Web offset inks

WEB OFFSET printing has recently received a boost with the growth of the holiday advertising industry, and so the demand for better art work at competitive prices has increased. Consequently there has been a demand for low temperature waterless inks. These low‐energy saving inks have been found useful in offsetting some of the problems caused by water in the process. The use of low temperature inks has meant less drying out of the web and the need for remoisturising; it is also less costly in energy demands. Web temperatures have been considerably reduced. Also blistering problems resulting from moisture/solvent trappings between two impervious ink films can be eliminated. There is also a reduction in solvent emission proportionately together with the need for blanket washes due to reduced blanket piling.
