From the ESI (Now a part of Nicoat) Data Sheets: GENERAL WET ON WET APPLICATION 1. Generation III Ink Train Coating dries quickly. The top sheet will dry in 2-4 minutes and the stack will dry in approximately 10 minutes. Drying can be improved by the use of a hot air knife positioned before...

Geeze, sorry I'm Late? Ok, I'm suspecting the Viscosity reading was taken with a "#4 DIN Cup", and NOT a "#3 Zahn Cup". I suspect this, because the press likely came with it, and other than North America, the "DIN Cup" is likely the most popular. (Pretty much every Heidelberg delivers with...

Works ok, made in Korea, but Pantones still made in the Netherlands. Good Product!!

So, JLIND, I believe that your term "interferance" is a newish term that I certainly didn't hear of before?! I thought you meant that the Blanket Sales Rep was "Interfering" with your Test? I am suspecting that Gordo's inquiry was Voiced because in Gordo's (and My World of terminology) this...

Knowing how much to use Overprint Varnish is clear when its printed. So how do you know if your running too much or too little? Most printers can judge this without any problem because they have done it numerous times and have just developed a sense about it. However, if this is your first time...

Why does the ink cause "Scumming"? Are you using metal (aluminum) printing plates? Polyester Printing Plates? Paper Printing Plates? What fountain solution product are you using? (Brand Name?) What mixture are you using? Are you running with Tap water? Well Water? Are you running with...

The only physical difference between "Oil Based Inks" and "Rubber Based Inks": "Rubber Based Inks" are "Oil Based Inks" without "driers" added to them. As a result, they dry through absorbtion into the paper stock. So, they wont work well on "Coated Papers". "Oil Based" Inks have driers...

Actually, the private branded Saphira Printing ink used to be Kohl & Madden. 6 months ago it was "secretly" changed to the Superior Printing Ink Brand from the United States ;-)

Pehaps by now, your problem is solved? However, "flyby54" has the answer. I experienced this on several occasions. In fact, had such a buildup of ink outside of the print area that it was smashing blankets!! Changed to 3 different fountain solutions over 2 days!!! Couldn't solve it...

In Ontario, Alcohol is to be used only after Printing ;-)

Check paper grain direction? Or turn press right side up? Just kidding, try the paper grain direction? When you are printing, you print with ink, and water. Possibility that paper is taking on water (which it has to), then when the sheet dries, it is shrinking slightly. Remember, it is only...

Titanium Dioxide used to be used, but as the name suggests, its more expensive than "Dirt" This Company actually advertises it as a "Pigment" ?! Calcium carbonate | Kaolin | Imerys Pigments for Paper

Try this link, halfway down the page? NSSGA: Communications - Who We Are: Calcium Carbonate - What is it? Or this? Precipitated Calcium Carbonate Or here? Natural Calcium Carbonate Powder, Natural Calcium Carbonate Drilling Additives for Oil Exploration Industries, Natural Calcium Carbonate...

Hello, perhaps you could try using a calcium rinse in the Magenta ink train? Unless you have a single tank for each unit of the press, most fountain solutions don't know what color the ink is, so if it's only the Magenta ink, I suggest looking at the Magenta unit of the press. As Calcium...

Ok, using RO water gives you a more consistent starting point for mixing fountain solution. Chlorine content, spring runoff, old pipes, and even local construction can introduce excess particulate in your water. This can throw off your conductivity measurement when mixing fountain solution...
