Water pick up plays the key role in achieving superior lithographic print quality and press performance. The main aim of this test is to maintain proper ink water balance during entire process of printings. With the help of Lloyds Inkoscope 92-SAV ink maker can easily formulate and determine well in advance the effect of the fountain solution on the inks various components chemo-physical behaviour.
The system incorporates advanced microprocessor based water dispensing system to allow ink maker to perform range of test and accurately evaluate the effect of fountain solution on ink formulation. The emulsification unit dispenses measured amount of damping solution to the roller system of the Inkoscope where it gets emulsified with the ink. The indepth study of damping solution effect on ink tack can be observed on line on computer monitor by evaluating the curves of running tack with time.
(Refer test graph no. 4, 4A & 4B from product catalogue).
The compact and very simple to use Lloyds lithographic unit allows the ink maker to perform endurance test, (See test graph no. 5, 6 & 7) in which the ink can be treated with fix amount of water at preset interval of time, the results obtained by this test allows the user to evaluate and interpretate effect of damping solution and composite behaviors of various components of the ink for perfect ink water balance. Thus allowing the ink maker to perfectly formulate error free ink to achieve superior and consistent quality lithographic printing production.
