Analysis of DIN ISO 12040 Printing ink xenon arc aging test colour fastness method

DIN ISO 12040 is a standard published by the German Institute for Standardization (DIN) that provides guidelines for the evaluation of the lightfastness of printed matter and printing inks using filtered xenon lamps. The standard is designed to help printers, ink manufacturers and other professionals in the graphics technology industry evaluate the resistance of prints and inks to the effects of light exposure.

This standard specifies procedures for exposure testing using xenon lamps with specific filters to simulate the effects of natural sunlight. The standard includes guidelines for selecting appropriate test conditions, including the intensity and spectral distribution of light sources, and guidelines for preparing and handling test samples, including their size and shape and the conditions under which they are tested.

DIN ISO 12040 provides several performance criteria for evaluating the lightfastness of prints and inks exposed to xenon arc light, including color change, fading and loss of gloss. The standard also provides guidance for the calculation and reporting of test results, including the use of statistical methods to analyze and compare data.

In addition, DIN ISO 12040 provides recommendations for the design and construction of xenon arc exposure equipment to ensure consistent and reliable results. The standard covers aspects such as lamp selection, optical filters and temperature control.

The use of DIN ISO 12040 is not limited to the graphic technology industry. Other sectors such as the textile, packaging and automotive industries also use the standard to assess the light fastness of their products.

By following DIN ISO 12040, manufacturers can ensure that their prints and inks meet the necessary requirements for lightfastness, which is very important for applications where the durability of printed materials is important. This includes outdoor advertising, packaging and textiles, among others.

All in all, DIN ISO 12040 is an important standard that provides guidance for the evaluation of the lightfastness of printed matter and printing inks using filtered xenon lamps, which is very important for ensuring the quality and durability of printed materials. By following the guidelines set forth in this standard, printer and ink manufacturers can thereby ensure that their products meet the necessary performance standards for resistance to light exposure, improving the quality and longevity of their products.
