UV Curing Advantages Less pollution Energy efficient Very fast curing Image Source: http://www.buygreen.com/collections/no-and-low-voc-volatile-organic-compounds http://www.johnlewis.com/inspiration-and-advice/clear-information-about-our-products https://orders.idealtaxsolution.com/

Factors Affecting Curing 1. UV absorption vs. Wavelength 2. Penetration vs. Wavelength 3. Emission spectrum 4. Color / Pigments 5. Layer thickness 6. Substrate reflection

UV Curing Process UV light UV light All lacquer needs to be Not enough light … excited at the same time nothing will happen!

UV Curing Process High Activation Energy energy

Light/Photons 400W per inch Photons

Energy and Power Energy [J] = [W] x sec Logger looks at total of photons • Longer exposure -> higher count • Power [W] UV Logger • Logger looks at photons at any instance Number of photons per second per cm 2 •

How To Improve Your Curing Process? You need a tool to show you what happens inside your oven!

Are All Loggers A Useful Tool? You need information about: [W] [J] Power and Energy Individual Lamps Graphical Data Most loggers: Integrated UV meters = X + - Stationary - No dynamic data Graphical Data - Far from sheet Only give a total for the whole oven

What Does Innosen Offer? UV LOGGER MULTIBAND UV LOGGER IS310 IS315

What Does Innosen Offer? • Reading of Power in Watts [W] and Energy in Joules [J] • Readings for each individual lamp in various ovens • FREE data analysis software included • IS310 measures combined UVA+B+C • IS315 measures UVA, UVB and UVC separately • Small as a credit card • IS310 less than 6mm thick, IS315 less than 7mm thick Fast logging • Very low cost , yet with features similar to the most • expensive loggers on the market • Indication of percentage degradation per lamp

Readings For Individual Lamps Why Is This Important? 1 2 3 LAMP Same Peak = Same Power Same Area = Same Energy True? =

Graphical Data Why Is This Important? By analysing graphs you can much easier optimise your curing process! It gives you info on: • Vertical and horizontal focus • Reflector quality (dirty reflectors) • Lamp current / aging

Less Than 6mm Thick! Why Is This Important? It will enter even the smallest openings, i.e. you don’t get toasted! Light intensity Other loggers vs. 20mm 20mm thick! Distance: P = 1 / distance 2 (very approximate) Image Source: http://suptg.thisisnotatrueending.com http://www.clipartkid.com https://plot.ly

Data Analysis Examples LAMP 1 2 3 Threshold Three identical peaks - Symmetrical - Same height - Narrow and steep

Data Analysis Examples LAMP 1 2 3 Threshold Vertical Focus Issue

Data Analysis Examples LAMP 1 2 3 Threshold Dirty Reflector or Old Lamp

Data Analysis Examples LAMP 1 2 3 Threshold Wrong Reflector/Lamp Distance or Sagging Lamp

Data Analysis Examples LAMP 1 2 3 Threshold Centering Issue

Data Analysis Examples Lamps Left Center Right Lamps 3 3 Threshold 2 Threshold 1 2 Left Center Right Threshold 1 Full Analysis: Left – Centre - Right

Data Analysis Examples Lamps Left Center Right Threshold 3 2 Threshold Threshold 1 Sagging Lamp 2

Data Analysis Examples Lamps Left Center Right Threshold 3 2 Threshold Threshold 1 Sides of Lamp 2 Have Gone Black

Data Analysis Examples Lamps Left Center Right Threshold 3 2 Threshold Threshold 1 Reflector/Lamp 2 Not Parallel To Sheet

Conclusion The ideal logger should have the following qualities: Help save energy - Fast enough to Capable of providing environment- capture the power data for individual friendly peaks lamps Able to provide graphical data Able to pass that helps you identify what through the needs to be corrected in your protection slots oven image source: http://www.johnlewis.com/inspiration-and-advice/clear-information-about-our-products http://www.blackstonediscovery.com/e-discovery/early-data-analysis/

Conclusion Benefits of using Innosen’ IS310 and IS315 UV loggers: • Quick, accurate and reliable readings • Improved efficiency of curing process • Reduces lamp replacement costs • Minimize (unplanned) production downtime • Low-cost device • Easy to use interface • FREE data analysis software included

By Using A Proper UV Logger You Can: • Save on electricity costs Achieve longer lamp life • • Improve production quality • Help save the environment Image Source: http://www.buygreen.com http://www.johnlewis.com http://www.1001freedownloads.com

Other Products Helping In Curing Process IS231 Double Sheet/End Detector A fully automatic “no-touch” sensor that calibrates automatically True “Fit and Forget” IT DOESN’T HELP No operator intervention, no risk of wrong settings YOUR OVEN CURES Big thickness range (0.12-1.5mm) WELL… - IF SHEETS ARE Works on both aluminium and tinplate UNCOATED! For use on coating and printing lines, slitters and presses etc.

Other Products Helping In Curing Process IS651 Missing Lacquer Detector Protects machinery and product against problems caused by missing lacquer on sheets No need for operator adjustment IT DOESN’T HELP Self-adjusting and Self-calibrating YOUR OVEN CURES WELL… Works with all white, coloured AND CLEAR TRANSPARENT - IF PART OF A SHEET WAS NOT COATED! lacquers Protects your equipment and your reputation from expensive quality issues!

Other Products Helping In Curing Process IS415 Sheet Skew Measurement System Protects against poorly placed coating by detecting skewed (rotated) sheets at the coater/printer IT DOESN’T HELP Full protection from skewed sheets, even at high line speed YOUR OVEN CURES Faster production rates — without the risk of extra scrap WELL… - IF A SHEET IS Provides useful statistical data SKEWED AND LATER WELDED WHERE Add-on options from translation (lateral displacement) and THERE IS LACQUER! length registration (sheet feed – roller timing) Experience on modern high-speed coating lines shows that up to 1 sheet in every 2000 will skew or misalign badly as it goes through the rollers, no matter how well you control your process!
