Free radical uv inks will post cure around 5%, if grossly undercured they will never link up. Poor adhesion and a short outdoor life will be the reality. Cationic UV inks will continue to cure once initiated. These were initially used for LED curing systems, I think most have moved back to free...
The odor is the result of free monomers aka uncured inks. If the inks cure 100% there should be no odour.
However wood products with none of minimal coatings will absorb the ink making harder to cure.
Some of the printers inks need better photoinitiator packages or the printers should have...
Ground level ozone (by product of the curing process) and being sensitized to uv inks are two different issues.
I have seen color matchers become sensitized and they were not near the presses. I have not heard of, or seen a press operator sensitized although it could happen.
I understand the...
Having sold UV inks since the 80's I have seen where some people become sensitized to UV inks.
You may be getting some residual ink on your skin from the prints that have not totally cross linked.
When washing your hands use soap that has absolutely no lanolin. Hope this helps, in many cases...
A screen printing ink manufacturer can match it for you. Tell them you are spraying it or whatever way you are applying and they will match it thinned appropriately for the process.
Thanks for clarifying. Most coatings can be matched to pms with a white background. Most likely a spectrophotometer will not be necessary and a side by side approval of a sample would be sufficient. Good info from you, thanks!
I am curious, how well does the mathews paint match pms on clear stock? the pms system is based on a white background. I am not disputing if it works or not as i have no experience with their paint. Do you make an opaque colour closest to the pms#?
Melamine can be a challenging substrate for ink to adhere to. If you are going flatbed, then have the printer manufacturer or someone local that has the printer you covet test print on the melamine for adhesion. Roll to roll print and laminate may be the best bet as the inks will be protected...
