1、Designation:F249805(Reapproved 2011)Standard Practice forDetermining the Drying Time of Inkjet Media and Inks Usinga Smudge Method1This standard is issued under the fixed designation F2498;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revis

2、ion,the year of last 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 a procedure for assessing thedrying time of black and white or color images produce

3、d byinkjet printers by smudging yellow,magenta cyan,red,green,blue,and black printed color bars.1.2 This practice can be used to test different media with agiven set of inks or it can be used to evaluate different inks witha given media.1.3 This method is applicable to printed images,where theimage

4、may be contacted after printing.1.4 This standard 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

5、 prior to use.2.Terminology2.1 Definitions:2.1.1 ink jet mediarefer to recording elements used by inkjet printers to receive inks.The substrate may be paper,plastic,canvas,fabric,or other ink receptive material.The substratemay,or may not,be coated with an ink receptive layer(s).3.Significance and U

6、se3.1 In addition to providing acceptable image quality,ink jetmedia have to dry in a reasonable time period so that the imageis not perturbed by handling after imaging.3.2 Good drying time is a prime consideration for inkjetinks and media.An inkjet print which does not dry in areasonable time perio

7、d has limited usefulness.This practice isused to obtain comparative data of drying times for inkjet inksand media.4.Interferences4.1 Since the drying time of inkjet inks and media isdependent on temperature and humidity,it is important that themeasurements be made under the conditions appropriate to

8、 theend use applications.While printed media may be handled anddisplayed under a variety of conditions,this test practice isintended to determine drying time in indoor environments.4.2 The drying time is dependent on temperature andhumidity,and should be measured within the temperatures andhumiditie

9、s specified by the printer or media manufacturer.4.3 The drying time is dependent on the printing mode,thetype of color and the amount of applied inks.4.4 This procedure is only applicable for determining drytime,when the drying time exceeds the actual print time.5.Materials5.1 Printer,media,stopwat

11、phics,or page layoutsoftware,saved as a print file for each printer/method ofprinting(contributing its unique inks and inks/receiver inter-actions that may impact drying time),trial-printed,and evalu-ated for appropriate ink letdown(purity and amount)and easeof printing and testing.Each print file s

12、hould have its filename,type,and version identified in the image area and a place forexperimental notes(for example,time,printer,environmentalconditions,operator).The printer settings and a trial print ofeach print file version should be archived.6.3 The test image should be constructed such that th
