problem with UV coating on a digital printer

[RafalWM]

I had some problems with coating SRA3 sheets from a digital press. The areas where there was more ink were ok, but the rest "soaked in". Do you guys have techniques of getting the whole area evenly done? It was on Xerox Colotech paper. Could the paper be an issue or maybe it's a matter of using a different UV coating machine? It works fine on our offset jobs, but digital printing work is fairly new to us.

What machine do you have. We have a Xerox 700 and UV won't dry well on any sheets (scratched off) and Lamination peels of unless it's a thick, digital glue type (thick and tacky).

I've have succesfully coated prints out of the Xerox 700 with a Duplo UV Coating machine.

I have a Toshiba 5520C. However I've tried prints from some production Xerox units and the result was the same.

The question still was not answered.
My guess would be the stock.
I would also like to know the answer.

The best solution is to let the "solvent" in the ink fully evaporate before the UV coating is applied. Based on their formulations, this could be hours or days, every ink manufacturer formulates differently and their formulations will react to UV coatings in their respective way.

exactly

I'll try to get this sorted out, because I'm sure there's a way to do this. So I'll post here as soon as I have some results

The UV "OIL" mixture sounds to be the problem. What type of UV machine do you have? The spread time may be too long. Try speeding up the UV machine and make sure you turn off any IR heat you are using. If still a problem the companies that manufacture the oil may be of help. I know mine will make custom oils.
