Abstract

The invention discloses a method for making pictures and texts have stereoscopic effects. Print the synthesized three-dimensional graphics on the paper first, and pre-make the distance and shape of the cylinder lenses that match the three-dimensional graphics in the ironing head of the hot stamping equipment, stick a film on the surface of the graphics, and press Finally, a grating is formed to produce a stereoscopic visual effect. After the finished printed matter is die-cut to the required shape on the die-cutting machine, it can be directly used as packaging material. Its visual effect is obvious, which is convenient for highlighting product features and corporate logos. It can be applied to the surface of most existing paper prints, regardless of folding, cutting or collage, it will not affect the visual performance of three-dimensional graphics. Compared with grating plate products, it has the characteristics of convenience, environmental protection, and easy mass production, and has a good market application prospect.

Description

The Method of Making Graphics and Texts Have Stereoscopic Effect

technical field

The invention belongs to the technical field of packaging printing, and in particular relates to a method for making graphics and text on the surface of a printed matter have a stereoscopic visual effect.

Background technique

Existing stereoscopic visual effect graphics and text production technology, first will print the graphics and texts processed with stereographic design software on the grating plate with corresponding cylinder lens spacing, and then use the grating plate as a whole to make the packaging box, or carry out the grating plate Cut out and stick to paper products. Due to the large thickness of the lenticular plate and its organic plastic material, it cannot usually be printed in batches on a printing machine, and cannot meet the packaging needs of mass-produced products. Therefore, it is generally used for single greeting cards and decorative paintings. In addition, these packages using grating plates are not easy to degrade in the natural environment, and will cause environmental pollution after being discarded. How to overcome these problems has not yet seen a good solution in the prior art.

Contents of the invention

The purpose of the present invention is to provide a convenient and environment-friendly method for making the graphic on the surface of the printed matter have a stereoscopic visual effect, aiming at the deficiencies of the prior art.

The purpose of the present invention is achieved through the following technical solutions.

A method for making pictures and texts have a stereoscopic visual effect, which is characterized in that: firstly, the synthesized three-dimensional pictures and texts are printed on paper, and a column matching the three-dimensional pictures and texts is made in advance in the ironing head of the hot stamping equipment. The distance and shape of the mirror, stick a film on the surface of the graphic, and form a grating after hot pressing.

The method specifically includes the following steps:

1. Select the required graphic and text, use the stereoscopic image design software, and process the graphic and text according to the data specification of 80lpi-200lpi;

2. Make printed files: make the output stereographics into unit files;

3. Typeset the unit file, after typesetting, the spacing between units should be a multiple of the width of the cylinder;

4. Carry out color separation and screen screening for typesetting files, and output four-color film plate making;

5. Print the graphic on the paper;

6. The ironing head of the hot stamping machine is made into a shape that matches the graphic. The positions coincide with each other, and a film is adhered to the surface of the graphic and text, and the lenticular grating is formed by hot pressing, so as to obtain the required graphic and text with a three-dimensional visual effect.

The transparency of the film is preferably 70% to 99%.

The thickness of the film is preferably 0.1 to 0.5 mm.

After printing the lenticular paper, die-cut the required shape on the die-cutting machine, and then it can be directly used as packaging material.

Compared with the prior art, the present invention has the following advantages: the method is simple, the cost is low, the visual effect is obvious, and it is convenient to highlight product features and enterprise logos. It can be applied to the surface of most existing paper prints, regardless of folding, cutting or collage, it will not affect the visual performance of three-dimensional graphics. Compared with grating plate products, it has the characteristics of convenience, environmental protection and easy mass production. This technology will help to change the form of the existing packaging and improve the level of packaging, especially for tobacco, wine, cosmetics, communications, IT and other products that have high requirements for packaging quality and a large demand for packaging boxes.

Detailed ways

The present invention will be described in further detail below in conjunction with embodiment, but they are not limitation of the present invention.

Example 1

Make pictures and texts with stereoscopic visual effects. Select the required graphic and text, use the three-dimensional image design software, and process the graphic and text according to the data specification of 80lpi. Make the output stereoscopic image and text into a unit file. The spacing between units after typesetting the unit file should be a multiple of the width of the cylinder. Perform color separation and screen screening on typesetting files, and output four-color film plate making. Print graphics on paper. Make the ironing head of the hot stamping machine into a shape that matches the three-dimensional graphics, and the surface of the ironing head has rib-shaped protrusions with a unit pitch of 80lpi. After sticking a film with a transparency of 70% on the surface of the graphic and text, place it in the hot stamping machine so that the position of the graphic and text coincides with the position of the ironing head. Under the conditions of a pressure of 300 tons and a temperature of 75°C, press for 0.5 seconds. The ironing head heats and deforms the film to form a shape matching the three-dimensional graphics and a lenticular grating of 80 lpi, so as to obtain the required printed matter with three-dimensional visual effects and graphics.

Example 2

Repeat Example 1, with the following differences: the data specification for graphic and text processing is 120lpi. The transparency of the film was 80%. Pre-made rib-shaped protrusions with a unit pitch of 120lpi on the surface of the iron. Set the pressure of the ironing machine to 700 tons, the temperature to 125°C, and press for 0.2 seconds to form a grating with a specification of 120lpi.

Example 3

Repeat Example 1, with the following differences: the data specification for graphic and text processing is 200lpi. The film transparency is 99%. Pre-made rib-shaped protrusions with a unit pitch of 200lpi on the surface of the iron. Set the pressure of the ironing machine to 1100 tons, the temperature to 200°C, and press for 0.01 second to form a grating with a specification of 200lpi.

Example 4

The printed matter that embodiment 1 obtains is die-cut out required shape on die-cutting machine, is used as cigarette packing box.
