Lamination of documents became very popular recently. Already not only large printing houses are able to afford to buy special laminators. But to make right choice of the similar device, it is necessary to be guided by technical characteristics.
Types of laminators
All laminators can be subdivided into package and rolled. The last are often used in printing houses and the copy centers. And package will be suitable for the small companies and house use more.
Package laminators can also be classified on devices of office and professional series. Usually they are applied to lamination of documents of standard dimensions. As for laminators of office series, they have simple design and differ in low cost. In such devices heating coil usually are special hot plates or shafts. Professional laminators differ in the increased reliability and performance. They provide the highest quality of lamination. The main lack of package laminators should be considered the high cost of consumables.
Rolled laminators are good the fact that they allow to process documents of any formats. With their help it is even possible to carry out stamping by foil. But unlike package, not all rolled devices allow to carry out one-sided and bilateral lamination. But rolled laminators differ in the low cost of consumables and rather high performance. They allow to make big circulations of products. And it is possible to refer complexity and duration of their service to shortcomings of such laminators.
Criteria for selection of laminators
Some of the main criteria when choosing the laminator should consider type of heating coil. Devices with hot plates are capable to pass film through narrow slot. At the exit it pripechatyvatsya by rubber shafts. In such laminators the film can unevenly heat up, and the result will turn out very low-quality. And here laminators with waves of heating will be suitable for processing of any surfaces. Excellent lamination of glossy surfaces in this case is guaranteed. In progress of work of any laminator the document can be reeled up on shaft. Not only the device, but also the original document can be as a result damaged. If you have chosen the laminator with function of reverse, such trouble definitely does not threaten. This function is that one pressing of the button it is possible to take easily preparation back. If in the course of lamination the film of various thickness is used, it is better to get the device with adjustable temperature of shafts. As each type of film requires certain temperature.
