Analog Hot Stamp Printing vs. Digital Thermal Transfer Printing

Thermal Transfer 'Best Buy' labels


Many marking and coding equipment sellers espouse the virtues of thermal transfer overprinters (TTO) over the capabilities of hot stamp coders. As a manufacturer of both thermal transfer and hot stamp technologies, we are here to tell you that there is room for both. The truth is that each technology excels for very different reasons.


Hot stamp printers consistently provide quality prints at very high speeds. These machines are nearly all mechanical, making service and maintenance easy and straightforward. It is very hard to break a hot stamp machine and even harder to run out of options when it comes to fixing it. Because hot stamp printers require manual adjustments in order to change print codes, they are more ideal for applications with only occasional changes to the print message. These machines tend to be low cost and more durable than TTO.


Don’t be fooled by sellers who try to tell you that hot stamps have drastically lower ribbon capacities. We have seen hot stamp ribbon capacities reported as low as 300’, yet our bestselling hot stamp – the Norwood K Series – accommodates rolls as large as 1500’. Unlike TTO technology, hot stamps perform well in both hard and flexible materials. Many of our hot stamp customers specifically choose hot stamp technology for the indelible, engraved mark it leaves behind on rigid and semi-rigid products and materials which serves as a second quality check. TTO isn’t compatible with rigid and semi-rigid substrates.


When it comes to printing graphics, linear and 2D barcodes and a variety of fonts onto flexible plastic, foil and paper labels, it is hard to beat the versatility of thermal transfer printers (TTO). These digitally driven print message machines can accommodate even the most complex of print messages. Our TTO technology features ribbon feed control capabilities and can accommodate both continuous and intermittent printing applications. TTO also provides more versatility in terms of the scalability of its print area. Our NGT TTO line up offers print areas as large as 8”x3.9” when used in intermittent mode or 8”x39” when operating in continuous mode.


Although TTO offers greater flexibility in terms of print areas and message creation, it does have its draw backs. Having fewer mechanical parts and more electronic components means that you will be replacing more parts over time rather than repairing them. Of course you have to weigh the bad aspects with the good. If you have a lot of short runs with frequent product and message changes, TTO is likely the best technology for you.


If you have any questions regarding hot stamp or TTO, feel free to reach out to one of our marking and coding experts here at Diagraph. We are happy to walk you through the best options to meet your specific application needs. Call 1-800-722-1125 to speak with an expert today!
