ink roll is good or not?

    It is the foremost indicator to measure whether the quality of ink roll is good or not, and the differences between the ordinary ink roll and imported one as well. The critical impact on the printing times is the ingredient of ink.
The temperature (which is needed when solid ink is melting) is the key to impact the the printing times. If the temperature is very low, no matter how good the ink is,hot melt ink roll can not melt and the ink in the sponge can not be completely released
