The Factory That Makes Tube Roundels
Based on the Isle of Wight, A.J. have developed, manufactured and installed thousands of signs for TfL including most recently the roundels for the new Elizabeth Line.
They invited me to see how their vitreous enamel and screen printing process happen which enables them to make signs and roundels for the Tube, and the Paris Metro as well.
