Technologies & Techniques Anilox Rolls for Dynamic Graphics Effects Precise structure and shape Meets Tight Printing Requirements By Alexander James Increasing sophistication in the label industry has created a demand for in-line and cost-effective solutions to meet the label buyer’s needs. Along with many specialty ap- plications, the requirement of the best opacity in white, while maintaining cost-efficiency has finally been met. Dynamic graphics and special effects can be created in today ’s flexographic industry using the right anilox engraving. Due to improved laser technology and the skill in application, there are a number of channeled engravings that work well for creating the high opacity whites, interesting spot varnish effects and eye-catching special effects. Not to be forgotten, the graphic demands for process and expanded gamut have increased dramatically over the last few years. The tried-and-true technology of consistent closed cell 60-degree engravings has continued to prove to be the choice of many printers, prepress houses and plate suppliers. HIGH-END GRAPHICS High-end, high definition-graphics, requires the precise ink delivery of closed cells and not surprisingly the XLT-60° hex- agonal engraving is perfect for those requirements. Gone are the days where “fade to nothing” is not possible. Today using the latest plating and prepress technology, combined with the proper anilox engraving specification, it is entirely possible to have smooth transitions where vignettes fade to nothing. Additionally, graphic reproduction continues to increase the resolution of the graphic images and thus increase lpi of the polymer, resulting in high-quality graphics being applied to a majority of today ’s products. Four-color process print- ing is now the norm and expanded gamut printing – seven- color—continues to grow. Complementing this trend, anilox requirements have moved to increased need for engravings with much higher specifications of CPI (cells per inch) – also referred to as line-screen – and bcm (billion cubic microns) – also known as volume. These 1600cpi, 1400cpi & 1200cpi, XLT-60° aniloxs all deliver very specific ink film thickness and enable the reproduction TIPS OF THE TRADE • Using the latest plating and prepress technology, combined with the proper anilox engraving specification, it is entirely possible to have smooth transitions where vignettes fade to nothing • Four-color process printing is now the norm and expanded gamut printing continues to grow.

Having the matte and gloss varnish can create increased visual depth in your graphics that allows the product to stand out. The sheen of the gloss spot varnish tends to pull that area to the eye • Choosing the anilox engravings with shallow depths and large openings will enable the scented pigments to easily flow in and out of the engravings, resulting in the desired transfer without breaking many of the encapsulations Cross section of 60-degree hexagonal anilox cell.
