There are many types of printing out there, including the kind that MAX International uses to put logos, sense marks and such on their rolls (that’s called “flexographic”). The printer technologies used in those roll applications are two principal types: “impact” and “direct thermal.”
Impact Printing is exactly what it sounds like. Something solid like a key or a small needle (dot matrix) either hits a piece of fabric or other material that has been saturated with or coated by some form of ink (i.e. a ribbon) or provides enough pressure to activate a special coating (carbonless and self-contained).
Printing With Ribbons:
Using a ribbon usually means that you can use an inexpensive grade of paper such as form bond or tablet.
These grades tend to be available in colors as well as white.
The paper also can be easily printed both front and back with marketing material, return policies, phone numbers or any other information your customers would find useful.
Advantages of Using Ribbon technology:
- Inexpensive single-ply paper consumables
- The flexibility of visual impact of receipt (ribbons can be made with color; the pins can be programmed to execute simple line graphics
- The shelf-life of the paper is maximized (although paper may change color, imageability is determined by the ribbon ¬, not by chemical coatings)
- Technology tends to less expensive upfront to purchase
- When using carbonless papers, once the plies have been separated, neither ply can image without ink.
Ribbonless Impact Printing:
Ribbonless impact printing uses the same technology for equipment but uses one of the specialty coatings on the paper to create an image instead of a ribbon.
Advantages of using Ribbonless technology:
- No carbon is necessary for multiple plies nor must several copies be printed to obtain duplicate images.
- Consumable maintenance is reduced because there are no ribbons to change.
- A plain or uncoated sheet (e.g. a deposit slip) may be placed in front of the self-contained paper and imaged by a ribbon.
It is important to note that both ribboned and ribbonless impact technology is being utilized less and less in the US. However, it is still quite common in other countries, although there is a strong movement to direct thermal technology in most of the above-listed applications.
Direct Thermal Printing:
Direct thermal is a specialty form of ribbonless technology. It utilizes a heat-sensitive coating that, when brought in contact with a thermal printhead generates a deep black image. Here is what a thermal printhead looks like.
Advantages of Direct Thermal printing:
- There are few moving parts in a thermal printer, thus minimizing things that can go wrong.
- There is no variation of the image from the beginning to the end of a roll
- In most cases the printhead does not move, again minimizing maintenance.
- The maintenance cost and cost of replacement printheads are low
- Will perform in almost any climate or atmospheric conditions.
- Ideal for on-demand labels.
