(Practice)Standard Practice for Electronic Interchange of Color and Appearance Data
Standard Practice for Electronic Interchange of Color and Appearance Data
SIGNIFICANCE AND USE
5.1 This practice should be used by manufacturers of color-measuring instruments and developers of software when the transmission of color and appearance data is desired between instruments or computers and where ASCII files are the desired method of transfer.
5.2 The method of transmission may be via direct connection, modem, or the transfer of electronic media, for example, by floppy disk transfer.
5.3 The practice lends itself to the transmission of either a single record of data or multiple record files.
5.4 Examples of files generated in this practice are contained in Fig. X1.1 and Fig. X2.1 of Appendix X1 and Appendix X2.
SCOPE
1.1 This practice covers procedures to be used in the electronic exchange of color and appearance data between users, by either modem or the physical transfer of electronic media. It is intended for use by manufacturers of color-measuring instruments and developers of software so that any instrument may acquire data for its use that may have been measured on an instrument of another manufacturer, at another place, or at another time.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.3 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

the transmission.
5. Significance and Use
5.1 This practice should be used by manufacturers of color-measuring instruments and developers of software when the
transmission of color and appearance data is desired between instruments or computers and where ASCII files are the desired
method of transfer.
5.2 The method of transmission may be via direct connection, modem, or the transfer of electronic media, for example, by
floppy disk transfer.
