1. Letterpress Printing

There are many words, few photos and pictures, there are many chances of changing the tex. And the number of prints is not large-hundreds or thousands of prints should be printed in letterpress. The number of type printing should not exceed 30,000. And the fine picture electronic version should not exceed 70,000 or 80,000. Printed pictures must use pink paper to get the perfect dot. So you can’t use cheap paper to print pictures and hope to achieve exquisite results. When using the letterpress flat version of the table. The intersection of the lines is easy to separate and disconnec, which is a common short coming. Besides, when the printing pressure is too high or the surface of the pressure cylinder is too soft during printing. The back of the printed sheet of the finished product will have embossed protrusions. Which will greatly reduce the quality of the printed product.

2. Offset printing

The biggest difference between offset printing and letterpress printing. Is that letterpress printing screen images must use smooth surface paper. but offset printing does not have this need, as long as the paper is not too rough.

That is, it does not need a wetting system, so it is called “dry offset printing”.

Generally speaking, the more pictures need for book printing. The larger the picture area, the more suitable for offset printing rather than letterpress printing. As mentioned above, the effect of printing pictures with offset printing is better than that of letterpress printing. Thus, general color printing and four-color printing use offset printing instead of letterpress printing.
