HIGH OPACITY WHITES

[DMan]

Hello All

Can anyone recommend me the anilox specification to print HIGH OPACITY WHITES..
I see issues with smooth transfer of inks on many articles...
What is the screen volume range I should look at ?
Will 30 degrees Channel engraving be better among all types available today ?

Await to hear you all

We have used 30, 60 and 75 degree. Also have tried Harper's newer XCAT design. The best results we're coming up with for a nice laydown and decent opacity is Apex GTT C8 (5.16). I only use the GTT's for white....no other colors. We are also surface screening our white plates. FYI - we only run water based ink. Hope this helps.

If you are running water based inks on clear film, it is going to be difficult to achieve a real opaque white regardless of anilox or ink manufacturer. Your best bet would be to invest in a UV lamp for the first print station to lay down a UV opaque while.

Hi, try the HOW anilox range from Sandon Global. we normally go with the HOW3. running UV Opaque white.

One of the open channel style anilox rolls is ideal, there is many names for them from the suppliers. The trick though for smooth coverage is a super hard plate tape and a plate with micro-screening. Without a hard tape and a solid plate you will always see pinhole and not a smooth lay down with white.

I fully agree. if you are using UV inks the Sunchem Neutron white is the most opaque of all suppliers I have tested.. used in combination with the above you'll get your best result.
