Reticulating Varnish

Much like the strike-through technique, a perfect pattern image trap can be achieved by the application of a special dull varnish followed by an overall application of a gloss coating. A chemical reaction occurs that neutralizes the gloss in the areas previously dull varnished. To achieve a raised, reticulating effect, the same application of gloss varnish is used to define the pattern; but with increased viscosity of the coatings, the chemical reaction causes the varnish to bead and leave a perfectly registered, visible pattern with true dimension which creates a visual and textured feel. Reticulating coating must be used on coated stock and can be applied to any process or spot color print area, but because of the contrast, application on a darker, or solid-color background is often more dramatic.
