There are CD label makers which are also good for printing labels for other purpose too. Some of them were connected to the computer and the designs are made in computer and the commands are given to print the appropriate designs. Also some of them have keyboard and screen built in it which does not require any computer to connect with it. CD label maker are different from the normal computer printers. It has special mechanism to handle the rolled adhesive paper on which CD labels are printed.
Common connectivity for CD label maker is RS-232 serial port, Universal Serial Bus, parallel port, Ethernet or any sort of wireless media. To make any labels the CD label maker requires a range of materials for the development like adhesive paper, synthetic polymer (plastic) materials. There are various types of mechanism used like thermal, impact and laser but thermal mechanism are most commonly used. Two types of thermal which are direct thermal and thermal transfer type.
The direct thermal type uses heat sensitive paper which is similar to thermal fax paper. When using this technology, it tends to fade within 6 to 12 months time more over if exposed to heat, direct sunlight or chemical contact is made the life of the art on the CD label shortens. Therefore direct thermal technique is used when the requirement for the label is for the short period of time.
The second form of mechanism is thermal transfer uses heat to transfer ink from the ribbon on to the label for a permanent print. There are three forms of ribbons used in thermal transfer technique which are wax, wax / resin and only resin. Wax works great with smudge resistance and it's good for matte and semi glossy paper labels. Wax and resin are good for smudge resistance, semi glossy paper and some synthetic formats too. Resin is scratch and chemical resistance and it good for coated synthetic CD labels
When a CD label maker is continuously working there are situation when the print may shift from the actual location and this may vary from label to label. To ensure perfect area where the print has to take place from the media high quality label maker have a sensor for this which detects the fault of gap, Line, notch perforation between labels. This allows the label maker to adjust the input of label stocks so that the printing is done properly over the labels without any error.
There are label maker applicators which automate the processing of label making. These systems are used commonly in industrial and warehousing area where requirement of label printing is done is mass. The software which runs on normal computers is built to create designs and formats for labels. This software supports the general operating system and the drivers of the machine.
There are label makers which print the label and same time encode them with a RFID (Radio Frequency Identification).
