Direct thermal and thermal transfer printing are two of the most common technologies used by printers. Direct thermal printers use heat to activate a chemical on the label or tag, while thermal transfer printers use heat and ink ribbon to create printed image on the label.
Direct thermal printing uses heat to activate a chemical on the label or tag
Direct thermal printing is a process that uses heat to activate a chemical on the label or tag. The chemical reacts with the heat to produce an image, or in some cases, text. This method of printing is commonly used for labels and tags on packaging materials such as grocery bags and boxes; however, it can also be used for tax stamps and other types of labels as well.
Thermal transfer printer uses heat and ink ribbon to create printed image on the label.
A thermal transfer printer uses heat and an ink ribbon to create the printed image. The ink ribbon is a long, thin piece of plastic with ink on it. It is fed through the printer and heated by a print head until it melts into the label material.
Advantages of direct thermal printing
There are many advantages to direct thermal printing over thermal transfer, including:
- Durability. In general, direct thermal labels are more durable than their thermal transfer counterparts. They're also waterproof and can withstand extreme temperatures. This makes them great for identifying items that will be exposed to a lot of wear and tear (such as tools or items in a restaurant kitchen), or for labeling items that need to be protected from water damage (such as food containers).
- Cost effectiveness. Another major benefit of direct thermal printing is that it doesn't require ink or toner, so there's no need for expensive cartridges! This means less waste each time you print up a batch of labels; plus, because they don't use any consumables like ink cartridges do (which means no worrying about which cartridge goes with what printer), they're easier on your budget too! Once you've invested in your equipment purchase(s), everything else will come out ahead once again thanks to lower operating costs compared against other printers' running costs—there's really nothing else quite like this feature available anywhere else right now!
Disadvantages of direct thermal printing
Images printed on direct thermal labels are not as sharp as those printed on thermal transfer labels. This can be a problem if you're trying to produce or sell products that require an exact reproduction of the original artwork. However, many businesses prefer the look and feel of direct thermal labels because they have better definition than other types of paper-based labels.
Another disadvantage of direct thermal printing is that they are heat sensitive and will fade in 6-12 months depending on environmental conditions such as light exposure or heat exposure (such as leaving your printer running constantly). Also note that direct thermal printers only print in black; there are no color options available with this type of printer.
Advantages of thermal transfer printing
Thermal transfer printing has several advantages over direct thermal printing. The most notable are a longer shelf life, better image quality and the ability to print in multicolors.
- Longer shelf life: Because the ink is transferred from one layer of paper to another rather than directly applied to the surface, thermal transfer prints are less susceptible to fading or smudging because they don't contain solvent-based dyes like direct thermal prints do. This means they can be stored for longer periods without degradation in quality.
- Better image quality: The other advantage is that with thermal transfer printing you get greater contrast between light and dark areas of your design because you're using different colors on each side of your label or tag instead of just one color like with direct thermal printers (where black is normally used). That makes it easier for customers to see what's written on your labels at a glance -- especially if these labels end up being displayed under bright light conditions such as sunlight outside or fluorescent lighting indoors!
- Multicolor printing: One of the biggest advantages is that you can print in full color with thermal transfer printers. That means instead of just using one or two colors on your label, you can use a whole spectrum (although this will increase the cost).
Disadvantages of thermal transfer printing
- Thermal transfer printing is not a recyclable process. If the ribbon used for labeling your product is not reusable, it will be difficult to recover and reuse this material.
- Ribbon costs are usually higher than direct thermal labels, as they're more complex to manufacture.
- Thermal transfer ribbons must be matched closely with their corresponding media substrates; if they're not matched properly, they may not stick well or transfer properly onto the substrate. This can lead to poor print quality and wasted time troubleshooting problems in production if you don't choose compatible materials that work together well.
How to choose the suitable printer?
Direct thermal labels are best used for short run label printing and barcode applications. They are most often used for shipping labels, receipts, address labels, thank you stickers, etc.
Thermal transfer labels are best used for high volume printing. They can be printed on rolls or sheets and typically have a permanent adhesive backing. These labels are typically used in machine labeling such as warehouse shelf labels or chemical labels.
With the right equipment and materials, you can have complete control over your printed products. If you run a small business that doesn't require a high volume labels, and also consider saving costs on printing, you are highly recommanded to get MUNBYN thermal shipping label printer. We can help you choose the perfect solution for your needs.
