A comparison was made in conjunction with a variety of crystallized printed articles currently on the market:
tests show that the grain effect is more stable and natural along with the rise of the temperature of IR baking, and the higher the temperature is, the better the effect is within the range of 130 +/-5 ℃; increasing the IR baking temperature excessively beyond the above range only degrades the quality of grain formation.
To UV printing ink layer, improve the ratio of principal ingredients in the printing ink, under the fashioned prerequisite of crystal grain not influencing for the printing ink layer attenuation makes the crystal grain line more meticulous.
And the two layers of printing ink interact to generate a swelling phenomenon, the coatings extrude and mix with each other along with the rise of temperature to generate an irregular grain effect, and due to the improvement of the components such as 1, 6-hexanediol diacrylate and the like in the formula, when the coatings are independently formed, the coatings have a network hierarchical structure with higher crosslinking degree inside, and are more 'three-dimensional' and clearly layered, and when the coatings extrude with each other, the three-dimensional effect is further enhanced, so that the finally formed grain structure is more distinct in level and full in three-dimensional effect, and the forming effect of the grains is enriched.
Before coating two layers of printing ink, the printing ink base layer is attached to the surface of a printing piece under a proper humidity environment, and is dried and solidified, so that the printing piece is firmly formed; the two layers of ink also react with the ink base layer to adhere to the substrate. Finally, the whole crystal grain is not easy to fall off from the printing piece.
When the two layers of printing ink are solidified, the two layers of printing ink are solidified by specific energy, and the effect of the grain lines is stable.
Tests show that when the screen printing is carried out, the effect that the lines are obviously observed is poor when the screen mesh is less than 100T, and obvious line faults can be caused when the difference value of the screen meshes of the two layers of printing ink is more than 20T.
Therefore, the product prepared by the three-dimensional crystal grain printing process in the embodiment 1-3 has the advantages of more distinct grain structure level, better three-dimensional sense, finer crystal grain grains, better crystal grain effect and the like.
Comparing the crystal grain paper obtained in examples 1 to 3 with the crystal grain products sold on the market (taking the crystal grain paper sold by Shantou Shanyu paper industry Co., Ltd as an example), wherein the basic conditions such as the area size of all the finished product paper, the material of the printing paper and the like are the same, namely only changing relevant step variables in the three-dimensional crystal grain printing process, such as conditions of ink components, curing energy and the like, and obtaining a conclusion after analysis, the table below shows:
TABLE 1
| Detecting items | Example 1 | Example 2 | Example 3 | Common crystal grain paper |
| Visual inspection of grain appearance | Good effect | Good effect | Good effect | General effects |
| 20 degree gloss | 92％ | 89％ | 90％ | 70％ |
| Gloss at 45 degree observation | 79％ | 75％ | 72％ | 43％ |
| 60 degree gloss | 61％ | 55％ | 52％ | 31％ |
| Adhesion condition | Good effect | Good effect | Good effect | In general |
| Wear resistance | Is preferably used | Is preferably used | Is preferably used | In general |
| Film thickness | 7μm | 8μm | 8μm | 12μm |
As can be seen from table 1, the coating films of examples 1 to 3 are much smaller than those of the existing prints, the abrasion resistance and the adhesion ability are stronger than those of the existing prints, and the gloss is better when observed from different angles because of the network hierarchical structure with higher degree of crosslinking, wherein each performance of example 1 is the best, so example 1 is the best scheme among the three examples, and the ink components are the best mixture ratio.
It should be noted that the present embodiment is only for explaining the present invention, and the present invention is not limited thereto, and those skilled in the art can make modifications to the embodiment without inventive contribution as required after reading the present specification, but all the modifications are protected by patent law within the scope of the claims of the present invention.
