The Milwaukee-based manufacturer of signs, labels and other security products reported net income from continuing operations for the quarter ended April 30 of $17.2 million, or 33 cents per share, compared with $20.2 million, or 39 cents per share, in the same quarter a year ago. Net sales declined 6.3 percent to $290.2 million from $309.6 million, with currency translation resulting in a revenue decline that more than offset a 1.7 percent organic increase in sales.
