The three-year deal follows the B2B magazine printer's three-year stint as the strategic sponsor of the body, which represents the interests of small and specialist independent publishers.
Clive Foskett, chief executive of Signature Publishing and chairman of IPAC said: "It's tremendous news during this challenging period that Pensord has committed to a further three years with IPAC in its new role as our sole strategic partner."
As part of the arrangement, Pensord will work with IPAC on a number of initiatives including providing advice and guidance on magazine production cost savings and environmental issues.
"These smaller publishers need our help, and our aim is to give them as much support as is possible," said Pensord chief executive Tony Jones.
"There's never been a greater need for a sense of collective strength in the industry, and if we can help IPAC and PPA deliver that, we'll be happy."
Last year, Blackwood, South East Wales-based Pensord was a double winner at the BPIF/Printing World Excellence Awards, scooping the Company of the Year and Improved Financial Performance accolades. For information on attending this year's awards, click here.
