However, the emerging technology is the refractive Screen Printing[Printing?:printing cutting finishing solution] Screen Printing Packaging[Packaging?:DCP-H series packaging sample cutter plotter] family of a star. Refractive traditional network printing technology with the general effect is to make the texture of the zinc version of refraction, or with rotary letterpress printing machine Flat round pressure on gold, silver card paper[paper?:paper sample maker cutting machine], press out the different angles of the lines, resulting in refractive texture , this approach is that the high cost of the plate, the effect is not very satisfactory. The screen printing can easily mirror gold, silver card paper printing out the fine concave and convex lines, irradiated by the light refraction effect will produce colorful, so that screen printing is more noble and beautiful packaging.
Refractive Screen Printing Technology process: Stretching refractive original design → → → clean coarse screen version of the light-sensitive adhesive coating exposed → → → Revised Edition → Developing → printing double exposures.
1) Refractive original design of Screen Printing Technology
Refractive original design elements are as follows: the images need to be dropped out of the parts of the refractive point plotted mm decile chart, the length per mm ~ 8 equal portions into 5 lines, each line is divided into equal portions of 10 to 16 black and white, etc. points, to 16, for example, can be designed into black and 4 white 12, white or black 8 8. The line points straight, circular, elliptical 3, line and arc connected with the image changes to kiss each other.
The appearance of fine refraction patterns, complex, with the naked eye can not see through its internal structure. More than 40 times under a microscope, you can glance to see that the refractive map, or dozens of paragraphs by paragraphs, but the point equidistant arrangement, consisting of lines of different curvature. Refraction line thickness should be 0.10 ~ 0.15μm, used a high-resolution laser imagesetter film[film?:film cutting machine].

2)Making refractive Screen
A) Mesh selection and stretching. Screen production of refraction must be the appropriate choice of wire mesh, wire mesh has good flexibility required, and the rubbing, stretching rate should be very small, mesh should be large, the printing ink layer should be thick. Polyester mesh is an ideal choice, the general choice for the 390 mesh ~ 420 mesh / inch.
Stretching the selection of the oblique angle of 22.5 ° Stretching way, require the tension in the screen
18 ~ 22N/cm. A good stretch for the new screen version of the washing must be rough treatment, which is very important to screen the impact of quality.
B) sensitive adhesive coating. Either automatic or manual glue on glue approach must be to ensure uniform coating formation. Online edition of refraction depends on the number of light-sensitive adhesive glue the thin consistency, are generally takes 4 times. 1st time on the plastic[plastic?:Plastic sample cutting machine] on plastic devices to both sides of the screen scraping repeatedly even move, so sensitive adhesive evenly fill the mesh, and then at 40 ℃ in the dry box dry. 2, 3 glue drying only the surface can be printed, 4th in dry scraping the surface of plastic.
C) exposure. Comparison of refraction lines fine, numerous and dense. To ensure the quality of printing down to be with a vacuum suction device with Shai Banji printing down. When printing down photosensitive film with the screen tightly membrane, copy of time should be appropriate, too long, the developing difficulties will affect the screen is too short anti-Indian forces, refraction lines will be thicker. Test strip can be accurately measured exposure time required.
D) imaging. Screen proofing and good will into the shade of the pool, the pool depth of 20 ~ 30cm, screen should be soaked in water for 1 minute, after repeated pressure to the water screen, the use of pressure sensitive adhesive portion of the image squeeze pressed out, and clean water. In order to ensure uniform refractive screen photographic film, developing low-pressure water gun when washing required. Develop fully and then for drying.
E) Revised Edition. Check the layout without pinholes, bubbles and other defects and repair.
F) second exposure. Screen even after drying a second exposure, the layout of the photographic film completely cured, improved network version of the anti-Indian forces

3)UV refractive ink
Refractive index only in the mirror UV printing inks on the printing surface of the refractive index can produce a unique effect. Printing may add an appropriate amount of diluent required to dilute.
4)Refractive Screen Printing
If the refractive index larger graphic printing, in order to ensure quality, we must use high-precision screen printing to complete, a small area can be taken to hand-printing. Refractive screen printing requires the operator of the production of high-quality screen, squeegee hardness, angle and pressure, and the performance of UV inks and other refractive must understand in order to be able for the production of various problems arising in the course take the appropriate Countermeasures

Notes
A) Different manufacturers of the same type of screen printing ink, its quality and performance are also some differences, usually through a trial first printed, after determining stable and reliable quality for mass production.
B)Ink must be fully mixed before use, especially in the several patterns of ink mixed with Ice, it is best to use bamboo mix, a lot of use of the best mixer mixing with broad leaves.
C) Note Check the ink curing conditions, curing is not complete so as not to affect the hardness and adhesion to ink.
D)Temperature change will change the viscosity of the ink, resulting in differences in the printing effects, it should be ahead of the ink into the printing shop, to adapt them to the room temperature to ensure the quality and stability.
E) UV ink on the skin stimulation, access to be careful to avoid skin contact, such as skin sticky stained with ink, rinse immediately with soap and water.
F) Ink should be at low temperature (2 ~ 18 ℃) under sealed, dark to avoid the heat, shelf life is generally 6 months, so as not to change the ink performance
