, billing and whatever else was needed.


In 2000, Penmark was sold, and the name was changed to Great Lakes Graphic Supply.  Originally in Girard, Great Lakes Graphic Supply moved to its current location, and in 2004 was sold to the Deluca family, where Donna works with her son Fred everyday.

Fred DeLuca possesses an extensive knowledge of cut and digital print vinyl lines for companies such as 3M, Avery, MACtac, FDC, Vinyl EFX, and many others.


Fred provides job and media consultation, and uses his expertise to extend practical advice around media capabilities and sign making. In charge of new product development, Fred also is the instructor for the Great Lakes Graphic Supply sign Making Basics Seminar, and has been an authorized Service technician for Graphtec since 2010.
As a whole, the team at Great Lakes Graphic Supply functions as a family, and keeps that family feel within a business that has outgrown their competition. You can rely on their over 50 years of combined industry specific knowledge to ensure your vinyl sign, digital media, digital laminates, wholesale vinyl film supplies, and all other related needs are met with the utmost professionalism and know how.

"I especially enjoy the personal aspects of our business and working with my family every day.  I enjoy talking to our long time, loyal customers and hearing about their sign projects and family's achievements.  For some of those customers, I've followed their childrens' lives from when they were born, to going off to college, to getting married. I also enjoy the challenge of guiding a new customer towards the right product for their needs, and developing a personal rapport with someone totally different and new."
