MALVERN, Pa., Feb. 20, 2014 /PRNewswire/ -- Commercial printing businesses can now easily expand into a growing signage and display market with new wide-format color graphics printers from Ricoh Americas Corporation that employ aqueous latex ink – a more environmentally-friendly ink as compared to traditional petroleum-based inks due to its lower levels of volatile organic compounds (VOCs). The new RICOH Pro L4160 and RICOH Pro L4130 deliver high print productivity and quality as a result of technological innovations, which include the use of Ricoh piezoelectric print heads. These roll-to-roll large format printers handle media sizes up to 63.8 inches (L4160) or 54 inches (L4130) wide, and support up to seven colors in various configurations, including orange, green and white inks in addition to CMYK. The L4100 series – Ricoh's first entry into wide-format graphics – is intended to help customers expand their service offerings and increase value to their customers. An additional benefit is that the L4100 series may reduce the environmental impacts of printing through its use of aqueous latex ink and ability to operate with low power consumption. Both printers use standard 100-120v power, eliminating the need for rewiring to 220-240v. Additionally, the RICOH Pro L4160 and RICOH Pro L4130 are designed to help lower energy consumption and costs, and have the ability to use a much broader range of heat sensitive media, which make the L4100 series a smart choice for customers. The L4100 series' use of latex ink eliminates the need for special ventilation that traditional wide-format graphics printers require. But more importantly, the prints are quickly ready for finishing after exiting the system, because of a low curing temperature. Employing Ricoh's latest generation of high quality, stainless steel multiple jetting piezo inkjet heads, up to three different drop sizes are produced at once, with drops as small as four picoliters (pL). Varying drop sizes result in smoother gradations and sharper details, especially with fine lines and small fonts.
