Larger usage labs have an easier time justifying printing equipment investment. They save money due to benefits of patient specific information on the label. Durability Many laboratories print their own labels using xylene resistant labels and ribbons. It is best to avoid touching the surface of the label while it's wet with xylene so as to avoid any smudging of the print. Once the xylene dries the print is very durable.
Some laboratories buy labels that are already printed.
The most durable labels are protected with a clear plastic film. These labels are the most resistant to chemicals. Purchasing printed labels allows you an amazing amount of design flexibility. Colors can be used to easily differentiate labels. This method provides the ultimate in durability and the ability to record some patient-specific data on the label.
