2 The developer concentration is too high

3 The development time is too long

4 the risk of insurance is mainly to protect the contract user's enterprise property loss or personal injury and death risk caused by the quality defects of new materials Development temperature too high 1 Reduce exposure time

2 Diluted developer

3 Why is Jinan assay so famous? Short development time

poor solid density

1 The negative is not in close contact with the layout

2 The graphic density of the negative is not enough

3 Overexposure
