S1, tool component to be installed on the board of transfer printing equipment.Tool component has the working surface of setting, to contact the second surface 9 of matrix 4.In order to avoid second surface 9 is scratched by working surface, cover one deck anti-scratch layers at the working surface of tool component.This anti-scratch layers can be but be not limited at least one in polytetrafluoroethylene (PTFE) (PTFE), acrylonitrile-butadiene-styrene copolymer (ABS) and Kynoar (PVDF).As long as skid resistant course possesses the pliability of setting, any surface finish, not easily scratch matrix 4.The thickness of anti-scratch layers can design according to actual needs.Needed first anti-scratch layers to be set to working surface before placement matrix 4.Fixing to make anti-scratch layers to adopt bonding mode that anti-scratch layers is adhered to working surface.Certainly, also can adopt other connected modes, as Electrostatic Absorption etc., make skid resistant course be fixed on working surface.
S2, the first surface 8 of matrix 4 to be cleaned, to remove foreign material or dust.This step is most important for the effect of bat printing, if there is dust or particle, easily causes bat printing layer to occur pin hole even bulge, reduces the yields of product.
It should be noted that, matrix 4 has the first surface 8 and second surface 9 that are oppositely arranged.The material of matrix 4 can be but be not limited to plastic and glass, as long as transparent material, and can make the structure of setting as required.Generally, matrix 4 is sheet.Shape, the thickness of matrix 4 can design as required.In order to adapt to the development trend of cambering, matrix 4 comprises sphere, and wherein, first surface 8 is the concave surface of sphere, and second surface 9 is the convex surface of sphere.
One of the present invention preferred embodiment in, adopt the method for alcohol wipe to clean first surface 8.At least wiping 2 times during wiping.More preferably, can adopt but be not limited to long stapled non-woven fabrics and carry out wiping.The fiber difficult drop-off of this cloth, avoids the secondary pollution to first surface 8.The natural evaporation of alcohol wipe relief alcohol to form clean surface, or adopts the method for heating evaporation that alcohol is evaporated rapidly, as the method for drying.Should avoid again touching the first surface 8 after cleaning, to prevent secondary pollution.
S3, first surface 8 bat printing translucent printing ink at transparent matrix 4, to form ground floor 1.Specifically, first, lubricant plug is full of translucent printing ink; Then, steel plate shifts out, lubricant plug wiping, and glue head is pressed onto steel plate and gets ink; After the translucent printing ink that glue head is stained with, move after steel plate, again fill up translucent printing ink; Finally, glue head moves down, by the first surface 8 of translucent printing ink bat printing to matrix 4.Under normal circumstances, bat printing thickness does not once reach the requirement of pattern displaying, in order to increase the thickness of the translucent printing ink of ground floor 1 to reach the visual effect of setting, need carry out repeatedly bat printing, as bat printing 3 times.Ground floor 1 bat printing be translucent printing ink, this mileage is more weak.This ink can be but be not limited to the translucent printing ink of white, and the selection of ink colors should be selected according to the effect that will reach.Translucent printing ink can make the first pattern 5 present natural effect under natural daylight condition, as 3C color (PANTONE colour atla), makes the first pattern 5 present translucent bright color under background light illuminate condition.Those skilled in the art will appreciate that the light transmittance of translucent printing ink is at 50%-80%.The light transmittance of white translucent ink is higher than the light transmittance of colored translucent ink.More preferably, in order to improve display effect, the present invention adopts white translucent ink.The light transmittance of shaping rear ground floor is 50%-80%.
In order to accelerate the solidification of ink, after bat printing completes, ground floor 1 is dried, to form ground floor 1 fast.Product adopts pipelining, flows to next board, carry out the bat printing of the second layer 2 while oven dry.
S4, on ground floor 1, bat printing first hides ink, to form the second layer 2.With reference to Fig. 3, specifically, first, lubricant plug is full of the first covering ink; Then, the steel plate with the first pattern 5 shifts out, lubricant plug wiping, and glue head is pressed onto on steel plate and gets ink; Glue head moves after steel plate, again fills up the first covering ink after being stained with and hiding ink with first of the first pattern 5; Finally, glue head moves down, on the first pattern 5 bat printing to ground floor 1.It should be noted that, after the second layer 2 is shaping, the first pattern 5 is pierced pattern, and the region bat printing outside vacancy section 7 has covering ink.First of the second layer 2 hides ink and can be but be not limited to white covering ink.Those skilled in the art will appreciate that ink to the transmission effects of light with the thickness of ink layer, the color of ink and the color of light of irradiating relevant.The transmissivity of the thicker then light of ink layer is lower, and the transmissivity of the thinner then light of ink layer is higher.The ink of same thickness, the darker then light transmittance of its color is less, and the more shallow then light transmittance of color is higher.In visible-range, the penetrability of the longer then light of wavelength of light is stronger, and the penetrability of the shorter then light of wavelength of light is more weak.In order to make to hide the second pattern 6 under natural daylight, under background light, show the second pattern 6.One of the present invention preferred embodiment in, the light transmittance of the second layer after shaping is 20%-60%.
First hides the color of ink and thickness, can select according to actual needs, and as the colored ink such as yellow, blue, green, the present invention does not limit this.One of the present invention preferred embodiment in, first to hide ink be that white hides ink, and the thickness of the second layer of formation is 60-100 μm.White hides the display that ink is pattern and provides white background, and under natural daylight condition, the vacancy section areflexia light of the first pattern 5, presents grey or black, and white background can make the contrast of the first pattern more obvious, and display effect is better.
Under normal circumstances, bat printing once after, it is thinner that first of the second layer 2 hides ink, the first pattern 5 formed is unintelligible, and covering position can not form good covering to natural daylight, in order to increase the second layer 2 first hides the thickness of ink to reach the visual effect of setting, repeatedly bat printing need be carried out, as bat printing 2,3 or 4 times.It should be noted that repeatedly bat printing should ensure the registration of the first pattern 5.
Similarly, in order to accelerate the solidification of the first covering ink, after the second layer 2 bat printing completing, hiding ink to first and drying.Product adopts pipelining, flows to next board again, carry out the bat printing of third layer 3 while oven dry.
S5, on the second layer 2 bat printing second hides ink, to form third layer 3.With reference to Fig. 4, specifically, first, lubricant plug is full of the second covering ink; Then, the steel plate with the first pattern 5 and the second pattern 6 shifts out, lubricant plug wiping, and glue head is pressed onto on steel plate and gets ink; Glue head moves after steel plate, again fills up the second covering ink after being stained with and hiding ink with second of the first pattern 5 and the second pattern 6; Finally, glue head moves down, on the first pattern 5 and the second pattern 6 bat printing to the second layer 2.It should be noted that, after third layer 3 is shaping, the first pattern 5 and the second pattern 6 are pierced pattern, and the region bat printing outside vacancy section 7 has the second covering ink.First pattern 5 of the third layer 3 after shaping overlaps with the first pattern 5 of the second layer 2.The color of the first covering ink and thickness, can select according to actual needs.The present invention does not limit this.One of the present invention preferred embodiment in, second to hide ink be that grey hides ink, and the thickness of third layer formed is 25-50 μm.Preferably, in order to the covering effect reached, the light transmittance of the third layer after shaping is less than 20%.Grey hides the transmissivity that ink can reduce background light effectively, and can not hide ink generation interference to the white of the second layer.Thus make the display effect of the first pattern 5 and the second pattern 6 better.
Second hides the color of ink can select according to the effect that will reach, and as the colored ink such as yellow, blue, green, also can be white or black ink.Under normal circumstances, bat printing once after, third layer 3 is thinner, the dim design formed, and covering position can not form good covering to light, in order to increase third layer 3 second hides the thickness of ink to reach the visual effect of setting, repeatedly bat printing need be carried out, as bat printing 2,3 or 4 times.It should be noted that repeatedly bat printing should ensure the registration of the first pattern 5.
