Influence of paper and process used by Yuelong, a carton packaging manufacturer, on Printing
1] characteristic analysis and process determination method of printed matter
Take packaging as an example. The specifications of internal and external packaging materials of the same product or the printing materials used in complete sets of products are very different. Although the layout structure or color of Dongguan printing factory are similar, there are also differences in materials and specifications, which makes the adaptability of printing process different. In the corrugated box, white board paper, kraft paper, cow leather card, white card and copper card are used. The corrugated plate is very thick and the surface layer is relatively flat. If considering the material characteristics and the safety and health of product packaging, it is recommended to use flexographic printing water-based ink, which can well ensure the printing quality of finished products. For the materials such as case surface paper, carton white cardboard, kraft paper, laser paper and so on, the gravure or flexographic printing process is generally adopted for large quantity, so the quality will be better controlled.
2] production and process control of color prepress
Now printing saves a lot of time. In the past, Dongguan printing manufacturers produced documents for customers themselves. Now they entrust advertising companies of third-party companies and their own internal designers to complete the original. The problem is that they are only limited to the perfection of the original and do not know or know the printing technology, The produced documents can not meet the requirements of printing technology. In the layout series of anilox structure, the printing color will be very different due to different materials. The same offset printing technology prints paper butterfly and paper cup, which have smooth surface and less ink absorption, and the surface area of the other paper is relatively rough. This kind of printing material with the same color.
3] Printing color can also be controlled by printing pressure
Printing pressure is the medium of printing transfer. The size of printing pressure directly reflects the depth of printing ink, especially relief printing technology. The size of pressure used by Dongguan printing manufacturers has a great impact on the depth of printing ink. When the printing pressure increases, the printing color will become darker. On the contrary, if the printing pressure is reduced, the printing color will become lighter, and the printing pressure will be adjusted appropriately, In color printing, different ink colors can also control the quality, and the printing quality of material series can be controlled differently. In order to control the printing quality of different materials, we must comprehensively consider the links such as material characteristics, technology and equipment operation adjustment, carefully analyze the original and determine the appropriate production technology scheme.
