Hi, It is my understanding that you could get different gloss readings when using different presses. There are many factors that can influence the final gloss level from what I am told.

Here is my plug (sorry for the salesmanship): The coating blanket itself is one of the factors that can contribute. If you are looking for a coating blanket that will provide you with the highest gloss possible with UV gloss, please contact me. We have some excellent coating blankets.

There are a few variables for gloss levels two or three roll coaters or anilox each will give a different gloss level.two and three roll coaters you can adjust the volume of coating being applied by opening the nip or speeding up the metering roller.anilox you must change the roller to a higher BCM . Viscosity can also come into play . A deicated uv blanket will also help out with your gloss levels. After all that if you are running the same uv and same type of coating system you should be close on gloss levels. If you have access to a gloss 60 degree
gloss meter it would help .
