Description of Ribbon for Near Edge Printers
What is Meant By Flat Head and Near-Edge Print Heads?
There are two types of print head: “Flat” and “Near-Edge” and so there are two types of thermal transfer ribbon. There are benefits of each technology which merits another article in its own right. One is neither “better” than the other without explanation but suffice to say, you must match your thermal transfer printer with the correct thermal transfer ribbon! For example, all Zebra printers use flat print-heads while others such as TEC, use near-edge. Avery Dennison and others produce a range of label printers that take both types, so it is essential to know which head is in your machine before you purchase the wrong ribbon. Using a flat head ribbon in a near edge printer or vice-versa, won’t dammage the printer but you won’t get very acceptable results. Beware though, you could drastically reduce your print head life by increasing print head temperature and increasing the head pressure excessively in attempt to improve print quality using the wrong type of ribbon! A false economy if ever there was one, as print heads aren’t cheap.
Over time, thermal print heads will wear out eventually and you will notice this as each element “dot” stops working, the appearance of lines (actually, non-printed lines, to be correct) will get increasingly worse. The dots are like lightbulbs – one day one will stop working and more will tend to fail afterwards. However, it is quite ok to carry on printing with an odd dot “down” unless so many are missing that either the printed output looks a mess or worse still, they affect the readability of the barcode.
To prolong the life of your print head it is essential to use a good quality ribbon with a low-friction back coating which minimises wear on the head and to also match the correct ribbon to your printer, so that you can lower the head power and reduce the pressure applied. You should of course clean your print head regularly, the frequency of which is dependent on usage and will be advised by your printer/ribbon supplier.
