Delta E Check
Delta E Check gives print teams a measured comparison between the target colour and the sheet that came off the machine. For FastJET, Stormjet, and Skywalker users, it helps flag whether drift is coming from media, ink condition, heater settings, or the profile in use.
Measured colour checks on live output
Delta E Check gives teams a measured way to compare expected colour with printed colour. Delta E checks help keep large-format ICC work under control.
Start with a printed target on the actual vinyl, banner, paper, or film you run on site. Read the patch set with a spectro, compare the result against the reference values, and note the print mode, pass count, resolution, and heater temperatures. Gauteng dust, Durban moisture, and overnight shutdowns can all shift readings enough to matter on repeat work.
Record the first accepted sample before the job is released to production. A photo of the panel beside the measured sheet, plus the Delta E result, makes later reprints easier to check when colours look different under warehouse light, daylight, or shop lighting.
What gets checked and recorded
Use Delta E Check alongside the related profile notes before changing ink limits or rebuilding a queue preset.
- Measured difference between target and print
- Patch sheet read on the actual media
- Tolerance notes kept with machine settings
Conditions that shift Delta E
Readings can move when a printer in Jet Park behaves differently from one near the coast, even with the same file and ink set. Media storage, head maintenance, room temperature, and power interruptions all affect whether yesterday’s match still holds on the next batch.
Coastal humidity can soften the drying window and change how quickly colours settle before measurement. Inland sites often battle static and dust, which makes nozzle condition and patch cleanliness worth checking before trusting a poor Delta E result.

What to note before measuring
Write down the substrate name, RIP preset, resolution, pass mode, and heater values before you scan the chart. Also note whether the sample was read straight off the printer or after standing, because some materials shift after curing.
Store the measured sheet with the RIP settings and date while the details are still visible. That record helps when a buyer asks for written colour variance against the approved target.
