UV CURING MEASUREMENTS: COMPARE IRRADIANCE, DOSE, AND PROCESS RESULTS
Editable planning/verification record — Yenra
Updated: October 2, 2026
Article: https://yenra.com/uv/

Purpose: Specify a compatible measurement instrument and record the conditions needed to compare UV process measurements with product-test results.
Intended reader: Printing and coating process engineers and quality technicians

HOW TO USE
Save a working copy. Enter the actual specification, units, assumptions and evidence references in each field. Preserve original observations and record changes. Have the responsible reviewer resolve missing or conflicting requirements before release. Examples below are fictional teaching inputs, not process settings or acceptance standards.

RECORD
1. Material grade/batch, layer thickness, substrate and acceptance tests:
   ____________________________________________________________

2. Source model/identity, spectrum, settings and operating condition:
   ____________________________________________________________

3. Radiometer model/serial/band, range, calibration and condition:
   ____________________________________________________________

4. Measurement plane, height, orientation, fixture, path and cross-web position:
   ____________________________________________________________

5. Actual speed, timestamps, peak irradiance W/cm2 and exposure J/cm2:
   ____________________________________________________________

6. Saved irradiance-time profile and lamp/source identities:
   ____________________________________________________________

7. Product-test method, conditioning, individual results and acceptance:
   ____________________________________________________________

8. Approved process window, investigation triggers and reaction owner:
   ____________________________________________________________

9. Change history and revalidation decision:
   ____________________________________________________________


WORKED EXAMPLE AND LIMITS
Fictional constant profiles: 0.8 W/cm2 x 2.5 s = 2.0 J/cm2; 0.4 W/cm2 x 5 s = 2.0 J/cm2. Equal calculated exposure does not establish product equivalence. For varying profiles integrate over time; do not multiply peak by total transit time.
