ASTM F1942-1998(2003) Standard Practice for Creating Test Targets for Determining the Ink Yield of the Imaging Supplies Used in Ink Jet Printers《创建测定喷墨打印机用成像供给的油墨成品的试验目标的标准操作规程》.pdf

1、Designation: F 1942 98 (Reapproved 2003)Standard Practice forCreating Test Targets for Determining the Ink Yield of theImaging Supplies Used in Ink Jet Printers1This standard is issued under the fixed designation F 1942; the number immediately following the designation indicates the year oforiginal

2、adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. Asuperscript epsilon (e) indicates an editorial change since the last revision or reapproval.1. Scope1.1 This practice describes a method for creating test targetscontainin

3、g varying percentages of area coverage for use indetermining the yield of the supplies used by liquid and solidink jet printers.1.2 This standard may involve hazardous materials, opera-tions and equipment. This standard does not purport to addressall of the safety concerns, if any, associated with i

4、ts use. It isthe responsibility of the user of this standard to establishappropriate safety and health practices and determine limita-tions prior to use.2.

Summary of Practice4.1 The test targets which are created using this practice areused

6、 to determine the page or ink yield (in in.2/g of ink) of inkjet printer supplies.4.2 The test targets may be generated by a printer, verifiedfor percentage of area coverage, and used to determine thepage yield of ink jet printer supplies.4.3 With this information, the user can determine supply-yiel

7、d information for purposes of competitive comparisons orthe determination of cost-per-page.4.4 The test targets which are created using this practice canbe used to calibrate the equipment used to verify percent areacoverage.5. Significance and Use5.1 Test targets where the percentage of area coverag

8、e hasbeen predetermined are not readily available from commercialsources. Moreover, it is beyond the ability of most users toverify if indeed, the commercially-available test targets containthe advertised area coverage. This procedure allows the user toeasily create test targets, using commercially

9、available PCsoftware, which can be easily verified for percentage of areacoverage and can provide reproducible interlaboratory results.6. Interferences6.1 Consider the resolution of the ink jet printer for whichthe test target is being created. In other words, size theelements so that they can be di

10、vided evenly by the resolutionof the printer. This will ensure that the printer will only outputentire pixels, and will not be forced to use resolution enhance-ment techniques, such as modulation of the pixel size.6.2 When creating the elements in the test target, considerthe aperture size of the de

11、nsitometer which will be used tomeasure the output density. The elements created shouldcomfortably fit within the densitometer aperture area.7. Apparatus7.1 Personal computer and ink jet printer.7.2 Personal-computer word processing or page layout(desktop publishing) software, which allows the user

12、to specifythe size, create, copy and place graphic elements on a page.8. Creating the Test Target8.1 Determine the intended test target percent area cover-age. For example, the current industry-accepted area coverageis 5 % area coverage for black- and -white images and 15 % forfull-color images.1Thi

13、s practice is under the jurisdiction of ASTM Committee F05 on BusinessCopy Products and is the direct responsibility of Subcommittee F05.07 on Ink JetImaging Products.Current edition approved Dec. 10, 1998.

15、he number and dimensions of elementsrequired for the application. Although only one element isrequired, it may be desirable to arrange several smallerelements around the page to produce areas suitable for densi-tometer measurement within the test target (refer to Fig. 1).8.3 Create a new document wi

16、th a word processor ordesktop publishing software program.8.4 Access the drawing tools and create an element with theproper dimensions.8.4.1 Some programs provide a dialog box which allows theuser to enter the dimension from the keyboard.8.5 Using the software, specify the color of the element(cyan,

17、 yellow, magenta or black).8.6 If necessary, use the software to copy the element therequired number of times and arrange the elements on the page.8.6.1 Do not place elements within the unprintable area ofthe intended printer. This area is usually from 0.3 in. to 0.55 in.around the perimeter of the

18、page depending on the printer;consult the printer manual for details.9.
