A horizontal perforation (be-tween set perf) allows the forms to be folded, and

8、 subsequentlyseparated into individual envelopes (see Fig. 1 and Fig. 2).4. Summary of Practice4.1 This practice consists of using a computer print-out unitunder specified conditions to prepare images which are used toevaluate carbon paper, carbonless paper and other types ofmanifold sets on a compa

9、rative basis.5. Significance and Use5.1 This practice is intended to provide a means of evalu-ating comparative image quality relative to carbonless paper,carbon paper, and similar image-producing products.6. Interferences6.1 Some printers vary in their impact pressure and printingspeed. Comparison

10、tests must be run on the same printer andprogram or portion of program for each part of the test. Somesmaller printers will not be able to image multiple set forms.6.2 Caliper variations between test manifold sets can affectimage intensity and sharpness. If possible, measure caliper ofmanifold sets

11、and set printer adjustments accordingly. Differentcaliper settings should be used when running a four-part asopposed to a six-part set. All similar multiple part sets shouldbe gaged and printed in the same run. Record caliper andprinter adjustment data.NOTE 1Some printers (for example, the IBM Model

12、 3211) automati-cally establish the printing pressure by means of a “forms thicknesssensor button. See 13.1.1 to ensure that the test manifold set is properlypositioned for evaluation.6.3 Fluctuations of temperature and humidity will affect thepaper used for image reception. Tests run on different d

13、ayscould show variations in results. All tests should be dated and1This practice is under the jurisdiction of ASTM Committee F05 on BusinessImaging Products and is the direct responsibility of Subcommittee F05.06 onCarbonless and Thermal Imaging Products.Current edition approved June 1, 2006.

Comparisontests, therefore, must include a control from the same manu-facturer printed in the same run.6.5 Image performance is a function of the number of plies,basis weight and type of paper used in the manifold sets. Formsets with differences in ca

17、liper would be expected to yielddifferences in image performance.7. Apparatus7.1 Printer, to be used to prepare images; a computer impactprinter in normal use and adjusted to the manufacturersspecifications.8. Materials8.1 Use 15# (17 in. by 22 in.

Sampling9.1 Sample the carbonless paper, carbon paper, or othermaterials to be tested in accordance with Practice D 585.FIG. 1 Manifold Set PositionFIG. 2 Envelopes for Imaging TestsF 1175 88 (2006)210

20、. Preparation of Apparatus10.1 Using manifold set caliper data, adjust the printer to theproper caliper setting and record this setting.11. Standardization11.1 Establish a print-out test program utilizing both char-acters and numerals. It is preferable to print at six lines/in. anddouble space. This

21、 test program is to be printed on all manifoldsets to establish a comparison standard.12. Conditioning12.1 Testing shall be conducted in an environment withstable conditions of temperature and relative humidity. It issuggested that test material (manifold sets) be conditioned for24 h in the area in

22、which testing will be conducted. If available,standard conditions of 50.0 6 2.0 % relative humidity and 23.06 1.0C should be used (see Practice D 685). If other condi-tions are used, record the temperature and percent relativehumidity.13. Procedure for Preparing Image13.1 Assemble the test and contr

23、ol manifold sets. Onceassembled, check the sets by making a small mark on one edgeto verify that each sheet has been properly inserted. For carbonsets check that each carbon is facing the correct way and thatthe proper number of carbons have been used. For carbonlesssets check that a “coated back” (

24、CB) is in the first position anda “coated front” (CF) is in the last with the internal sheets allbeing “coated front and back” (CFB). Check that each sheethas been inserted with CF facing up and CB down. Prepare thetest manifold samples by one of the following two methods.For both methods, arrange t

25、he manifold sets such that themachine direction of the grain feeds in the direction of travelthrough the computer impact printer. All dimensions stated areapproximate and should be used as a guide.NOTE 2The carrier sheet tape-on method would be expected to givepoorer imaging results since the forms

26、set has a higher overall caliper. Inthe continuous envelope method a window is cut behind the test set.13.1.1 Carrier Sheet Tape-On MethodThe continuouscomputer stock tab forms bond 15-pound (17 3 22 in. (500sheets) (56.4 g/m2) as the carrier system. Allow at least fivesheets of the computer stock t

27、ab forms bond for lead-in.13.1.1.1 Position the manifold set (normally 812 by 9 in.(216 by 229 mm) grain long) on top of the computer stock tabforms bond with the 812-in. (216-mm) edge 1116 (27 mm) fromstock tap perforations and the 9-in. (229-mm) edge 112 in.(23.1 mm) from the left hand punched end

28、 as the stock tabfeeds through the printer (see Fig. 1).NOTE 3When evaluating forms on printers which automaticallyadjust the unit to the form caliper, the test manifold set must be positionedso its left hand edge is14 to34 in. (6.35 to 19.05 mm) from the tractor pinholes along the left-hand side as

29、 the stock tab forms are fed into theprinter. This allows the test manifold set to activate the forms thicknesssensor button.13.1.1.2 Remove trapped air from within the test manifoldset by positioning a board 8 in. by 712 by34 in. (203 by 191 by19.1 mm) weighing approximately 14.1 oz (400 g) in the

30、centeron top of the form set.13.1.1.3 With the board in place and using12 in. (12.7 mm)wide transparent tape (2.5 mils or 0.064 caliper), tape all fouredges of the test manifold set securely to the continuous stocktab sheet.13.1.2 Continuous Envelope Method:13.1.2.1 See Fig. 2 for detail and dimensi

31、ons of a continu-ous envelope system that can be used for this test.Aperforationis used between the individual envelopes for purpose of foldingand subsequent separation. Perforations are provided for re-moval of windows from the front and back of the envelope.13.1.2.2 Use two empty envelopes for lea

32、ding and twoempty envelopes for finishing the run through the printer.Apply tape to avoid catching and tearing at the horizontalperforations of the perforated window areas of the leading andfinishing envelopes, as it is being run through the printer. Use12 in. (12.7 mm) wide transparent tape, that i

33、s 0.0025 in. (0.064mm) in thickness, cut to approximately 1 in. (25.4 mm) longerthan the width of the window areas. Apply tape to both thefront and back, and to the top and bottom of the window areahorizontal perforations. Locate the strips of tape so that theyextend the window widths by approximate

34、ly12 in. on eachside, and so that the top half of the tape is above and the bottomhalf of the tape is below the horizontal perforations.13.1.2.3 Remove the perforated window flaps from the topply of a sufficient number of consecutive envelopes to accom-modate the number of test and control sets to b

35、e run.13.1.2.4 When working with right-hand opening envelopes,insert the manifold test and control sets with the right hand,using the left hand to guide the sets into the individualenvelopes. Make sure sets are properly inserted.13.1.2.5 With the test and control manifold sets properlyinserted in th

36、e individual envelopes, apply strips of transparenttape to the bottom of the window areas. Use tape that is12 in.(12.7 mm) wide and 0.0025 in. (0.064 mm) thick. The tapeshould be cut to approximately 1 in. longer than the width ofthe window area. Locate the strips of tape so that they extendthe wind

37、ow widths approximately12 in. on each side, and sothat the top half of the tape is on the copy ply of a stuffed setand the bottom half of the tape is on the top envelope ply.13.1.2.6 Reposition the complete system so that the frontsare now down on a smooth work surface.13.1.2.7 With the test and con

38、trol sets securely in position,remove the perforated back of each envelope.13.1.2.8 Fasten the lower edge of the window areas on thereverse side in the same manner as 13.1.2.5.13.1.2.9 Carefully force any air that could be occludedbetween the plies out of the opened side of each envelope.13.2 For co

39、ntrol purposes, include manifold sets from thesame manufacturer which, from previous experience, havebeen found to have known performance qualities in normaluse.13.3 Refold the test manifold sets and condition accordingto 12.1.13.4 After conditioning, feed the lead-in into the printer andrunning at

40、normal speed, image the manifold sets in accor-dance with 10.1 and 11.1.13.5 Remove the printed test manifold sets from the printertaking precautions not to fold or otherwise cause smudge orF 1175 88 (2006)3pressure damage. Test manifold sets can then be separated fromthe stock tab or envelope using

41、 a paper cutter or other suitablemeans.14. Procedure for Comparative Image QualityEvaluations14.1 Deleave the plies and visually compare the test andcontrol manifold set images. The images on correspondingmanifold copy should be compared for relative values of thefollowing characteristics:14.1.1 Ima

42、ge intensity,14.1.2 Image sharpness,14.1.3 Image granularity,14.1.4 Image fill-in,14.1.5 Image spread,14.1.6 Cleanliness, and14.1.7 Hammer shadow.NOTE 4When using continuous envelopes, evaluate copy that appearsin the window area only. In addition, do not consider images that areaffected by the addi

43、tional thickness contributed by tape and the envelopesframe itself.15. Report15.1 Report the relative image quality produced from thetest manifold sets as equal to, greater than or less than theimage quality produced from the control manifold sets. Thefollowing features of images can be considered:1

44、5.1.1 Intensity,15.1.2 Sharpness,15.1.3 Granularity,15.1.4 Fill-in,15.1.5 Spread, and15.1.6 Cleanliness.16. Precision and Bias16.1 Repeatable ranking order results or a repeatable rela-tionship to a control can be obtained with this practice providedthat:16.1.1 The same printer in the same condition

45、 is operatedwith similar voltages.16.1.2 Sample conditioning procedures are similar and,16.1.3 Ambient conditions are similar.16.1.4 Equivalent parts from the manifold sets are com-pared.17.
