KR20000018154A - Offset-printing additional over glow in the dark - Google Patents

Abstract

PURPOSE: An offset printing method is provided to use for products such as an exit mark, a fire extinguisher, a fire alarm, a safety mark, a night advertisement board, and a sticker for a vehicle by making the shape and colors of the product to be easily seen at night place. CONSTITUTION: An offset printing is completed by printing cut-off white screen on a hologram raw material, printing screen by compounding fluorescent pigment and soft transparent ink, plating with gold foil to make neat the rim line, and treating with epoxy to give cubic effect to each sticker. The fluorescent pigment is better than ZnS group so that the remaining time of the visible light remaining time in the dark place of the fluorescent pigment is over 20 hours. Thereby, the original function of the fluorescent pigment is displayed when for safety marks or advertisement objects.

Description

OFFSET-PRINTING ADDITIONAL OVER GLOW IN THE DARK}

The present invention combines offset printing on Fluorescent Pigment (long luminous) for the first time and can be seen at the same time as the color and shape of the picture at night (even in the dark).

In general, the type of luminous sticker on the market is printed by screen printing (silk printing), which does not express tens of millions of visible colors.

Take red roses as an example, the red roses we see are not just red, but are dark and bright in shades of color. have. However, screen printing cannot express more than one color, so no texture or volume can be expressed in screen printing. In addition, the red rose can only express the form of a simple red rose. In addition, the conventional photoluminescent sticker does not function as a position display in a dark place because the light is very weak due to the use of a single photoluminescent pigment. Offset printing is combined on the fluorescent pigment to express the shape and color of the picture clearly even in the dark.

What is Fluorescent Pigment?

First, it does not contain radioactive material.

Conventional ZNS-based photoluminescent pigments are mixed with radioactive materials such as PN to compensate for the weakening of the light, but there are many restrictions on their use due to the emission of radioactive materials.

However, Fluorescent Pigment is made of inorganic materials that are harmless to the human body as a main raw material and is manufactured by a new method without adding radioactive substances.

Secondly, Fluorescent Pigment is superior to ZNS system, so the recognizable afterglow time in the dark room is 20 hours or more, so it is used for safety signs or advertisements and shows the original function of photoluminescence.

Third, the stability is excellent. As it is a chemically extremely stable crystal formed at high temperature, it has excellent heat resistance and cold resistance, so it maintains photoluminescence at high temperature (1500C) and low temperature (-20C), and has excellent chemical resistance. There is no change in physical properties even below.

Offset printing is a printing method that allows us to express all the colors of all tens of thousands of colors all the same. Offset printing consists of four colors. The colors of C.M.Y.K Color are gradiated so that one form, texture, and colors are printed as if they were seen by the eye. C is blue series, M is red series, Y is yellow series, K is black series. The WAWA sticker of the present invention is offset printing on the first luminous flux in Korea, which is made by combining the function of Fluorescent Pigment and the characteristics of offset printing. One printing method.

The present invention is a printing method of offset printing on a fluorescent pigment that can see the shape or color of a picture even in a dark place. We will develop, manufacture, and sell products such as safety signs, nightly advertisements, decorations, and vehicle stickers.

WAWA sticker is screen printed by blocking white screen on hologram fabric, and then mixed with Fluorescent Pigment and soft transparent ink, and the screen printing is clean and simple by adding gold leaf. Gave as much as possible.

The WAWA sticker is a MAGIC STICKER partially utilizing the hologram feature to the fullest and the offset printing method is printed on the fluorescent pigment so that the shape and color of the picture can be seen in the dark even when it is bright.

It also gave a three-dimensional effect with gold leaf and epoxy treatment.

Claims (1)

[Independent Claims] It is the printing method that offset printing on Fluorescent Pigment for the first time, and the color and shape can be seen in the dark as if the picture of each sticker is bright.
