Four Mistakes in the Adaptation of Offset Ink (Brand) In the film production process, it is often necessary to adjust the ink used. To adapt to the printing needs of different products and different papers. The ink is suitably adjusted. This is achieved by adding appropriate auxiliary materials to the ink. Because people have different understandings or prejudice about the auxiliary materials, therefore. In actual production, it is very likely to enter certain "misunderstandings", resulting in unsatisfactory results.
Kids squeaky shoes are also called baby musical shoes, or baby shoes with sounds, it is a popular style as fashion as kids LED shoes and kids shoes with light, and also other funny baby shoes styles.
Most kids squeaky shoes are using soft rubber sole with a squeaky inside, so the shoes would squeaky when babies walking,
The upper materials usually use PU leather, mirror PU with a shining surface, matte PU no-shining, metal PU with metallic finish. All materials in varieties colors.
Moreover, other materials like genuine cow leather, glitter also can be used for shoes upper in different fashion designs.
The common sizes we create for kids squeaky shoes are suitable for toddlers in 1 to 6 years old, US sizes from 4 to 8.
All materials we used for kids squeaky shoes are following the requirement of US CPSIA policy, pass customs test, Pb element no higher than 90ppm, safe for babies and environment.
Kids squeaky shoes, baby musical shoes, baby shoes with sounds, LED shoes, shoes with light... We are trying to add more funny element into baby shoes and kids shoes to make babies happier.

First, completely replace the varnish with a debonding agent
during production. When printing large areas of the field version. The ink is not easily beaten during the transfer process of the ink roller or when the paper is "hair loss" and the print is rough. Generally, the viscosity of the ink is too high.
Detackants and varnishes can reduce the viscosity of the ink, but their properties are not exactly the same. The detackifying agent also has the effect of suppressing the drying of the ink and the property of lowering the adhesion of the ink layer to the paper while reducing the viscosity of the ink. The varnish is used in the ink to reduce the viscosity of the ink and increase the fluidity of the ink. Although it has an effect on the drying speed of the ink layer, it is not obvious. If an excessive amount of detackifying agent is added to the ink to achieve the effect of lowering the viscosity of the ink, it is likely to cause a phenomenon that the "printing is not dry" or the ink layer is "pulverized". Therefore, pay attention to the "quantity" problem when adding debonding agents, and never take it lightly. Keep it within the proper ratio. At the same time increase the amount of desiccant. To avoid the above adverse consequences.
Second, use white ink as a thinner
Individual color inks need to be added with a thinner in the original ink to make it a light-colored ink. Such a thinner should have colorless and transparent properties. Both the gloss paste and the Weili oil are ideal rinsers, which have the effect of changing the original ink hue but changing the depth of the original ink. If white ink is used as a thinner. It is not appropriate. Since the white ink has a white hue, it changes the hue of the original ink so that the original ink tends to be white and jade ink instead of being a light ink. This is contrary to the original intention of the operator to need light ink. And in the offset process. If there are too many white ink components in the ink, the pigment particles may be stacked on the printing plate or the blanket during the ink transport process due to the large ratio of the white ink pigment particles. And cause the flaws of the rough print.
Third, do not distinguish the different roles of anti-adhesive agents and debonding agents
The addition of a release agent to the ink can prevent or reduce the problem of sticking on the back side of the printed paper. However, it is to reduce the viscosity of the ink, which is mainly used in the process of ink transfer during printing. If you confuse the two without distinction, it is likely to create other problems.
If a detacking agent is added to the ink in order to prevent the ink on the back side of the paper from being sticky, the "dry" nature of the detacking agent will prolong the drying time of the ink layer of the printing paper, which is counterproductive to make the surface of the paper more susceptible to sticking.
on the other hand. If more anti-adhesive agent is added in order to reduce the viscosity of the ink during printing, it not only does not function well. It also causes the ink to "roughen". It loses its luster and affects the quality of the product.
Fourth, do not pay attention to the difference between red and white oil
Red dry oil (also known as drilling dry oil) and white dry oil (also known as dry oil) are ink desiccants, but the composition of the two components is different. The dry form of the enamel layer is also different.
The addition of red dry oil to the ink can greatly accelerate the surface of the ink layer by oxidizing the film, that is, drying quickly on the surface of the ink layer. However, the red dry oil does not promote the dry operation speed inside the ink layer. White oil has the property of promoting the overall drying of the ink layer. When the white dry oil is added to the ink, the drying speed of the surface and the inner layer of the ink layer can be greatly improved. therefore. We are using desiccant. Attention must be paid to the difference between the dry forms of the two. E.g. For the drying of the ink layer surface. Red dry oil is superior to white dry oil.
However, if the solid plate or paper with a thick printed ink layer is not good for the drying performance of the ink layer due to the acidity and alkalinity, if the operator simply uses the red dry oil as the ink drying gel, the ink layer may occur. The surface is dry but the interior is not very dry. Such a printed product can easily wipe off the ink layer in the case of external force rubbing, so that the printed matter is left with scratches and affects the quality of the product.
In addition, when a gold ink or a silver ink is printed, it is necessary to add a desiccant. Generally, it should be used with red dry oil instead of white dry oil. Because white dry oil is combined with gold ink and silver ink. It has a tendency to make the original ink color dark. This print will affect the luster effect of gold and silver ink.
