| I. Introduction Ink composition of the liquid part is | | | | disadvantages of resin, color number directly |
| called binders; solid components of pigment | | | | affects the size of the different pigments of color |
| (pigments or dyes) and various additives. First of | | | | expression. At the same time, pigment wetting |
| all, as the pigment ink resin carrier, the pigment | | | | and dispersing resin full or not, directly affects the |
| powder mixture of solid particles such as linking | | | | uniformity of resin encapsulated pigment, ink itself |
| pigment was uniformly dispersed in which, relying | | | | will affect the hue. |
| on its wetting effect, more easily Grinding | | | | 3, anti-adhesive Anti-adhesive printing ink is an |
| machine Device is processed on the ground to a | | | | important indicator properties. Gravure is a high |
| certain fineness; secondly as a binder resin of the | | | | capacity for the ink, tone reproduction is good, |
| pigment was evenly wrapped and ultimately to | | | | fast printing speed of printing, the use of ink over |
| fixation in the substrate surface, in order to | | | | the ink solvent evaporation drying. Ink through the |
| achieve the purpose of display patterns; also relies | | | | plates and then transferred to the printing |
| on its connection to the role of ink was able to | | | | substrate, the through drying tunnel, when the |
| Print Machine is transferred, delivered to the | | | | organic solvent evaporation drying after winding. |
| substrate film or paper; Finally, in the printed | | | | As we all know, after drying tunnel through the |
| product, the connecting material also plays a | | | | high temperature rolling, the Indian film surface |
| protective film role, and presents the necessary | | | | temperature is generally between 40 ~ 60 , and |
| gloss, and even protective role of the substrate. | | | | because the existence of winding pressure, if their |
| Thus seen as the ink in the ink pigment with a | | | | anti-viscous ink is not good, it will cause serious |
| resin carrier core material is ink, its quality is good | | | | rolling adhesion quality accidents, to ink customers |
| or bad, will directly affect the performance of ink, | | | | irreparable economic losses. |
| because the connection material to a large extent | | | | Ink good and bad anti-adhesive, in addition to the |
| determines the ink stick degrees, sticky, dry, | | | | printing process and after the complete solvent |
| mobility and other properties. To get high-quality | | | | gradient of the volatile, but also directly connected |
| ink, we must re-use of high-quality ink resin. | | | | with the resin film and resin material properties of |
| Second, the performance of the ink resin | | | | related molecules. And good film-forming resin |
| 1, ink adhesion fastness Created between ink and | | | | binder to give a good dry of ink, the solvent |
| substrate adhesion include bond strength (that is, | | | | evaporation and drying thoroughly, the film |
| the force between atoms), the force between | | | | thoroughly, after winding excellent anti-adhesive. |
| molecules (hydrogen bonding and Van De Hua Li), | | | | 4, soluble complex In gravure, the ink is re-soluble |
| the interface electrostatic force and mechanical | | | | ink performance test a key indicator of good or |
| force. The main source of these forces is the ink | | | | bad. Especially in the color ink printing, moderate |
| resin binders and the interaction of the substrate. | | | | complex insoluble, not only can show full color, but |
| Different substrates, the appropriate choice of | | | | also a good network to solve shallow plate block |
| resin binders have become a critical, in general, for | | | | version string overprint color problem. |
| PE, PP and other non-polar substrates, even if the | | | | Printed in color ink, according to the requirements |
| corona Surface Treatment The surface tension | | | | of different colors, printed version of the ink |
| of 38 dyne only about the structure should be | | | | depth of mesh points is different Transfer To the |
| used for non-polar resins such as chlorinated | | | | printing surface of the ink is different, and written |
| polypropylene resin binders; while for PET, PA and | | | | a large pore volume, fill the ink printing process |
| other polar substrate surface, polyurethane resin | | | | more than the amount transferred to the |
| can be used binders. Polyurethane Ink System is | | | | substrate film thickness; pains to depict the pore |
| by adding a small amount of material devoted to | | | | volume is small, filled less ink transferred to the |
| PP, PE adhesion promoting agent, or a small | | | | substrate the thin film. Thus, the formation of the |
| amount of chlorinated polypropylene resin and | | | | substrate bias orderly, colorful images. Poor |
| polyurethane resin can often be resolved with a | | | | complex soluble ink, the printing plate light mesh |
| spell in non-polar substrate adhesion problems | | | | tank in Mexico due in part to the high-speed drum |
| have been able to do a resin binder common | | | | rotation, the residual ink ink tank of the ink can |
| issues and to resolve to chlorinated polypropylene | | | | not easily be re-dissolved, which led to more |
| resin binders can easily arise in toluene Solvent | | | | Indian Point network shallower, eventually leading |
| Residues exceeding the issue, in promoting the | | | | to an accident blocking version. Too good for the |
| green Environmental protection Today, this | | | | resumption of soluble ink, while the |

| Visible, resin binder dispersed in the ink as a | | | | soluble solvent ink printed version, the result string |
| wetting medium also provides the most basic | | | | color ink problem. |
| between ink and substrate adhesion fastness and | | | | 5, storage stability Ink storage over time, appear |
| most important, is the most basic indicator of ink. | | | | in the container upper dilute, viscosity, color and |
| 2, ink color strength Ink pigment is to provide the | | | | concentration are relatively poor; the lower part |
| most basic color material, but as ink display | | | | of thickening, viscosity, color and concentration is |
| attached to the substrate surface to the | | | | relatively good sign. Gravure type printing ink |
| consumers of their color, and paint themselves | | | | viscosity because it is thin and fluid, due to poor |
| often produce more or less color deviation. | | | | pigment dispersion in connection compound; |
| Attributed to the ink, the pigment particles do not | | | | pigment or filler density is too large; in the |
| exist, but scattered among the connection | | | | long-term storage of heavy precipitation prone to |
