To unravel the mysteries surrounding digital printing, the IPA Digital Printing Forum (IPA Digital Printing Forum) conducted a series of studies and compared the output quality of eight digital presses with Heidelberg XL105 sheet-fed presses. Digital presses participating in this comparative experiment include Kodak's Nexpress S3000, Konica Minolta's bizhub PRO C6500, Punch Graphix's Xeikon 6000 and 8000, and Xerox's iGen3.
Hewlett-Packard did not directly participate in the experiment, but North American Color and Cobher Press, two users of the HP digital press, provided the IPA with printing proofs of the Indigo press.
This comprehensive survey covers all aspects of digital print production, including the color, the variability between printed sheets, and the physical characteristics of the print, such as: abrasion resistance, crack resistance, and fade resistance. In addition, IPA also evaluated the printing speed of digital presses and the ability to meet GRACoL (American Offset Commercial Printing Specification Organization) standards during the testing process.
The IPA Digital Printing Forum evaluated for the first time in North America the deinkability and recyclability of proofs produced by different printing presses. They established a digital deinking and recycling laboratory at the University of Western Michigan in the United States, and found that digital printing materials can be deinked, and their paper can also be recycled and used to make post-consumer waste products.
The study also yielded a very interesting result: high-priced digital printing equipment may not necessarily achieve higher print quality - although expensive printing units may have more data processing capabilities, faster speeds and More advanced post-press processing functions.
Image consistency and toner cracking
In the test of image consistency testing, a total of 1,000 printed sheets were printed and measured. The results showed that the ink density only showed a deviation of less than 0.1 in the digital printing process. In another test, people analyzed the darkest patches in the image and found Konica Minolta's printing equipment could print the darkest effect at an L* value of 6. In addition, the IPA staff entered the computer through the Pantone spot colors printed on the printing machine and found that both the digital printing press and the offset printing press matched the Pantone spot colors of 40% to 50%.
When folding an area where the ink coverage is high in a sheet, the performance of the digital sheet is almost no different from the offset proof. Digital prints are more resistant to problems such as ink film wear and tear that often occur during post-press processing, transportation, and manual handling.
With the acceleration of the industrialization process, the position of the mold industry in the manufacturing industry has become increasingly prominent. As an important branch of the manufacturing industry, the development of the mold industry directly affects the competitiveness of the manufacturing industry. However, the mold industry in the rapid development of the same time also faces some challenges. This paper will discuss the development status and market demand of auxiliary equipment in the mold industry, as well as future development trends and challenges.
First, the development background of the mold industry
Mold industry is an important part of the manufacturing industry, mainly involved in the design, manufacturing, sales and service of molds, fixtures, fixtures, etc. With the continuous development of the manufacturing industry, the demand for the mold industry is also growing. However, the current mold industry is facing some problems, such as slow technological update, low production efficiency, and increased cost pressure. Therefore, the mold industry needs to constantly introduce new technologies, new equipment, improve production efficiency and reduce costs to adapt to market changes.

2. Makino: CNC machine tools are the main products, high precision, high efficiency, and have a perfect after-sales service system.
3. Haas: CNC machine tools are the main products, the product line is relatively narrow, but it has the characteristics of high precision, high efficiency and high quality.
Future development trends and challenges
1. Development trend
In the future, the development of auxiliary equipment in the mold industry will develop in the following directions:
(1) Intelligence: With the continuous development of artificial intelligence technology, intelligence will become an important development direction of auxiliary equipment in the mold industry. Intelligent equipment can improve production efficiency and quality through data analysis and optimization algorithms, while reducing manual intervention and operational difficulty.
(2) Green environmental protection: With the continuous improvement of environmental protection awareness, green environmental protection will become an important development direction of auxiliary equipment in the mold industry. Green equipment can reduce energy consumption and environmental pollution, while improving production efficiency and product quality.
(3) Personalized customization: With the continuous development and upgrading of the manufacturing industry, personalized customization will become an important development direction of auxiliary equipment in the mold industry. Personalized customization can meet the needs of different customers and improve the competitiveness and added value of products.
Step 2 Challenge
In the future, the development of auxiliary equipment in the mold industry will face the following challenges:
(1) Technological innovation: With the continuous upgrading and change of the manufacturing industry, technological innovation will become an important challenge for auxiliary equipment in the mold industry. Enterprises need to constantly introduce new technologies, new processes and new materials to improve the competitiveness and added value of products.
(2) Brand building: Brand is an important guarantee for the development of enterprises, but the main mold industry auxiliary equipment brands on the market have been relatively stable. Therefore, enterprises need to continuously improve brand awareness and influence to expand market share and increase the added value of products.
The gap in quality between digital presses and offset presses is shrinking
Digital printing is often not recognized by everyone because of color management, print quality, and durability. Some people think that digital prints often shift during the production process, they are unable to carry out color management, they cannot be matched with Pantone spot colors, and the areas with thicker ink film are broken during folding. According to the latest technical report of the International Prepress Association (IPA), these criticisms of digital printing are actually misunderstandings. In many cases, digital printing can be comparable to offset printing, even in terms of color, print quality, and durability. Performance exceeds offset printing.
