Monroe's ribbon cartridges produce the darkest printing black/red ribbon cartridges on the market using our exclusive True Red™ color. True Red ink is the perfect red specifically made by Monroe, and doesn't have the orange tint you see in watered down versions from other brands. Our ribbon cartridges have the highest possible inking degree, and are virtually smudge-free! To maintain the darkest print, we recommend users change their Monroe M33X ribbon cartridges after replacing 2 paper tape rolls.
