To understand the specific differences between the two in printing, we need to analyze them from four dimensions:
Trade books: usually use ordinary paper such as offset paper, white newspaper or writing paper, which is cheaper, but the paper quality is average and the printing effect is relatively poor.
The gram weight is usually between 70-128 grams. Lighter paper is suitable for making dictionaries, manuals and other books, while heavier paper is suitable for making textbooks, reference books, etc.
The gram weight is usually above 128 grams, and can even reach 300 grams or higher. High-gram paper can provide a thicker touch and better show the texture and grade of the artwork.
Trade books surface finish is usually simple , and common ones include coating, calendering, etc. to improve the whiteness, smoothness and glossiness of the paper.
Art books surface finish is more diverse. In addition to sizing and calendering, coating, glazing, embossing and other treatments may also be performed to obtain different visual effects and touches , such as matte, glossy, suede, etc.
Due to the average quality of the paper and relatively poor color expression, the printed images may not be bright and full enough.
Due to the use of high-grade paper and special surface treatment, the color expression is more outstanding , the printed images are more vivid, fuller, and more layered , and can better restore the colors of the artworks.
