The thermal foaming ink jet technology heats the ink during use, and the ink easily undergoes chemical changes at high temperatures, and the properties are unstable. Therefore, the authenticity of colors played will be affected. On the other hand, since the ink is ejected through the bubbles, the directionality and volume of the ink particles are not well understood, and the edges of the printed lines are variably confusing, which affects the print quality to some extent. Micro Piezo Inkjet technology uses micro voltage to accurately control the size and concentration of the ink droplets so that the droplets do not scatter or spread like a star when they are ejected. The principle of direct voltage conversion is used to realize the normal temperature working state of the inkjet head, and the life of the inkjet head is greatly improved. In addition, pigment-based inks can be easily used to achieve outdoor-oriented applications, and the overall consumption of ink is small; there is great potential in terms of speed. A picture frame is a protective and decorative edging for a picture, such as a painting or photograph. It makes displaying the work safer and easier and both sets the picture apart from its surroundings and aesthetically integrates it with them.

A picture frame is a container that borders the perimeter of a picture, and is used for the protection, display, and visual appreciation of objects and imagery such as photographs, canvas paintings, drawings and prints, posters, mirrors, shadow box memorabilia, and textiles.
Traditionally picture frames have been made of wood, and it remains very popular because wood frames can provide strength, be shaped in a broad range of profiles, and allow a variety of surface treatments. Other materials include metals, e.g. silver, bronze, aluminum, and stiff plastics such as polystyrene.
A frame surface may be of any color or texture. Both genuine gilding and imitation gold remain popular, although many other surfaces are to be found in most framing establishments. Some picture frames have elaborate moldings, which may refer to the subject matter. Intricate decorations are often made of molded, then gilded plaster over a wood base.
Picture frame mouldings come in a wide variety of profiles, generally in some sort of L shape with an upward "lip" and a horizontal rabbet. The rabbet functions as a shelf to hold the frame glazing (if any is to be used), some sort of spacer or mat/matte to keep the object safely behind the inner surface of the glazing, the object itself, and backing boards to protect the object from physical damage and environmental pollutants. The lip extends a proportionate distance up from the edge of the rabbet. It restrains materials in the frame and can be used to help set off or reveal the picture aesthetically.
