In the process of printing with flatbed printers, some professionals will encounter the phenomenon of incomplete curing of UV inks and sticky appearance, which results in unambiguous printing. To solve this problem, you must first understand the uv flatbed How can the printer get good curing of uv ink? Below, the flatbed printer manufacturer tells us the three elements of curing the ink.

1. Spectrum

    Flatbed printers require the use of ink when printing and production, and the curing of the ink is inseparable from the UV curing lamp. If the light emitted by the UV lamp is inconsistent with the absorption spectrum of the cured material in the ink, the curing effect of the UV ink is not It would be very ambitious. On the contrary, if the light emitted by the UV lamp used has the same spectrum as the absorption spectrum of the cured product of the UV ink, it will have a good curing effect.

2. The intensity of light

     If the light source in the flatbed printer is not good enough, the curing effect of the ink is still not very promising. Although light can cause a photochemical reaction to the cured product, there are many brands and models of UV coatings, inks and glues that can be used. Different brands have different internal sensitizer performance and dosage, and the light transmittance of the main agent and the dose agent , Sensitivity is also different, so the curing intensity requirements are different, as long as the intensity of the light source in the flatbed printer meets the curing requirements of the UV ink, the curing can be better.

3. Curing speed

    When using a flatbed printer, if the curing speed is too fast, the curing cannot be completed, and if the curing speed is too slow, it will have an adverse effect on the cured product, such as picture cracking and poor adhesion. Therefore, in order to obtain a good curing effect, it is also necessary to determine when the curing speed is based on the ink used.

    In order to have good printing quality, not only should the flatbed printer be equipped with high-quality inks, but also suitable UV lamps should be selected according to the nature of the oil film, and the intensity of the light and the curing speed should be matched to the needs of the ink. Allow the large flatbed printer to solidify the ink well during printing, so that the printing quality can be guaranteed.
