I does not a matter to ask so many questions, I believed that I asked much more than that.
Heidelberg does not like the Japanese press, operator need to run a speparate procedure, just 2 keys at the console, "print without vibrator" (the no of sheet need to print was pre-defined, different model has different no. of sheets). Then change the plates, after that apply the pre-inking curve. If the curve setup correctly, after certain no. of print the OK sheet would be reach.
Heidelberg has another test form for doing the per-inking curve. You need to print around 300 sheets and measure the density at every 50 sheets. By using this collected data with their own formula, then a curve can be plot.
I believed that almost all of the new Heidelberg press during installation, Heidelberg engineer should do this for the customer. I believed that the customer need to purchase the CIP/3 preset.
In German, Heidelberg Print Media Academy provide this is a part of training course. Having no idea whether the Heidelberg PMA in Shenzhen has this course or not.
At this moment I just know that this was done by Heidelberg engineer and they always telling customer this is company secret. I think they are worrying the operator just only part of the calibration and try to done it by themselves and come to the end and complain the system is no good.
