Speaking of sound, I can now tell you if the many presses are running as they should because I can hear the different machines as they print away. I guess this helps me to keep them up and running correctly. Each one makes a different sound and I can tell if the ink needs to be replaced and if there is an issue with the paper as it glides through each one. Life for me has been made easy because someone gave me a change to prove myself. Hard work, learning different ways to get the job completed, as of course the love of printing has made who I am today. From time to time I just wonder if folks will be reading news papers and books in the future. as for now, I will keep smelling the ink and turning out the printed word.
