Code Printing Technology<span class=\"ez-toc-section-end\"><\/span><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">QR code printing is a technology that involves installing a digital nozzle machine onto the existing production line. The machine uses electronic ink to spray patterns, and through a computer-controlled nozzle, it can alter the patterns based on predefined conditions.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Machine_Configuration\"><\/span>Machine Configuration:<span class=\"ez-toc-section-end\"><\/span><\/h3>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Digital_Sprinkler\"><\/span>Digital Sprinkler<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Various digital nozzles allow for different DPI and spraying speeds. These nozzles create patterns on the film using built-in electronic ink. We use Ricoh&#8217;s digital sprinkler, which offers fine spraying, speed, and ease of maintenance. It can achieve up to 350 DPI at a speed of 200m\/min, with a spray area of up to 30cmx60cm\u2014suitable for most flexible packaging products.<\/p>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"1270\" height=\"714\" src=\"https:\/\/www.zkprintpack.com\/wp-content\/uploads\/2025\/01\/Digital-Sprinkler-QR-Code-Printing-Technology.webp\" alt=\"Digital Sprinkler-QR Code Printing Technology\" class=\"wp-image-1214\" srcset=\"https:\/\/www.zkprintpack.com\/wp-content\/uploads\/2025\/01\/Digital-Sprinkler-QR-Code-Printing-Technology.webp 1270w, https:\/\/www.zkprintpack.com\/wp-content\/uploads\/2025\/01\/Digital-Sprinkler-QR-Code-Printing-Technology-768x432.webp 768w, https:\/\/www.zkprintpack.com\/wp-content\/uploads\/2025\/01\/Digital-Sprinkler-QR-Code-Printing-Technology-18x10.webp 18w, https:\/\/www.zkprintpack.com\/wp-content\/uploads\/2025\/01\/Digital-Sprinkler-QR-Code-Printing-Technology-1200x675.webp 1200w, https:\/\/www.zkprintpack.com\/wp-content\/uploads\/2025\/01\/Digital-Sprinkler-QR-Code-Printing-Technology-600x337.webp 600w\" sizes=\"(max-width: 1270px) 100vw, 1270px\" \/><\/figure>\n<\/div>\n<\/div>\n\n\n\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:100%\">\n<div class=\"wp-block-columns is-layout-flex wp-container-core-columns-is-layout-8f761849 wp-block-columns-is-layout-flex\">\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:33.33%\">\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" width=\"1142\" height=\"641\" src=\"https:\/\/www.zkprintpack.com\/wp-content\/uploads\/2025\/01\/Control-Computer-QR-Code-Printing-Technology.webp\" alt=\"Control Computer-QR Code Printing Technology\" class=\"wp-image-1213\" srcset=\"https:\/\/www.zkprintpack.com\/wp-content\/uploads\/2025\/01\/Control-Computer-QR-Code-Printing-Technology.webp 1142w, https:\/\/www.zkprintpack.com\/wp-content\/uploads\/2025\/01\/Control-Computer-QR-Code-Printing-Technology-768x431.webp 768w, https:\/\/www.zkprintpack.com\/wp-content\/uploads\/2025\/01\/Control-Computer-QR-Code-Printing-Technology-18x10.webp 18w, https:\/\/www.zkprintpack.com\/wp-content\/uploads\/2025\/01\/Control-Computer-QR-Code-Printing-Technology-600x337.webp 600w\" sizes=\"(max-width: 1142px) 100vw, 1142px\" \/><\/figure>\n<\/div>\n\n\n\n<div class=\"wp-block-column is-layout-flow wp-block-column-is-layout-flow\" style=\"flex-basis:66.66%\">\n<h4 class=\"wp-block-heading\"><span class=\"ez-toc-section\" id=\"Control_Computer\"><\/span>Control Computer<span class=\"ez-toc-section-end\"><\/span><\/h4>\n\n\n\n<p class=\"wp-block-paragraph\">Our self-developed software controls the QR code printing, allowing us to customize the size, content, and resolution of each QR code.
