Frequently Asked Questions Regarding Laminating
At Daige, we specialize in laminating materials, from the actual adhesive to the machines themselves, we provide it all. Laminating is a method of finishing printed graphics by applying an adhesive film. These films can either be applied with a liquid laminate, or a cool laminate, both of which provide your print with a color enhancement and a greater durability that adds both value and longevity to the graphic.
With that being said, laminating is one of the top ways of finishing a print. What many don’t realize is that there are multiple ways of applying a laminate finish, and there are several different adhesives to choose from. To better help you understand the lamination process and what products fit your needs; we’ve compiled a list of the most frequently asked questions we receive.
10 FAQs About Laminating
- What’s the different between mounting and laminating? Well, laminating is the process of adding a layer of protection or a desired look to your print. When you mount aprint, you’re simply applying the image to a more rigid substrate.
- What is the difference between pressure sensitive and heat activated film? If you want to have a more permanent bond and spend less money, then heat activated filmwould be better for you. Sometimes, a print may be sensitive to heat or have adhesion problems, if this is the case, then you’ll want to use pressure sensitive film, which is a cold application.
- What are the advantages of water based adhesives? Water based adhesives are suitable for both adhesive films as well as lamination, and they’re offered at a lower costthan a solvent.
- What’s so great about a solvent based adhesive? Adhesives that are solvent based can be used for both long term applications and outdoor use because the adhesiveincludes a high level of UV protection.
- How would hot melt adhesive benefit me? It’s not affected by moisture during the application, it’s low cost, and has a high adhesion level. However, it only works forshort term outdoor use.
- What is “shrinkage” and how does it affect my print? Shrinkage is a common term because it can occur with adhesives as well as laminates. There are two reasons as towhy this would happen. First, there could have been too much heat applied during the application, and second there may have been excessive tension. Both of these instances create “stretching,” and once the graphic looks finished, you’ll notice shortly after that the graphic is pulling away from the laminated edges, and this is what creates the appearance that the image has shrunk.
- Why won’t the laminate stick to my print? There are four general reasons as to why the laminate may not be sticking to the image. First, the laminate isn’t compatiblewith the print. Second, the temperature during the application wasn’t hot enough. Third, there wasn’t enough pressure applied. Fourth, the print was still wet during the application process.
- Can I roll my print up once it’s finished being laminated? You can roll up a print without it tunneling, yes, BUT you want to give it 24 hours to cure. If you don’tgive the image and laminate time to set, then a separation could occur between the print and adhesive. Also, make sure to roll it printed side out.
- Why should I use PVC film? If you’re looking to coat a vinyl media’s and substrates, then PVC is the film you want to use. It’s a vinyl based film that offers highlevels of UV protection and it’ll provide your media with similar rates of contraction and expansion.
- How can polyester film benefit me? Polyester films are durable and stable. They’re often used to achieve a glossy lamination and they’re actually known to achieve thehighest gloss level that’s available. They also have a very high melting point, but that’s just a fun fact for the application process.
