7、test pattern that may be usedto determine how many characters a ribbon will producethroughout its life.Testing involves using the intended type-writer or printer and printing through the end of the ribbon.4.3 With this information the ribbon user can calculatecharacter yield information for competit
8、ive comparisons,dif-ferent cartridge designs,differences between various ribbonink formulations,and cost per character.4.4 Character counts are divided into two different testpatterns:one for correcting typewriters;one for printers andnoncorrecting typewriters.5.Significance and Use5.1 The character
9、 yield of a ribbon is affected by manyfactors including the printer/typewriter design and ribboncartridge design.The end user may wish to evaluate thesedifferent machine and ribbon designs to determine the esti-mated cost of various systems over the anticipated useful life ofthe equipment.For exampl
10、e,the lowest cost machine may notbe the most economical system when the cost per character(cost of supplies)is factored in as part of its total life time cost.6.Interferences6.1 The test paper used in testing may impact the generalimage quality.6.2 The actual character yield may also be impacted byr
11、ibbon length,ribbon advance rate,and character pitch.Theribbon advance rate is controlled by such things as the cartridgeribbon metering design,printer/typewriter design,film basestability,and ribbon slippage.7.Apparatus7.1 Typewriter or Printer,set to manufacturers specifica-tions including enough
12、memory,or a robotics device capable ofrunning the test pattern in a repeating sequence until the ribbonis exhausted.8.Test Pattern8.1 For correction typewriters,the test pattern has 1951operations,of these 1299 are printing and 652 are nonprinting.For printers and machines without correcting,there a
