To make the life more colorful
1,Color sample and color card control
The printed color samples of paper cards provided by customers must be strictly kept by special personnel. It is recommended to replace the color sample and color card every three months to achieve permanent hue, lightness and saturation.
2,Paper card printing from ink control
In the actual paper card printing process, it is necessary to control the viscosity and PH value of the ink.
3,Slave speed control
In the actual process of paper card printing, it is necessary to maintain a stable machine speed for production, and do not go too fast or too slow at the same time, especially for the roller scraping ink supply system. This is because the double ink roller ink transfer system is completed by extruding and rotating the two rollers with a certain linear speed difference. The speed of the printing machine is also an important factor that directly affects the printing color.
4.Printing pressure control from paper card
The contact pressure between the anilox roller and the printing plate, and the contact pressure between the printing plate and the paperboard. Therefore, in order to achieve the same color of the same batch of goods, the printing pressure is also an important factor to be controlled.
5.Make sure the anilox roll is clean
In addition to the above four points, make sure that the anilox roller of each printing unit is cleaned before printing the paper card. Because if the mesh hole of the anilox roller is blocked, the uniformity of ink transfer will be affected, and the printed images and texts will have uneven color.
6.Paper Color
The paper with different whiteness has different effects on the color appearance of the printing ink layer. Because different whiteness equals to adding different black, red, blue or yellow to the ink, although the ink volume and hue have not changed in the paper card printing, the actual ink has a certain transparency, and the color effect appears with the different whiteness of the paper, resulting in different color differences.
The quality of PVC Decorative Film directly determines the grade and performance of the finished blister door panel.
A good blister film should reach a certain thickness, the film back glue should be uniform, and the color should be stable.
If the thickness of the PVC film is low, there will be white phenomenon and orange peel phenomenon on the surface when covering the corners. In order to deal with these two phenomena, Marble Grain PVC Decorative Film Wholesale chooses to reduce the pressure of the plastic suction machine, which to some extent reduces the problem of white and plate deformation, but it is unable to ensure the bonding firmness of the PVC film and the substrate. The main problem caused by the uneven glue on the back of the film is that the PVC film and the base material cannot be bonded and pressed normally, and the PVC film itself cannot be bonded and pressed with the base material through the glue of the plastic suction machine. The glue must be rolled on the back during production, which we call the back glue. The uniformity of the back glue and the quality directly affect the adhesion and pressure between the PVC film and the base material.
Color problem is one of the most noticeable problems. Yellowing is an inevitable problem. However, the stability of PVC surface texture and color should be guaranteed, otherwise, color fading may occur during normal use.
Dilong Yongfu decorative film is widely used in automotive interiors, public places, floors, wall panels, doors, furniture, kitchen cabinets, speakers, integrated ceiling, whole house custom and outdoor curtain wall, roof color steel tile pressing and so on. Features include: indoor and outdoor weather resistance, scratch resistance, super sub, antibacterial, net taste, waterproof, etc., can meet different levels of environmental protection requirements.
