Designation:D695908Standard Practice forData Exchange Format for Sewn Product Plotting Devices1This standard is issued under the fixed designation D6959;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 describes a data format for transferringinformation from a sewn product computer aided designsoftware program to a device that produces physical output,typically in the form of a printed or drawn image on paper.1.2 This practice is based on a subset of the Hewlett PackardGraphics Language HPGL/2.Supported syntax and limitationsare listed in 7.2.Unsupported syntax is listed in X1.1.1.3 This practice only supports X-Y vector data and a limitedset of additional functions.No provision is made to supportbitmap/raster data used in applications like inkjet printing.1.4 This practice supports a single system of units,an imagefixed at 100%scale and 1:1 aspect ratio.Scaling and customunit systems are not supported.1.5 This practice does not support curve interpolation ordefinitions.All curves are represented by discrete vectors(stroked)and are dependent on the resolution of the CADsoftware.1.6 This practice requires that all coordinates are absolute,not relative,as defined in the HPGL/2 reference.1.7 This practice only supports positive coordinates that aremeasured from a single X-Y origin point with coordinates 0,0.1.8 This practice only supports fixed width fonts.Variablewidth fonts are not supported.1.9 This practice intends to transfer a static image with noprovision for editing.1.10 This practice assumes monochromatic output.It doesnot support implied output colors.1.11 This practice imposes no limits on the width or lengthof the plot data.Physical limitations imposed by the hardwareand their effects on the output are the responsibility of thehardware manufacturer.1.12 This practice does not support frame advance com-mands or any methods that insert multiple origin points orfloating coordinate systems.1.13 This practice limits the plot file to contain a singleblock of data demarked by a compatible header and terminator.Multiple blocks of data in a single file are not allowed.1.14 The intended application of this practice is limited tothe class of output devices found in the sewn product industriesthat produce apparel,textiles,upholstery,and others that usesoft or semi-rigid materials.1.15 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:2D6963 Terminology Relating to Sewn Products Automation3.Terminology3.1 Definitions:For definitions used in this practice,seeTerminology D6963.4.Summary of Practice4.1 Plot data are organized to allow a parsing algorithm torecognize adherence to the ASTM format then are written as adata block into a computer file.4.1.1 A specific group of commands are required at thebeginning of the data block,called a header.4.2 Plot data follow a subset of the HPGL/2 ASCII lan-guage.4.2.1 The practice specifies syntactical and parametric con-straints to limit ambiguity.4.2.2 Basic HPGL formatting is supported.AdvancedHPGL functions are beyond the scope of the practice.5.Significance and Use5.1 This practice provides a common format that allows acomputer design system to generate data that an output devicecan accurately reproduce independent of the hardware manu-facturer.1This practice is under the jurisdiction ofASTM Committee D13 on Textiles andis the direct responsibility of Subcommittee D13.66 on Sewn Product Automation.Current edition approved July 1,2008.Published August 2008.Originallyapproved in 2003.Last previous edition approved in 2003 as D6959 03.DOI:10.1520/D6959-08.2For 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.Copyright ASTM International,100 Barr Harbor Drive,PO Box C700,West Conshohocken,PA 19428-2959.United States1 6.Plot File6.1 Plot data are written in data blocks of ASCII characters,one data block per computer file.6.2 Data blocks are made up of commands.6.2.1 Each command is a two-letter sequence(see 7)alwayswritten in CAPITAL letters.6.2.2 An instruction and its associated ed parameters(ifrequired)are terminated by the semi-colon(;)terminator.Otherterminators are not supported that is mnemonic,or.6.3 Some commands are followed by parameters.6.3.1 Parameters immediately follow the command with noseparating space and come before the command terminator.6.3.2 Multipl
