The main division is cold printing, where the paint is fixed by soaking into paper.While the 'hot' offset where the printed paper web passes through the drying tunnel. The classic offset (water) is associated with the use of water rollers and hydrophilic and hydrophobic surfaces, however, this method is already abandoned due to the difficulty in obtaining a good balance of water and oil paint. The successor of this method is anhydrous offset printing where silicone molds are used instead of water.

Well, since the last 50 years (even hundreds of them), it's all about printing - books, leaflets, business cards, even shirts, mugs, pens ...
printing and marketing is an inseparable couple.
Because you can print everything on your T-shirt and have it originally.
Well, who would prohibit the rich? .
