Description
Technical field
The utility model relates to a kind of spray medium transfer paper, belongs to packaging material field.
Background technology
Paper-packed products accounts for the share of whole total package industrial output nearly 30%, and become the maximum main industry of packaging, the consumption figure of China's package paper and cardboard accounts for more than 50% of paper industry product population.Chinese market paper consumption figure is 14% of global total amount, is only second to the U.S. in the whole world, rank second place of the world.Along with improving constantly of people's living standard, common art post paperboard opens the esthetic requirement that printing effect cannot meet people, product also needs characteristic and attractive packaging to promote the desire to purchase of consumer simultaneously, so there are a kind of Novel paper packaging material of aluminium-plated transfer paper by name in recent years, because it has possessed the gloss of metal and various laser effect of dazzling the eyes, again a kind of environment-friendly package material simultaneously, so be widely used in all kinds of cosmetics, tobacco and wine packaging and fast-moving consumer goods packaging, obtain liking of consumers in general.
The production technology of current aluminium-plated transfer paper is mainly: on basis film, coat transfer resin, the coat side of film is directly aluminized, or be installed with for by thermal shift assay, hologram pattern being transferred on film transfer resin bed through certain moduli, and then aluminize, aluminium coated transfers to paper surface by glue the most at last, now paper is as the carrier of information, the processing such as normal printing can be carried out at its surface layer, or directly manufacture various package, so-called aluminium-plated transfer paper that Here it is.Aluminium-plated transfer paper is mainly divided into the aluminium-plated transfer paper of laser holographic and the aluminium-plated transfer paper of gold, silver card, although aluminium-plated transfer paper due to its metallic luster and laser effect very popular, but when printing, there is certain difficulty, only have and the metal sense of paper and laser effect could be set off out by UV printing, if but the texture of aluminium-plated transfer paper has been set off at some position and effect can form interference to the word of printing or pattern, is particularly reflected in the printing of bar code and Quick Response Code.Because these two kinds of bar code printings necessarily require code and background color to have obvious aberration, such could scan time distinguish, so usually adopt the printing matched combined of chalk bottoming and black code, and it is very high to print chalk requirement in aluminium-plated transfer paper, particularly usually need print that chalk just can be made for twice to print for offset printing equipment in fact the laser holographic effect of base stock and metal-like all to be hidden, reach such effect very high for the requirement of printing equipment, must possessing more colour cell, just to complete one-step print shaping, and some printing enterprises that equipment colour cell is less or production scale is less, can only by first printing chalk or print twice chalk on monochromatic gravure equipment in common offset machine, again go up offset press after having printed again and print other colour cells by UV, so many one production processes, energy consumption is caused to increase, operation loss is wasted, the various problems such as production efficiency reduction.
Application number be 201210180817.2 Chinese patent literature disclose a kind of laser transfer paper printed bar code after technique for grinding easy to identify, eliminated by the pattern adopting the mode of polishing will have holographic effect in laser master plate, repeat print during printing chalk before making and bring up to online print for twice and brushed one times.This method is by making radium raster eliminate laser plate polishing, position after polishing is the effect presenting sub-light, but follow-up printing needs make polishing position and chalk print position carries out alignment, once alignment is bad, to expose sub-light part will be very ugly, and said method due to be process holographic laser version so be only applicable to holographic aluminium paper, if directly utilize the gold and silver card aluminium paper of the aluminium-plated production of film, can not head it off, still can only by the enough hiding rare of printing twice chalk guarantee.
