While watching the NFC Championship Game, Ken Jacobs said he was on pins and needles. And he had thousands of reasons why.

Jacobs is the operating president of Kent company Polar Graphics, which produced the T-shirts the Seahawks wore on the field after the NFC Championship Game against the San Francisco 49ers.

“It was a little bit of a heart attack,” Jacobs said of the game. “Once they pulled ahead, we had full confidence in the D and we knew they’d pull through.”

Polar Graphics’ “locker-room design” T-shirt was one of several options the Seahawks could’ve worn after the game. Jacobs said he didn’t know the players would be wearing his company’s shirts until they players put them on. While he couldn’t say the exact number of shirts Polar Graphics printed overnight after the game, the number was high enough to wait for an official outcome before printing.

“We started within a half-hour of the end of the game,” he said. “All we had to do was put the ink on the screens and all the shirts were ready to go. We had pickups beginning shortly after midnight and ready for retail at 9 a.m.”

Jacobs said Polar Graphics would be printing three different designs of Seahawks T-shirts for all major retailers in the Seattle market. Polar Graphics also printed T-shirts the last time Seattle made it to the Super Bowl in 2006, printing about 30,000 overnight after winning the NFC Title Game. While Jacobs, who joined Polar Graphics in 2008, said it was tough to compare the process this year to that of 2006, he has heard of a few differences.

“From what people are telling me, the market is so much different than 2006. The NFL has split up the market a lot more in terms of licensees. It’s not one big player necessarily controlling everything, they try to hit as many markets as they can through the best players that they can.”

As for Sunday’s game, Jacobs may have a few thousand more reasons to be on pins and needles again.

“If the Seahawks win, we’re printing for the Super Bowl,” said Jacobs.
