牛皮紙的印刷特性

　　Printing characteristics of kraft paper

　　通常牛皮紙有兩種基本顏色，棕色和白色。白紙經(jīng)過(guò)化學(xué)技術(shù)漂白，通常用于印刷，而棕色牛皮紙用于更多包裝。白色牛皮紙包裝具有健康安全、環(huán)保、性?xún)r(jià)比高等諸多優(yōu)點(diǎn)。它完全采用木漿生產(chǎn)，來(lái)自人工林場(chǎng)而不是天然林，白色牛皮紙可回收再利用。

　　Usually, kraft paper has two basic colors, brown and white. White paper is bleached by chemical technology and is usually used for printing, while brown kraft paper is used for more packaging. White kraft paper packaging has many advantages such as health, safety, environmental protection, and high cost-effectiveness. It is entirely produced using wood pulp and comes from artificial forest farms rather than natural forests. The white kraft paper can be recycled and reused.

　　牛皮紙印刷工藝

　　Kraft paper printing process

　　一個(gè)顏色中如果同時(shí)有大面積的實(shí)地和網(wǎng)點(diǎn)(或很細(xì)的線條)，那就最好把實(shí)地和網(wǎng)點(diǎn)(或很細(xì)的線條)分成兩個(gè)版來(lái)印。要不然的話，實(shí)地部分印實(shí)了，網(wǎng)點(diǎn)(或線條)就容易印糊，網(wǎng)點(diǎn)或線條印清楚了實(shí)地部分又容易漏白，如果對(duì)印刷效果要求嚴(yán)格的話，兩者就很難兼顧，所以需要分成兩塊印版來(lái)做。

　　If there are large areas of solid and dotted lines (or very thin lines) in a color, it is best to divide the solid and dotted lines (or very thin lines) into two versions for printing. Otherwise, if the solid part is printed, the dots (or lines) are easily blurred, and if the dots or lines are printed clearly, the solid part is prone to white leakage. If the printing effect is strictly required, it is difficult to balance the two, so it is necessary to divide them into two printing plates for production.

　　牛皮紙因其特殊的紋理和質(zhì)感，成為了設(shè)計(jì)師非常喜歡使用的材料之一。在印刷牛皮紙時(shí)，需要注意以下幾個(gè)方面:1、印刷設(shè)備的選擇:牛皮紙的表面比較粗糙，需要選擇適合的印刷設(shè)備，一般推薦使用凸版印刷機(jī)或柔性版印刷機(jī)。印刷過(guò)程中，需要控制好協(xié)調(diào)輪和壓力輪的壓力，以確保印刷效果清晰。2、印刷色彩和圖案設(shè)計(jì)的技巧:牛皮紙表面的皺紋和紋理會(huì)對(duì)印刷效果產(chǎn)生影響。在設(shè)計(jì)時(shí)，需要根據(jù)牛皮紙的表面特點(diǎn)進(jìn)行設(shè)計(jì)，避免過(guò)于復(fù)雜的圖案或細(xì)節(jié)。

　　Kraft paper has become one of the materials that designers love to use due to its unique texture and texture. When printing kraft paper, attention should be paid to the following aspects: 1. Selection of printing equipment: The surface of kraft paper is relatively rough, and suitable printing equipment should be selected. Generally, it is recommended to use a relief printing machine or a flexographic printing machine. During the printing process, it is necessary to control the pressure of the coordinating wheel and pressure wheel to ensure clear printing results. 2. Techniques for printing color and pattern design: Wrinkles and textures on the surface of kraft paper can affect the printing effect. When designing, it is necessary to design according to the surface characteristics of kraft paper, avoiding overly complex patterns or details.

　　3、常見(jiàn)的牛皮紙印刷效果:常見(jiàn)的牛皮紙印刷效果有燙金、燙銀、壓紋、鼓凸等。這些效果的出現(xiàn)需要在印刷時(shí)控制好溫度和壓力，以及合適的印刷油墨。

　　3. Common kraft paper printing effects: Common kraft paper printing effects include hot stamping, silver stamping, embossing, bulging, etc. The emergence of these effects requires controlling the temperature and pressure during printing, as well as appropriate printing ink.

　　牛皮紙的種類(lèi)   牛皮紙通常保持其黃褐色之本色，適合作袋子和包裝紙等。依性質(zhì)與用途的不同，牛皮紙又有各種不同的用途。牛皮紙系一種紙的統(tǒng)稱(chēng)，并沒(méi)有一定的規(guī)范，一般根據(jù)其性質(zhì)和用途的不同加以分類(lèi)。按照顏色的不同可以分為:原色牛皮紙、赤牛皮紙、白牛皮紙、平光牛皮紙、單光牛皮紙、雙色牛皮紙等。按照用途的不同可以分為:包裝牛皮紙、防水牛皮紙、防潮牛皮紙、防銹牛皮紙、打版牛皮紙、制程牛皮紙、絕緣牛皮紙板、牛皮貼紙等。按照材質(zhì)的不同可分為:再生牛皮紙、牛皮芯紙、牛皮原紙、粗面牛皮紙、牛皮紙、木漿牛皮紙、復(fù)合牛皮紙等。牛皮紙?jiān)牧蟻?lái)源不同，生產(chǎn)批次不同，生產(chǎn)季節(jié)不同，生產(chǎn)機(jī)器機(jī)臺(tái)不同，等等很多原因都會(huì)影響到牛皮紙卷筒原紙的顏色不一樣，這種顏色的不一樣很難避免的，而且無(wú)法控制，一般同一批次牛皮紙可以保證98%顏色一致。

　　What are the types of kraft paper    Kraft paper usually maintains its natural yellow brown color and is suitable for use as bags and packaging paper. According to their properties and uses, kraft paper has various purposes. Kraft paper is a general term for a type of paper that does not have a certain standard and is generally classified based on its properties and uses. According to different colors, it can be divided into: primary kraft paper, red kraft paper, white kraft paper, flat kraft paper, single gloss kraft paper, two-color kraft paper, etc. According to different purposes, it can be divided into packaging kraft paper, waterproof kraft paper, moisture-proof kraft paper, rust proof kraft paper, printing kraft paper, process kraft paper, insulated kraft paper, kraft stickers, etc. According to the different materials, it can be divided into recycled kraft paper, kraft core paper, kraft base paper, rough kraft paper, kraft paper, wood pulp kraft paper, composite kraft paper, etc. The different sources of raw materials, production batches, production seasons, production machines, and many other reasons can affect the color of kraft paper rolls. This color difference is difficult to avoid and cannot be controlled. Generally, the same batch of kraft paper can ensure 98% color consistency.

　　牛皮紙與漂白紙的區(qū)別

　　The difference between kraft paper and bleached paper

　　與漂白紙相比，牛皮紙有許多獨(dú)特的優(yōu)點(diǎn)。對(duì)于居家食品的包裝，如燒烤食品或家常食物，牛皮紙自然的褐色使包裝看起來(lái)溫馨、懷舊。木質(zhì)裝潢為主體、帶鄉(xiāng)村氣息的牛排餐廳，外賣(mài)食品包裝用牛皮紙，即使不在餐廳用餐也能感受到餐廳的風(fēng)格。單是牛皮紙獨(dú)特的外觀，也比整體是白色的包裝 更顯突出。

　　What    Compared to bleached paper, kraft paper has many unique advantages. For home food packaging, such as barbecue or home cooked food, the natural brown color of kraft paper makes the packaging look warm and nostalgic. A steak restaurant with wooden decoration as the main body and a rural atmosphere. The delivery food packaging is made of kraft paper, and even if you don't dine in the restaurant, you can feel the style of the restaurant. The unique appearance of kraft paper alone is more prominent than the overall white packaging.

　　牛皮紙與紙袋紙的區(qū)別

　　What is the difference between kraft paper and paper bag paper

　　紙袋紙類(lèi)似于牛皮紙，大多以針葉木硫酸鹽漿來(lái)生產(chǎn)，國(guó)內(nèi)也有摻用部分竹漿、棉桿漿、破布漿生產(chǎn)的，因此紙袋紙機(jī)械強(qiáng)度很高，一般用來(lái)制作水泥、農(nóng)藥、化肥及其它工業(yè)品的包裝袋。為適合灌裝時(shí)的要求，紙袋紙要求有一定的透氣性和較大的伸長(zhǎng)率。

　　Paper bag paper is similar to kraft paper and is mostly produced from coniferous wood sulfate pulp. In China, some bamboo pulp, cotton pulp, and rag pulp are also used for production. Therefore, paper bag paper has high mechanical strength and is generally used to make packaging bags for cement, pesticides, fertilizers, and other industrial products. To meet the requirements for filling, paper bag paper requires a certain degree of breathability and a large elongation rate.

　　牛皮紙包括箱板紙、水泥袋紙、高強(qiáng)度瓦楞紙、茶色紙板，牛皮紙是用針葉木硫酸鹽本色漿制成的質(zhì)地堅(jiān)韌、強(qiáng)度大紙面呈黃褐色的高強(qiáng)度包裝紙，從外觀上可分成單面光、雙面光、有條紋、無(wú)條紋等品種，質(zhì)量要求稍有不同。牛皮紙主要用于制作小型紙袋、文件袋和工業(yè)品、紡織品、日用百貨的內(nèi)包裝。牛皮紙分為U、A、B3個(gè)等級(jí)。

　　Kraft paper includes box board paper, cement bag paper, high-strength corrugated paper, and brown cardboard. Kraft paper is a high-strength packaging paper made of needle leaf wood sulfate paste with a tough texture and high strength, with a yellow brown paper surface. It can be divided into single-sided glossy, double-sided glossy, striped, and non striped varieties in appearance, with slightly different quality requirements. Kraft paper is mainly used to make small paper bags, document bags, and inner packaging for industrial products, textiles, and daily necessities. Kraft paper is divided into grades U, A, and B3.

　　牛皮紙的優(yōu)缺點(diǎn)優(yōu)點(diǎn)牛皮紙包裝由環(huán)保材料制成;強(qiáng)力的牛皮紙制成優(yōu)質(zhì)的牛皮紙盒;牛皮紙包裝是最具成本效益的包裝選擇;牛皮紙包裝在商業(yè)領(lǐng)域具有廣泛的用途;牛皮紙盒具有更好的圖形打印功能;牛皮紙箱易于個(gè)性化和定制。缺點(diǎn)主要缺點(diǎn)是牛皮紙不能遇水，稍加水就會(huì)軟化紙張，所以必須將袋子存放在干燥的地方。如果要存放液體產(chǎn)品，盡量不要使用牛皮紙。或者如果想用牛皮紙，可以選擇加一層防水PE膜。因?yàn)橹参锢w維素是牛皮紙的主要，加之牛皮紙工藝造就了牛皮紙另外的一個(gè)缺點(diǎn):牛皮紙往往比常見(jiàn)的紙要粗糙，如果您需要您的包裝產(chǎn)品光滑靚麗，那么牛皮紙是無(wú)法勝任的，牛皮紙宣揚(yáng)的是環(huán)保、健康、復(fù)古、溫情與質(zhì)樸。

　　What are the advantages and disadvantages of kraft paper Kraft paper packaging is made of environmentally friendly materials; High quality kraft paper boxes made from strong kraft paper; Kraft paper packaging is the most cost-effective packaging choice; Kraft paper packaging has a wide range of uses in the commercial field; Cowhide cardboard boxes have better graphic printing capabilities; Cowhide cardboard boxes are easy to personalize and customize. Disadvantages The main disadvantage is that kraft paper cannot come into contact with water. Adding a little water will soften the paper, so the bag must be stored in a dry place. If storing liquid products, try not to use kraft paper. Or if you want to use kraft paper, you can choose to add a layer of waterproof PE film. Because plant cellulose is the main component of kraft paper, and the kraft paper process has created another drawback of kraft paper: kraft paper is often rougher than common paper. If you need your packaging products to be smooth and beautiful, kraft paper is not capable. Kraft paper promotes environmental protection, health, retro style, warmth, and simplicity.
