Description

Novel high-speed ink and water printing machine

Technical Field

The utility model belongs to the technical field of lithography apparatus, especially, relate to a novel high-speed ink and water printing machine.

Background

Ink-water printing is a special printing technology, and the ink that uses ink-water printing technique can show careful color change on the carrier, and the ink that ink-water printing used realizes need diluting and dissolving, does so in order to guarantee the level and smooth of color printing, because the ink after diluting carries out the light color printing and is more outstanding than the light color expressive force of ordinary special color, consequently the designer often utilizes the ink after diluting to carry out ink-water printing, forms the light bottom color on the paper and is used in order to be used in four-color printing afterwards. The operating principle of the ink printing machine is as follows: the characters and images to be printed are made into printing plate, then it is mounted on the printing machine, then the ink is coated on the position on which the characters and images are printed on the printing plate by manual or printing machine, then it is directly or indirectly transferred onto paper or other printing material (such as paper product, textile, metal plate, plastics, leather, wood plate, glass and ceramic) so as to reproduce the printed matter identical to printing plate.

At present, various industries are rapidly developed, and the demand for ink-jet printed products is continuously increased, so the speed of the ink-jet printer is continuously increased, the water-based ink used by the ink-jet printer contains a large amount of water and alcohols, the influence on the printing quality and the printing speed is great due to the limitation of the temperature of a workshop, the relative humidity is better at 60% -85%, the viscosity of the ink is most sensitive under the influence of different temperatures and humidity in winter and summer, the relative humidity is higher when the temperature in summer, the ink on the printed products is not easy to dry, and the humidity is relatively lower in winter, but the moisture at lower temperature is slowly evaporated, and the ink is also slowly dried.

The traditional improved drying method comprises the following steps: the drying agent is directly added into the printing ink, the aim of improving and stabilizing the machine speed is achieved by adjusting the pH value of the printing ink, a printed matter (non-printing surface) is directly contacted with a hot platform, namely a paper supporting plate before the printing ink is dried, even if steam or an iodine tungsten lamp tube is used for heating to evaporate water to improve the machine speed, the energy consumption is too large, an infrared or ultraviolet drying device is added in the other method, the investment is large, the machine speed is reduced due to the reasons, the printing quality is reduced, particularly, the dot printing is unclear, the color and luster of the part where the patterns or characters are concentrated are uneven, and therefore, the printing speed is influenced and the printing quality is also influenced.
