What is ISO 18949 - Reflection colour photographic prints about ?
ISO 18949 discusses evaluating the reflection colour photographic prints.
ISO 18949 describes test methods to evaluate reflection colour photographic prints with regard to changes in image appearance resulting from exposure to low relative humidity.
The observed changes relate primarily to substrate yellowing. Other observed humidity related physical damage factors such as curl, cockle, cracking, or delamination due to humidity cycling are also within the scope of this test method.
Who is ISO 18949 - Reflection colour photographic prints for ?
ISO 18949 - method for testing stability under low humidity conditions is useful for:
- Photographic prints testers
- Printing production personnel
- Printing professionals, including auditors, consultants, etc
Why should you use ISO 18949 - Reflection colour photographic prints ?
ISO 18949 covers the methods and procedures for testing the low humidity fastness of reflection colour photographic prints. Both low and high relative humidity testing is of particular relevance to dye- and pigment-based inkjet prints printed on swellable and porous media, dye diffusion process prints, and silver halide prints. The method and procedures described in ISO 18949 can be used to test any colour hardcopy technology. ISO 18949 also helps you in visual assessment and reporting of physical degradation in reflection colour photographic prints due to low humidity conditions.
In conclusion, the test method described in ISO 18949 helps you to verify the stability of reflection colour photographic prints under low humid conditions. This enables you to identify the ink and print quality of your photographic prints.
