Art Paper and Printing (V)

Art Paper Postpress

Usually after the printing is completed, the art paper will be processed in order to increase the gorgeousness of the art paper and highlight the distinctive taste of the product. Common post-press processing and precautions are as follows.

1. Pressure bump

Because most art papers have good bulk and toughness, embossing is often used in post-press processing of art papers. Different art papers with different textures weigh different pressures and should not be the same. Art paper with heavy grammage and loose paper has a relatively large pressure at the time of embossing, which can ensure the conspicuousness of concavity and convexity.

2. Hot stamping

Hot stamping is often used in small areas, such as logos and product names. In the hot stamping process, the temperature and pressure of hot stamping must be strictly controlled, otherwise hot stamping is not easy.

Tipping paper processing

The tipping paper is a reel type material, and most of them adopt a round press hot stamping method, which has an overall hot stamping and a single hot stamping. Hot stamping equipment is mainly made in domestic equipment, such as Zhejiang Haining Tengda, Ruian powerful, Xi'an black cattle equipment, but also imported equipment, typical of France Shangbang. The heating method uses electricity or oil heating. The hot stamping plate cylinder is an integral plate, which cannot be used as a local plate like cigarette packs. The base material is copper and steel (the thermal conductivity of copper is good, and the resistance of steel is high).

Due to the low quantification of tipping paper products, it is generally around 40g/m2. Therefore, the temperature and humidity of the workshop are required to be higher. It is better to maintain the constant temperature and humidity, and the hardness and material of the impression cylinder are also high. Claim. In the corrugated paper hot stamping process, the factors that affect the product quality mainly include the following aspects.

1. Effect of anodized aluminum

In the hot stamping process of corrugated paper products, the quality of anodized aluminum is closely related to the quality of hot stamping. If the tightness of the anodized aluminum is improper (too loose and too tight) will cause the hot stamping is not true; Improper temperature of the hot melt adhesive will cause a hot stamp paste; production time of the anodized aluminum is too long or too short, the tension is too large or Too small, inaccurate hue, or instability can directly affect product quality. Taizhou, Zhejiang, Wenzhou Yushi, Guangdong Sihui Sun and other companies produced the corrugated paper hot stamping aluminum quality is relatively stable. To some extent, grasping the quality of anodized aluminum is equivalent to controlling half of the product quality.

2. Influence of the hot materials

The impact of the hot-ironed materials on the hot stamping quality of the water pine paper products is mainly reflected in the ink layer on the surface of the hot-lining material. If the white ink used as the diluting agent in the ink is added in excess, the electric aluminum will be pulled back, causing the hot stamping to be false. In addition, the temperature resistance and thickness of the ink layer will also affect the quality of the stamping product, especially when printing with pearlescent ink.

3. Effect of hot stamping speed

The hot stamping speed is too slow, and the hot stamping pattern is not clear (except for products with special requirements). With the increase of speed, the performance of the aluminum foil and the hot stamping temperature, the hot stamping pressure reach the best state, and the pattern and text on the product The lines become clear. The vast majority of tassel paper hot stamping speeds are appropriate at about 40 m/min, and should be adjusted depending on the complexity of the pattern, the size of the text, and the thickness of the lines.

4. Effect of hot stamping temperature

The level of hot stamping temperature plays a key role in product quality. Hot stamping temperature is too high, which can easily cause pattern blooming. If the temperature is too low, hot stamping is not easy. The use of oil or electric heating method, the choice of copper or steel as the substrate of the hot stamping plate in the temperature control is also very different, usually equipped with a temperature detector, is mainly used to detect the actual temperature of the hot plate surface.

5. Influence of hot stamping pressure

Hot stamping pressure mainly refers to the pressure of the rubber pressure roller on the hot stamping plate. It also plays a very important role in the hot stamping of tipping paper. If the pressure is too small, the hot stamping will not be caused, and the paste will be generated after the convention, and the service life of the tipping and hot stamping version of the tipping paper product may be shortened. When setting the pressure, it should be gradually increased from small to large.

With the development of hot stamping technology, it is believed that the cold stamping and hot stamping techniques used on cigarette packs will also be applied to tipping paper. For the corrugated paper hot stamping production enterprises, they should keep pace with the pace of development and reposition themselves so as to remain invincible in the future competition.

Drinking water Siyuan art paper where to go

At the beginning of the reform and opening up, a large number of foreign art pattern paper products influxed into the Chinese market, which produced a sharp contrast with the domestic art pattern paper. At that time, domestic art paper still used the traditional hand-made mode, which resulted in high product costs and low output. The vast majority of art paper use was limited to the art community, while foreign art paper production plants were mostly large enterprises with advanced technology and equipment and well-funded enterprises. The art paper produced has high color saturation and complete specifications, and is suitable for printing in large quantities on the machine. At that time, the domestic printing industry was limited in technology and equipment. Therefore, although the quality of foreign art paper was excellent, the domestic market lacked the recognition of expensive imported art paper. Only a small number of enterprises in the southern coastal cities used the imported art paper. The proportion of the entire domestic paper market is minimal.

Nowadays, there are a large variety of artistic pattern papers on the market. From the point of view of raw materials, in addition to retaining traditional natural fibers, a large number of artificial chemical materials, metal materials, and mineral materials are also used, and the process is constantly innovating. With the increasing use and expansion of paper in the field, the ancient art pattern paper has created a brand-new market space for the relevant manufacturers and distributors. In the future, art paper will go from here to the next.

Art Paper Market Problems

One day, the company's employees laughed and said: Today, a customer has bought a bad color to buy paper, the amount is not small yet. What does it mean to be a bad color? Originally, although the samples in the customer's hands are in one-to-one correspondence with the manufacturers and models, the colors are far from each other. This manufacturer is either eager to survive or develop, and if the products are not finalized, they are eager to push them to the market, and they will improve while selling. The customer really selected, the end of the paper is different, the production process is also different, the customer is helpless, the manufacturer is helpless, the dealer is more helpless.

What are the reasons for the current art paper products so quickly update it? Calmly analyzing, we found that there are mainly two reasons.

1. Manufacturers lack confidence in their products
Some manufacturers, when they see other related products come out, are afraid of themselves and are eager to introduce newer varieties. The old products have not brought sufficient returns to the enterprise. The new round of development of art paper has been on the market. Similarities and differences, or the appearance of a god, or out of context, similar products, no characteristics, and ultimately will inevitably move toward a vicious circle of price wars.

2. Lack of communication between manufacturers and agents
Many manufacturers do not have good products, but they can't sell them, so they simply do their own marketing. On the contrary, many good sales companies are forced to invest in factories by themselves because they do not have good suppliers for a long time. With such development and sales, each has its own battle, lack of communication and consensus, and each company has brought great losses in human, material and financial resources.

Rely on the advantage of brand building logistics platform
With the large-scale application of packaging paper in industries such as food, medicine, health care products, cosmetics, tobacco and alcohol products, etc., the paper's production process, technology and equipment have been widely promoted in the country. Many companies have hoped for gold and silver paper and cardboard products, reappearing scenes of art and craftsmanship on the art papers. However, the beautiful scenes have already passed. Special paper baskets such as colored adhesive tape, textured paper, and lightweight paper were gradually added to the ranks of thermal paper and became popular printing paper. Joining foresighted, powerful, and distinctive fine art pattern paper companies, are not willing to make profits for the moment, honesty and commitment, diligent efforts, and jointly build a harmonious and stable supply and marketing logistics platform, is the inevitable trend of the future development of art paper enterprises.

The 21st century is the era of the Internet. Running an enterprise requires a sense of common sense, and the market is intangible but sentimental. Enterprises are people and people are businesses.
