The post-printing processing technology of the envelope has certain characteristics. According to its product attributes, it is divided into two parts: necessary processing technology and non-essential processing technology.
1. Non-essential processing technology
This face-to-face process is mainly to increase the aesthetic appearance of the product. Common processing techniques are:
1. Laminating
It is a processing technology that coats plastic film with adhesive and bonds the printed matter with heat and pressure. After the printed matter is covered with film, due to the addition of a layer of plastic film on the surface, it is smoother, and the gloss and color firmness are also better. The graphics are bright in color and full of three-dimensional sense. At the same time, it also has waterproof, anti-fouling, and wear-resistant. Folding and corrosion resistance.
2. Glazing
A common process in high-end printed products is to coat (or spray, or print) a colorless and transparent coating on the surface of the printed product, thereby forming a thin and uniform transparent bright layer on the surface of the printed product. It not only protects the printed matter, but also changes the foreign trade texture and visual effects of the printed matter.
3. Drumming
The process is called embossing and embossing, that is, a piece of intaglio and a letterpress with a close fit are sandwiched between the printed matter, and under a certain pressure, the surface of the printed matter is formed with a graphic or pattern similar to the relief, so that the printed matter has a significant relief.
2. Necessary processing technology
Because there is a remarkable feature in the structure of the envelope, which is to have a paper pocket for loading documents (called "tongue" in the printing industry), the production of this part must go through "folding" and "pasting". Process.
1. Folding
Through mechanical action, the indentation of changing the material shape is reserved on the paper or other cutting paper to facilitate folding.
2. Paste
That is, the printed matter is bonded and formed. According to the choice of adhesive, adhesive strength, and use environment restrictions, the paste is divided into general and high-grade according to quality, two cases.
It should be noted that in general, these two processes need to be priced separately, and cannot be ignored when calculating the cost of printed matter.
Best badger are brushes made with the finer and more pliable hairs from 20 - 25% of the badger's body. It is longer in length and lighter in color than 'pure' badger hair. A 'best' badger brush is more densely filled with hair than the 'pure' badger brush and will produce a correspondingly greater lather. However, some wet shavers argue that the variance between the quality of a 'pure' and a 'best' badger brush is negligible. Best badger and better quality brush hairs are often fit so that the ends do not have to be cut to shape.Pure badger are badger hair brushes that use the most common hair from the underbelly of a badger, the hair which covers around 60% of a badger's body. This hair varies greatly in softness, pliability and color. Pure badger hair is usually dark in color, but fluctuates from a light tan to a near-black or silvery sheen. The hair is coarser than 'best' or 'silvertip' hair due to its larger shaft. Brushes made exclusively with pure badger hair cost significantly less than finer badger hair. Most often, pure badger brush hairs are trimmed to shape, resulting in somewhat stiff, rough ends.
A shave brush's price is usually determined more by its bristle load than any other factor, except for brushes with very exotic handles. The most expensive brushes often use exotic materials in the handle. The bristles are fixed together into a knot that is installed into the handle. The best quality brushes are hand knotted. Badger and boar brushes are the most commonly found animals used for Shaving Brush fibers. Badger species include the Eurasian badger and the hog badger
