Digital BW, The Print

I've used this Lyson spray for 4 years on all media. It works great, just like the Premier Art. 
Most likely these are the same chemical components. It is just that big Wilhelm hasn't 
tested the Printguard and published fade data about it so they are loosing out in sales to 
Premier, BIG TIME. That is probably a disgrace, and Lyson proabably invented the product 
in the first place or at least made us aware of it. I use them both.

I've used it on giant matte, luster, canvas, rag, etc. prints for years, especially in areas of 
large black because these areas are the most vulnerable to skuffing. I don't understand 
why anyone should have trouble with these sprays, they are so easy to use. Just follow the 
simple directions.

I have a good filtered mask that I bought from home depot for about $28.00. With one of 
these masks you wont smell anything or damage your brain. Also it is important to wear 
goggles because when doing very  large things you can damage your eyes over time. Just 
use common sense and you will be fine. Try to have as much ventilation as possible.

The only down side to the uv sprays is that they can reduce the d-max in very deep blacks 
somewhat with some inksets, such as carbon pigment. This is really more of an issue for 
me with small delicate prints. In that case I use Lascaux, that Paul Roark  on this site has 
recommended to us all. Do a search on this site for that info. That spray stops the 
scratching and skuffing and protects agains moisture but doesn't protect agains UV.
