Too many KanBan lanes and that's only half of them...

...there is an more lean approach.

PreP – KanBan code and / or color signals. See below. This column may hold leads, opportunities, design, prepress, pending, etc for this stage.
Production – KanBan code and / or color signals; job
Opened and working on it,
Approved,
Holding for some reason, or
X completed for this stage.
Ship / Install – KanBan code and / or color signals; job
Opened and working on it,
Approved,
Holding for some reason, or
X completed for this stage.
Materials – Using a checkbox, a simple marker verifies if all materials are available for the job or not.
Production staff members are looking for “completed” signals previous to their stage so they may open the status and start on their stage.
Sales staff members are generally looking for any and all signals to see how their jobs are progressing.
Everybody knows the colors of a traffic signal in their world. This method adds the additional cool color of blue meaning the task is complete. When all stages of a row are blue, the job or item is complete and bookkeeping omits the job from the list. In many shops, only two staff members have software permissions to omit jobs from the list.
As mentioned, design what is believed to be the best but surely consider what others will want to work with as well. It is often true that "less is more."
EDITED six hours after initial post: KanBan code letters are now more clearly explained. A sage helped me with those details.
