Description

Technical Field

[0001] The present invention relates to the field of printing, and in particular to a printing device and a printing method. Background Art

[0002] At present, the fast-moving consumer beverage packaging industry is dominated by plastic cups. With the gradual development of the market and the changes in demand, many new cup types are constantly emerging. In the process of changing external demand, the shortcomings and defects of cup printing equipment in the current market have emerged.

[0003] At present, some products on the market have unclear patterns when printed directly due to material problems. In order to make the pattern more eye-catching, the existing method is to first print the base color on the product and then cover the pattern on the base color. However, given the characteristics of the printing process, direct covering will cause the white base ink to mix with other color inks and be transferred to the rubber blanket. The inks will mix and affect the printing effect. To complete this function, the existing equipment will first print a single color ink and solidify it to ensure that the inks will not mix. In order to add the process of printing the base color, at least two steps need to be added to the printing equipment, and then the mold station needs to be added to adapt to the new printing mode, resulting in the need to redesign the equipment and increase the equipment cost.

The words "first", "second" and similar words used in the present invention do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one" or "one" do not indicate quantity restrictions, but indicate the existence of at least one. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships.
