Make sure that the fountain solution dosing unit is working well. If you use the same ink and fountain solution on all other presses wothut any problems, it has to be the pH, and conductivity of the "juice" on your press, if the rollers are set right. Please make a gallon of press ready fount manually and check the pH, conductivity of the fresh mix in tank and compare numbers. Also check the temperature of your fount tank.
