63 results about "Color printing" patented technology

Color printing or colour printing is the reproduction of an image or text in color (as opposed to simpler black and white or monochrome printing). Any natural scene or color photograph can be optically and physiologically dissected into three primary colors, red, green and blue, roughly equal amounts of which give rise to the perception of white, and different proportions of which give rise to the visual sensations of all other colors. The additive combination of any two primary colors in roughly equal proportion gives rise to the perception of a secondary color. For example, red and green yields yellow, red and blue yields magenta (a purple hue), and green and blue yield cyan (a turquoise hue). Only yellow is counter-intuitive. Yellow, cyan and magenta are merely the "basic" secondary colors: unequal mixtures of the primaries give rise to perception of many other colors all of which may be considered "tertiary."

A method of flexographic printing of a tactile ink

A method for inline offset flexographic printing of tactile ink involves using an offset color printing unit to print a base color on the surface of a paper packaging box, followed by two or more flexographic printing steps to print the tactile ink onto the paper packaging box, resulting in a tactile ink thickness of ≥6μm on the packaging box surface. After finishing the paper packaging box using this method, the surface exhibits a matte gloss effect, and a subtle velvety feel can be detected by touch, enhancing the packaging box's aesthetics. Compared to single-pass printing of tactile ink, this invention uses a two-step flexographic printing process, improving the leveling effect of the tactile ink on the paper packaging box surface, increasing the ink thickness, and effectively reducing the accumulation of tactile ink during printing due to increased ink thickness and viscosity. Inline production results in less product deformation, smoother subsequent processes, and improved efficiency and product yield in later stages.

PendingCN122336758AAnti jammingColor printing
This invention discloses a product anti-counterfeiting and anti-tampering method and system that uses pre-stored codes and physical association with heat-shrinkable textures. By sealing and binding a unique code with the natural random texture created by the shrinking of the heat-shrink film, the anti-counterfeiting features are firmly attached to the product itself, making them impossible to remove or move. This fundamentally solves the problems of traditional anti-counterfeiting methods being easily counterfeited and reusable. The texture created by the heat shrinking of the heat-shrink film is a naturally formed physical deformation, unique to each product and impossible to replicate, resulting in exceptionally high anti-counterfeiting security. Combined with random color printing, diagonal mark image correction, and edge-sealing concealment features, a multi-layered, comprehensive anti-counterfeiting system with both overt and covert elements is formed. This system offers accurate identification, strong anti-interference capabilities, and outstanding anti-tampering effects. Moreover, the entire solution is simple to implement, low in cost, requires no dedicated identification equipment, is applicable to a wide range of products, is easy to use and promote, and has high practicality and market value.
