What Do You Need Pay Attention To Eco-solvent Ink In Winter ?
Eco-solvent ink,a type of friendly ink ,used for eco-solvent printing like advertisment printing (outdoor and indoor advertisment printing ).As we all know ,store eco-solvent ink espically in winter is very important .
The recent domestic climate has entered the winter, the temperature decrease led to the gradual entry of all regions into the coldest of the year. Ink in the case of reduced temperature, its physical and chemical parameters will be subject to change and affected by some problems, the specific situation is not the same, but mostly due to the cold climate, caused by dry.
1, the biggest problem facing the winter: low temperature!
When using inks in winter, temperature is one of the major issues. After the temperature is lowered, the viscosity of the ink will increase so that its fluidity deteriorates, so that the printhead nozzle normal out of ink are affected, such as the print screen appears crosswalk (white road) or print frequently broken ink phenomenon, the serious will Resulting in piezoelectric ceramic nozzle fatigue damage.
We recommend using the following methods to deal with this issue:
1) Increase the ambient temperature of the printer by air-conditioning or heating (it is recommended to keep it at least 15 ℃ above);
2) at the secondary ink cartridges and the main barrel at a temperature control device to increase the ink temperature to 25-28 ℃ (recommended large-scale inkjet machine used), this method with larger power but better results are relatively safe;
3) If the printer working environment temperature is below 15 ℃, it is recommended to open the print nozzle heating function, or some nozzles do not have built-in heating function, you can also open the front panel heating function. If the printer has one of the above two heating functions, it is recommended to set the heating temperature at 30-32 ℃;
4) If the printing ink is prone to breakage and flying ink when the viscosity of ink is lower due to the lower ambient temperature, users of inkjet printer may be advised to try to increase the printhead voltage to gradually try to increase the printhead voltage by + 0.2V Get a better print results, please note the inkjet printer nozzle voltage limit, the nozzle drive voltage should be controlled within the maximum limit. If you do not know the nozzle voltage safety limits, please read the printer manual or call the printer manufacturer to understand;
5) If your inkjet machine uses secondary sub ink bottle siphon ink nozzle design, in the face of low temperature ink viscosity increases, you can also try to position the secondary sub ink bottle, so you can also solve Increased viscosity of the ink fluidity and jettability of the problem of deterioration, of course, how many sub-ink bottle upset how much you need to test the actual value of the best value.
2, the second biggest problem facing winter: dry!
Winter temperatures are low, either indoor or air-conditioned heating, indoor relative humidity will dry the air --- dry (humidity less than 30%). Dry environment will also affect the normal use of ink.
Then some people will ask: dry environment in the end what kind of negative impact it?
Here to explain, the first dry environment will produce and accumulate static, high static electricity not only have a greater impact on the printer, the use of ink will also have some impact, such as the emergence of printing ink flying phenomenon. There is a weak solvent inks as the main solvent for the volatile liquid, air drying speed of its volatility, the nozzle surface ink will speed up the dry knot, causing the nozzle hole surface clogging phenomenon in the printing process for the performance of the ink and Frequent disconnection and ink jet skew occurs, if you do not pay attention to timely cleaning nozzle maintenance may also damage the nozzle.
Second, the cold and dry environment can also change the properties of the printed materials, changing the properties of coatings or other chemical materials on some materials to change compatibility with the inks, as well as materials based on photographic materials such as paper A class of materials in the case of dry material occurs Alice edge or over-ink coating and some other issues, if not resolved in time, will result in print quality problems, so we recommend that qualified customers will still print the room temperature / humidity to maintain In the ideal range (18-27 degrees Celsius, 35% -80% relative humidity), also suggested to fight against the power of the printer ground.
3, the importance of transport and storage environment!
Some people think that as long as my room temperature and humidity control well on the ink how to transport and storage does not matter. In actual fact, the ink transport and storage environment is also a key factor affecting the performance of ink use, if the temperature is too low, over time will affect the physical and chemical parameters of ink changes.

Here are some suggestions on our shipping and storage conditions:
1) ink transport in winter, especially in northern China, it is recommended that the transport time at low temperature (minus 10 ℃ or lower) less than a week. If this time is exceeded, it is recommended to use insulated containers or transport vehicles with good insulation and airtight conditions.
2) the ink storage warehouse should have a certain insulation conditions, if you do not have the conditions recommended installation of heating or air conditioning, preferably able to maintain the storage temperature 5-30 ℃, air humidity 25-70%, to ensure the normal ink storage.
3) in the printer cartridge / main tank before the ink runs out, at least 24 hours in advance of the spare ink on the printer. So that when you change the ink, the temperature of the ink in the backup ink and the printer cartridge / main tank is close. (Customers are advised to print materials used in this way)
