UV Flatbed will produce some peculiar smell in actual printing. The worse the ink, the stronger the taste. If a salesperson says that UV ink does not produce peculiar smell, this is impossible. The difference lies in the intensity of the smell and the degree of harm to the surrounding. Today, we will introduce the causes of peculiar smell in printing to friends.

reason 1: the LED ultraviolet light curing lamp of UV tablet will produce slight ozone during irradiation. The taste is relatively light and the amount is small, so it can't be smelled generally.

reason 2: the substrates of different materials are affected by the environment, which will crack out relevant chemicals and produce pungent smell.

reason 3: the UV ink product of UV tablet machine contains certain smell and will produce some smell after curing, or it will react with the substrate itself to produce peculiar smell.

reason 4: some users will add some auxiliaries and other auxiliary materials to the actual printing of UV tablet machine according to the requirements of their own products, which may cause pungent smell, it is worth noting that the odor itself volatilizes quickly and will not stay on the surface of the substrate for a long time. The actual operator only needs to keep more than 2m away from the printing platform of the UV machine to avoid the stimulation of ink odor.

1. Safety first. When storing ink, try to stay away from fire and heat sources to prevent accidents.

 2. It's better to keep a constant temperature in the ink warehouse, which should not be too different from the temperature in the printing workshop. If the temperature difference between the two is large, the ink should be put into the printing workshop in advance, which is not only conducive to the stability of ink performance, but also ensure the high efficiency of production .

3. In some areas in the north, it is cold in winter, so we should avoid storing the ink outdoors to prevent the ink from gelling at low temperature. If gelling occurs, transfer it to the warehouse with high temperature or put it into hot water to restore the insoluble matter to its original state.

 4. The principle of "first in, first out" should be followed in ink storage and management, that is, the ink purchased first should be used first, so as to prevent the ink from affecting its use effect due to long storage time.

5. Ink also has a certain shelf life. If it is stored too long, various components in the ink will separate and precipitate. Therefore, the ink should not be stored for a long time, and the general storage period is 1 year.

6. After printing, the remaining ink must be sealed and stored in the dark. Before reuse, it must be filtered with a filter screen of more than 100 mesh, fully stirred and then mixed with new ink.

Reason: 

 in order to facilitate the user's typesetting, the image can be placed anywhere in the canvas. During printing, the software will automatically lock the image boundary and print from the place with the image.

 solution:  

users can set in "canvas" - & gt; Set the actual printing position on the canvas by "leaving the edge blank when outputting the canvas". Through the above methods, we can solve the problem that UV printer pictures are printed in the middle of the canvas but on the edge.

Reason: 

1. The image exceeds the canvas.

2. Error caused by nozzle aging.

solution: 

1. Rearrange the layout or increase the canvas width.

2. Make up the error.

 through the above methods, the problem of incorrect image output size of UV printer can be solved.

Reason: 

 1. The curve does not match the material.

 2. No corresponding curve is selected.

 3. The output color sequence is incorrect.

solution: 

1. Redo the curve.

2. Select the corresponding curve.

3. Replace the output color sequence.

 the above methods can solve the problem of wrong color printed by UV printer.

Digital printing  the printing ink is directly sprayed on cloth or transfer paper through the principle of digital inkjet. Because of its fast reaction speed, there is no need to make plate; Low proofing cost and good effect; The advantages of wide application range are gradually replacing the traditional screen printing such as flat screen and round screen active ink  ink is named according to its most suitable fabric type! Reactive ink is one of the most suitable and commonly used dye inks for pure cotton, hemp and viscose, which is characterized by bright color and high color fastness; Its coloring principle is an ink combined with covalent bond after chemical reaction between active ink and fiber molecules  it should be noted that the UV ink used in UV printer is not suitable for printing patterns on cotton, hemp and other textile materials. Special textile ink should be used.

 1. The socket of UV flat-panel printer nozzle cannot be touched by hand to prevent oxidation.

 2. During installation, the nozzle socket must be aligned without hard insertion. If the pinhole is broken and the contact is not good, the nozzle will not work normally.

3. Ink and cleaning fluid cannot enter the nozzle socket, and the contaminated socket can be cleaned with alcohol.

 4. When the nozzle is used, a good heat dissipation environment must be maintained, otherwise the nozzle circuit is easy to be damaged. 

5. Electrostatic damage to the circuit part of the nozzle is very serious. When operating the nozzle or contacting the nozzle plug-in board, the operator must eliminate the electrostatic factor.

 6. If the nozzle is disconnected during printing, the spraying must be suspended for suction. If the nozzle is seriously blocked, the nozzle can be cleaned with cleaning solution, and then the ink can be sucked out. Note: the nozzle with serious blockage will cause color difference after cleaning.

 7. Using the function of spray and cleaning strip provided by the printing program can ensure that the nozzles of all colors can spray ink normally during printing. 8. After printing, move the nozzle to the original point and moisturize it.

 9. In the external environment, the indoor temperature is required to be between 15 ° - 35 ° and the humidity is required to be between 30% - 60%.

1. It can print patterns directly on all kinds of materials, and has a wide range of compatibility. 

2. No need for plate making, no need for film color registration, computer control, can print patterns directly. 

3. Led ultraviolet light curing is adopted, and the pattern can be dried and solidified in 3 seconds, which can be printed and taken immediately, so as to meet the needs of fast production of finished products. 

4. Full color image, completed at one time, progressive color to achieve the effect of photo quality, accurate positioning, and the scrap rate is basically zero. 

5. With the white ink stacking function, the 3D relief effect of printed pattern can be realized.

2. On the dark material, it will be very clear to print the color pattern after spreading white.
