Hard Rock CafeDetroit, MI

“Unisource Printing has been there for us whenever we need them. Their personalized approach gives us confidence that we will get exactly what we’re looking for, and when WE don’t know what we’re looking for they always have unique ideas based on our corporate image. You simply cannot go wrong with Unisource.”

Gordy GilletteMarketing Director Supply Den, Inc.

“From start to finish it was a real pleasure working with Carol and the team at Unisource Printing. We were very pleased with the competitive pricing, the quick turn around on our proofs and the delivery speed. It was great customer service the entire time and I would highly reccomend this company when ordering your giveaways!”

Susan BullottaDirector of Sales & Marketing

“I  just want to thank you and Ken for the wonderful work Unisource has done for me and the Michigan Key Club organization these past few years.  You have received jobs for printing, copying, pins and t-shirts.  Each time the finished job has been received on-time, correct and at a great price.  Your willingness to work with my corrections and your patience under pressure helped ease my mind about the quality and timeliness of what I received.  This past year I had a budget of $7,000 for all of the above mentioned items.  Your price came in under budget by $2,500 and helped the Michigan Key Club District to package an additional 8,900 meals for Kids Against Hunger.  This food was used to feed hungry and starving children in Michigan.”

“Thank you again for your quality work, timely completion and a great attitude and passion for what you do.”
