IPM – Light audit (ISO 3664:2009)
The light has a considerable influence on the quality of visual sampling and colour communication. The right lighting is therefore an essential and not to be underestimated success criterion.
So that complaints do not arise in the first place, the customer only has to be satisfied with the print result. This sounds quite simple, but is always associated with difficulties in everyday life. Despite a largely industrial and standardized production and the fact that the finished print products (metrologically correct) correspond to the proof, print service providers are always faced with the problem that print products look completely different in the eyes of the customer than they imagined when they were created. It is always a question of (color) correct lighting how your customers perceive print products.
1. Inventory of the sampling places in accordance with ISO 3664:2009:
Metrological evaluation of the lighting situation in sample areas. This includes the standard light as well as the ambient light, since even an extraneous light component of 10% to 20% is sufficient to noticeably impair the colour rendering properties of a printed product.
2. Consulting in dealing with optically brightened media
(OBA and UV shares):
OBA (Optical Brightening Agents) is the abbreviation for optical brighteners.
Function: The human eye can only perceive a tiny part of the electromagnetic radiation of light, which is expressed in wavelengths (nanometers). This part is called the visible spectrum and lies between 380 nm (ultraviolet limit) and 780 nm (ultrared limit).
The natural cellulose fibres (omnipresent in paper production) tend to absorb rays in the blue range and thus appear yellowish. An optical brightener “compensates” this loss in the spectrum artificially (the colors blue and yellow cancel each other out as complementary colors). The paper thus appears whiter and brighter thanks to fluorescent effect whiteners.
Disadvantages: Optical brighteners lose their properties over time, which results in a “white loss” of the paper. Influencing factors that should be known.
3. Lighting analysis of the general lighting in accordance with the Workplace Ordinance (ASR A3.4 and DIN EN 12464-1):
Metrological analysis of light in offices, conference rooms and printing rooms, in which proofs or print products are examined and evaluated together with the customer independently of the sample.
4. Investment consulting
Every one of us has a duty to act sustainably, to meet the requirements of climate protection and to meet budget targets. If you are thinking of investing in a new lighting system, we will ensure that this investment does not become a gamble. This is because understanding the total operating costs of a lighting system over its entire service life is becoming increasingly important.
The IPM light audit puts you in a position to systematically check the lighting situation and initiate measures to reduce the associated energy consumption sustainably and in the long term.
As a rule, efficiency measures for the lighting system have a payback period of no more than three to five years. In addition, optimised lighting systems improve the productivity of your employees and thus reduce attention and concentration disturbances caused by unfavourable lighting conditions.
Based on the analysis results and their relevance for the assessment of print products, concrete suggestions are made as to which lighting solutions can be used to create cost-saving and energy-efficient better lighting conditions for the critical inspection of print products.
The evaluation of the lighting conditions in the sampling process as well as in conference rooms and offices is primarily based on the size of the company. As a rule, in a medium-sized company about three to four hours are required for the pure (photometric or metrological) analysis on site.
5. Expert opinion with professional light evaluation and proposals for a conversion concept:
Of course, you will receive a comprehensive report after completion of the evaluations, in which you will be informed about possible alternatives, their costs and benefits as well as recommendations.

In a nutshell:
The influences of room lighting on standard lighting equipment, softproof monitors and the perception of the observer are often underestimated.
The IPM light audit serves to record all influences of the existing lighting situation as a basis for assessment and optimisation. Existing standard lighting equipment, the entire room lighting, room dimensions, positioning of workplaces and factors such as glare, reflection, incidence of ambient light and the overall quality of scattered light are measured, systematically recorded and analysed.
The IPM light audit provides you with the necessary recommendations to sustainably optimise the lighting situation in your company:
