What is the difference between the roll-on (inner carbon or outer carbon) of the all-resin carbon strip?

The roll direction (inner carbon or outer carbon) of the all-resin carbon strip mainly refers to the position of the toner layer in the carbon strip roll, which will have a certain impact on the performance and application scenario of the carbon strip. Here are the main differences between inner and outer carbon:

First, definition and structure

Inner carbon: The toner layer is located inside the carbon strip roll, and one side in contact with the print head is the toner layer, and the other side is the back coating. This structure allows the toner layer to be in direct contact with the print head during the printing process.

Outer carbon: The toner layer is located on the outside of the carbon strip roll, that is, the toner layer is the visible surface of the carbon strip roll, and the back is the support layer or back coating. When printing, the back coating is in contact with the print head.

Second, performance and application

1. Internal Carbon:

High quality printing: Because the toner layer is in direct contact with the print head, the inner carbon strip usually provides higher print quality, suitable for applications that require clear, fine printing results.

Wear resistance: The inner carbon strip is directly stressed by the toner layer during the printing process, so it wears faster and needs to be replaced more frequently. But this also means that it can provide better transfer results during the printing process.

Application scenario: Suitable for label printing, bar code printing and other applications that require high print quality.

2. Outer Carbon:

Printing speed: The toner layer of the outer carbon strip is located on the outside, and there is less friction when printing, so higher printing speeds can be achieved.

Cost effective: Compared to the inner carbon strip, the cost of the outer carbon strip is usually lower, suitable for large number of printing application scenarios.

Long-term storage: The toner layer of the outer carbon belt is not easy to be polluted by air and moisture, and can maintain the long-term stability of the printing quality, which is suitable for occasions that require long-term storage.

Third, identification method

Visual and tactile: the toner side of the inner carbon belt is usually black or thick, and feels rough; The toner layer side of the outer carbon strip is the outer side of the carbon strip roll, the color may be more bright (such as red, purple, etc.), and the touch may be smooth.

Test method: Internal and external carbon can be distinguished by a simple test. For example, use sticky label paper to stick on the surface of the carbon tape. If you stick black toner, this side is the toner layer. If the carbon powder layer is on the outside of the carbon strip roll, it is the outer carbon. On the contrary, it is the inner carbon.

Fourth, selection and use

When choosing the winding direction of the all-resin carbon strip, it needs to be determined according to the specific application scenario and requirements. If high-quality printing results are required and the printing volume is not large, the internal carbon strip may be a better choice. If the pursuit of printing speed and cost effectiveness, especially in the case of large quantities of printing, the outer carbon belt is more advantageous.

In general, the roll direction (inner carbon or outer carbon) of the all-resin carbon strip mainly affects its printing quality, speed, cost, and application scenarios. In the selection, should be based on the actual needs of the balance.
