Summary of Test Method4.1 A printing gage is used to prepare a laboratory printcontaining both the test sample and a standard ink. The freshlyprepared print is immediately subjected to forced hot air in thete
9、ster, which is initially set at 350F (177C) and a belt speedof 30 fpm (0.15 m/s).4.2 The print is cooled, overlaid with a clean sheet of stock,passed through the printing apparatus, and examined for setoff.4.3 The process is repeated at different belt speeds ortemperatures until either the test samp
10、le or the standardexhibits setoff and the other does not, or it is established thatboth are the same. The sample is then reported to dry fasterthan, slower than, or equal to the standard.5. Significance and Use5.1 The setting speed of heatset printing inks is importantbecause it influences the effic
11、iency of the drying process. Thistest method provides a means for comparing the setting of aheatset ink directly against a standard at the same conditions oftemperature and exposure time. While the method does notdetermine the setting speed of an ink on a production press, itis useful for specificat
12、ion acceptance between the supplier andthe customer.5.2 The setting speed of a printing ink depends on a numberof variables such as the substrate on which it is printed, the filmthickness on the print, the temperature of the forced air, the rateof air flow, and the time that the print is subjected t
13、o heat. Forthese reasons, it is important to conduct the tests underconditions that are controlled and as realistic as practical.6.
