The laser changes the surface, so the code becomes permanent, clear, and durable. Because nothing touches the product and&nbsp;there\u2019s&nbsp;no ink to replace, laser marking is clean, reliable, and great for&nbsp;washdown&nbsp;and&nbsp;fast-moving production lines.&nbsp;&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-navi-blue-color has-text-color has-link-color wp-elements-5a502e4b094ae74a42832e5bc3804fab\"><strong>How does a laser marking machine work?<\/strong>&nbsp;<\/h2>\n\n\n\n<p class=\"has-small-font-size\"><strong><a href=\"https:\/\/www.linxglobal.com\/en-gb\/products\/laser-coders\/\">Laser coding<\/a>\u202f<\/strong>(laser marking) machines generate a concentrated beam inside a gain medium \u2014 such as&nbsp;fibre, CO\u2082 or crystal \u2014 then steer it with fast galvanometer mirrors and focus it to a micron-scale spot on the product surface. Laser&nbsp;marking&nbsp;is achieved by removing material or a coating from the product or packaging, or by changing the surface of the substrate. In each case, the code is permanent.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-navi-blue-color has-text-color has-link-color wp-elements-92add96ebe8b737bd074759257df4902\"><strong>What is the difference between laser marking and laser engraving?<\/strong>&nbsp;<\/h2>\n\n\n\n<p class=\"has-small-font-size\">Laser marking is the placement of the information on the surface with little to no penetration. Engraving refers to placing the information with much more force to reach under the surface of the material.<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-navi-blue-color has-text-color has-link-color wp-elements-fd7df4306205430121ef6fbba3fe1089\"><strong>What is a laser coder?<\/strong>&nbsp;<\/h2>\n\n\n\n<p class=\"has-small-font-size\">A laser coder is an industrial machine that uses a focused laser beam to permanently mark products with information like dates, batch numbers, barcodes, or logos\u2014without using ink or physical contact.&nbsp;These&nbsp;laser marking&nbsp;systems&nbsp;are widely used in&nbsp;washdown&nbsp;high-speed manufacturing environments such as food, beverage, pharmaceutical, and electronics industries. Laser coders are valued for their durability, precision, and eco-friendliness, as they&nbsp;require&nbsp;no consumables like ink or ribbons.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-navi-blue-color has-text-color has-link-color wp-elements-eaa1fcec472a63d2e2f711b82e80ea1b\"><strong>Laser vs CIJ \u2013 Which is better?<\/strong>&nbsp;<\/h2>\n\n\n\n<p class=\"has-small-font-size\">Choose\u202f<strong>laser marking<\/strong>\u202fif you need:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-small-font-size\">Permanent, high-quality marks resistant to abrasion, chemicals, heat, and tampering \u2013 ideal for traceability, barcodes, and logos.&nbsp;<\/li>\n\n\n\n<li class=\"has-small-font-size\">A clean, consumable-free process with low long-term costs and&nbsp;minimal&nbsp;maintenance.&nbsp;<\/li>\n<\/ul>\n\n\n\n<p class=\"has-small-font-size\">Choose\u202f<strong>CIJ (Continuous Inkjet)\u202f<\/strong>if you need:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li class=\"has-small-font-size\">A versatile, fast&nbsp;changeover, and cost-effective solution for multiple substrate types\u2014including curved or porous surfaces.&nbsp;<\/li>\n\n\n\n<li class=\"has-small-font-size\">Lower upfront investment when permanent marking&nbsp;isn\u2019t&nbsp;critical, such as for date\/lot coding.&nbsp;<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading has-navi-blue-color has-text-color has-link-color wp-elements-10424177dba28c2744ac7a991d2ef8b9\"><strong>What materials can be marked with a&nbsp;laser&nbsp;marking&nbsp;machine?<\/strong>&nbsp;<\/h2>\n\n\n\n<p class=\"has-small-font-size\">Laser&nbsp;markers can mark substrates including film, paper, glass, metal, plastics,&nbsp;rubber&nbsp;and wood.&nbsp;Linx offers a range of laser coders each suited to specific substrates ensuring the best durable, consistent codes on each material type.&nbsp;&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading has-navi-blue-color has-text-color has-link-color wp-elements-c0841f07f0e75c1ea9f6d68af5cbb518\"><strong>What&nbsp;are&nbsp;the different type of laser coders?&nbsp;<\/strong><\/h2>\n\n\n\n<p class=\"has-small-font-size\"><a href=\"https:\/\/www.linxglobal.com\/en-gb\/products\/laser-coders\/linx-csl60\/\">Linx CO2<\/a>&nbsp;\u2013&nbsp;Printers complex&nbsp;variable data,&nbsp;barcodes&nbsp;and graphics.
