However, there are choices in metallic ink that can optimize the me- tallic look. In this case, you will want to print using a finer particle size pigmented ink, which will aid in the transfer of the ink without piling. The increased pigment transfer equates to an improved metallic effect, as it fills all those peaks and valleys in the uneven surface. On the flip side, a smooth coated substrate will generate the highest brilliance, because the metallic pigment gets good orientation and direct reflection of the light. You are also able to transfer larger par- ticle size flakes, aiding in brilliance due to the increased surface area of the pigment. By understanding your substrate and the options available in metallic ink, you can make choices that help optimize your metallic effect. UNDERSTAND DESIGN INFLUENCE So many times design is overlooked as not having an impact on the me- tallic ink choice. Depending on whether you’re printing solids, screens or vignettes, there may be an optimized selection of metallic ink. For example: Artwork with mostly solids incorporated in the design can print cleanly with larger particle size pigments without creating dirty edges. If you are printing mostly fine line work or screens, you will benefit by selecting a finer particle size pigmented metallic ink. Yes, you may sacrifice a little brilliance, but the benefit of cleaner print due to the improved transfer using a finer line, lower BCM anilox will surpass any loss in effect. And you can’t decide the best choice here without also, as previously discussed, including what substrate will be used. Wait, let’s back up a minute! A BANDED ANILOX TEST? Have you considered utilizing a banded anilox test? This could be the most underutilized resource we have for optimizing the metallic printed effect. To show the value of a banded anilox test, we con- ducted a controlled test, taking typical anilox engravings we see used in the market versus some possible optimized choices. Here are the parameters used in our evaluation: • Mark Andy 4150 press • Harper banded anilox rolls • 10-μm. particle sized water based & UV flexo inks • Fasson semi gloss paper • Raflatac BOPP 213 uncoated film SEPTEMBER 2014 | FLEXO 57
