Normally our other customers will order pre-production samples before the mass goods. After you approve the pre-production samples, we will produce according to the samples and your updated file. 
During the production process, we will have internal QC to check the raw materials/printing effect/surface treatment/product structure/packaging. After the completion of production, we will send you product pictures and video for double confirm before shipment. 
Or you can arrange a third-party inspection company to inspect the goods.

We can provide available sample notebooks for evaluation at your expense. Custom samples can also be ordered—please share your specific requirements.

Yes, we can. Please share your notebook designs, ensuring the artwork files are in vector format (AI, PDF, EPS).
