Nantian PR9 Ribbon Cartridge products have applied high quality indelible inks which conform to European standards, with a life span of 7 million characters and a maximum of 10 million characters is now available. The ribbon cartridges are 341 mm in length, 69 mm in width and 12 mm in thickness, which have been optimized to enable the best transmission of ribbon fabrics and the lower rate of ribbon jam.The inks applied were poisonless, skin-insensitive and metamorphic after ECCB1_OECD 401. 402. 404. 405 test. The fabrics used on PR9 ribbons are in good quality and manufactured with unique technology, which can reach a tensile resistance of 8N/MN or above. Higher tensile resistance, longer life span will be guaranteed. Besides high quality fabrics, appropriate amount of ink and cycling speed is a must. Exquisite ink, appropriate cycling speed has reduced the falling and damage of the needle guide board on print head, which lead to less abrasion of the printing needles.Features:*Environment friendly ink *High quality fabrics *High tensile resistance *Appropriate ink contents and cycling speed *Scientific structure *Less abrasion
