Arti dan kegunaannya
5.1 The light resistance of printing inkjet media over a specified period of time is related to the end use of these materials. Since the ability of inkjet prints to withstand color changes is a function of the spectral power distribution of the light source to which they are exposed, it is important to evaluate light resistance under conditions suitable for the end use. While inkjet printing can be processed and displayed under a variety of conditions, this practice is designed to mimic those conditions to produce the color changes that inkjet printing may experience when exposed to sunlight filtered through window glass.

5.2 The accelerated procedures covered in this procedure are intended to provide a method for rapid assessment of relative light resistance under laboratory test conditions. The practice does not provide a rating of the light resistance of prints, but determines the light resistance rating of a range of prints or their performance compared to controls with known light resistance. The test results are useful for specification acceptance, kontrol kualitas, and research and product development between producers and users.

5.3 Color change may not be a linear function of exposure duration. The method of choice to determine the light effect is to expose the print at multiple intervals and evaluate the exposure time required to obtain a specific color change or change in light density.

1.1 This procedure covers specific procedures and test conditions applicable to xenon arc exposure for prints of inkjet media carried out in accordance with practices G151 and G155. The Lab accelerator program is designed to determine the relative light resistance of inkjet printing in office environments that use Windows to filter daylight for lighting.

1.2 Two criteria used to determine relative light resistance are instrument color change and light density change.

1.3 This practice helps to determine the relationship between the relative light resistance of a range of prints or the light resistance of prints of interest and the performance of known light resistance controllers that are simultaneously exposed.

1.4 Standar ini tidak dimaksudkan untuk mengatasi semua masalah keselamatan, jika ada, terkait dengan penggunaannya. Pengguna standar ini bertanggung jawab untuk menetapkan praktik keselamatan dan kesehatan yang sesuai dan menentukan penerapan pembatasan peraturan sebelum digunakan.. Section 8 gives specific precautions.

1.5 There is no equivalent ISO standard.
