1. Printing color difference

效果图的颜色跟印刷之后的颜色是有一定的偏差的，我们俗称色差。色差的存在一般在我们肉眼可以接受的范围之内是可以的，如果出现明显的颜色偏差那就不是色差了，而是调色问题。

There is a certain deviation between the color of the effect drawing and the color after printing, which is commonly known as color difference. The existence of color difference is generally acceptable to our naked eyes. If there is an obvious color deviation, it is not color difference, but color matching.

2、拉伸纹

2. Stretch pattern

目前市面上的奶茶纸杯都是通过压缩成型，杯面难免会出现不同程度的拉伸线丝，这是属于正常的。一般肉眼看过去都能接受的情况下是属于正常的，如果拉伸纹特别明显的粗大，说明制作工艺不足。

At present, the milk tea paper cups on the market are formed by compression. It is normal that there will inevitably be different degrees of stretch wires on the cup surface. Generally, it is normal when it can be accepted by the naked eye. If the stretch line is particularly thick, it indicates that the manufacturing process is insufficient.

3、数量误差

3. Quantity error

在杯子制作工艺的过程当中，数量的多少是不可以保证的，难免会出现偏多偏少的情况。毕竟杯子在生产的过程都是批量生产的，中途难免也会出现几个杯子是不合格的，不合格的杯子我们要拿出来，在生产的过程中把数量补上去，也要看当时生产这批杯子的原料等等因素。所以数量误差的存在是在所难免，以实际数量为准。

In the process of cup making process, the quantity can not be guaranteed, and it is inevitable that there will be more and less. After all, the cups are mass produced in the production process. It is inevitable that several cups are unqualified in the middle. We should take out the unqualified cups and make up the quantity in the production process. It also depends on the raw materials used to produce these cups at that time. Therefore, the existence of quantity error is inevitable, and the actual quantity shall prevail.

4、重量误差

4. Weight error

奶茶纸杯定制都是通过克重来计算单价的，但是在工厂制作的过程当中，并不能保证每个奶茶杯的克重都是一样的，都会出现正负差的重量，就算你同时剪一段10米的绳子，他们的重量都是不一样的，为什么会出现这样的情况呢？因为产品的密度分布不均匀。但是，整体的重量是不变的。

The unit price of milk tea paper cup is calculated by gram weight, but in the process of factory production, it can not be guaranteed that the gram weight of each milk tea cup is the same, and there will be positive and negative weight differences. Even if you cut a 10 meter rope at the same time, their weight is different. Why is this? Because the density distribution of the product is uneven. However, the overall weight is constant.
