What are the common quality problems of wax-based carbon strips?

As a kind of printing consumables, the common quality problems of wax-based carbon strip mainly include the following aspects:

First, physical form problem

1.Carbon with needle eyes (bubbles) :

Cause: Because the ink is not evenly coated.

Impact: It will lead to incomplete pattern or text when printing, affecting the printing effect.

2.Carbon band wrinkle:

Reason: Usually due to slitting tension control system problems.

Impact: A small area of the carbon belt may not print text or patterns, because the melting temperature of the two layers of carbon belt is much higher than the temperature of the first layer, and the wrinkled part may not melt enough to complete the printing.

3.Insufficient carbon strip length:

Cause: It may be a measurement error in the production process or negligence in packaging.

Impact: It directly leads to a reduction in the amount of printing, an increase in the frequency of replacing the carbon belt, and an increase in the cost of use.

4.Paper core inner diameter tolerance problem:

Reason: the tolerance of the inner diameter of the paper core is too large or too small.

Impact: Too large inner diameter may lead to the carbon belt cannot be firmly installed on the printer, and too small inner diameter may not be able to smoothly load the printer, affecting the use of.

5.Paper core running edge:

Cause: Deviation in the process of making or installing the paper core.

Impact: May cause the carbon strip to break during operation, or the edge part cannot be properly recognized by the printer.

Second, material quality issues

1.Carbon band blank:

Cause: caused by improper processing of light film.

Impact: The printed content will appear blank parts, affecting the integrity and aesthetics of the information.

2.Material composition problem:

Reason: shoddy, wax component is too high and resin component is too little.

Impact: Can not give full play to the advantages of the mixed base carbon strip, may lead to poor printing effect, such as scratch resistance, chemical solvent resistance decline.

Third, transportation and storage issues

1.Transport temperature problem:

Cause: Improper temperature control during transportation, and the temperature is too high.

Impact: It will cause the carbon belt to stick together and be difficult to separate, affecting normal use.

2.Improper storage conditions:

Although the specific impact of storage conditions on the quality of the wax-based carbon strip is not directly mentioned, in general, the storage environment should be dry, cool, and dark to prevent moisture, aging, or deformation of the carbon strip.

To sum up, the common quality problems of wax-based carbon belts cover many aspects such as physical form, material quality, transportation and storage. In order to ensure the printing effect and the service life of the carbon strip, the user should pay attention to check its quality condition when selecting and using the wax based carbon strip, and follow the correct storage and use methods.
