Encoders for Inkjet System
Printing equipment generally measures and generates images with resolutions measured in dots-per-inch (DPI) or pixels-per-inch. When specifying rotary encoders for certain printing applications, the disk resolution is usually correlated to print resolution.Â For example, many industrial inkjet printing systems employ a rotary encoder to track the motion of the object to be printed. This enables the print head to apply the image to a precisely controlled location on the object.
The Printing industry typically uses encoders for the following functions:
- Registration Mark TimingÂ - Offset presses
- Web TensioningÂ - Web presses, roll-stock printing
- Cut-to-LengthÂ - Binary systems, offset presses, web presses
- ConveyingÂ - Inkjet printing
- Spooling or Level WindÂ - Web presses
