manroland has introduced a Lightweight Paper Performance Package (LPPP) for its ROLAND 700 series of sheetfed presses. LPPP is described as having technical enhancements within the feeder, infeed, delivery, and antistatic equipment employed by the company’s offset presses.
LPPP is designed for printers who consistently produce work, such as mailings, inserts, and forms, on substrates that are less stable than the typical commercial printing stock of between 0.1 and 0.3 millimeters thick. Traditionally, production with lightweight papers can result in dog-eared corners, creasing, and small tears when trying to run at higher speeds.
manroland states that its LPPP testing illustrates how speeds of 15,000 sheets per hour, and above, are achievable with paper in the 60 to 60 GSM range. The company points to the following primary factors for the efficient printing of lightweight paper: Room temperature (ideal 18 until 22 °C), air humidity (ideal 55 until 60 percent), pile humidity (ideal 45 until 55 percent), pile storage (separate, not stacked), and pile acclimatization time in the pressroom (ideal at least 48 hours).
According to manroland, LPPP can increase production output by 25 percent or more, based on a higher average printing speed, while also reducing or press stoppages in the feeder or infeed area.
