Ink in winter

My machine man use ink reducer in winter but I see matt effect and not good finish at all please help that what should we do in winter as per ink is concern and we are using heidelberg

 

If you have ink temp controll on your press , turn the temp up or switch the system off - if it is cold , you may not need it working.
if the press has no ink temp controll , and it is too cold for the ink , short runs and no time for ink to get to right temp ' (about 30 deg' on the form rollers) , resulting buy think ink that is hard to work with , then it is about ti,e to heat your pressroom ....
Ink reducer is not a solution to the cold ink

 

you could keep ink storage area warm, or perhaps stack some cans over the delivery grate so that the IR dryers warm the ink up a bit before putting in fountain. This should reduce your need to reduce the ink as much.

 

is there any standard formula for estimating offset ink consumption?

 

I agree with him. you must have ink temp controll on your press, and then turn the temp up or switch the system off - if it is cold
