In recent years, with the rapid development of digital printing technology and the diversification of business needs in the information age, digital printing has gradually emerged in the printing industry. Large-format printers as output devices for digital printing technology have broken the bottleneck of digital printing development. Mainly used in a variety of high-quality graphics and text output areas such as graphic printing, advertising, engineering drawings, GIS maps.
The fastest large-format color printer HPPageWideXL8000 in history, such as the following picture. Because of its unique performance advantages, HPPageWideXL8000 can adapt to expedited and fast printing tasks and can deliver mixed output in half the time. In order to ensure the long-term printing supplies and graphic output quality, HPPageWideXL8000 is equipped with 6 paper rolls and 2 large-capacity ink cartridges, which greatly reduces the time consumption caused by switching back and forth between media during the operation, and also guarantees color The drawing output is clearer and fuller.
With its amazing printing speed, intelligent processing software, and high-quality pigment inks, HPPageWideXL8000 can help users save 50% of the total cost. HPPageWideXL large format printing products entered the Chinese market in the two years after the total output of drawings for Chinese users reached 100 million square meters, HPPageWideXL8000 large format printer has promoted the process of Chinese drawings output from black and white and blueprint documents to color documents.
Compared to printers with printheads mounted on a scanning rack, the performance challenges of pigment inks used in large format printers are more severe. Prolonged opening has become a factor driving innovation in large format printing systems and their ink designs.
Then the question comes
We need to design inks that can be opened for a long time.
Strictly controlling the physical properties of the ink within the specification range is critical to the reliability of ink droplet ejection. When the print head is unsealed, moisture evaporates from the nozzles. All inkjet printing systems that use water-based inks cover the print head when not in use to prevent excessive water loss from the nozzles.
The nozzle of the inkjet print head is very small, only about one-fifth of the diameter of a human hair, so evaporation of water will cause the ink in the nozzle to condense in one or two seconds.
