Eyewear printing process

Now the most popular glasses include acetate eyewear, metal glasses, titanium frames and buffalo horn eyewear. On the surface of the glasses, we can see some words, some are the guest's logo, some are the style number, or the advertising language. How are these words or patterns made on the glasses?What is the printing process of glasses?Eyewear manufacturer Bestsea tell you the eyewear printing process.

The most common glasses printing processes are as follows:

1. transfer-print is one of the most common glasses printing processes. The approximate process is: engraving the steel plate (corrosion of pictures and texts on the steel plate through a specific process), fix the steel plate on the pad printer, make the glasses positioning mold, put in the prepared pad printing oil, Put in the glasses and start the machine, and print good to dry.

2. Hot stamping is one of the more commonly used printing processes for acetate frames. The approximate process is: engraving the hot stamping die (just like engraving a seal), and the machine puts the hot stamping aluminum thin paper of the required color (the most common ones are gold and silver), put the glasses in, start the machine, and glue the hot stamping paper on the surface of the glasses through a certain pressure and temperature (usually the inner side of the temple, hot stamping on the lens is also common).

3. Laser. It is one of the common glasses printing processes. It uses the laser beam of the laser machine to leave a designed graphic on the surface of the glasses frames to achieve the desired effect.

(1) Shallow laser. Refers to a layer of shallow traces of graphics and text on the surface of the frame, generally without any follow-up processing. For example, laser customer's trademark, model name, glasses 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, the desired paint color can be dripped on the inside to achieve the desired effect.

(3) Metal frame 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 golden 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 deeper, so as not to see the traces of the laser after electroplating. After the laser, lightly polish and roll in the tumbling box, remove dust coke inside and around the laser groove, and then remove it for electroplating. (This method is suitable for relatively thick line graphics and text effects, and if there is no color oil on it, it's not clearer than shallow radium).

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 glasses frame. This method looks relatively high-end, but the cost is relatively high, not suitable for relatively small graphics.

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

6. UV stickers. Usually used in acetate frames, injection frames, TR90 spectacle frames. The graphics and text are made into thin metal sheets through processes such as corrosion, and glue is evenly coated on the back. 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 after the post is applied, and then polished together with the glasses frame to make it look like the other parts of the glasses. 

7. Crystal glue word. Usually used on acetate frames. Carve or laser a certain depth of pattern or font on the acetate frame, and then apply crystal glue (usually with color), dry it, and smooth it with a water mill. Generally applicable to patterns or fonts with relatively thick lines.

8. 3D printing process. Refers to using a 3D printer to print graphic information on the surface of the glasses. This is a relatively new method. 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 glasses, it will not be described in detail here.
