The preparation step ( S10 ) is a step of preparing a base film 110 having a first surface 112 on which an rugged refraction pattern is formed to obstruct the path of light. The base film 110 is formed of, for example, a transparent film, and may be composed of a film formed such that light transmittance varies depending on an angle.

The base film 110 is configured such that the path of light changes depending on the angle by the refraction pattern. That is, a refraction pattern is formed on the first surface 112 of the base film 110 to obstruct the path of light. The refraction pattern is configured such that light incident from the front is transmitted and light incident from the side is not transmitted by alternately repeating a portion that transmits light and a portion that does not transmit light. In addition, the refraction pattern may be formed and manufactured in various known shapes for limiting the viewing angle.

Mixed ink application step (S20)

The mixed ink application step (S20) is a step of applying a mixed ink in which UV ink and nano ink are mixed to the first surface 112 of the base film 110. That is, since the UV ink used in the present invention is generally transparent, the mixed ink having the first color is formed by mixing the nano-ink having the first color.

The composition of the UV ink is not particularly limited as long as it can be cured using a UV curing lamp. Nano ink is easily mixed with UV ink because the particles are small at the nano level. That is, in the present invention, since other inks other than the nano ink are not easily mixed with the UV ink, it is preferable to mix the nano ink having the first color with the UV ink.

Then, the mixed ink of UV ink and nano ink is applied to the first surface 112 of the base film 110 . In this case, the mixed ink may be applied along the first direction to the first surface 112 .

Squeeze seating step (S30)

The squeeze seating step (S30) is a step of seating the squeeze (S) on one side of the upper surface of the mixed ink applied to the first surface (112). The squeeze (S) may be formed, for example, in the form of a rubber rod formed in a long shape along the longitudinal direction and having a rectangular cross section.

Forming a first color implementation layer (S40)

In the first color implementation layer forming step (S40), the squeeze (S) is moved left and right so that the upper surface of the mixed ink is formed flat on the first surface 112 to form a flat first layer on the upper surface of the first surface 112. This step is to form the color implementation layer 120 .

The squeeze (S) is connected to a known horizontal moving means (not shown), etc., and is repeatedly moved several times toward the other side of the upper surface of the mixed ink in a state in which the lower side of the squeeze (S) is in contact with one side of the upper surface of the mixed ink.

Then, the lower side of the squeeze (S), whose cross section is formed to be square and flat, is repeatedly moved in a direction perpendicular to the longitudinal direction of the squeeze (S) in a state of being in surface contact with the upper surface of the mixed ink, The pressure is evenly transmitted to the mixed ink. Accordingly, the refraction pattern formed on the first surface 112 of the base film 110 is evenly filled with the mixed ink, and the upper surface of the mixed ink, that is, the upper surface of the first color implementation layer 120 is flat rather than uneven. formed to be

That is, there has been an attempt to manufacture the multi-color panel 100 using the base film 110 in the prior art, but when the mixed ink is applied to the top of the refraction pattern provided on the base film 110 and then cured as it is, the mixed Since the rugged surface is formed on the upper surface of the ink by the refraction pattern, there is a problem in that the color is slightly different depending on the rugged shape rather than the viewing angle.

The present invention is to solve the problems of the prior art, and the mixed ink fills the gap between the refractive patterns provided on the base film 110 using a squeeze (S), and the squeeze (S) is By moving left and right on the surface, the upper surface of the mixed ink, that is, the upper surface of the first color implementation layer 120 was implemented to be flat rather than uneven.

As such, since the upper surface of the first color implementation layer 120 can be flattened using the squeeze (S) of the present invention, the first color applied to the first color implementation layer 120 becomes thicker depending on the user's viewing angle. Or, there is an effect that can be changed to make it look lighter.

Forming a second color implementation layer (S60)

The second color implementation layer forming step ( S60 ) is a step of forming the second color implementation layer 130 by coating a fluorescent ink having a second color on the upper surface of the cured first color implementation layer 120 . At this time, the fluorescent ink is configured to have a different color from the mixed ink. Further, the fluorescent ink is applied on the upper surface of the first color implementation layer 120 along a second direction that is the same as or different from the first direction to form the second color implementation layer 130 . The second color implementation layer 130 may be configured to be cured through a known curing process.

When the second color implementation layer 130 is formed in this way, the second color applied to the second color implementation layer 130 can be implemented to appear darker or lighter depending on the user's viewing angle.
