However, glossy finish and certain metallic effects may still favor solvent or UV systems.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q2: Will switching to water-based ink require new equipment?<\/strong><br>Often, you\u2019ll need dryer upgrades and possibly improved web-tension control. For older lines, investment is likely; for newer presses, conversion is generally easier.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q3: Are water-based inks safe for food-contact printing?<\/strong><br>Low-migration water-based inks exist, but require validated migration testing and DoC. Always request lab reports matching your substrate and process.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q4: Which ink system better supports recyclable packaging?<\/strong><br>Generally, <strong>water-based ink<\/strong> is friendlier for recyclability, but final compatibility depends on varnishes and coatings. Validate with recyclers.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Q5: What documentation should buyers request?<\/strong><br>Layer-specific DoC, migration test reports, VOC measurements, and independent recyclability\/EPD data where available. Insist on press-trial samples.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><\/p>","protected":false},"excerpt":{"rendered":"<p>Choosing the right ink system for roll stock film printing is a technical decision that affects product quality, regulatory compliance, and total cost of ownership.
