JETVARNISH 3D One 12.4.4 How to activate the Dithering function? By default, the Dithering function is disabled. Generic JVTI menu - not always related to this User Manual model If you select it, the Dithering will be activated and will change the rendering of the printed varnish. A positive effect is seen in more than 95% of the cases. Whatever the Dithering activation or not, this has no impact of the overall machine production speed. In automatic mode, the speed is a direct consequence of the JVTI thickness selection. In manual mode, operator can only reduce the print speed at a lower value than proposed by the JVTI/thickness selection. User Manual - 161 -
