Printhead energy is a function of both pulse width(strobe time or Ton) expressed in milliseconds (ms) and energyexpressed in
10、 millijoules (mJ). When energy is expressed inmillijoules, printhead resistance is taken into account. Thermalresponse plots are commonly prepared both ways. The latter ispreferred.3.2 Symbols:3.2.1 Tcyclethe time between printed lines. The larger theTcyclevalue, the more time between printed lines.
11、 The result isslower print speeds. Smaller Tcyclevalues correspond to fasterprint speeds. Time between printed lines equals dot “on” timeplus dot “off” time (Tcycle=Ton+Toff).3.2.2 Tonthe amount of time that the heating elements(dots) on the printhead are energized. Typically, this value is inmillis

The equipment is the same as that covered in TestMethod F 1405. The equipment differs from that used in TestMetho
13、d F 1405 in that it contains apparatus to allow forthermal ribbon supply and take-up rolls (see Fig. 1). Thesystem is designed to provide thermal response measurementsusing printheads commonly used in facsimile units, labelprinters, medical recorders, plotters, and other thermal printers.This system
14、 is based on a special purpose controller board,which drives a standard thermal printer using a programmablestepping drive controller. This system includes provisions formounting standard performance printheads. A personal com-puter controls the system with parameter programming accom-plished from m

17、 determine thermal response, thermal product in rollor sheet form is fed into the printer. From the main menu, thetest system is configured to the test mode. Again from the mainmenu, “execute a test” is chosen. A standard existing test filecan then be loaded and the new test can be given a file name
18、or default standard test conditions can be used. The test thermalproduct (media) is identified, printhead voltage set, and the testexecuted. Densitometer measurements can then be entered intothe test file (manually or automatically). Data in the test filecreated can then be used to graphically displ

Thus, this system is useful in matching thermal transferproduct performance to various thermal printhea

21、 match withcertain printhead designs.5.3 Manufacturing process control can make thermal re-sponse comparisons relative to process changes.5.4 Customers for thermal products can use this test methodto compare supplies from various manufacturers.5.5 The test system can be used to evaluate thermal re-s
