Anyone who has bought or been in contact with a bottle printer should know that the bottle printer is ready to dry and benefit from UV light.In this article,Dacen editor will talk about the elements of UV light curing for cylinder printers.
One,the elements of UV curing for cylinder printers
1,curing speed
The curing speed is too fast to 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.
2,spectrum
means whether the light emitted by the light source such as UV lamp is consistent with the absorption spectrum of the cured product.
3,intensity
That is,whether the light emitted by the 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 light transmittance and sensibility of the main agent and the dosage agent are also different.Different,so the curing strength requirements are different.
4.Printing speed is too fast
The fast printing speed of the cylinder printer is also the reason for the incomplete curing of the UV ink and the sticky surface.At this time,the printing speed can be reduced or the light source power can be increased.
