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...
Based on recent thermal processing equipment optimization, we looked to identify strengths and limitations of some thermal plate processing equipment.

A common misconception in water based ink cleaning is the thought that to be effective it would need to have a high pH and thus, be hazardous to the user or equipment. In reality there are two parts for these cleaners to be effective, pH and alkalinity. The alkalinity levels in these cleaners is what causes … Read More...
Your doctor blade and end seal are an important part of your ink metering system. Most printers would agree that the effectiveness of your doctor blade is critical to your print quality and ultimately your success with your customers. The efficiency and longevity of the doctor blade and the containment blade ultimately lead to more run time between … Read More...
Are synthetic doctor blades a viable option to replace your steel doctor blades? The answer is quite simply YES. Synthetic is safe, reliable, greatly reduces anilox scoring and increases longevity compared to many steel options. Don’t be fooled, this is a premium blade with a precision edge that is available in any tip configuration, capable … Read More...
