Method for testing writing instruments |
摘要 |
The present invention concerns a method for controlling writing instruments, in particular ball-point pens, on paper, which consists in guiding the writing instrument relative to the paper plane in a repeated movement and displacing the paper in forward direction. The movement are thus coordinated so that the line obtained forms a meandering pattern which consists in rectilinear trajectories. The invention also concerns the device for implementing said method.
