Repainting a single panel is harder than painting a whole vehicle. A whole vehicle is compared against itself; a single panel is compared against its neighbour under whatever light later falls on it.
Colour matching after modification is therefore settled inside the chamber before it is settled at the mixing bench: higher lighting is a published configuration item for this work specifically.
Why lighting comes before material
The technician judges the difference by eye while spraying. If the light inside the chamber is weaker than the light that will fall on the vehicle outside it, a difference invisible in the booth appears in the first daylight — after the work has been finished and handed over.
Where the item sits in the configuration
| Item | What changes | Why |
|---|---|---|
| Lighting | Higher lighting inside the chamber | Colour-matching work |
| Air volume | Higher than the mid range | Throughput counted in vehicles per day |
| Heat cycle | Faster | Daily throughput |
| Footprint | Standard automotive footprint | Passenger cars and SUVs |
And education asks for the same item for another reason
In education and training, higher lighting is called for as well, together with observation windows, a control panel showing cycle stages to trainees, and short repeated cycles. The same configuration item therefore serves two different purposes: visibility for the work, and visibility for the learning.
Frequently asked questions
How is the lighting level fixed?
What is published is a configuration item: higher lighting inside the chamber for colour-matching work. The level is fixed with the configuration against size and type of work, and signed off before manufacture along with the rest of the configuration rather than after installation.
Is standard ceiling filtration enough for this work?
Ceiling filtration is specified at the highest class the model offers for vehicle handover work, and the classes delivered in this family are EU3, EU4 and EU5. The class is set with the configuration rather than after installation.
Does the chamber differ from a full-respray booth?
The size is the same — the standard automotive footprint. What changes is air volume, heat cycle and lighting, all configuration items inside the same chamber.
Does the heating system affect colour matching?
What affects it is the heat curve rather than the system itself. Five systems are delivered in this family, and the choice among them follows the coating type and the cost of energy on site.
