The technical indicators of hot ink roll
A. Printing Times (also called printing life)
A. Printing Times (also called printing life)
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.
B. Using Temperature
The temperature (which is needed when solid ink is melting) is the key to impact the printing times. If the temperature is very low, no matter how good the ink is, it can not melt and the ink in the sponge can not be completely released
C. Scratch Resistance
It indicates the changes which happened when there is a friction between the printing sample and other items. It is often measured by the friction times which can entirely remove the printing sample when exerting a certain pressure on the friction of common printing sample and white paper.
D. Adhesives
It refers to the adhesive force of ink when it is printed on the film. We usually stick the stationery tape on the ink and then drawing it away to observe how many times we can totally stick off the ink.
