Nowadays, the widespread use of three-dimensional printing is becoming more and more demanding. But what are the main points that affect stereo printing, are you clear? Now Amway Mall analyzes the five elements and three requirements that affect three-dimensional printing.
1. Three requirements for three-dimensional printing
1) Based on offset printing technology, the amount of coated paper for printing is not less than 250g/m2;
2) The printing ink is pure, high temperature resistant and fast drying;
3) The number of screened lines is not less than 300 lines/inch or is made with the Jurassic version.
2. Five elements of three-dimensional printing
1) Data unification: the original, pixel data and printed image are always consistent with the lenticular grating pitch, avoiding interference fringes in the finished image due to the difference of data, affecting the visual effect.
2) Overprinting accuracy: the error between the pixel and the grating must not exceed 0.0001‰. Because of the deviation of any color version, it will produce a clear image of the different color image when the grating is composited, so that the full color, the image is divorced and cannot be viewed.
3) Rich in layers: the printing outlets are clear, full, dense and unobtrusive, and not lost. If the network is out of control, it will cause polarization polarization, affecting the ideal reproduction of image stereo and space.
4) It is strictly forbidden to expand and contract: The experience of Anmei Mall strictly controls the amount of stretch of printed matter, which is the key to ensure the perfect reproduction of stereoscopic images. The printed image is stretched and stretched out of the barrier of the grating, resulting in a change in the visual positioning of the image, and an anti-image, a mis-image and a visual stun.
5) Adjust the angle of the network cable: the difference between the angles of the three-dimensional printing network lines should be smaller than the ordinary offset printing, such as the line angle of 300 lines/inch is K37.5°C37°, m20°, Y22.3°, the purpose is to make the dot combination In the cylindrical surface of the lenticular grating, the horizontal arrangement of the color lines is formed to ensure the balanced transition of the color image level, and the collision plate is prevented from being generated due to the equal angle of the mesh line and the vertical grating stripe, and abnormal moiré occurs, which affects the smooth reproduction of the color stereo image.
