B. described production method step (5), (6), (7), (8) mixer to add dark slide when stirring.
C. described production method step (9), in (10), the cooling water temperature of indented form grinder is not higher than 20 DEG C, shorten milling time, can effectively reduce UV ink light application time, control grinding temperature simultaneously and effectively keep the photosensitive activity of UV resin.
D. after described production method step (10) completes, ink barrel to be mixed should add bung, places in darkroom.
Show according to great many of experiments, the diversity of stirring and operation of rolling conditional, ink stability in production process can be produced impact.Speed of agitator, mixing time, whipping temp can affect whether UV resin the double bond quantity of excessively crosslinking and UV resin occurs in whipping process；Condition in the operation of rolling controls, and dispersion effect and ink temperature for pigment can produce material impact.
First, rolling number of times is not The more the better, according to experiments show that, after pigment is distributed to certain fineness, colour saturation will not be improved and produce help, and often disperse once, will put into a large amount of artificial and electric energy.
Then, rolling number of times is crossed that I haven't seen you for ages and is caused that pigment dispersion particle diameter is excessive, directly affects colour saturation (colour saturation can reduce), ink rheology is produced unstable factor simultaneously；Rolling number of times is very few, and to also result in ink temperature too high, improves temperature and is conducive to dispersion, but UV ink needs to control temperature, and excessive temperature can produce cross-linking reaction, and causing that ink is rotten cannot use, and it is unfavorable to preserve for ink.
Showing according to great many of experiments, pigment dispersion particle diameter Maximum constraint is at 12-15 microns, and ink temperature controls to make UV ink performance best about 40-60 degree.For this, We conducted experiment, between controlled rolling roller, pressure is 3-4Mpa, and roller temperature is 30-40 degree, and experimental data is following table such as:

| 1 | 12-15 | 80-100 |
| 2 | 12-15 | 60-80 |
| 3 | 12-15 | 40-60 |
| 4 | 12-15 | 30-40 |
| 5 | 12-15 | 20-30 |
Table 2: with ink temperature for independent variable, pigment dispersion particle diameter is that variable is tested
| Rolling number of times (secondary) | Pigment dispersion particle diameter (micron) | Ink temperature (degree) |
| 1 | 25-35 | 40-60 |
| 2 | 16-25 | 40-60 |
| 3 | 12-15 | 40-60 |
| 4 | 10-12 | 40-60 |
| 5 | 8-10 | 40-60 |
Being shown experimentally that, between rolling roller, pressure is 3-4Mpa, and when roller temperature is 30-40 degree, three times the operation of rolling is best.Three times rollings are for 2 considerations.One, dispersion effect is good, and pigment may be uniformly dispersed in resin system, and pigment dispersion particle diameter Maximum constraint is at 12-15 microns, and centrostigma particle diameter can control below 5 microns, and particle diameter is normal curve distribution and concentrates.Its two, in effective controlled rolling process ink temperature raise problem, ink temperature controls about 40-60 degree.In the present invention, stirring and the operation of rolling in the present step of condition control volume (6)-(11).
