      Replacing Xenon with a LED Strobe

      This case study explores how to increase production, quality, and sustainable goals in a converter application.

      A converter was looking to replace an older Xenon bulb stroboscope on their Mark Andy 4150 press. After discussing the application, target distance, and width of the Web, I suggested the Monarch Instrument's illumiNova® 200 Fixed Mount Strobe designed for a 24″ web width with 216 LEDs and collimating spot lenses. We encourage customers to test-drive our new illumiNova™ with Monarch’s strobe demo program, and after a little paperwork, we shipped an illumiNova™ 200 for them to try out.


      Using Nova-Pro LED for Predictive Maintenance

      Monarch’s Nova-Pro LED Stroboscope/Tachometer is the right tool to stay ahead of costly problems.

      Predictive maintenance programs continue to rise in popularity as corporations, large and small, strive to increase production efficiency, reduce process downtime and operating costs, and increase overall quality and profitability.


      Practical applications for White and UV strobes in the Printing and Converting Industries.

      As Flexographic speeds increase and the use of hybrid substrates in packaging are added, on-press strobe inspections are becoming mandatory to meet the demand. Using a pure white strobe flash allows the QC inspector to virtually stop motion on a position on the press to determine its color quality, ink density, tint screens, and registration.

      How to use a Stroboscope and Laser Tachometer for speed measurement

      Using the Nova-Pro® integrated laser tachometer to synchronize strobe flash rate for instant stop motion. Benefits of using an optical tachometer with a strobe.

      Using the Monarch Strobe REPEAT and JOG/DELAY Feature for Printing and Converting

      Understanding the Repeat and Jog/Delay features for Narrow Web and Label Flexographic Printing. Viewing individual repeat patterns with a strobe when using different repeat quantities on the same sheet. How to view the first, second, and consecutive label impressions in a row using the Jog/Delay feature.

      Nova-Pro® LED Stroboscope/Laser Tachometer is two tools in one

      The Nova-Pro® has an integral laser sensor included with the 300 and 500 models (optional on the 100). This simple proprietary module can be installed in seconds or used in the remote dock for speed measurement or flash synchronization.

      Stroboscopes and Vibration Analysis

      Using a Nova-Pro® handheld stroboscope from Monarch Instrument, V-TEK Associates demonstrates resonant frequencies inherent in machine vibration analysis. By matching the rotation frequency of the MVAT6-01 the strobe flashing virtually slows or stops the motion of the rotor. This also captures the cantilever beam, which is moving in resonant harmonics with the machine vibration.

      Nova-Pro® UV LED Stroboscopes used for inspection of invisible inks

      Ultraviolet (UV) LED illuminating stroboscopes are used to inspect UV sensitive security markings made with 'invisible inks' in many Printing and Converting processes such as Pharmaceutical, Flexible Packaging, Currency, Security Documents and also for Non-destructive Testing (NDT) when combined with fluorescing penetrants.
