Stormjet ICC
Stormjet ICC notes here focus on solvent and eco-solvent output that has to match from one repeat run to the next. The aim is to keep colour usable on common signage media sold in South Africa, with settings that make sense on working Stormjet machines.
Stormjet colour under production load
Stormjet ICC guidance is built around the way Stormjet printers behave in production, not in a test file. Profile use, media choice and print conditions matter when colour must stay stable across repeat jobs.
Start by separating banner, vinyl and paper, then check pass count, heater values and ink restriction before profiling. Gauteng dust can shift nozzle health, while Durban humidity changes drying and lamination timing. A profile that reads well on coated stock may fall apart on a cheaper roll if feed tension and curing are ignored.
Keep a photo of the control panel and the first acceptable chart with the job record. That small habit helps when a head clean, media change or power interruption resets something midweek. It also gives the operator a reference for the next repeat order instead of relying on memory.
What sits behind the profile
Each Stormjet ICC page points to the print mode, media family and conditions used when the chart was read. Ink limits, linearisation and a sensible total area coverage matter more than extra variants that never reach the machine. For repeat work, one dependable combination is usually the useful one.
Match Stormjet ICC with the relevant Profiles reference, the press notes in Presses, and spot checks from Swatches before changing multiple variables at once. Before freight leaves Durban or Johannesburg, compare the approved sample to the current run under the same light. ICC work starts from a test print on your usual roll, together with the RIP version you run.

Conditions that shift Stormjet output
Johannesburg shops often fight static, dust and long production days before dispatch through OR Tambo routes. Cape Town and Durban sites usually watch overnight moisture, slower drying on some vinyls and handling marks before lamination. Those differences affect when to profile and when to trust a colour match from an earlier run.
Power interruptions are not just a scheduling issue. They can alter heater stability, pause a run long enough for head maintenance, and break consistency between test charts and final panels. Record the first sellable print after any stoppage so the next check has a fixed reference.

Stormjet information worth sending
Include the media brand, width, ink set, RIP, resolution and whether the issue shows in solids, skin tones or corporate colours. Mention if the printer has had recent head changes, dampers, capping station work or a different batch of material. Those details narrow down whether the ICC is the problem or only one part of it.
Store the calibration record while the test prints, RIP settings, and media batch details are still at the machine. Keep that sheet with the job card and approved sample so the next repeat run starts from the same ink limits, pass count, and heater settings.
