Talk about the three-dimensional printing technology requires five elements 01. Three-dimensional printing requirements
1) technology-based offset printing with coated paper quantitatively not less than 250g / m;
2) Printing ink pure, high temperature resistant, fast drying;
3) increase the number of lines is not less than 300 lines / inch or using collotype production.
2. Five Elements of three-dimensional printing
1) Data unification: the original pixel data and printing image is always maintained unity with the lenticular pitch, to avoid the difference data of the interference fringes in the finished image, the visual effects.
2) overlay accuracy: error pixel raster shall not exceed 0.0001 ‰. Because any deviation from a color version, will be in the compound when the grating, resulting in significant Harmonia ghost image, make full map color, like divorce, unable to watch.
3) the level of rich: print outlets clear, full, close does not paste, sparse and not lost. Such as network control, ideal density will cause polarization, affecting the image reproducing three-dimensional space.
4) Do not stretch: strict control prints amount of stretching is key to ensuring perfect reproduction of the stereoscopic image. Telescopic printed image will be out of the grating pitch constraints, resulting in changing the image of visual orientation, appears a reverse image, like a wrong sense of vertigo and visual.
5) Adjust the screen angles: three-dimensional printing screen angle difference of colored version should be less than ordinary offset printing, screen angles such as 300 lines / inch of K37.5 ° C37 °, ㎡0 °, Y22.3 °, the purpose is to make the network a combination In lenticular cylinder to form the color line horizontal arrangement, ensure a balanced level of color like transition, to avoid the screen angle perpendicular to the grating strips equal and produce hit version, abnormal moire affect smooth color stereoscopic image reproduction.
