Description

Digital transfer decal for manicure and its manufacturing method

technical field

The invention belongs to the technical field of material chemistry, and in particular relates to a digital transfer decal for manicure and a manufacturing method thereof.

Background technique

Decorating nails or false nail patches by means of painting and other methods is a widely used technique in nail art technology. At present, this kind of painting method can be made on-site in the nail shop, and the manicurist can manually paint on the nails or stickers; you can also directly buy ready-made nail stickers printed with painted patterns. The former has a wider range of choices and can DIY design various patterns, but the painting takes a long time, and the final product effect cannot be confirmed until the painting is completed. Therefore, the skill level of the manicurist has a great influence on the makeup effect. big. For the latter, you can choose your favorite painted pattern, and just stick the patch directly to the nail, which is convenient and fast, and the effect of the finished product is predictable. But the selection range of existing nail patch patterns is small, and the creativity is relatively poor.

Using the method of digitally transferring decals, the operation method is simple and fast, and various creativity can be used to make various patterns, texts and even photos on nails or stickers.

The transfer decal technology began in the late 1960s and was first applied to textile printing by means of thermal transfer decals. A printing method that first prints a certain dye on other materials such as paper, and then uses hot pressing to transfer the pattern to the fabric. Subsequently, the transfer decal technology has developed rapidly and is widely used in various fields. The principle of indirect printing and perfect printing effect solve the problem of surface decoration of many products. Transfer decal technology is used in the surface decoration of various automotive supplies, electronic products, household supplies, daily necessities, and interior building materials. In terms of body decoration, tattoo stickers should be the most well-known products using transfer decal technology: wet the back paper of tattoo stickers with clean water, then directly stick the patterned side on the skin, and gently scrape the pattern with nails On the back, finally peel off the backing paper along the skin to separate it from the pattern.

This transfer decal technique can also be applied to nail decals. But considering the health of the nails and the abrasion resistance of the decals, the way of water transfer decals is not suitable. Graphics can be photo-cured to the nail or patch and peeled off from the underlying material.

CN201180063897.7 introduces a method for applying UV glue to nails. First, apply nail decals made of dry nail polish to the nails. The UV glue is then applied on top of the nail decal with a brush and then cured using a UV lamp. In this method, the nail decals are made of dry nail polish, indicating that the pattern still needs to be drawn by hand; and it is difficult to ensure that the decals are completely attached to the nail surface during the UV curing process.

Since the shape of the nail surface is irregular, in order to make the decal fit the nail surface better, the transfer film needs to be made of a material with good ductility. If an ordinary roll-to-roll printer is used to print, the transfer film will be stretched and deformed during the printing process, so a flatbed printing method should be used.

Contents of the invention

The object of the present invention is to provide a digital transfer decal for manicure and a manufacturing method thereof which are simple and fast in operation and can display various creativity.

The method for making digital transfer decals for manicure provided by the present invention is to print arbitrarily designed patterns on the transfer film of a transparent or translucent substrate by means of digital printing, and the surface of the substrate needs to be pretreated; The light curing method transfers the pattern to the nail or nail patch to form the desired decal.

In the present invention, printing the pattern on the transfer film is called the primary transfer of the pattern; the present invention also includes carrying out the secondary transfer of the pattern, and then transferring the pattern to the nail or nail patch to form the required decals. After the pattern is transferred once, the pattern obtained on the nail or nail patch is opposite to the original design pattern; after the pattern is transferred twice, the pattern obtained on the nail or nail patch is consistent with the original design pattern.

In the present invention, the substrate of the transfer film can be selected from polyethylene terephthalate (PET), polyethylene (PE), polypropylene (PP), polyvinyl chloride (PVC), polystyrene (PS), Oriented Polypropylene (OPP), Polyvinylidene Chloride (PVDC), Ethylene Vinyl Acetate (EVA), Polyurethane (PU).

In the present invention, the pretreatment on the surface of the substrate is to pre-coat a coating on the surface of the substrate, the coating can inkjet print decal patterns, and the decal patterns and coating can be removed from peel off the substrate. The coating material can be butyl cellulose acetate.

The decal pattern on the transfer film can be printed with conventional printer ink. When using flatbed printing, the transfer film is fixed on the flatbed during the printing process, and the printer moves to print the set decal pattern on the film.

When the decal is transferred to the nail or the patch, firstly apply a layer of light-curable nail polish on the nail or the patch, then stick the side of the transfer film with the decal pattern on the nail or the patch, and tear it off after curing with light. Apply the transfer film and the decal stays on the nail or patch.

The nail polish can be a visible light curable nail polish, and the transfer decal process adopts a visible light device or sunlight for curing.

The nail polish can be UV-curable nail polish, and the process of transferring decals is cured by ultraviolet lamps or devices.

The invention solves the problem that ordinary flexible substrates cannot be printed by inkjet by adding a transfer film on the flexible substrate, and makes large-scale application of digital transfer decals for manicure possible.

Detailed ways

Below in conjunction with embodiment, the present invention is described further. The described embodiments are only some of the embodiments of the invention. All other embodiments without creative achievements based on the embodiments of the present invention belong to the protection scope of the present invention.

Embodiment 1 (transfer decal once)

In the digital transfer decal for manicure provided by the present invention, the desired decal pattern on the ten-finger nails is pre-set in the printing software, and then printed on the transfer film. The transfer film is a PET film with a pretreatment coating on the surface, which is fixed on a flat plate, and the printer moves along the surface of the flat plate to print the set pattern on the film. Then the film is cut according to the pattern of each finger nail decal, and the decals are transferred respectively.

In the process of transferring decals, first apply a layer of transparent visible light curing nail polish on the surface of the nails, and then accurately attach the side of the film with the decals to the nails. Then put the nails in the visible light curing manicure machine and irradiate them for about 1 minute. After the nail polish is dry, tear off the transfer film to complete the decals on the nails.

In the digital transfer decal for manicure of the present invention, the inner side of the decal pattern and the nail are bonded with nail polish, so that the ink of the printed pattern does not directly contact the nail, so there is no need to worry about causing health problems. The bonding of light-cured nail polish is stronger, and the decals are not easy to fall off. Moreover, the light-cured nail polish has a high gloss, so the nails are more shiny. In addition, the nail polish can also fill up the texture on the nails, so there is no need to smooth the nails before applying the decals, avoiding damage to the nails, and the bonding fastness is also higher.

Using visible light curing nail polish, you only need to use high-concentration salt water or soda water to remove the decals. You don't need to wear your nails, and you won't be exposed to harmful chemicals that will affect your health.

Embodiment 2 (secondary transfer decals)

In the digital transfer decal for manicure provided by the present invention, the required decal pattern on the ten-finger nails is pre-set in the printing software, and then printed on the primary transfer film. The primary transfer film is a PET film with a pretreatment coating on the surface, which is fixed on a flat plate, and the printer moves along the surface of the flat plate to print the set pattern on the film. Then the film is cut according to the pattern of each finger nail decal, and the decals are transferred respectively.

The process of transferring decals is divided into two steps:

First, transfer the decal graphic onto a secondary transfer film. Coat a layer of transparent visible light curing nail polish on the secondary transfer film, attach the decal pattern to the nail polish of the secondary transfer film, and then put the film into a visible light curing nail machine for irradiation. After the nail polish dries, the primary transfer film is torn off, and the decal pattern remains on the secondary transfer film.

The decals are then transferred to the nails. Apply transparent visible light curing nail polish on the nail surface, and then accurately fit the decal pattern on the secondary transfer film to the nail. Put the nails in the visible light curing nail art machine and irradiate them. After the nail polish dries, tear off the secondary transfer film to complete the decals on the nails.

The use of secondary transfer decals has the following advantages over primary transfer decals:

(1) After the secondary transfer, the decal pattern on the nail or patch is the same as the printed pattern. After a decal is transferred, the decal pattern and the printed pattern are reversed, so the character patterns such as words and numbers need to be designed in reverse when printing, which brings inconvenience. The pattern of the secondary transfer is the same, avoiding the above-mentioned problems;

(2) After the second transfer, the decal pattern is covered between two layers of light-curing nail polish, so the protection is better. The inner side of the decal pattern and the nail are bonded with nail polish, which is more firm, and the ink of the printed pattern does not directly contact the nail, which will not cause health hazards. There is also a layer of light-cured nail polish on the outside of the decal pattern as a protective layer, which has better surface properties, wear resistance, water resistance, and oil resistance, so the decals are more durable.
