The ROHS 721 cutting plotter (also sold as , C 721 , Jinka 721 , JK721 , or Redsail 720C ) is popular for its versatility, used for cutting vinyl for signage, decals, stickers, and garment heat transfer materials. "ROHS" typically refers to the Restriction of Hazardous Substances Directive , indicating environmental compliance, not a specific manufacturer.
Beyond simple connectivity, the driver plays a pivotal role in the precision that defines the Rohs 721’s utility. The 721 model number typically denotes a 72-centimeter (approx. 28-inch) cutting width, making it ideal for standard vinyl rolls. To utilize this width effectively, the driver manages the "page setup" and "origin point" settings. It tells the machine where the blade should start, how long the material is, and how to handle the margins. A poorly optimized driver can result in the plotter cutting off the edge of the material or misaligning the blade path by several millimeters, ruining expensive vinyl. The driver settings allow the user to fine-tune the "blade offset"—a critical parameter that adjusts how the blade turns corners. Without the driver interface to adjust these micro-measurements, the plotter would produce jagged corners and poor-quality output. for their USB connection
