For packaging printers, productivity is not just about speed. It is about keeping work moving consistently, efficiently, and with as few interruptions as possible.
That is especially true at J.S. McCarthy, a commercial and packaging printer founded in 1947. Today, the company serves four primary markets: food, pharmaceutical, cosmetic, and general business-to-business. Across each of those segments, pressroom efficiency plays a major role in staying competitive and profitable.
As J.S. McCarthy has continued to invest in its production capabilities, automation has become an important part of helping press teams run at maximum speed while maintaining the quality their customers expect.
Keeping Operators Focused on Production
In a high-volume packaging environment, every interruption matters.
Before implementing Sentinel ink management systems, press operators and second pressmen were manually dipping ink from cans and loading fountains by hand. That process was time-consuming and required operators to repeatedly stop what they were doing, go back to the press, check fountain levels, and reload ink as needed.
With Sentinel, that process is automated.
The system allows operators to control the ink level in the fountain and receive a clear audible alert when attention is needed. Instead of constantly checking ink manually, the press team gets a heads-up when the fountain is running low, allowing them to finish the task at hand and return to the press at the right time.
Faster Changeovers, Less Manual Handling
One of the major advantages for J.S. McCarthy is the speed and simplicity of changing ink canisters.
Rather than manually scooping ink from cans, operators can change a Sentinel canister in about 10 to 15 seconds and move on to their next task. That may sound like a small detail, but across multiple shifts, jobs, and press runs, those saved minutes add up quickly.
More importantly, it reduces the amount of manual ink handling required throughout the day.
For press teams, that means less time managing ink and more time focused on print quality, press performance, and keeping sheets moving through production.
A More Efficient Way to Keep Production Moving
For J.S. McCarthy, profitability in packaging comes down to putting as many quality sheets on the floor each day as possible. That requires reliable equipment, efficient workflows, and automation that helps operators stay focused on production.
Sentinel supports that goal by reducing one of the routine manual tasks that can slow a pressroom down. By keeping ink delivery more consistent and giving operators better control over fountain levels, the system helps prevent interruptions caused by depleted ink fountains.
J.S. McCarthy has worked with Pamarco and Sentinel for more than 20 years, and Sentinel ink management has become a standard part of how the company approaches pressroom efficiency. For their team, the value is simple: less time manually loading fountains, more time focused on quality, productivity, and keeping production moving.
