UV Curing worked example
UV Ink Press Cure Speed with ink target cure dose of 75 mJ / cm²: a worked example
Suppose ink target cure dose falls to 75 mJ / cm². This page works the full calculation at that level so you can see exactly which result moves and by how much. Solve for the press speed (fpm) at which a UV ink film hits target dose, with a margin for ink film thickness and pigment loading variation.
The inputs for this scenario
- Ink target cure dose: 75 mJ / cm² (the input this scenario stresses; the baseline uses 150)
- Lamp cure-zone length: 8 in (held at the documented default)
- Measured irradiance at the web: 400 mW / cm² (held at the documented default)
Working through the calculation
- The calculation starts from the formula this tool documents: Required dwell (sec) = ink target dose ÷ measured irradiance at the web.
- Press speed works out to 213 ft / min press speed at these inputs, and this is the headline figure for the scenario.
- Required dwell works out to 0.19 sec at these inputs.
- Cure-zone length works out to 8 in at these inputs.
How this compares with the baseline
- Against the tool's baseline example, where ink target cure dose sits at 150 mJ / cm² and the headline result is 107 ft / min press speed, this scenario comes in 100% above the baseline at 213 ft / min press speed.
- It computes required dwell from dose over web irradiance, then converts the cure-zone length and that dwell into a maximum press speed in feet per minute. When the numbers land here, the stressed input is the lever to work; the walkthrough above shows exactly how much each output recovers as it climbs back toward the baseline.
