Controlling drive settings in a press |
| 摘要 |
In one embodiment, a method for controlling drive settings in a press for printing on a web of media. A drive is provided to receive the web from an upstream location and to transport the received web downstream of the drive at a controllable speed. The speed of the drive is sampled plural times while operating the drive in a tension control mode that varies the speed to maintain a desired tension in the web adjacent the drive. An optimal speed of the drive is calculated from the sampled speeds. The drive is operated in a constant velocity mode at the optimal speed during printing. |

1. A method for controlling drive settings in a press for printing on a web of media, comprising:
providing a drive to receive the web from an upstream location and to transport the received web downstream of the drive at a controllable speed; sampling the speed of the drive plural times while operating the drive in a tension control mode that varies the speed to maintain a desired tension in the web adjacent the drive; calculating an optimal speed of the drive from the sampled speeds; and operating the drive in a constant velocity mode at the optimal speed during printing. |
