TSG Research Project:Mylar Dimensional Stability Under Excessive Dryer Heat Does excess dryer heat compromise the dimensional stability of the mylar backing. TSG feels that pushing the temperature higher could push the limits of thermal stability of the backing foil of the flexo printing plates. The recommended drying temperature is limited, as the raw polymer materials … Read More...

TSG Research Project:Flat-Top Dot Exposure Under Water General Description Is there anything else involved or critical to creating a flat top dot other than removing O2 from the exposure process? What happens when exposed under water? Since oxygen molecules are already bonded to hydrogen, we do not expect O2 inhibition (dot sharpening) to occur. Equipment, … Read More...
Scope of Test Determine if UVA lamp light energy (mW/cm2 or Joules) diminishes as temperature continues to rise outside the optimal operating parameters. According to most UV lamp manufacturers the optimal operating temperature for UVA lamps is 108ºF. At 120ºF it will diminish by 20% and at 140ºF it will diminish by 30%. This is … Read More...
