DNP's Basic Technologies
Since its founding, DNP has developed a wide range of technologies through its ongoing development and provision of products and services that meet the needs of society. By adding the latest technologies to DNP's unique technologies born from the printing process, and by enhancing and combining each of these, DNP is developing its core technologies.
Information Technology
plan
The technology to think about "what to make and why" and promote projects through dialogue
Book printing process example
Plan
Depending on the content and target audience, we calculate the number of colors, the printing format, the type and thickness of paper, the printing method and production line to be used, the schedule and costs until delivery, etc. We propose the most efficient and effective method and prepare the manuscript and materials to be submitted.
The technology used in this printing process
Publishing Solutions
We can select the most suitable content from all media, including paper, electronic, and online, and propose effective methods of expression, such as still images, videos, CG, and AR/VR.
Branding Design
By researching companies and products, we identify strengths and weaknesses in management and propose the ideal form to aim for.
sales promotion
We can provide total design and execution, from marketing research to planning, production, delivery and effectiveness measurement of various promotional tools.
design
"How do we make it?" Technology that creates robust and precise designs to realize the goal
Book printing process example
Design
This process, called bookbinding design, is divided into two parts: the main text and the cover, and concretely embodies the image of the book that was considered in the planning stage, such as the size of the book, the type of cover, the font style of the main text, and the number of pages.
The technology used in this printing process
Package design
Aiming to be "kind to people, kind to products, and kind to the earth," the company is engaged in research and development, product planning and design, and application development related to packaging.
Living space design
With a track record of manufacturing interior and exterior materials for homes, offices, medical facilities, automobiles, and trains, we have expanded into a variety of products and services for creating comfortable spaces.
optical design
This technology precisely controls the direction and color of light to bring out the functionality of the product. It also controls the surface shape and layer structure of the product on the order of micrometers and nanometers, taking into account errors in the manufacturing process.
Information Processing
Technology that safely collects, organizes, analyzes, and processes all kinds of information to create new added value and ways of using it
Book printing process example
Process information
This involves organizing text and photo manuscripts, as well as design, layout, and editing. Image processing, such as adjusting the colors of the photos and designs to be used and removing unnecessary parts, is also done at this stage. This is also called the pre-processing, as it involves preparatory work before printing, such as separating the manuscript into four colors: cyan, magenta, yellow, and black.
Printing technology
Microfabrication
A technology that applies high-precision, detailed processing to base materials such as metal, glass, and resin to impart the effects and functions necessary to achieve a desired goal.
Book printing process example
Making plates and printing plates
With the advancement of digitalization, direct output printing of manuscripts has become a method, but when printing large quantities, printing plates must be created to be set on the printing press. These plates differ depending on the printing method. It has also become common to create printing plates by outputting directly from a workstation. Generally, in order to create printing plates, a film-like manuscript is first created, and this is called plate making.
Gravure plate making by corrosion
Precision coating
A technology that forms a single or multi-layer coating of various materials uniformly and evenly on the surface of substrates such as paper, resin, metal, and glass.
Book printing process example
Ink is applied to the printing plate and spread thinly and evenly onto paper or film. Printing methods include letterpress printing, lithographic printing (offset printing), intaglio printing (gravure printing), as well as stencil printing (silk printing) and digital printing (direct output), and each method requires a different printing plate.
Main printing methods
Toppan Printing
Ink is applied to the raised areas of the plate and printed directly. This method is mainly used for books and comic magazines.
offset printing
Taking advantage of the repulsive properties of water and oil, oil-based ink is first transferred to a rubber blanket and then indirectly printed. It is mainly used for color printing of magazines, posters, etc.
Gravure printing
Ink is applied to the recessed areas of the plate, and a blade is used to scrape off the ink from areas other than the text or image you want to print. Pressure is applied to print the ink remaining in the recessed areas directly onto paper or other materials. This method is primarily suitable for printing photographs, as it produces fine details such as shading.
Post-processing
Technology that achieves the necessary safety, durability, and convenience according to the product's usage environment and purpose
Book printing process example
Binding and processing
Large sheets with multiple printed pages are folded in page order, stacked, and bound. The excess is then trimmed off to create the desired shape. In the case of hardcover books with elaborate covers, the pages may be folded after the main text has been trimmed. The sheets are then processed into a functional shape to suit their intended use.
Printed sheets are stacked and bound together to form a book
Folding and collating
Fold the printed paper and arrange it in page order.
Binding
The collated books are bound together and a cover is attached.
Cutting
Three sides are precisely cut to fit the finished dimensions.
Material development, evaluation and analysis
Materials Development
A technology for synthesizing, dispersing, and mixing new materials, and for designing and manufacturing inks, adhesives, photosensitive materials, coating materials, etc.
The technology used in this printing process
Color materials/photosensitive materials
Materials for expressing color and for fixing images and shadows created by light. They are processed with high precision so that they can be used in photolithography, which requires precision on the micron level.
polymer material
Polymer materials, such as plastics and fibers, are among the materials that play an important role in our daily lives, along with inorganic materials such as metals and ceramics.
organic synthesis technology
This technology synthesizes organic materials to make them suitable for various products. We manufacture functional coating materials, resist agents for cutting-edge photomasks, and active pharmaceutical ingredients for pharmaceuticals.
Dispersion/compounding technology
This is an important technology that influences the performance of materials. We design the composition of raw materials to ensure that the material's functions perform at their best, and ensure consistent quality by dispersing the materials evenly and uniformly.
Evaluation and analysis
This technology is essential for product assurance of electronic components, which require nano-level precision, and for defect repair to increase yields.
The technology used in this printing process
analysis design
We design the evaluation method, analytical equipment, processing system assembly, etc. The key is to get results as quickly and accurately as possible.
analysis technology
This is a technology that utilizes advanced, cutting-edge analytical equipment to analyze the structure of ingredients, etc. DNP has established a large-scale evaluation and analysis center to handle this.
Simulation Technology
This technology creates a database and analyzes the behavior of materials and airflow on production lines according to the purpose, and predicts the results of line operation, as well as the performance and quality of products and materials. This allows for the optimization of high-quality material designs and efficient, stable production line designs.
Database analysis technology
By comparing data analyzed using various analytical equipment with our own analytical database, we can identify product defects and other issues with high accuracy in a short amount of time.
