Background

With the development of advertisement media technology, the technologies of impregnation, coating, temporary writing and the like by adopting PVC cloth are difficult to meet the requirements. Digital printing technology has achieved great success on conventional cloth, but there are still difficulties in the application of advertising cloth.

On the one hand, advertisement cloth generally has the crossing line of longitude and latitude, and there is less pore structure in the material surface, when light shines from advertisement cloth back, front respectively, can appear two kinds of visual effects, and whether the lamp is lighted in the advertisement case promptly, visual effect is inconsistent, can cause consumer's confusion misunderstanding.

On the other hand, the dyes can be fully combined on the advertising cloth by adopting the modes of dipping, coating and the like, but the digital direct injection technology is easy to generate the phenomenon of white exposure which is not obvious under natural light, but when the lamp is turned on in the advertising box, partial light rays are emitted from small holes to amplify the phenomenon of uneven dyeing of the fibers of the advertising cloth, and the white exposure is easy under the light.

Patent application CN106336734A discloses a digital color inkjet ink with 3D lines suitable for vamp printing, which is prepared from the following ingredients by weight: 2 to 25 percent of oligomer of polymer or copolymer containing carboxylic acid group (COOH), 35 to 65 percent of monomer, 2 to 10 percent of pigment, 2 to 10 percent of photosensitive initiator, 2 to 35 percent of solvent and 5 to 15 percent of additive containing pigment dispersant or physical property regulator. The scheme ensures that the pigment color ink-jet ink can be rapidly cured by absorbing ultraviolet light, has good adhesive force, and replaces the organic solvent to be dissolved and permeated into the base material to be attached by a photocuring attachment mode so as to reduce the utilization rate of the organic solvent, thereby reducing the harm of the organic solvent to the environment and human body, and the three-dimensional pattern color has the advantages of being foldable, twistable and non-deformable.

Ink detection

The detection method comprises the following steps: lab value test and comparison of color colors are carried out by professional color measurement software of Alice, and a Lab color model consists of three elements of brightness (L) and related colors, namely a and b. L represents lightness (luminescence), a represents a range from magenta to green, and b represents a range from yellow to blue. The value range of L is from 0 to 100, and when L is 50, the color is equivalent to 50% of black; the value range of a and b is from +127 to-128, wherein +127a is red, and gradually transits to-128 a to become green; in the same principle, +127b is yellow and-128 b is blue. All colors are composed by alternating changes of these three values. For example, a color block has a Lab value of L100, a 30, and b 0, and is pink.

Difference contrast between two identical colors color differences can be judged from the Lab value and the Δ E difference, where

Wherein the delta E is more than or equal to 0.5, the two comparison samples have obvious color difference, and can be obviously judged by naked eyes, wherein the color to be tested is that the ink is printed and directly sprayed on the lamp box cloth, and then the color development is carried out for contrast analysis after the ink is printed for 10s at 220 ℃.
