成像材料.插图彩色映像打印.室外条件下图像稳定性评估法

[中文适用范围]： 本国际标准描述了用于确定摄影彩色图像在室外条件下的颜色稳定性的测试设备和测试程序。 它没有指定可接受的限制或失败标准。 相反，它提供了测量绘画摄影图像老化过程中发生的图像变化的方法，并指示应报告的关键图像变化参数。 本国际标准的用户应确定哪些测试端点最能模拟预期的显示应用。 本国际标准适用于用数字印刷介质制作的图案图像，例如： ——在涂层纸、涂层和未涂层透明和不透明薄膜、乙烯基、聚酯、合成纸和其他塑料基材上打印，层压和非层压； ——使用水性、溶剂性、相变或 UV 固化墨水的染料基和颜料基喷墨打印； ——热染料和传质； ——热升华印花； ——数码印刷的染料扩散转印印刷品； ——液体和干墨粉静电印刷； ——液体墨粉静电打印； ——用传统显色和银漂白感光材料制成的数字印刷图像； ——彩色直接热敏打印。 在这些数字印刷过程中，油墨沉积是通过数字像素信息来控制的，并且印刷系统的所有设置和控制都可以记录和重复。 相比之下，对于许多模拟印刷系统来说，对墨膜厚度的控制可以通过手动调节来实现。 本国际标准涵盖窗户外侧的窗户图形。 ISO 18937 将涵盖窗户内侧的窗户图形，其中阳光被一层玻璃过滤。 该国际标准不包括图像、支撑物或粘合剂材料的物理稳定性的测试程序。 然而，人们认识到，在某些情况下，决定印刷材料使用寿命的是物理降解，例如载体脆化、图像层破裂或图像层与其载体的分层，而不是图像稳定性。 注意 针对一种打印机型号、墨水组、打印模式、打印分辨率和介质组合确定的图像打印稳定性结果不适用于通过另一打印机型号、墨水组、打印模式、打印分辨率和介质组合生成的图像打印件，即使墨水测试中使用的喷射墨盒和/或介质是相同的。 [外文原描述]： This International Standard describes test equipment and test procedures for determining the colour stability of photographic colour images when subjected to outdoor conditions. It does not specify limits of acceptability or failure criteria. Instead, it provides means for measuring image changes that take place during the aging of pictorial photographic images and indicates the critical image-change parameters that should be reported. Users of this International Standard should determine which test end-points best simulate the intended display application. This International Standard is applicable to pictorial images made with digital printing media, for example: — prints on coated papers, coated and uncoated clear and opaque films, vinyl, polyester, synthetic papers and other plastic substrates, laminated and not laminated; — dye-based and pigment-based inkjet prints with aqueous, solvent, phase-change, or UV curing inks; — thermal dye and mass transfer; — dye sublimation prints; — digitally-printed dye-diffusion-transfer prints; — liquid- and dry-toner xerographic prints; — liquid toner electrostatic prints; — digitally printed images made with traditional chromogenic and silver dye-bleach photographic materials; — colour direct thermal prints. In these digital printing processes, the ink laydown is controlled by means of digital pixel information, and all of the settings and controls of the printing system can be documented and repeated. In contrast, for many analogue printing systems, the control over the ink film thickness can be subject to manual adjustment. Window graphics on the outside of windows are covered by this International Standard. Window graphics on the inside of windows, for which sunlight is filtered by a layer of glass, will be covered by ISO 18937. This International Standard does not include test procedures for physical stability of images, supports or binder materials. However, it is recognized that in some instances physical degradation such as support embrittlement, image layer cracking, or delamination of an image layer from its support, rather than image stability, will determine the useful life of a print material. NOTE Image print stability results determined for one printer model, ink set, printing mode, print resolution and media combination are not applicable to image prints produced through another printer model, ink set, printing mode, print resolution and media combination, even if the ink jet cartridges and/or media used in testing are the same.
