What is the reason for the blank part in wax based carbon?

There may be several reasons for the blank part of wax based carbon ribbon:

Improper film surface treatment: During the production process of carbon ribbon, if the light film is not treated properly, it may result in blank areas on the surface of the carbon ribbon, which will appear during printing.

Uneven ink coating: The uniformity of ink coating is crucial for the printing effect of carbon ribbon. If there is unevenness in the ink during the coating process, it may cause some areas of the carbon ribbon to have no ink, resulting in a blank.

Carbon ribbon quality issues: Using inferior carbon ribbons or expired carbon ribbons may also result in blank spaces during printing.

Mismatch between carbon ribbon and paper: If the type of carbon ribbon does not match the printed paper, it may also result in poor printing quality, including the appearance of blank areas. For example, certain types of paper may require specific ribbon types to ensure good printing results.

Printer setting issue: Improper settings such as density and speed of the printer may also affect the printing effect of the ribbon. If the setting is too low, it may cause the coating of the carbon ribbon to not be fully transferred to the paper, resulting in a blank.

To solve the problem of blank areas in wax based carbon ribbons, the following measures can be taken:

Ensure reliable quality of carbon ribbon and avoid using inferior or expired carbon ribbon.

Check the printer settings to ensure that parameters such as concentration and speed are set correctly.

Choose the appropriate carbon ribbon based on the type of paper being printed.

If the problem persists, it is recommended to contact the ribbon supplier or printer manufacturer for further consultation and solutions.

In summary, the reasons for the blank areas in the wax based carbon ribbon may involve multiple aspects and require careful investigation and corresponding measures to be taken to solve them.
