What is the Treatment Method of UV Printer with Wrong Ink?

Sep. 27, 2020

If the UV printer accidentally adds ink that is different from the ink cartridge, it is easy to cause the two inks to be incompatible. Make deposits in the ink path, block the ink path system or nozzles, and cause unnecessary losses. As a UV Ink Supplier, share with you. Once the wrong UV ink is added, there are the following four solutions:

One: The UV ink has just been added to the ink cartridge and has not yet entered the ink supply path. In this case, you only need to replace a new ink cartridge.

Two: If the UV ink has entered the ink supply ink path, the entire ink path needs to be cleaned and the corresponding filter must be replaced. If it is not clean, the entire ink supply system needs to be replaced.

Three. If the cleaning function has been turned on, it means that the ink has entered the print head. At this time, you need to remove the print head immediately, clean the print head with cleaning fluid, and discharge the ink as much as possible.

Four. If the nozzle is severely clogged, you need to find a professional to deal with it.

For a new starter in UV printing, a quick introduction to UV ink,

UV ink is a kind of ink without solvent, fast drying speed, good gloss, bright color, water resistance, solvent resistance, and abrasion resistance. UV ink has become a more mature ink technology, and its pollutant emission is almost zero. It should be noted that the water-based UV ink in UV ink is a new research direction in the field of UV ink. Because the viscosity of the prepolymer in ordinary UV inks is generally very large, it needs to be diluted with a reactive diluent. The diluent acrylate compounds used have different degrees of skin irritation and toxicity. Therefore, low viscosity prepolymers and low viscosity In addition to toxic diluents, another development direction is to study water-based UV inks, that is, water and ethanol are used as diluents. Water-based UV inks have been successfully developed and used in some printing companies.

UV ink has the characteristic of selectively absorbing UV light. Drying is affected by the total energy of UV light source radiation and the energy distribution of light of different wavelengths. Under the irradiation of UV light, the UV ink photopolymerization initiator absorbs photons of a certain wavelength and is excited to an excited state to form free radicals or ions. Then through intermolecular energy transfer, the polymerized prepolymer and light-sensitive monomers and polymers become excited states, resulting in a charge-transfer complex. These complex particles are continuously cross-linked and polymerized to solidify into a film.
