Accuracy at the time of loading
The installation of flexographic printing plates has special requirements compared to offset printing. For example, the printing plate must be firmly adhered to ensure that it does not fall out of print during the printing process, and the plate must be able to be easily and conveniently removed from the platen. , In order to save the printing plate; Temperature, weather resistance is good, in the temperature of 40 degrees below the sticky version, not off version. Although there is the cooperation of the platecutters, human factors are very influential. For example, if the platers are not careful, double-sided adhesive wrinkles or bubbles appear, which will seriously affect the printing quality and even cause the plate to be scrapped. The material is flexible, and its ductility and elasticity are far more than that of offset printing plates. If the elongation of each plate is inconsistent, overprinting will be inaccurate and printing failures will occur. The installation of the flexographic printing plate must be successful at one time, otherwise it will be removed and reinstalled, which will also cause the amount of elongation to change. At the same time, the operator must maintain the tension of the plates in the installation process. In addition, operators should also be careful to operate in strict accordance with the operating specifications. For example: wipe the plate with alcohol before printing, because oil, fingerprints, and other foreign materials will damage the printing quality; take the printing plate should take the diagonal or both ends, so that the center of the plate on the double-sided tape, for To prevent it from tilting or warping, apply a hand to gently flatten the plate from the center to the head and from the center to the tail.
Double-sided adhesive selection
Double-sided adhesive substrate can be divided into low density, medium density, high density and hard quality. For the choice of type, which type of double-sided adhesive, in addition to considering the viscosity, the factors that should also be considered are: 1 docileness. If the double-sided tape is too hard, it will not only fail to be docile and may also generate air bubbles on the drum, too soft and not easy to use and accompanied by air bubble generation; 2 the properties of the plate. The requirements for stickiness of natural rubber and synthetic rubber plates are different; 3 intermediate substrates. For vinyl based hard substrates, which are consistent in thickness and conformability, some types of printing have been used so far, but some types of printing must use flexible double-sided tape. In general, the choice of double-sided adhesive should be changed dynamically according to the type of media, and it is necessary to ensure that the printing plate can be firmly bonded, but also to consider the cost, ease of operation and so on. Conventionally, low-density double-sided adhesives are used for high-quality color printing and line printing, medium-density double-sided adhesives are used for color printing, and high-density and rigid double-sided adhesives are used for line and full-plate printing. Operators should choose double-sided adhesives based on various factors in consideration of actual conditions.
Ink deployment
The quality of the ink is a decisive factor in the quality of the print. Therefore, the operator's ink viscosity and pH are particularly important. The ink viscosity, pH and alkalinity should be adjusted according to the different properties of the paper and different printing conditions. The printing viscosity of the ink depends on the colorant, the resin, the area of ​​the printing image, the properties of the printing material, and the printing speed of the constituent ink.
The choice of printing color sequence
The color sequence printed in flexo printing should not be the same, especially for multicolor screen printing, the factors that should be fully considered in the selection of printing color sequence are:
1 printability. There are several possibilities due to overprinting of ink. One is that the lower layer ink is moderately dry; the second is that the lower layer ink is excessively dry, resulting in a "vitrification" phenomenon; the new layer of ink is printed on a dot to shrink, and even the underlying ink cannot be printed, resulting in a printing failure;
2 changes in the color of the law. Because printing is a subtractive method, printing color sequence has little effect on high-profile color mixing, and has a great influence on dark tone.
3 ink transparency. The ink has a certain hiding power. After the printing ink is superimposed on the printing ink, it will affect the color rendering.
4 screen features. In general, the area with a small dot area is printed first, and the area with a large dot area is printed. The printing plate with the main color tone on the screen can be printed on or after the printing. Operators should choose the color sequence of printing based on a thorough analysis of various factors.
Adjustment of printing pressure
Offset printing pressure can be regulated quantitatively, there are certain operating regulations to follow, and the pressure can be quantitatively reflected. Flexographic printing itself is light pressure printing. Small changes in pressure can cause great fluctuations in printing quality. The adjustment of flexographic pressure cannot be quantitatively expressed, and can only qualitatively follow the “feeling†of operators. This requires The printing staff has a wealth of experience, accurate judgment ability and high sensitivity to color. Only in this way can we know which printing plate is under pressure and how much bigger according to network expansion and color, and whether the pressure of four printing plates is the same. In our study of Shaanxi Provincial Education Commission’s scientific research project—flexo printing is a mathematical model of color rendering, we used the United States Joint Flexographic Machine as our first printing plant in Xi’an, Shaanxi Province, and the pressure was very good. Control, so that the network expansion is very small, high-light part is not lost, the dark tone part does not paste version, from the film to the proofs of the network expansion rate of up to 8%, to achieve the effect of offset. In addition to advanced equipment, this is inseparable from the superb level of experience of workers.
The choice of printing speed
The printing speed of the flexo printer also has a significant effect on the expansion of the dot. The choice of speed is also a complicated matter. It should take into account the properties of the ink, especially the viscosity and dry handling, and the tensile strength of the printing material, when printing. Tension, machine performance and other factors. The unit type flexographic printing press is generally not ideal for overprinting at low speeds. This is because the friction resistance and inertia of various parts of the machine are not stable at low speed (15 m/min), but the effect is better when the speed is high, so the operator When the machine is at a low speed, rough adjustment of overprinting should be completed as soon as possible, and then the speed (50 m/min) should be increased. However, speed should not be pursued blindly. If it is handled improperly, it will be counterproductive.
Control of print tension
Tension is another topic of flexographic printing. It directly affects the accuracy of overprinting and determines the reject rate. The tension control should be matched with the printing speed and the tensile strength of the substrate. The tension of the unwinding section should be precisely controlled by a closed-loop tension system to ensure a constant rate of printing material entering the print zone. At the same time, the system must maintain the constant tension in the unwinding area when the machine is shut down, so as to reduce downtime and start printing. District effect.
Printing itself is a multi-parameter dynamic process. As long as one of the factors changes, other factors should be adjusted accordingly to ensure product quality. The adjustment of many factors requires the operator to complete it by hand. This requires the operator to quickly determine which changes are due to product sampling and make appropriate adjustments. Only when these factors are integrated and coordinated can organically be coordinated. Produce high quality prints.
For a flexo printing company, in order to maintain a good competitive edge of the company, it is largely to stabilize the employees of the company, especially the first-line flexo operators, to stabilize product quality.
Brushes with long handles, thin thickness, and short hairs can be used when applying powdered eye shadows, as well as powdered eyeliner and finishing on the upper and lower eyelids.
The order of soft fur is squirrel, goat, horse, nylon.
The eye shadow brush can fully blend the eyeliner with the eye shadow around the eyes and under the eyebrows to create a layered sense of color.
The amount of hair is moderate, which makes it easy to control the amount of powder makeup used. The long handle design has an excellent sense of stability, which can easily show delicate lines and allow the color to spread naturally. Can also be used to shape nose shadows.
The bristles are made of high-tech nylon material or animal hair. It has the elasticity and softness of natural materials, and is naturally bent and formed to achieve ideal powder content and ductility.
