Defective products investigation report
The description of defective products
On Jan. 6th2013, 809 cartons (405000 pieces) of plastic bags were sending to ***Shanghai company, among which 407 cartons (244200 pieces) of plastic bags were small size and the rest were large size. The plastic bags have reached ***Japan company. Customer has now detected 120 pieces of defective products with red ink on the white edge.Meanwhile, they have detected 1/3 serious plate shifting defective products when spot-checking (the detailed quantity is unknown for products were without fully inspection) :
The first problem: the defective products with red ink on the white edge; the second problem: serious plate shifting defective products.
The analysis about cause of defective products
1. The cause of the first problem:
The situation that the ink of the other colors sticks to the white edge will show up in the process of printing because of four-color overlay gravure printing. But normally the operators will pick them out when making bags.
The bags with ink had not been picked out because of the ignorance of bag cutting operators and checkers.
2. The cause of the second problem:
The plate shifting emerges in the process of printing because of four-color overlay gravure printing and the extremely small font. Our operators and checkers will pick out the serious plate shifting bags when bag-making. But since we donot check one by one, some of them will arise in the mass production.
Improvement measures
For the first problem:
We will improve the demand on bag-making operators and checkers to pick out
defective products in time as far as possible.
For the second problem:
This problem is hard to avoid. The sample plastic bags of small size we received from Japan also have the phenomenon of plate shifting, which makes it clear that it is too difficult to completely avoid plate shifting in this artwork. We have also consulted printing company who says that we can only completely avoid this problem by changing the background color into a spot color. Otherwise reproducing the products can't make the result any difference.
So we suggest that we take the following measures:
1) Taking customer's sample as the inspection standard (the sample has sent back to the customer).
If the printing of our products is poorer than that of the sample, we agree to regard them as waste products and we will reproduce them free of charge. On the contrary, we will regard them as quality products.
2) The large quantity of mass production makes it difficult to check the products one by one, so there is the existence of defective products rate. We hope that customer can allow us to have 2% of defective products rate.
