What are the eyewear printing process?

On the eyewear, we can all see some text or pattern, some of which are the costumer's LOGO, or the style number, or the slogan. How are these words or patterns made on the eyewear? Nowadays, the more popular eyewear include acetate glasses, metal glasses, titanium glasses and buffalo horn glasses, etc. Different types of eyewear have certain differences in the printing process. In this article, let's take a look at the eyewear printing.

The most common craft of eyewear printing are transfer-print, UV sticker,metal logo, laser and 3D printing.

Eyewear printing 1:transfer-print. It is one of the most common printing processes for eyewear frames. The approximate process is: engraving the steel plate (corrosion of pictures and texts on the steel plate through a certain process), fixing the steel plate on the pad printing machine, making the frames positioning mold, putting in the prepared pad printing oil, and then putting the glasses in to start the machine, printing Good to dry.

The advantages of transfer-print are Rich colors, Small text can be printed, and because the rubber head is rubber, it can print on slightly irregular surfaces, such as round or small waves. In addition, the cost of pad printing is relatively low.

The disadvantage is that the adhesion is average (generally it needs to be hardened, and after drying, a certain amount of strength cannot be covered with nails).

Eyewear printing 2: Hot stamping. It is one of the more commonly used processes for acetate sunglasses and acetate optical. The approximate process is: engraving the hot stamping die (just like a stamp), and the machine puts the hot stamping aluminum thin paper of the desired color (the most common ones are gold, silver, but also hot gun color, red, etc., but they are rarely used ), put in the glasses, start the machine to glue the hot stamping paper on the surface of the eyewear through a certain pressure and temperature (usually the inner side of the spleen, hot stamping on the lens is also common).

The main advantage of hot stamping is that the hot stamping characters have a metallic texture, which is high-end feeling.

The disadvantage is that the color is relatively single, generally only gold and silver, the hot stamping characters should not be too small, and at the same time, it can only be hot stamped on flat or slightly curved surfaces.

Hot stamping method: 1) Concave mold. The hot stamped graphic is slightly concave, which is the most common; 2) Punch. The hot-stamped characters are slightly raised, showing more texture.

Eyewear printing 3:Laser. It uses the laser beam of a laser machine to leave a designed graphic on the surface of the eyewear frames to achieve the desired effect. Commonly used in eyewear of various materials, such as acetate eyewear, metal eyewear, titanium eyewear, horn eyewear, etc.

The common laser forms are as follows:

(1) Shallow laser. Refers to a layer of shallow traces of graphics and text on the surface of the frame, generally without any subsequent processing. For example, laser customer's trademark, model name, eyewear size and other information.

(2) Deep laser. Refers to a layer of radium on the surface of the frame with a certain depth of graphic traces, generally at least 0.3mm or more. After the radium is finished, you can drop the desired paint color inside to achieve the desired effect.

(3) Metal eyewear laser, one is a light laser after electroplating, the radium drops a layer of color on the surface to reveal the background color, for example, a gold frame (the background color is silver), after the radium drops a layer of gold on the surface, the silver is exposed ( The advantage of this method is that the font is clear, but the disadvantage is that it damages the electroplating surface and is easy to oxidize over time). The other is the laser before electroplating. Generally, the radium is slightly darker, so that no traces of the laser can be seen after electroplating. After the laser, lightly polish and roll the tungsten, remove the beryllium front and coke in and around the laser tank, and then remove the electroplating (This method is suitable for relatively thick line graphics and text effects, and if there is no color oil on it, there is no light laser clear).

Eyewear printing 4: Metal Logo. Refers to the production of LOGO by wire cutting, oil pressure, casting, corrosion, etc., after welding, polishing, electroplating, etc., and then installing on the spectacle frame. This method looks relatively high-end, but the cost is relatively high, and it is not suitable for relatively small graphics.

Eyewear printing 5: Crystal sticker. Usually used in acetate eyewear, TR90 eyewear. Make pictures and texts on thin metal sheets through processes such as corrosion. The main process is: carve the slots on the frame, put the metal pieces, drop crystal glue, dry and polish with a water mill, and then enter the regular production process of glasses (such as rolling, polishing, etc.) . The advantage of the crystal wafer is simple operation and relatively cheap cost, but the disadvantage is that it will burst easily over time.

UV stickers. Usually used in acetate eyewear, injection frames and TR90 eyewear. Make pictures and texts on thin metal sheets through processes such as corrosion, and coat the back with glue evenly. The main process is: post on the surface of the glasses. Under normal circumstances, in order to be firmer, a thin layer of transparent paint will be sprayed on the surface, and then polished together with the glasses frame to make it look like the other parts of the glasses. One. The advantage of the UV film is that it looks more metallic and firmer. The disadvantage is that the UV film is easy to be skewed, and it is difficult to rework once it is skewed. In addition, the final cost is higher than that of the crystal.

Eyewear printing 6: Crystal words. Usually used on acetate eyewear. The method is to engrave or laser a certain depth of pattern or font on the acetate frames, then apply crystal glue (usually with color), dry it and polish it with a water mill. Generally applicable to patterns or fonts with thicker lines.

Eyewear printing 7: 3D printing process. Refers to using a 3D printer to print graphics and text information on the surface of the glasses. This is a relatively new way. The advantage is that the effect is more individual. The disadvantage is that the color is relatively monotonous, the adhesion is average, and it is easy to fall off after a long time. Because this method is rarely used temporarily on eyewear, it will not be described in detail here.

The above is the common printing process of eyewear frames. What kind of printing process is suitable for a pair of eyeframes, firstly depends on the material of the eyewear, which technology is suitable for it, and secondly depends on the requirements, that is, what kind of effect you want, because the surface effect of each technology is different. The advantages and disadvantages are also different, it depends on your choice. Only by choosing the most suitable craftsmanship can the eyeframes appear more high-end and the brand sense is stronger.
