Lab Day measurement points
Lab Day specs give the technical detail behind Lab Day. Review the profile-related checks used during test and measurement work.
Lab Day specs set out the readings and machine conditions recorded during profile testing for FastJET, Stormjet, and Skywalker units. The page is used when checking ink limits, linearisation behaviour, and whether the target was measured under stable shop conditions in South Africa.
Before any patch chart is printed, confirm the media code, pass mode, heater values, and RIP settings used for the run. Dust on inland sites and higher moisture near Durban can both skew a reading set, so the notes lock down what was in place on the day.
Recorded values on test day
Expect figures tied to the actual measurement session rather than generic printer data. That includes the profile name, target type, resolution used, and the final checks that showed whether the output was fit to save as a working ICC set.
Use this sheet with the related Profiles record, the matching Presses note, and any Swatches comparison before making changes in production.
- Ink limits logged per media
- Resolution and pass mode captured
- Machine photo linked to test notes
Conditions affecting SA readings
Coastal workshops often need closer attention to drying and re-measure timing, while Highveld shops may need extra cleaning before a chart is trustworthy. Load-shedding also matters, because a restarted printer can print a different first chart from one held on stable power.

Notes to capture during Lab Day
Record the media brand, RIP preset, heater temperatures, vacuum level, and any nozzle loss seen before the target was printed. Include what failed earlier, especially if banding, colour drift, or uneven solids led to the Lab Day check.
Store the measurement sheet with the calibration entry and the printed target ID while the settings are still visible on the machine. When a buyer or operator asks why a profile was approved, those figures provide the technical trail behind the result.
