Profiles
Skywalker ICC
Skywalker ICC notes here focus on output stability for South African wide-format shops using Skywalker machines.
Skywalker profile use on press
Skywalker ICC notes are for shops running Skywalker machines that need colour to stay predictable on real work. Profile use, machine state and media choice all affect output on local large-format floors.
Start by matching the profile to the exact media and ink set loaded on the Skywalker. Johannesburg dust, Durban moisture, Cape Town winter damp and power interruptions can all change how a linearisation or test chart reads, so machine state matters before colour judgements do. On everyday production, heater settings, vacuum strength and pass count often matter as much as the ICC itself.
Record the first acceptable print with a phone photo and keep it with the queue sheet or RIP folder. That image helps when an operator changes media width, replaces a damper or reloads a job after a stop. Most colour complaints become easier to trace when the nozzle condition and the approved sample are stored together.
What sits with the profile
Keep Skywalker colour decisions tied to the actual machine setup, not to memory. Use one profile name, one media description and one set of RIP settings that operators can verify at the printer. A stable production routine beats collecting multiple similar presets that nobody trusts during a busy shift.
Check the related Profiles entry, the matching Presses note and the relevant Swatches reference before changing ink restriction or rendering intent. Before dispatch from Durban or Bellville, compare the approved sample against the current run under consistent light. ICC work starts from a test print on your usual roll, together with the RIP version you run.

Conditions that change Skywalker colour
Machine age, head condition and workshop environment all affect how a Skywalker profile behaves in production. A unit running in Crown Mines with heavy dust exposure may need different maintenance intervals from one closer to the coast, even on the same media. When a printer is live on paying work, separate urgent colour faults from routine profile housekeeping so the checks happen in the right order.
Coastal humidity can soften vinyl handling and change drying behaviour after printing. Inland sites often battle finer dust around encoder strips, capping stations and sensors, which can show up as colour inconsistency before a full mechanical fault appears. After load-shedding or a long stop, confirm heater recovery and nozzle health before using an old approval sheet as the benchmark.

Skywalker ICC job briefing points
Send the machine model, ink type, media name and the problem seen on the print, not just a general colour complaint. Photos of banding, oversaturation, muddy greys or weak reds help far more than broad descriptions when the issue could be profile related or mechanical.
Keep the calibration record with the printed target, RIP preset and the date the media batch was tested. When a buyer or production manager asks why the output changed, that file gives a direct reference to the profile, substrate and machine state used for the approved run.
