42CRC Color Registration Control
c. Transparent Web Material With Dark Opaque Mark
For this type of material, mount the control .5 (13 mm) above the web
surface and at a 10 to 15 degree angle to the perpendicular (75 to 80 from
the control to the web surface). A light colored plate or roller must be
mounted directly behind the transparent web material.
The control will see through the transparent web, sense the light colored
background providing the required contrast to the dark opaque registration
mark. See Figure 4.
