   If the curing effect of the UV flatbed printer is good, the service life will be longer. This article will talk about what to do if the curing effect of the UV flatbed printer is not good?


   1. What should I do if the curing effect of UV flatbed printer is not good?


  UV printer uv light curing has three elements:


  1. Spectrum, that is, whether the light emitted by the light source such as UV flatbed printer UV lamp is consistent with the absorption spectrum of the cured product.


2. Intensity, that is, whether the light emitted by the UV flatbed printer light source is sufficient to cause a photochemical reaction of the cured product. Due to the performance and dosage of the sensitizer inside the cured product (UV coating, ink, glue), the main agent and the amount of The light transmittance and feel are also different, so the curing strength requirements are different.


  3, the curing speed, too fast curing speed can not complete the curing, and too slow will have an adverse effect on the cured product. Such as pattern cracking, poor adhesion, etc. The curing speed varies with different cured products.

The UV lamp tube of UV flatbed printer mainly refers to the lamp tube that can emit ultraviolet light. When it emits light, it is accompanied by high heat, because it not only excites ultraviolet light, but also accompanied by infrared emission. The light wavelength is concentrated around 365mm. The ratio is different due to the content of different quality lamps. Normal domestic UV lamps have a longer ultraviolet of about 30%, while imported UV lamps have 40-50% content. At the same time, the heat generation is also long and the service life is long, up to 2000 hours. The lamp only lasts about 1000 hours.


In the printing and production process of UV printer, personnel in some industries often encounter the phenomenon that UV inks are not cured and the surface is sticky, resulting in unsatisfactory printing results. This article is "What should I do if the curing effect of UV flatbed printers is not good?" I hope to help you.
