Each housing is individually marked at ambient temperature with two linear bar codes and the corresponding man-readable strings  using InfoSight’s Labelase ® technology.

Marking is accomplished in two stations :
 

At station #1 , a specially formulated white paint ( water based) patch is sprayed on the slowly rotating housing. Warm air drys this patch before the housing is transferred to station #2.

At station #2 , the patch is laser marked to black while the housing rotates. This maintains a nearly fixed depth of field. For shorter barcodes , the housing can remain stationary and the laser beam can be galvo articulated.
