Printech Archives, May 1998: Requirements for 'Printed with Soy Ink' logo

Printech:

While checking into soy ink use in form printing, I came across some
information on the familiar 'SoySeal' trademark, which contains the
words "Printed with Soy Ink". There has been some previous Printech
discussion on this topic which questioned how inks qualified for the
'SoySeal'. Hopefully this will answer some of the questions.

The following is an exerpt from a fact sheet produced by
the National Soy Ink Information Center, <www.soyink.com>.
The fact sheet is available at <http://www.soyink.com/newfact.html>.

The 'ASA' reference is to the American Soybean Association.

For an ink manufacturing company to be eligible to apply the "Contains
Soyoil" SoySeal to its product containers or product literature, the soy
ink product must meet certain minimum requirements for soybean
oil content.

With the help of the ink manufacturing industry, ASA established these
standards for soybean oil content in printing inks:

Black News Ink
40 percent of total formula weight

Color News Ink
30 percent of total formula weight

Sheet-fed Ink
20 percent of total formula weight

Heat-set Ink
7 percent of total formula weight

Cold-set Ink
30 percent of total formula weight

Business Forms Ink
20 percent of total formula weight

Soy ink may contain other vegetable oils--classified as drying
oils--but soybean oil must be the predominant oil. Vegetable
drying oils may be added as needed, but they must not exceed
the level of soybean oil set forth in the respective
formulation.

For an ink manufacturing company to be eligible to apply the
"Contains Soy Protein" SoySeal to its product containers or
product literature, the soy ink product must meet these
minimum requirements for soy protein content:

Flexographic Ink
The vehicle must contain a minimum of 20 percent soy
protein; a minimum of 15 percent of the vehicle must be
included in the ink.
