The specific embodiment
Caloric transfer printing technology on the sheet metal may further comprise the steps:
1) with hot transfer ink with the picture and text offset printing on uncoated paper, paper can adopt the wood-free paper of 70g, hot transfer ink has the heat sublimation performance, reach specified temp and after the time ink molecules can evaporate, transfer on the stock;
2) printing surface with paper contacts with the coat side that cated sheet metal is set, with heating element heater homogeneous heating on sheet metal of Pyrograph machine; The sheet metal here can adopt aluminium sheet, copper coin or iron plate etc., and the coating that arranges on the sheet metal is PE polyester paint, and this coating can be good at absorbing ink molecules, and can merge mutually with ink molecules, forms firmly and color picture and text true to nature after merging; Pyrograph machine adopts the full-automatic four station Pyrograph machines of positive section, and on sheet metal during homogeneous heating, pressure is set to 7kg/cm with the heating element heater of Pyrograph machine
2, temperature setting is set to 175～230 degree, heats after 15～35 seconds, and the ink molecules volatilization enters sheet metal surface, and the picture and text that namely print on the paper are transferred to the coat side of sheet metal;
3) after heating was finished, because the heat sublimation performance of hot transfer ink, the picture and text that print on the paper were transferred to the coat side of sheet metal, end of operation; Owing to be printing ink heat sublimation molecular diffusion, printing ink and product after the moulding combine together, so product is in traditional offset printing effect that matches in excellence or beauty, the characteristic such as have high-temp resisting high-humidity resisting, uvioresistant, resistance to wear.
In the printing process there be several factors of major effect color: printing ink, paper, sheet metal, ink film thickness and drying condition.Reach the consistency of colour requirement, must select the raw material of good stability: printing ink, paper and sheet metal, according to the difference of different product ink film thickness (total ink), be more than 24～48 hours drying time simultaneously.
For reaching color effects true to nature, avoid producing deviation in the process of color transfer, must control the color of printing in the seal pretreatment process, the color control of printing adopts color management software to realize, this software adopts the GMG color management system, and concrete steps are as follows:
