雖然紫外光清漆特殊的高亮度效果已經得到了大多數印刷技術人員的認可，但在印刷后的加工過程中，紫外光清漆的性能還不能滿足要求。目前紫外光清漆熱燙印適應性不成熟，熱燙印質量不穩定。主要原因是樹脂和紫外光清漆的成分不適合燙印。這些問題需要濟南包裝印刷廠家來。
Although the special high brightness effect of UV varnish has been recognized by most printing technicians, the performance of UV varnish can not meet the requirements in the process of post printing. At present, UV varnish hot stamping adaptability is not mature, hot stamping quality is not stable. The main reason is that the composition of resin and UV varnish is not suitable for hot stamping. These problems need to be solved by Jinan packaging and printing factory.
下面簡要分析一下開發和測試過程中紫外光油層密封的難點。
The following is a brief analysis of the difficulties in the development and testing process of UV reservoir sealing.
(1)為了形成高亮度的效果，紫外光清漆必須有一定的厚度，但漆層過厚不利于燙印。UV膠印涂料厚度一般大于9g/M。
(1) In order to form the effect of high brightness, UV varnish must have a certain thickness, but too thick paint layer is not conducive to hot stamping. The thickness of UV offset coating is generally greater than 9g / m.
(2)為了保證紫外光清漆的固化性能，需要在uv涂料中加入特殊的樹脂和大量的添加劑，這將不可避免的影響uv涂料表面熱沖壓的影響。
(2) In order to ensure the curing performance of UV varnish, special resin and a large number of additives need to be added to UV coating, which will inevitably affect the hot stamping of UV coating surface.
(3)目前紫外光漆樹脂組成與高溫高壓燙印箔的相容性不夠好，無法控制紫外光漆的燙印。
(3) At present, the compatibility between UV paint resin composition and high temperature and high pressure stamping foil is not good enough to control the stamping of UV paint.
因此，在印刷包裝中，在紫外光油表面燙印需要注意以下幾點。
Therefore, in the printing and packaging, we need to pay attention to the following points in the UV oil surface hot stamping.
(4)當需要增加紫外線油的亮度時，不增加光油層厚度的方法。通過調整涂布工藝參數(涂布輥線角、線數等)和印刷設備性能(印刷壓力、印刷速度等)，提高涂布層的平整度和亮度。
(4) When it is necessary to increase the brightness of ultraviolet oil, it is not recommended to increase the thickness of light oil layer. By adjusting the coating process parameters (coating roll line angle, line number, etc.) and printing equipment performance (printing pressure, printing speed, etc.), improve the smoothness and brightness of the coating layer.
(5)合理選擇沖壓材料，使橡膠層與紫外光清漆樹脂具有良好的親和力。
(5) Reasonable selection of stamping materials can make rubber layer have good affinity with UV varnish resin.
(6)準確調整熱版溫度和壓力，因為過高的壓力和溫度會損害油墨的表面性能，使燙印更加困難。同時，沖壓速度不宜太快。
(6) Accurately adjust the hot plate temperature and pressure, because too high pressure and temperature will damage the surface performance of the ink, making hot stamping more difficult. At the same time, the stamping speed should not be too fast.
