Causes of coating failure in wet printing photography

There may be several reasons for the failure of painting in wet printing photography:

1. Improper selection of paint: the paint used may be incompatible with wet printing materials or the quality does not meet the requirements. Different types of wet board materials need to use corresponding coatings. If the wrong coating is selected, the painting result may be unsatisfactory.

2. Inadequate preparation of wet board surface: Before painting, the surface of wet board should be properly cleaned, polished and polished to ensure that the paint can be firmly attached. If the surface of the wet board is not completely prepared, the paint may not adhere to the wet board, resulting in paint failure.

3. Incorrect painting construction skills: The construction skills in the painting process will also affect the painting effect. For example, we should pay attention to the coating thickness of paint, the selection and use of painting tools, and the control of drying time. If the technology is not correct, it may lead to uneven painting, missing painting or blistering.

4. Environmental factors: Environmental factors in the painting process may also affect the painting effect. For example, high temperature or humid environment may cause the coating to dry too fast or too slowly, which may affect the coating effect.

It should be noted that the specific reasons for the failure of wet printing photography painting may vary according to the situation. In case of paint failure, it is suggested to carefully check the compatibility between paint and wet board material, ensure that the surface of wet board is fully prepared, master correct construction skills and pay attention to the influence of environmental factors. If the problem persists, you may need to consult a professional wet board photographer or technical support.
