The existing method of drying the solvent-based ink with hot air blowers did not consistently produce quality printing on the labels.
Excessive Scrap
An excessive number of labels were being scrapped due to the inconsistent quality.
Slow Line Speed
Drying the solvent-based ink with hot air blowers required line speeds of 5 feet (1.5 meters) per minute.
Solution
Heat
Two Model 4554 High Density Pyropanels (one Model 4554-A-16-12 and one Model 4554-A-16-06) mounted perpendicular to the web applied heat to dry the solvent-based ink.
Air
Optional blower kits were installed on the High Density Pyropanels to enhance the drying process.
Power Control
A Model 664F Phase Angle SCR Power Controller controlled the power to the High Density Pyropanels.
Benefits
Improved Quality
The manufacturer was able to consistently produce quality printing on the labels using the Model 4554 High Density Pyropanels to dry the solvent-based ink.
Reduced Scrap
Few labels had to be scrapped due to poor printing quality.
Increased Line Speed
Line speed was increased to 15 feet (4.6 meters) per minute.
Increased Production Output
The manufacturer was capable of producing three times as many labels by drying the solvent-based ink with the High Density Pyropanels.
