<br>
I am not a coatings expert, but here is a short coatings description based<br>
on my experience. (I am presuming that "Finishings 2.0" is focused on<br>
post-press operations):<br>
<br>
The coatings listed in JDF's ColorIntent Resource Table can be applied<br>
either inline or offline. Offline coatings (finishing) are typically<br>
intended to be protective. They can increase water-resistance,<br>
scuff-resistance, and even food resistance in the case of restaurant menus.<br>
They have been used for decades to protect offset printed sheets, and usage<br>
has increased with the desire to protect digitally printed sheets,<br>
especially photo images. Like varnish, they come in gloss & dull variants.<br>
<br>
The most commonly coating types requested by customers today are UV coatings<br>
(Ultra Violet cured polymers) which provide higher durability, and aqueous<br>
coatings that are viewed as "greener" and typically more easily recycled at<br>
end-of-life. Both types of overall coating protect the printed image as well<br>
as the substrate. They also may be applied over foil embossed surfaces in<br>
some instances.<br>
<br>
Customers may also specify the performance characteristic they desire in the<br>
coating rather than specifying a coating type. Common examples are<br>
water-resistance, and rub-resistance. Both characteristics may be required<br>
at the same time. An example is in the wine industry, where the white wine<br>
label has to survive transport rubbing, followed by water and rubbing ice<br>
cubes in a bucket upon serving.<br>
<br>
Does this help?<br>
