Digital DM9110 - Digital Design

The digital design of Heidelberg Digital DM9110, the open operating platform, the short-cut paper path and the structure of the design principles of the conjugate offset press make it very user-friendly in terms of print quality and operating efficiency. The uniqueness of Heidelberg Digital DM 9110 lies in:

* Excellent image quality

LED distortion-free write technology

The LED imaging technology exposes the surface of the imaged photoreceptor with physically parallel high-precision light-emitting diodes. The distance between each light-emitting diode unit and the surface of the photoreceptor is fixed, the same, and the same, and the exposure size at each point on the surface of the photoreceptor and The brightness is uniform and does not produce any distortion. In this way, high-quality images can be generated. At the same time, the LED write head has a small size, low power consumption, no attenuation, no rotating parts, and high output image quality can maintain long-term stability.

The inconsistency of the light emitting unit of the digital DM9110 write head is less than ±1%, and its controller can control the light emitting energy of each LED unit and strictly control the output light energy of each LED, thereby obtaining high-definition grayscale imaging quality.

GRET patent gray enhancement technology

GRET is an algorithm used to control the luminous energy of LED units. In addition to the "off" state, the LED write head can also produce 15 different exposure levels, and the resulting exposure point can be much smaller than the maximum exposure point.

The GRET algorithm will analyze the content of the image, as well as search for the edges of text and line art. When the algorithm determines the edge of a line, it will check the position where the staircase phenomenon may occur on this edge, such as on a slash or text line. Then, add smaller gray pixels to this line or text to produce smoother, more gentle edges.

GRET is implemented in high-speed digital hardware and integrated into the print control server software. All analysis and enhancements occur in real-time during the printing process without any manual intervention.

Digital write black technology

The old-fashioned digital press was developed from an analog copier. When imaging, all non-image areas on the page were exposed and then imaged. Because in the analog copying machine, the place where the original has the word is black and non-reflective, where there is no word is white reflective, it is easy to achieve background exposure and obtain the image of the unexposed part. The work of the “writing” background of the old-style digital printing press replaced the exposure lamp of the copying machine with a laser exposure source to complete the background exposure, and the remaining part is a useful image, which is called a digital writing white technology.

The disadvantage of the digital whitening technique is that the lines or dots are not generated by the exposure itself but by indirect removal of the unwanted areas, and the quality of the edges of the dots and lines will be greatly affected.

In contrast, the Digital DM9110 is a truly complete digital imaging system. The photoconductor and toner used are newly developed. Exposure uses LED technology. When imaging, it only exposes parts of text and images, the so-called black writing technique.

Finer imaging carrier

Another key aspect of the high print quality of the Digital DM9110 is the image carrier system, which uses approximately 35 microns in diameter, which is less than one-fourth the size of other particles used in similar products. The result of using such particles is like having a soft brush, making the print content smooth and detailed.

Another unique feature of this imaging carrier system is the use of a high-speed rotating magnetic core. The magnetic core is rotated at a high rotational speed, so that the toner in the soft magnetic brush formed by the carrier can be attached to the photosensitive body in a gentle and effective manner to generate a high-quality image.
