For ink jet-print head being ejected into the ink rapid curing on thing to be printed surface, a UV solidification equipment is set on the side of each ink jet-print head in the present invention, in the present invention can also print dolly two ends or wherein one section a UV solidification equipment is set.
The Method of printing of colored bump maps picture of the present invention or word comprises, inkjet-printing device shown in one Fig. 1 is provided, by print software, print image is automatically generated and consisted of multiple figure layers, by ink jet-print head multipass (PASS) ink layer that superposes, make print thickness increase to form bump maps picture or word on thing to be printed surface, and after stack multipass (PASS) ink layer, by automatic adjusting thing to be printed, settle platform to make ink jet-print head and thing to be printed settle the distance between platform to increase, to prevent bump maps picture or word and ink jet-print head collision.
During inkjet printing, ink jet-print head injection multipass (PASS) ink layer superposes and forms bump maps picture or word on thing to be printed, and the front one deck ink layer in the multilayer ink layer of bump maps picture was all solidified before lower one deck ink layer is sprayed.Wherein also in the end one deck ink layer is curing together after spraying for the multilayer ink layer of bump maps picture, because now ink layer thickness is larger, higher to the power requirement of UV solidification equipment.Due to when China ink amount is saturated to a certain degree, UV ink cured effect weakens, and can affect print quality and solidification effect, and therefore, in the situation that UV lamp is constant, the China ink amount that need to print single pass limits.
In the present invention, the thickness of multiple-pass printing ink layer need to come to determine by experiment.Experiment parameter can be kept in ink thickness map, has had experiment parameter, just can be similar to the needed China ink amount while printing desired thickness that calculates, thus known printing pass.The thickness of individual layer ink layer is subject to the impact of the factors such as print resolution, color mode, sizes of ink dots, ink characteristics, ink jet-print head parameter and UV lamp.
When making ink thickness curve, first print and measure the color lump figure that ink is used, the thickness of printing due to the ink single pass of every kind of color has bigger difference, can not in a color lump, complete, point four groups of color lumps in the present invention, one is CMYK color separation color lump (color lump China ink amount 100%), two is chalk color lump (color lump China ink amount 100% or 200%, specifically by the quantity of spraying chalk ink jet-print head, determined), three is the compound color lump of CMYK (color lump China ink amount 400%), four is the compound color lump of CMYKW (color lump China ink amount 500% or 600%, specifically by the quantity of spraying chalk ink jet-print head, determined).These four groups of color lumps are respectively by 1,2,5,10,15,20,30,40, and 50 times stacks are printed, and obtain respectively four suite lines.Wherein CMYK color separation is four build-up curves.Be equivalent to altogether 7 curves.This curve, for printing pass, is laterally longitudinally ink thickness, according to this curve, can draw printing pass value required when needing thickness.
