How much do you know about the characteristics of various customized leather materials commonly used in notebook printing sizes?

Among the daily office supplies, notebook is one of the most frequently used daily office supplies.
Many enterprises, governments, or schools also want to print their own notebooks with distinctive logos, but it is not clear what size and paper to choose.
Today, we will briefly introduce the basic knowledge of printing notebooks and the characteristics of various leather materials customized for notebooks.
Conventional printing dimensions for notebook printing
Size 1: 16K -- Cover specification (270 * 210mm) -- Inner core specification (258 * 188mm)
Size 2: 24K -- Cover specification (235 * 175mm) -- Inner core specification (210 * 190mm)
Size 3: 32K - Cover specification (218 * 154mm) - Inner core specification (208 * 144mm)
Size 4: 48K -- Cover specification (187 * 122mm) -- Inner core specification (170 * 97mm)
Dimension 5: 56K -- Cover specification (145 * 105mm) -- Inner core specification (128 * 83mm)
Regular binding form
Notebook printing and binding forms include: paperback, loose leaf, coil, and hardcover.
Small Knowledge: Text typesetting documents, short version loose printing with low quality requirements, can be printed using paper (zinc oxide) plates with light weight, saving printing fees, compressing printing costs, saving time, and being fast and efficient.
In addition, when printing production enterprises provide notebook printing products to users, they mainly use double adhesive tape and writing paper in terms of printing paper.
Characteristics of various leather materials customized for notebooks
There are various types of leather, and different types of raw hides and different tanning methods can be used to make leather suitable for various purposes. Leather commonly used in leather products has the following characteristics:
1. Characteristics of cow leather
Cow leather includes cattle leather, yak leather, and buffalo leather.
Yellow cattle leather has fine grain, thick skin, high strength, fullness, and good elasticity, so its products are beautiful, comfortable, and durable. Yellow cattle leather is mainly used in clothing, shoes, bags, and ball products.
The grain surface of cow leather is slightly worse than that of cattle leather, and its other properties and uses are generally similar to those of cattle leather.
Buffalo leather has a rough surface, coarse fibers, and slightly lower strength than cattle leather. Other properties are similar to those of cattle leather. Buffalo leather is mainly used for making sofas, bags, and also for making leather shoes.
2. Characteristics of pig leather
Pig leather differs greatly from cow and sheep leather, mainly in terms of rough grain, tight fiber, fullness, and poor elasticity. However, the strength of pig leather is similar to that of cow leather, and higher than that of sheep leather. Therefore, its products are durable, but have poor aesthetics.
Pigskin leather can be used for the production of various leather products.
3. Characteristics of sheepskin leather
Sheepskin leather is divided into goat leather and sheep leather.
Goat leather has a fine and beautiful grain and good softness, but its firmness is worse than cow leather. Goat leather products are beautiful and comfortable, but their surface resistance to friction and durability are general. Goat leather is mainly used for the production of high-end women's leather shoes, clothing, gloves, and women's handbags.
Sheep leather has better softness than goat leather, but its firmness is not as good as goat leather. Sheep leather products are more beautiful and comfortable to wear, but their durability is poor. Sheep leather is mainly used in the production of clothing and gloves, as well as in the production of high-end leather shoes and soft bags.
4. Characteristics of full grain leather
Full grain leather refers to leather that retains and uses the original appearance of animal skin (the hairy side), also known as front leather. Some surfaces of full grain leather are directly used without finishing, but most of them are processed through beautification and finishing.
Full grain leather requires high-grade raw leather with less damage and high processing requirements, so full grain leather is high-grade leather. Due to the fact that the surface of the raw leather remains intact on the leather, its fastness performance is good. Generally speaking, the surface of full grain leather is not coated or the coating layer is very thin, which maintains the softness and good breathability of the leather. The grain surface of genuine leather is used to reflect the natural style, making it comfortable and beautiful.
Full grain leather is mostly colored with dyes, so the industry generally refers to full grain leather with dyes as the main colorant for coating as aniline leather (or full aniline leather). This type of leather has uniform dyeing, clear grain patterns, and is not coated with any film forming substances that have a covering effect. The grain patterns on the leather surface are completely not covered and retained; The modified leather has only a very thin, colorless and transparent surface on which the grain of the leather itself can be clearly seen.
Full grain leather is used for all premium leather products. When cleaning and caring for such leather products, attention should be paid to maintaining their unique style and feel.
5. Characteristics of semi aniline leather
The raw material for this type of leather has partial but very shallow defects on the grain surface. To cover the defects while retaining the natural grain texture of the leather, a small amount of pigment and adhesive synthetic film agent and dye should be used to lightly spray dye the leather to form a semi covering layer with a very thin coating, making the grain texture of the leather invisible.
