For bulk orders, &#8220;opacity&#8221; isn&#8217;t just a buzzword; it&#8217;s your profit margin.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"1-the-death-of-the-triple-flash\">1. The Death of the Triple-Flash<\/h3>\n\n\n\n<p>Standard inks are translucent. To get a bright red on a navy shirt, you&#8217;d typically need a &#8220;Print-Flash-Print-Flash-Print&#8221; sequence. Our <a href=\"https:\/\/plastisol-inks.com\/en_nz\/screen-printing-plastisol-ink\/\">plastisol ink<\/a> is engineered with a high concentration of Titanium Dioxide and premium pigments. This allows you to achieve full coverage with a simple &#8220;Print-Flash-Print&#8221; or, in many cases, a single heavy-flood pass.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\" id=\"2-beating-dye-migration\">2. Beating Dye Migration<\/h3>\n\n\n\n<p>When printing on dark polyester or blends, the fabric\u2019s dye can turn into a gas when heated, bleeding into your ink (turning white ink into a dingy grey). High opacity inks often feature &#8220;Low Bleed&#8221; properties that act as a chemical barrier against this migration.<\/p>\n\n\n\n<blockquote class=\"wp-block-quote is-layout-flow wp-block-quote-is-layout-flow\">\n<p><strong>Expert Insight:<\/strong> Always perform a &#8220;stretch test&#8221; post-cure.
