Overnight Run
Overnight Run is aimed at unattended or lightly watched shifts where colour drift, misting, or ink starvation only shows up hours later. We use the brief to compare the first accepted print with what happened near midnight, at handover, and at the final take-up on FastJET, Stormjet, and Skywalker machines.
Night-shift colour hold
Overnight Run is for shops that push work through late and need colour to stay steady from the first board to the last roll. We use it to set up ICC profiles and cartridge notes that suit overnight production on South African large-format floors.
Night work exposes small drift that day shifts can miss, so we ask for the exact media, pass mode, heater settings, and the hour when colour started moving. Humidity on the coast, inland dust, power interruptions, and long unattended queues all change how an ICC profile behaves on FastJET, Stormjet, and Skywalker machines. Photos of the first clean output and the later problem sheets help us match cartridge notes to the way South African large-format shops actually run after hours.
Include one photo from the first stable output and another from the point where the run went off track. A short machine-side note matters during handover, especially when the operator returning in the morning must tell whether the issue was ink, media feed, or curing.
What the brief must show
The useful handover is a record of the print mode, material, cartridge positions, and the fault pattern across the shift. We look for one working setup that can hold colour across boards or rolls, instead of stacking several near-matches that only behave under supervision.
Match Overnight Run with the relevant Presses note and a Swatches check before changing multiple variables at once. Do a final nozzle test and keep the control screen values ready for the contact form, together with the machine name and the overnight fault.
- Shift notes tied to one machine
- First stable print kept as reference
SA conditions during night production
Night work around OR Tambo dispatch windows, Crown Mines workshops, and regional collections can force long continuous runs on media that behaved differently in daylight. If a FastJET, Stormjet, or Skywalker is currently carrying customer work, note which fault stops production and which issue is simply part of routine maintenance.
Cape humidity can lengthen drying and change how dense solids appear by morning. Highveld dust can affect sensors, capping areas, and the consistency of early nozzle checks after a power interruption. Record when the first acceptable print appeared after startup so the overnight pattern is not guessed from memory.

What to send with samples
Send the Overnight Run brief with print samples, photos, shift timing, and the problems that appeared during unattended runs. Keep the subject line accurate.
Pack the print sample with the mode used, RIP settings if available, and the time sequence of the problem. Add photos of banding, colour shift, edge strike, or patchy density from the same job so the overnight behaviour can be read against the physical output.
