Any business that is worth the mettle will at one time require the use of fast and accurate identification. And this is where the use of bar codes, RFID, and signature capture becomes more relevant. These processes are either achieved through labelling or marking. The labelling is done through various methods while the marking also has its techniques. Marking is done through techniques such as use of laser marking machines, dot peen machines and inkjet machines.
These machines employ different tactics that are specified for various surfaces and functions. The processes of labelling and marking are important to the running of affairs at various organisations through easy identification. Dot Peen Marking This would be one of the best ways used in creating permanent ID marks; simply put thermal printing is the process that uses heat to generate markings that makes labels. This kind of method is widely used in creating barcodes.
The advantages of using this kind of printing is that low equipment is used and there is convenience, durability and flexibility in creating markings using this method. The method can be divided into two major categories; direct thermal and thermal transfer. You can click here to learn more about Dot Peen Marking Machines. Direct thermal printing is whereby a specially treated paper is passed over a print head that is heated so that it may change color which is usually to black.
Now the label forms after the paper passes under the head and receives exposures to the heat form. The benefit accrued to using direct thermal printing is that it is cost effective. This method doesn’t require use of a lot of equipment and thus saves on costs. And also there is no ribbon that is required in this kind of printing and thus the user is able to avoid any issues that may arise from using ribbons. One of the disadvantages of the direct thermal printing is that it is only used on substances that are reactive to heat. In that case most of the labels made through this method tend to fade over time especially if they are exposed to heat –they usually turn black.
This kind of method is popular on labelling perishable goods because of the nature of the labels. In short, the labels will degrade along with the perishable goods such as meat and vegetables and thus it will not have significant change on the process. On the other hand thermal heat transfer is a method that uses a ribbon to that is subsequently burned and the label is stuck on the necessary material. Now, the method of thermal heat transfer uses a ribbon that is heated or “burned” and is subsequently onto the label. The method is widely used because of the advantages it has over the direct thermal printing. When it comes to permanent markings on hard surfaces, the business employ different kinds of marking techniques which includes dot peen marking machines, laser marking machines and inkjet marking machines.
These three methods seem to make more permanent markings that stick on the surface for a long time except in inkjet printing where the marking might fade over time. Laser marking is well adapted to printing various hard surfaces including metal, plastics and ceramics. The inkjet marking is best suited to mark some of the light materials such as fabrics and so on. Learn more about laser marching machines on the Nichol Website here.
