Designation:F117588(Reapproved 2011)Standard Practice forUsing the Computer Impact Print-Out Unit as a TestInstrument for Manifold Comparison1This standard is issued under the fixed designation F1175;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,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 covers a standardized procedure utilizingthe computer impact print-out unit as an imaging device wherethe performance properties of carbonless paper,carbon paper,and similar image-producing products are measured.Theprinter can be either a high speed printer connected to amainframe computer or a printer connected to a personal ormini-computer.1.2 The values stated in inch-pound units are to be regardedas the standard.The SI values in parentheses are given forinformation only.1.3 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 prior to use.2.Referenced Documents2.1 ASTM Standards:2D585 Practice for Sampling and Accepting a Single Lot ofPaper,Paperboard,Fiberboard,and Related Product(Withdrawn 2010)3D685 Practice for Conditioning Paper and Paper Productsfor TestingF221 Terminology Relating to Carbon Paper and InkedRibbon Products and Images Made TherefromF549 Terminology Relating to Carbonless Copy ProductsF909 Terminology Relating to Printers3.Terminology3.1 Definitions:3.1.1 For definitions of terms used in this practice,refer toTerminology F221,F549,and F909.3.2 Definitions of Terms Specific to This Standard:3.2.1 continuous envelopesproduct for tests,producedwith control punched margins so that they can be used onequipment with pinfeed platens.A horizontal perforation(be-tween set perf)allows the forms to be folded,and 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 comparative 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 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 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.NOTE1Some printers(for example,the IBM Model 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 dayscould show variations in results.All tests should be dated andtemperature and relative humidity data recorded.Control setsshould be included in all runs.1This 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 Oct.1,2011.Published March 2012.Originallyapproved in 1988.Last previous edition approved in 2006 as F117588(2006).DOI:10.1520/F1175-88R11.2For referenced ASTM standards,visit the ASTM website,www.astm.org,orcontact ASTM Customer Service at serviceastm.org.For Annual Book of ASTMStandards volume information,refer to the standards Document Summary page onthe ASTM website.3The last approved version of this historical standard is referenced onwww.astm.org.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 6.4 Carbonless copy products image intensity developmentmay vary with time depending on manufacture.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 caliper 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 a
