Solid ink
open-in-new
<p>Solid ink (also known as hot melt ink) is a type of <a href="/facts/Ink/Y7Wj0YQS">ink</a> used in <a href="/facts/Printer_(computing)/PnDF2QuF">printing</a>. Solid ink is a waxy, resin-based polymer that must be melted prior to usage, unlike conventional liquid inks. The technology is used most often in graphics and large-format printing environments where color vividness and cost efficiency are important. </p>
