Offset printing uses inks that, compared to other printing methods, are highly viscous.There are many types of paste inks available for utilization in offset lithographic printing. These include heat-set, cold-set, and energy-curable (or EC), such as ultraviolet- (or UV-) curable, and electron beam- (or EB-) curable. Siegwerk Offset Ink Matching With our Exclusive set-up with Siegwerk, we offer the exact shade & finish as per your requirement. For this we use a Photo Spectrometer, which analysis and projects the best matched color.

A screen is made of a mesh stretched over a frame. A stencil is formed by blocking off parts of the screen in the negative image of the design to be printed; that is, the open spaces are where the ink will appear on the substrate. Before printing occurs, the screen must undergo the pre-press process, in which an emulsion is scooped across the mesh and the 'exposure unit' burns away the unnecessary emulsion leaving behind a clean area in the mesh. The screen is placed atop a substrate. Ink is placed on top of the screen, and a squeegee is used to push the ink through the holes in the mesh.

The Screen printing process being one the oldest & most efficient methods used around the globe requires the right ink, equipment and skill.
