Lamination preserves printed graphics, doubling their outdoor life, protecting them against fading caused by UV solar radiation, and erosion by the elements. Different overlaminates can also assist with color clarity and magnification, and even produce special effects, like add a metallic sheen. No one is arguing that lamination is a crucial component of your workflow, but bringing the equipment in-house can be a daunting and sobering thought. Therefore, LeFu Laminating Machine team in order to relieve the user of this kind of trouble, developed a reversible laminator which are LF1325-B4 and LF1732-B4 flat laminator.
There’s a few different styles of laminator. What’s the difference between cold lamination, heat assist cold lamination, and hot lamination, you wonder? And secondly, there’s the price. These are large sturdy hunks of machinery, which come in a crate, and require professional installation.
The most popular (and cheapest). And for this type we recommend our LF1700-B5 and LF1700-B6 Semiautomatic Laminating Machine which is more suitable to do laminating on Board materials, PVC, acrylic, metal, glass, aluminum composite panels, KT board, MDF board…etc. These machines use rollers to apply pressure-sensitive films to your media as it’s being fed through. A must for vehicle wrap shops, who need lamination for any sort of durable long-term application, and who print on vinyl, which doesn’t react well to extremes of heat. Also good for printers with quick-drying inks like latex or aqueous, because these prints will be ready immediately for lamination, without the need of functionality provided by heat.
Such great type of laminator like LF1700-D4 Automatic Roll to Roll Heat-assist Laminating Machine with Cutters which are a boon with to printers who use solvent inks. Solvent inks permeate the surface of your media, leaving the pigment, and then evaporating as gas. This process can take 24 hours. If you wanted to cold laminate these prints, but without LF1700-D1 help you with it, you’d have to wait until the ink was completely cured and dry, or risk air bubbles from outgassing, and a hazy effect particularly showing up on dark color backgrounds called “silvering”.
Wide format heat-assist laminator as LF1700-D4, LF1700-D5...etc. In these models, a heating element warms the top roller, accelerating the process of ink drying and outgassing, so that solvent prints can be processed with quicker turnaround (an hour or two vs. a day). Heat also helps to set the adhesive quicker.
These machines use special thermal films. Commonly used by schools, for high production, both LF1700-D2 Automatic Double Sided Hot Roll Laminator and LF1700-D3 Hot Roll Laminator have a higher-start up cost, but you can achieve economies of scale with cheaper thermal laminate rolls. Not intended for certain heat-sensitive media, but excellent for applications like encapsulation and textured surfaces like UV prints.
All in all. Cold laminators use rollers to apply pressure-sensitive films to your media as it’s being fed through. Good for printers with quick-drying inks like latex or aqueous, because these prints will be ready immediately for lamination. In heat-assist laminators, a heating element warms the top roller, accelerating the process of ink drying and outgassing, so that solvent prints can be processed with quicker turnaround (an hour or two vs. a day). Heat also helps to set the adhesive quicker.
As you can see, there are a range of types to consider when choosing a laminator. Also know, that LeFu Laminator has more options available for this major capital equipment purchase.
