Ink jet printing technology environmental protection have been questioned

Inkjet printing has been widely applied in the field of various shapes and all kinds of material of the surface of the packaging printing, whether it is with hole or without hole, flat or curved surface, surface fabric or with bones and muscles form, such as plastic, cloth, paper, fur, such as ceramic, glass or metal.
Unparalleled advantages ink-jet printing is with the continuous development of the computer control technology and packaging technology developed rapidly, now in many modern factories and packaging applications to automatic line.
Inkjet printing has other way incomparable advantages, such as intelligent wide adaptability, high speed, low cost, no pollution, etc.
The operator can easily and quickly on the spot (
Movement)
Date printed on the packing materials, specifications, warranty, number, bar code, etc.
Inkjet printing products after the quick drying, can immediately into the next procedure.
Different from the traditional packaging and printing, inkjet printing is no longer needed plate-making and special before printing auxiliary process.
Advanced ink-jet printing system, only the operator press the keyboard when operating, you can change to print, sign, and various graphic, not only can be used for printing words and Numbers, also can choose extension bar code and user implementation (
Customers)
Anti-fake mark spray printing function.
Inkjet printing system has been far beyond the scope of traditional printing and it not only have the functions of black and white and color printing, also have the function of data processing and information storage.
It analyzes the (
Installation)
Memory storage that can store hundreds of independent encoding (
Digital or character sets, etc. )
And nearly all characters.
It is connected to the computer, can realize work record and report the finishing and printing.
When it is in series with the master, but also on the packaging (
Or other pieces of the printing)
Spray print weight, satellite communication coming from a variety of data records, rendering atmosphere cloud, etc.
Inkjet printing has been widely applied in the field of various shapes and all kinds of material of the surface of the packaging printing, whether it is with hole or without hole, flat or curved surface, surface fabric or with bones and muscles form, such as plastic, cloth, paper, fur, such as ceramic, glass or metal.
At the same time are suitable for all kinds of printing speed, uniform speed, variable speed or intermittent operation, and is suitable for continuous not pause on the packaging production line of work.
In continuous production line for ink-jet printing number, date, etc. , than the other printing adhesive labels or more economic and efficient.
Principles consistent with the inkjet printer ink-jet printing whether it is used in the field of packaging inkjet printing, or used in the field of office inkjet printing, the basic principle is consistent.
In office inkjet printer, for example, introduce the principle of ink-jet printing.
Now in the market there are two main types of ink jet printers: piezoelectric and bubble.
Piezoelectric inkjet printer ink storehouse is at the end of the nozzle, the other end is a piezoelectric material (
Mostly lead;
Aluminum;
Titanium piezoelectric crystal)
And the ink in piezoelectric crystal deformation under the action of high pressure nozzle, drops out by the cartridge after add ink in a timely manner.
Bubble inkjet printers are equipped with thermal resistance near the nozzle, the digital signal of current pulse instantaneous heat (
Heating speed can reach 100 ℃ / s, the temperature can reach 280 ℃)
, to fast local heating of the ink, make the surrounding a bubble boiling a small amount of ink.
In the bubble under the action of high pressure drops by jet nozzle, bubble disappear and take away the heat at the same time.
Ink by storage room quickly add by capillary action.
The principle of the development of ink-jet printing ink jet ink determines the inkjet ink to has some special properties.
First of all, the ink will have certain physical and chemical properties such as viscosity, surface tension, pH value.
Second, the long-term storage stability of the ink should have good performance of continuous and intermittent printing, good color, brightness, purity, and color saturation and water resistance, light resistance, weathering resistance.
Moreover, the composition of the ink cannot react with nozzle, lest cause nozzle clogging;
Clear ink to printing, fast drying speed, but not in the process of injection or when not in use volatile too fast;
Ink to print out the image and text should be neat, no diffusion, lack of ink, unequal phenomenon.
Above in order to meet the performance requirements of inkjet ink, inkjet ink, usually by the solvent, colorant, surfactant, moisturizing factor, pH regulator and other additives.
