UV Printing Process On The Application Of Electronic Atomization Housing
The technology of UV printing is robust and constantly evolving. Electronic cigarettes, as a consumer electronics product, have always been aesthetically pleasing. E-cigarettes can be made to look different using a range of techniques, including gradient anodizing, two-color injection molding, skin, stickers, spray painting, screen printing, and more.
1. Overview of the UV printing method and its fundamentals
“UV” stands for ultraviolet radiation, and “UV flat printing” refers to UV curing printing. UV light drying and curing ink printing are processes that need the presence of photosensitizer ink and a UV curing lamp match. UV printing is essentially a type of piezoelectric inkjet printing.
The drying concept of UV printing is that the pigment molecules in the UV ink cure on the material surface as a result of a reaction between the UV wave emitted by the LED cold light source lamp and the photosensitive curing agent in the UV ink. This completes the printing activity.
2. The UV printing method
There are two primary procedures:
A, based on the label’s layout and content printing UV ink design
While UV varnish can also be coated on the substrate, its viscosity is much lower than that of ink, so the substrate surface must be dense in order for the varnish to not penetrate the oil. UV printing is itself a printing process; letterpress, gravure, and lithography are sufficient to print ink on the substrate.
B. UV ink drying and curing
UV ink is sprayed over the substrate; typically, the ink is just 3–5μm thick, which is extremely thin, and is allowed to settle into the ultraviolet radiation area to cure over time. The unsaturated carbon-carbon double bond (liquid) in the prepolymer and monomer withstands the energy imparted by the light initiator and each other crosslinking to form a network structure (homomeric) during the curing phase, which is a chemical crosslinking process. On the other hand, curing differs depending on UV oil thickness, time, and UV radiation intensity. UV oil thickness and radiation energy transmission have an exponentially declining relationship.
C, printing the AB film scheme
Print on the A film first using the UV flatbed printer, and then use the laminator to fuse the B film to the A film. Ultimately, the AB film can be attached to the substrate by slicing it into small pieces in accordance with the design concept.
Alternatively, print a film on a UV roll-to-roll printer first. Then, the device will automatically laminate, saving you the trouble of operating the laminator by hand. Paste on a variety of substrates for final cutting by machine or by hand.
Similar to the electronic cigarettes discussed in this article, there are several ways to create the desired appearance. You can utilize spray printing, AB film transfer, or direct UV flat print to achieve the desired result. Vibrant hue, resilience to wear and tear, resistance to scratches, and other benefits.
3. Characteristics of the UV printing process:
(1) May give the print a smooth, three-dimensional appearance, significantly enhancing its visual appeal.
(2) Make printed materials brighter, shield their surfaces from damage, and provide them resistance to rust, abrasion, and scratches.
(3) There is less wasted ink usage with UV printing as opposed to conventional four-color process printing.
(4) Some laminated printed materials are subjected to the UV process, which can raise the material’s safety factor and enable it to comply with environmental protection regulations.
(5) The selection of printing materials is extensive; in addition to standard printing paper, one can use cellophane, plastic film, and aluminum foil composite paper.
(6) There are no material restrictions when it comes to UV flat printing application; color photo grade printing may be done on glass, plates, crystals, PVC, acrylic, metal, plastic, stone, leather, etc. without the need to make plates; printing is done after just one printing. SUBLISTAR has led the way in the current research development of UV use in garments. Additionally, create an application video presentation that most customers would be eager to view.
4. UV versus conventional printing
The UV printer differs from the traditional inkjet printer in that it uses UV ink and a UV lamp to speed up the ink formation process by using the ingredients in the ink to cross-link polymerization under a specific wavelength of ultraviolet light. It also solves the issue of white ink not being used with color ink, creating a distinctive artistic style.
The UV flatbed printer is one of the types of digital printing machines that can be controlled by a computer. Through software processing and typesetting, it can print packaging boxes directly without the need for plates. Its fast efficiency, bright color, high firmness, and one-person operation make it suitable for both small batch customization and mass production.
The difference between UV printing and traditional printing:
Overall, UV flat printing has many uses outside of just the shells of electronic cigarettes. Its color is rich and beautiful, it resists wear and tear, provides UV protection, is easy to use and convenient, and prints images quickly enough to meet industrial printing standards.
