步骤1：制作定位电化铝，步骤如下：Step 1: Make positioning anodized aluminum, the steps are as follows:
(1)在聚酯薄膜上采用水蜡涂布离型层，形成半成品接装纸；(1) Use water wax to coat the release layer on the polyester film to form semi-finished tipping paper;
(2)在半成品上采用12色凹版印刷机印刷图案和制作定位标；(2) Use a 12-color gravure printing machine to print patterns and make positioning marks on the semi-finished product;

(7)将成品进行分切、包装形成成品定位电化铝。(7) Slitting and packaging the finished product to form finished product positioning anodized aluminum.
步骤2：接装纸烫金，步骤如下：Step 2: Bronzing the tipping paper, the steps are as follows:
(9)制作与定位电化铝相互配合的烫金版，将烫金文字或图案定位与电化铝颜色烫印位置相互配合；(9) Make a hot stamping plate that cooperates with the positioning of the anodized aluminum, and coordinate the hot stamping text or pattern positioning with the hot stamping position of the anodized aluminum color;
(10)将接装纸放置在烫金设备上，再将制作完成的烫金版固定到烫金设备的辊筒上；(10) place the tipping paper on the bronzing equipment, and then fix the finished bronzing plate on the roller of the bronzing equipment;
(11)将步骤1制作的定位电化铝安装在烫金设备上，设定烫金温度、接装纸烫印压力、烫金收卷处辅助压辊压力和烫印接装纸车速；(11) The positioning anodized aluminum made in step 1 is installed on the hot stamping equipment, and the hot stamping temperature, the hot stamping pressure of the tipping paper, the auxiliary pressing roller pressure at the hot stamping rewinding place and the speed of the hot stamping tipping paper are set;
(12)打开烫印设备对接装纸进行定位烫印。(12) Turn on the hot stamping equipment to perform positioning hot stamping on the butt-loaded paper.
烫金版辊面为铜合金层，铜合金层的厚度大于12mm，烫金版辊面粗糙度小于0.4μm，烫金文字或图案与定位电化铝颜色烫印位置匹配，便于电眼对色块的精准扫描，实现烫印过程的精准烫印，保证烫印过程中的电眼跟踪。接装纸烫印温度范围为180-240℃，温度过低定位电化铝离型层和胶粘层熔化不充分会造成烫印不牢固或印记不完整，烫印温度不低于定位电化铝的耐温范围，温度过高则使得具有热熔性能的膜层超范围熔化，进而致使印记周围也随着定位电化铝而产生糊版，根据定位电化铝的性能、烫印压力、车速、烫印面积、印刷品底色墨层颜色和厚度等将接装纸的温度范围确定为180℃-240℃，确定最佳的设定温度后尽可能保持温度的恒定，以使得同批次的产品质量稳定。在定位电化铝上施加压力保证定位电化铝能够附在承印物上，并对定位电化铝烫印部位进行剪切，烫印压力过小将无法使得定位电化铝与接装纸粘附，同时对烫印边缘无法充分剪切导致图案烫印不上或烫印部位印迹不清晰，压力过大烫印设备上的衬垫和接装纸的压缩变形增大会产生印迹变粗，因此将接装纸烫印压力范围为0.2-0.6MPa，烫金收卷处辅助压辊压力范围为0.2-0.4KPa。烫印速度决定了定位电化铝和接装纸之间的接触时间，接触时间决定了烫印图案牢固程度，烫印速度越慢越有利于定位电化铝和接装纸粘结牢固，烫印接装纸车速过快会导致定位电化铝的热熔性膜层在脱落的瞬间尚未熔化或者熔化不充分，进而造成烫印不上图案，结合烫印的压力、温度，将接装纸车速范围为50-110米/分钟，以保证烫印的牢固程度和烫印效果。The roll surface of the hot stamping plate is a copper alloy layer, the thickness of the copper alloy layer is greater than 12mm, and the roughness of the hot stamping plate roll surface is less than 0.4μm. Accurate hot stamping in the hot stamping process is realized, and the electric eye tracking in the hot stamping process is guaranteed. The hot stamping temperature range of tipping paper is 180-240℃. If the temperature is too low, the positioning of the anodized aluminum release layer and the adhesive layer will not melt enough, which will cause the hot stamping to be weak or incomplete. The hot stamping temperature should not be lower than the positioning of the anodized aluminum. Temperature resistance range, if the temperature is too high, the film layer with hot-melt performance will melt beyond the range, and then the surrounding area of the mark will also generate paste with the positioning of the anodized aluminum. The temperature range of the tipping paper is determined as 180℃-240℃ according to the area, the color and thickness of the ink layer of the bottom color of the printed matter, etc. After determining the best set temperature, keep the temperature as constant as possible, so as to make the product quality of the same batch stable. . Apply pressure on the positioning anodized aluminum to ensure that the positioning anodized aluminum can be attached to the substrate, and cut the hot stamping part of the positioning anodized aluminum. The imprinting edge cannot be cut sufficiently, so the pattern cannot be hot stamped or the imprint of the hot stamping part is not clear. If the pressure is too high, the compression deformation of the pad and the tipping paper on the hot stamping equipment will increase, which will cause the print to become thicker. Therefore, the tipping paper will be hot. The printing pressure range is 0.2-0.6MPa, and the pressure range of the auxiliary roller at the bronzing rewinding place is 0.2-0.4KPa. The hot stamping speed determines the contact time between the positioning anodized aluminum and the tipping paper, and the contact time determines the firmness of the hot stamping pattern. Too fast loading speed will cause the hot-melt film layer of the positioning anodized aluminum to be not melted or insufficiently melted at the moment of falling off, which will cause the pattern not to be stamped. Combined with the pressure and temperature of the stamping, the speed range of tipping paper is 50-110 m/min to ensure the firmness and effect of hot stamping.
综上所述，在本实施例中，按照本实施例的定位烫印接装纸制备方法，通过12色凹版印刷机能够在离型层上印刷出复杂精美的图案，能够赋予印刷图案丰富的层次感和更加复杂的精美图案，透明黄成膜性、耐热性和透明性优良，有助于镭射图标和定位标的模压，热塑性树脂能够在涂布机上受热熔化在镀铝层上形成胶粘层。烫金版辊面为铜合金层，铜合金层的厚度大于12mm，烫金版辊面粗糙度小于0.4μm，烫金文字或图案与定位电化铝颜色烫印位置匹配，便于电眼对色块的精准扫描，实现烫印过程的精准烫印，保证烫印过程中的电眼跟踪。接装纸烫印温度范围为180-240℃，温度过低定位电化铝离型层和胶粘层熔化不充分会造成烫印不牢固或印记不完整，烫印温度不低于定位电化铝的耐温范围，温度过高则使得具有热熔性能的膜层超范围熔化，进而致使印记周围也随着定位电化铝而产生糊版，根据定位电化铝的性能、烫印压力、车速、烫印面积、印刷品底色墨层颜色和厚度等将接装纸的温度范围确定为180℃-240℃，确定最佳的设定温度后尽可能保持温度的恒定，以使得同批次的产品质量稳定。在定位电化铝上施加压力保证定位电化铝能够附在承印物上，并对定位电化铝烫印部位进行剪切，烫印压力过小将无法使得定位电化铝与接装纸粘附，同时对烫印边缘无法充分剪切导致图案烫印不上或烫印部位印迹不清晰，压力过大烫印设备上的衬垫和接装纸的压缩变形增大会产生印迹变粗，因此将接装纸烫印压力范围为0.2-0.6MPa，烫金收卷处辅助压辊压力范围为0.2-0.4KPa。烫印速度决定了定位电化铝和接装纸之间的接触时间，接触时间决定了烫印图案牢固程度，烫印速度越慢越有利于定位电化铝和接装纸粘结牢固，烫印接装纸车速过快会导致定位电化铝的热熔性膜层在脱落的瞬间尚未熔化或者熔化不充分，进而造成烫印不上图案，结合烫印的压力、温度，将接装纸车速范围为50-110米/分钟，以保证烫印的牢固程度和烫印效果。To sum up, in this embodiment, according to the preparation method of positioning hot stamping tipping paper in this embodiment, complex and exquisite patterns can be printed on the release layer by a 12-color gravure printing machine, which can give rich printing patterns. Layered and more complex and exquisite patterns, transparent yellow, excellent film-forming, heat resistance and transparency, it is helpful for the molding of laser icons and positioning marks, thermoplastic resin can be heated and melted on a coating machine to form adhesive on the aluminized layer Floor. The roll surface of the hot stamping plate is a copper alloy layer, the thickness of the copper alloy layer is greater than 12mm, and the roughness of the hot stamping plate roll surface is less than 0.4μm. Accurate hot stamping in the hot stamping process is realized, and the electric eye tracking in the hot stamping process is guaranteed. The hot stamping temperature range of tipping paper is 180-240℃. If the temperature is too low, the positioning of the anodized aluminum release layer and the adhesive layer will not melt enough, which will cause the hot stamping to be weak or incomplete. The hot stamping temperature should not be lower than the positioning of the anodized aluminum. Temperature resistance range, if the temperature is too high, the film layer with hot-melt performance will melt beyond the range, and then the surrounding area of the mark will also generate paste with the positioning of the anodized aluminum. The temperature range of the tipping paper is determined as 180℃-240℃ according to the area, the color and thickness of the ink layer of the bottom color of the printed matter, etc. After determining the best set temperature, keep the temperature as constant as possible, so as to make the product quality of the same batch stable. . Apply pressure on the positioning anodized aluminum to ensure that the positioning anodized aluminum can be attached to the substrate, and cut the hot stamping part of the positioning anodized aluminum. The imprinting edge cannot be cut sufficiently, so the pattern cannot be hot stamped or the imprint of the hot stamping part is not clear. If the pressure is too high, the compression deformation of the pad and the tipping paper on the hot stamping equipment will increase, which will cause the print to become thicker. Therefore, the tipping paper will be hot. The printing pressure range is 0.2-0.6MPa, and the pressure range of the auxiliary roller at the bronzing rewinding place is 0.2-0.4KPa. The hot stamping speed determines the contact time between the positioning anodized aluminum and the tipping paper, and the contact time determines the firmness of the hot stamping pattern. Too fast loading speed will cause the hot-melt film layer of the positioning anodized aluminum to be not melted or insufficiently melted at the moment of falling off, which will cause the pattern not to be stamped. Combined with the pressure and temperature of the stamping, the speed range of tipping paper is 50-110 m/min to ensure the firmness and effect of hot stamping.
