What about the paper you used for hardcover books

For the cover, we usually used the 157gsm glossy/matte coated paper mounted a greyboard. For the inside pages, it usaully has two different paper: coated paper or uncoated paper.If you want the coated paper, we suggest you to use the glossy or matte coated paper. If you want the uncoated paper, we suggest you to use the offset paper. Of course the paper weight is totally according to your requirements.
