1. Printing color difference

效果圖的顏色跟印刷之后的顏色是有一定的偏差的，我們俗稱色差。色差的存在一般在我們肉眼可以接受的范圍之內是可以的，如果出現明顯的顏色偏差那就不是色差了，而是調色問題。

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、拉伸紋

2. Stretch pattern

目前市面上的奶茶紙杯都是通過壓縮成型，杯面難免會出現不同程度的拉伸線絲，這是屬于正常的。一般肉眼看過去都能接受的情況下是屬于正常的，如果拉伸紋特別明顯的粗大，說明制作工藝不足。

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、數量誤差

3. Quantity error

在杯子制作工藝的過程當中，數量的多少是不可以保證的，難免會出現偏多偏少的情況。畢竟杯子在生產的過程都是批量生產的，中途難免也會出現幾個杯子是不合格的，不合格的杯子我們要拿出來，在生產的過程中把數量補上去，也要看當時生產這批杯子的原料等等因素。所以數量誤差的存在是在所難免，以實際數量為準。

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、重量誤差

4. Weight error

奶茶紙杯定制都是通過克重來計算單價的，但是在工廠制作的過程當中，并不能保證每個奶茶杯的克重都是一樣的，都會出現正負差的重量，就算你同時剪一段10米的繩子，他們的重量都是不一樣的，為什么會出現這樣的情況呢？因為產品的密度分布不均勻。但是，整體的重量是不變的。

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.
