Start with the repeat job and the media in front of you
Before changing any settings, compare the current output with the approved sample or the previous good run. Look at the same artwork on the same media, under the same light, and if possible from the same batch of material. A job can look fine on matte vinyl and still run off on gloss, textile or laminated stock.
Check the basics first: media type, ink set, print mode, pass count and any operator changes made since the last order. If the client is in Randburg, Pretoria or Durban and wants the same colour as last month, you need to rule out material changes before touching the RIP.
- Use the same media roll or note the batch number.
- Confirm the print preset used for the original job.
- Check whether a different cutter, heater or finishing step was added.
- Compare in daylight or a neutral viewing area, not under mixed office lighting.
Check the file, profile and output intent
Colour drift often starts in the artwork file. A file exported with the wrong colour space, missing profile or a changed spot colour will not print the same as the approved version. In a busy shop, that often shows up after a staff handover or when a designer saves over an old file.
We guide you through the file path from artwork to RIP so you can see where the shift begins. That includes checking whether the artwork was created in CMYK, whether embedded profiles were preserved, and whether spot colours are being converted the same way on every job.
- Confirm the artwork version matches the client approval.
- Check if the file carries an embedded profile or a custom spot colour.
- Review the RIP colour intent and any conversion rules.
- Make sure the same file is being used for reprints, not a rebuilt version.
Set one colour workflow for the whole shop
If one operator prints from a default preset and another makes manual changes, colour consistency will suffer. The goal is not just a good first print, but a process that gives the same result on Monday morning and again on Friday afternoon. That matters for sign shops handling repeat orders, vehicle graphics and municipal work where matching is expected.
We help you tighten the workflow so each job follows the same route through setup, RIP and print. For many South African shops, this also means working around load-shedding interruptions and restarts without losing the production settings.
- Create named presets for each common media type.
- Lock the settings that should not change between operators.
- Keep a simple job note for profiles, ink limits and pass settings.
- Back up presets after every major change or upgrade.
Use test prints to isolate the fault
A proper test print saves time and material. Rather than reprinting a full board or a long roll, print a controlled strip or a small colour chart and compare it to the approved target. If the problem is in magenta, for example, the test should show whether the shift is coming from the file, the ink channel or the media response.
For coastal sites in Durban or Gqeberha, humidity can change drying behaviour and surface finish. In Gauteng, dust and static can affect some media. A short test run helps separate environmental issues from software settings, and it keeps the workshop from wasting expensive stock.
- Print a small control strip before the full job.
- Compare solids, skin tones, greys and brand colours.
- Note whether the issue appears on all media or only one type.
- Check if the fault gets worse after pauses or power interruptions.
When colour still shifts, review the RIP queue and printer settings
If the file and profile look correct, the next step is to review the RIP queue and printer configuration. Jobs can inherit old settings, queue items can be processed in the wrong order, and a changed profile can slip in without anyone noticing. That is where support from a trained technician helps.
We look at queue order, nested settings, ink limits, resolution, scaling and any overrides made at the machine. Sometimes the fix is small, like resetting one preset, and sometimes it means rebuilding the queue structure so the operator can work faster with fewer mistakes.
Our support team can assist remotely for quick checks, or on site for shops that need hands-on setup and training. We support businesses in Randburg, Johannesburg, Pretoria, Midrand, Centurion, Durban, Cape Town and Gqeberha, with practical help for sign-making, cutters and print workflow.
Keep repeat orders consistent over time
Once the colour check is sorted, the important part is keeping it that way. Repeat work should not depend on one person remembering what was changed six months ago. We help set up a simple record for approved media, RIP presets and client expectations so the next run starts from the right point.
This is especially useful for shops doing ongoing work for schools, estates, franchises and local contractors. If the colour standard is clear, the team spends less time guessing and more time producing clean work.
- Keep approved samples with the job notes.
- Record the media, preset and operator used for the final approved print.
- Review colour setup after software upgrades or printer servicing.
- Book refresher training for new staff before they handle repeat orders.
