Jarrold Printing has started talks with staff to improve performance and efficiency.
Group chief executive Robert Mills said increasing imports, weakening demand and overcapacity had eroded profitability of all UK-based printers, Jarrolds included.
He said it was likely that some full-time positions would go at the Norwich-based web offset printer, but would not be drawn on a mooted figure of 80 losses.
Some of the firms older kit is being phased out and replaced by more intensive operation of new machinery.
Mills said the firm was looking to introduce four-shift, 24-hour working six days a week.
Jarrolds older equipment will not be sold off but will be kept in reserve for peak periods.
The firm has had some notable successes in the magazine market, including winning Emap Performances Mojo and Q, but has suffered from lower cost imports in the catalogue sector.
