Charm
The position of centennial offset printing in today's printing market is unstoppable by several other printing methods. In every place where we live and work, we have branded the traces and shadows of offset printing, packaging cartons, labels, stationery, clothing tags, etc., simply to mention. It is the charm of offset printing that makes this world more beautiful.
The vividness of the image reproduction and the delicate color tone are the charm of offset printing. Compared to gravure, offset has previously been able to reproduce a small color gamut, but with a color management system, the color of offset products has improved a lot. In addition, FM screening technology can make image layer and color reproduction more abundant.
Offset printing uses color management technology, which is more convenient than gravure printing. After printing, 90% of the products met the customer's requirements.
The charm of offset printing is the color management technology and modern plate-making technology, making offset printing in the printing market.
A few years ago, when hybrid ink offset printing technology was unveiled, it was once regarded as a flash in the pan. Nowadays, the development of UV offset printing technology, hybrid ink offset printing technology and online UV high-speed glazing have been increasingly marketed. More praise, because it achieves the offset high-speed UV glazing of the offset press, it can leave a silky luster on the print, resulting in a new texture.
Now, UV offset printing technology has shown unprecedented prosperity in the global printing market. In China, UV offset printing was mainly used in high-end packaging such as cigarette packets and wine bags. With the advancement of UV offset technology, UV offset printing is quietly infiltrating into other printing markets, and savvy printers have targeted some special markets.
In China's printing circle, using the delicate color reproduction capability and UV offset printing technology, we are fully exploiting the commercial printing and packaging printing market. 3D printing, in-mold label printing, synthetic paper printing, and plastic sheet printing are all high-value products with high added value. Among them, plastic folder printing is a typical product. The plastic folders used in the past are all products without any printing color. Now using UV offset technology and UV glazing technology, the company's logo and slogan are printed on the plastic folder, which gives the once-inconspicuous plastic folder. Brilliant colors and new values. It is the charm of UV offset printing that allows colorful and unique ways to help colorfully develop differentiated and value-added products.
Vitality
Although offset printing has gone through a century of development and entered a mature development period, innovation has always been a source of vibrant printing and has become a driving force for the continued development of offset printing. The four-year-old drupa has become the showcase for offset innovation technology, and many offset innovations are starting from here and going global.
First of all, from the printing color, there are more and more offset color groups, and the configuration is getting higher and higher. It is not surprising that an offset press plus a light unit can reach 11 units. For example, KBA’s longest offset printing Machine, configured to reach 14 units for high-quality double-sided printing plus light.
In packaging and printing, the light on the line has become increasingly popular and has become a fashion for packaging printing. The high configuration of the equipment gives the packaging offset a flexible and value-added element, which makes a significant breakthrough in printing results. For example, partial glazing, reverse glazing, gold (silver) glazing, pearl glazing, aqueous glazing, protective glazing, and wiping, bubbling or scented glazing can be achieved.
Secondly, the printing format tends to be large format, satisfying the demand for large-format printing of commercial prints, large format posters, POP display stands and micro corrugated cartons. For example, the KBA Rapida 205 offset press has a maximum printing area of 1510mm × 2050mm, which meets the printing needs of ultra-large packaging.
The rise of offset printing technology has made the offset vibrant.
The line cutting device is a highlight of the offset press. The Heidelberg XL105 and the Manroland Roland 700 sheetfed offset press can be equipped with a line cutting device, so that the sheetfed offset press can also use the web, and the cost of raw materials is reduced. 20%. The connection cutting technology is also found in KBA's large-format sheetfed offset presses Rapida 205 and Rapida 185. They are equipped with a cutting device on the stamping cylinder of the last unit to connect the printed matter. Line cutting.
The hot stamping is to add a cold stamping device after the offset printing unit. The hot stamping foil is wound on the blanket cylinder. The pressure of the blanket cylinder and the impression cylinder is used to bond the image coated with the adhesive to the hot stamping foil. The stamping unit can also be used as a regular unit. This technology has been used on the Roland 700 in Manroland and is best suited for packaging printing.
The die-cutting version of the final machine assembly of the offset press allows for post-press finishing. There are also many machines equipped with online drilling holes, online numbering devices, and even corona processing units to facilitate the printing of plastic, film, concave-convex film and other materials with low adhesion.
Wiring detection is to install a camera on the last color group of the press to perform video detection on the printed product. It can detect the quality of each sheet while the offset printing machine is running at high speed, and can also detect the size of the sheet; it can also detect the printing density, overprinting and so on. This connection detection device reduces the printing reject rate.
Digital technology sneaked into printing technology, making the dream of offset printing machines a reality. With the help of JDF, offset printing technology has entered a new era.
Pressure
The market environment we are in today is changing the printing industry and opening up new markets for sheetfed offset printing.
Pressures 1: urgent delivery
Global communications are becoming faster and faster, communication facilities are ubiquitous, making business tempo faster, delivery pressures and printing services need to be completed in a short period of time, thus placing higher demands on offset printing preparation.
Globalization has enabled more customers to reach out to printers around the world, thus increasing the opportunity for customers to select printers and increasing pressure on printing companies because they need to deliver at scheduled times.
Pressure 2: the printing price is fiercely competitive
The competition for offset printing prices is fierce because rotary offset printing has been able to print high quality products. At the same time, the investment threshold of offset printing is no longer high, and low-price competition has become a means of survival for some printing houses. To a certain extent, printing companies have entered the strange circle of low-price competition.
Pressure 3: profit margin is compressed
The price of paper materials continued to rise, which to some extent swallowed the profits of offset printing. Global oil prices continue to hit new highs, and the rise in the price of ink raw materials has become inevitable, eventually leading to the continued rise in ink costs. The profit margin of offset printing was further squeezed under the influence of macroeconomics.
Pressure 4: Customers' demanding quality requirements
The pursuit of print color by printing customers is endless, and some print customers have to maintain the durability of the finished surface of the prints for decades, and this trend will continue to strengthen in the next few years.
Pressure 5: short version
We live in an era of individuality and diversity, and short-run printing is the product of this era. With a considerable number of offset jobs, the volume of prints tends to decrease, and digital printing of short-run offset printing jobs is not surprising and will continue.
Pressure 6: pressure from flexographic and gravure printing
In the label printing market, narrow flexographic printing is eroding a portion of the label offset business; gravure printing is still the strongest competitor in offset printing in the long-run packaging market. In the two-sided pinch of flexographic printing and gravure printing, the pressure on the offset printing cannot be ignored.
Pressure 7: pressure from the ecological environment
The call for environmental protection is growing, and VOC emissions from offset printing are being limited. Heavy metals in offset inks are somewhat out of tune with green printing. In the future, destined green offset printing will become the main theme of development.
Taken together, the above factors constitute the pressure of sheetfed offset printing. In the next 10 years, these pressures will profoundly change the profile of offset printing, and to some extent, the development direction of offset printing.
Due to technological advances, the highly competitive market needs to differentiate printed products, so Value-Added Print will become the future development trend of offset printing.
From the perspective of printing, there are many countermeasures for value-added. First of all, the delivery is fast; secondly, for the characteristics of the print, choose the most suitable process.
Innovative technologies are constantly being introduced, giving printers a wider choice. Surface finishing techniques that improve graphic printing and print durability, as well as printing on a wider range of material surfaces, are also important additions. Printing companies need to add value, in other words, differentiate.
Value-added printing requires more than just one machine, but also machine configuration and process innovation for a particular printing market.
In order to be in an invincible position in the future market competition, printing companies are thinking about a problem, how to provide high value-added prints for printing customers. Specifically, it is the printing company that needs to know the capabilities of the equipment and employees. At the same time, it is necessary to understand the current and future needs of the customers, to know each other and to know each other.
