1、Designation: F2035 00 (Reapproved 2011)Standard Practice forMeasuring the Dark Stability of Ink Jet Prints1This standard is issued under the fixed designation F2035; the number immediately following the designation indicates the year oforiginal adoption or, in the case of revision, the year of last
2、revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon () indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice describes an accelerated procedure in-tended to determine the dark stability of ink jet prints.1.2 This stand
3、ard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2.

Summary of Practice4.1 Printed test samples are covered with a polyethyleneterephthalate (PET) sleeve4to simulate an album, or with asample of the same sample type to simulate a stack of prints,and placed in foil-lined bags. Air is forced out of the bags
7、 andthe bags are sealed. The bags are placed in dark recirculatingforced-air environmental chambers at 50C/50 % RH and24C/50 % RH and the color change of the samples is thenmeasured over time.NOTE 1The foil bags serve several purposes: they protect thesamples, they prevent any outgassing from the sa
8、mples from contaminat-ing other samples in the test chamber, and they ensure contact of the PETor receiver to the samples.4.2 The duration of the incubation may vary widely depend-ing on the dark stability of the ink/media.4.3 During the course of the test, the color changes in theprinted samples ar

The color changeis reported as percent retained optical density and colordifference, DE.4.4 The test may be continued for a specific duration of timeo
10、r until a predetermined color difference has been achieved.5. Significance and Use5.1 Dark stability of printed ink jet media for specifiedperiods of time is pertinent to the end use of these materials.While natural aging is the most reliable method of assessingimage stability, the length of time re
11、quired makes this practiceimpractical for most materials. As a result, accelerated testsoften are used. This practice is an accelerated short-termstorage practice that simulates long-term storage but at el-evated temperature. It provides faster results and is intended toidentify problems that may oc
12、cur over extended time periods.A room condition sample also is tracked to provide practicaldata. Because testing is done at a single set of conditions, it isnot intended to be a long-term predictor as achieved throughArrhenius testing.NOTE 2The results from single accelerated tests can lead to inacc
13、u-rate results. This procedure should be used only for early-screeninginformation in side-by-side comparisons only. Arrhenius testing, which isbased on mathematical extrapolation of a series of high temperature teststo room temperature, is a better predictor of a products stability.55.1.1 Since the
