彩色纸箱子一般全是4色之上的版面开展套印，且面巾纸的横着非常容易因自然环境的温度湿度转变而出現形变，导致套印禁止常见故障的造成。控制好印刷生产车间的温度湿度，变成提升彩色纸箱子商品套印精密度的重要一环。
Color paper boxes are usually overprinted on 4 colors, and the cross section of tissue paper is easy to deform due to the change of temperature and humidity in the natural environment, which leads to the common failure of overprint prohibition. Controlling the temperature and humidity of printing workshop becomes an important part of improving the overprint precision of color paper box products.
因此，无论是柔印加工工艺、平印或凹印生产线，生产制造当场的温度湿度都务必维持相对性的平稳和均衡，印刷全过程中不能出現显著的高矮差距状况，以防造成套印禁止的弊端。印刷加工工艺实践活动说明，印刷生产线的溫度一般控制在22℃上下，环境湿度应维持在60%上下，纸型、硬纸板不易出現形变状况，那样对不错确保商品的精确套印是较为合理的。
Therefore, no matter it is flexo printing process, lithography or gravure production line, the temperature and humidity on the production site must be kept relatively stable and balanced, and there should be no significant height gap in the whole printing process, in order to prevent the malpractice of overprint prohibition. The practice of printing process shows that the temperature of the printing production line is generally controlled at 22 ℃, and the ambient humidity should be maintained at 60%. The paper shape and cardboard are not easy to deform, which is good for ensuring the accurate overprint of commodities.
2、装版生产工艺控制。
2. Plate loading production process control.
选用胶印机对纸箱子面巾纸开展预印的生产工艺流程，装版实际操作技术性的控制非常关键。因为PS版较薄，其光感应层和版基的累计薄厚约为0.2mm，而且铝合金板的版基，原材料具备较脆的特点，在装版全过程时要留意慎重实际操作，上版时要留意防止版面被设备上的构件刮伤；
Using offset press to carry out preprinting process for box tissue paper, the technical control of actual plate loading is very important. Because the PS plate is thin, the cumulative thickness of its light sensing layer and plate base is about 0.2mm. Moreover, the raw materials of the plate base of aluminum alloy plate have the characteristics of brittleness. In the whole process of plate installation, pay attention to the practical operation, and pay attention to prevent the plate from being scratched by the components on the equipment;
校版拉版时要留意把握适当用劲，避免用力过猛而使印刷版出現拉申形变，导致商品套印禁止和耐印率降低。柔版装版要留意尽可能一次性指向粘版部位，防止不断拆版使印刷版形变和危害粘版的色牢度。
When proofreading and printing, we should pay attention to the proper use of force to avoid drawing deformation of the printing plate due to excessive force, resulting in the prohibition of overprinting and the reduction of printing endurance. Flexographic mounting should pay attention to the one-time point to the sticky part as far as possible, to prevent the continuous plate breaking deformation and damage the color fastness of the plate.
当平均气温非常高时，应考虑到选用高品质的泡沫双面胶，避免印刷全过程中印刷版出現走位常见故障。高品质的泡沫双面胶布应该是黏度强，平面度好，薄厚匀称，耐热性能优良，能保证 在高、超低温工作自然环境下维持黏度的可靠性，拆版时版材和版滚桶没留胶痕。
When the average temperature is very high, we should consider the choice of high quality foam double-sided adhesive to avoid common faults in printing process. High quality foam double-sided adhesive tape should be strong viscosity, good flatness, thin and well proportioned, excellent heat resistance. It can ensure the reliability of maintaining viscosity in high and ultra-low temperature working environment.
3、胶版印刷墨笔画均衡的控制。墨笔画均衡的控制是胶版印刷加工工艺关紧要的一个技术性阶段，在印刷面巾纸时经常由于墨笔画均衡控制不及时，危害淡墨品质的状况不缺出現，因而在印刷全过程中，要以尽可能小的润版液需求量，在维持墨笔画均衡的标准下开展理想化的印刷，切勿选用“墨洪水也大”的均衡法开展印刷。
3. Offset printing ink painting balance control. The control of ink brush balance is a crucial technical stage in offset printing process. When printing facial tissue paper, due to the untimely control of ink balance, there is no lack of damage to the quality of light ink. Therefore, in the whole process of printing, it is necessary to carry out ideal printing with the minimum amount of fountain solution as possible under the standard of maintaining ink and brush balance“ Ink flood also big "balanced method to carry out printing.
墨笔画均衡控制的关键所在，规定油墨保持稳定的洁净度和有效的流通性，要尽可能无需或者少用催干剂，避免油墨初期干躁出現的起膜状况；印刷生产车间要注意防尘、防粉维护；要尽量减少新老油墨互用；润版液PH值控制要适度，水体要维持纯粹；胶棍和水辊务必保持稳定的精密度和适度的强度；印刷速率要维持适度和稳定，这种全是完成墨笔画均衡的技术性要点和合理确保标准。
The key to the balance control of ink and brush painting is to stipulate that the ink should keep stable cleanliness and effective circulation, and the drying agent should be avoided as much as possible, so as to avoid the film forming condition of the ink in the early stage of dryness; the printing workshop should pay attention to the dust and powder proof maintenance; the new and old inks should be used as much as possible; the pH value of fountain solution should be controlled appropriately, and the water body should be kept pure; rubber stick and water roller should be kept It is necessary to maintain stable precision and moderate strength, and to maintain moderate and stable printing speed, which are the technical points and reasonable assurance standards for completing the balance of ink and brush painting.
4、胶版印刷印刷色序分配的控制。
4. Control of color sequence distribution in offset printing.
彩色纸箱定做的印刷一般全是选用多色印刷机一次进行印刷的，印刷时油墨是在一瞬间进行“湿压湿”的叠印和套印的，各色各样中间叠压的時间非常短，因此，印刷色序应依据版面构造、油墨特点和纸型特性等众多要素有效明确。
The multi-color printing machine is generally used for one-time printing of color cartons. When printing, the ink is used to overprint and overprint in a flash, and the time of intermediate lamination of various colors is very short. Therefore, the color sequence of printing should be effectively defined according to the layout structure, ink characteristics and paper type characteristics.
一般来说，印刷色序的分配应依据具体情况酌情考虑把握，如将印刷总面积和墨量小的先印，版面和墨量大的后印；清晰度差的油墨先印，清晰度好的油墨后印；黏度大的油墨先印，黏度小的油墨后印；偏干慢的油墨先印，干躁速度更快的油墨后印。
Generally speaking, the distribution of printing color sequence should be considered according to the specific situation, such as printing the printing with small total printing area and ink quantity first, printing after printing with large layout and ink volume; printing ink with poor clarity first, printing with ink with good clarity; printing with high viscosity first, printing with oil ink with low viscosity; printing with slow drying ink first, printing with ink with faster drying speed.
