Custom Chinaware - All About Colors
| Color matching in ceramics can be as much
on an art as a science. The thickness of the color, together with
the firing temperature greatly affect the overall look of the image.

Ceramic
Colors |
| We use PMS color references, a.k.a.
Pantone Matching System. Colors are referred to by a Pantone
reference number. Your printer or designer should be able to provide
your logo's PMS color references.
We will reproduce your image using
"spot color" wherein each color in your logo is mixed and printed
separately. This is different from offset printing which uses a four
color process to obtain any color.
Using spot colors, we can match
almost any color in your logo. There are some limitations in ceramics
in addition to those noted below, but rest assured, we will guide
you through the process. |

| Gold Bearing
Colors |
| Ceramic colors in the pink to purple
range, and maroon... contain real gold which is necessary to achieve
color hue without the use of lead or cadmium. This color can be five times the cost of other color. If
your image contains a gold bearing color, we let you know and
suggest alternatives if possible. |

Gold and
Platinum used in the Image |
|
We can print gold and
platinum in a variety of finishes including: |
|
|
| The main difference between
gold/platinum and ceramic color is that gold/platinum is metal and
it sits on top of the glaze rather than sinking into the glaze like
ceramic color. This means gold/platinum will wear. You can actually
take it off with an eraser if you try. This might affect your
decision whether to use gold in a foodservice application. We
discourage using precious metals unless your use is light and you
can hand wash. Nonetheless, we'll bring all this to your attention
in the initial planning session. |

| Lead & Cadmium Issues
Affecting Custom Chinaware |
Since 1980, FDA has had limits on lead and cadmium in ceramic ware products. The limits were lowered in 1991 to reduce consumer
exposure to lead in food from ceramic dishes that may have lead glazes. Most ceramic ware items sold in the United States meet
current FDA limits because manufacturers tightly control the way they make dishes to minimize the potential for lead to leach into food.
Since the FDA regulations were put in place, most reputable ceramic color manufacturers have developed "low lead" color palettes
that achieve most colors and still meet the FDA guidelines. If there are large amounts of low lead color on a plate, we can print a
flux, ie. glaze, coat over the colors to further encapsulate any lead. We can then have an independent lab test the chinaware to insure
that it meets FDA requirements.
Our knowledge and experience will keep you on the right side of applicable regulations.

Unleaded Color Palette

The
California state government in 1986 passed legislation that is
intended to warn consumers in the state of the possibility of
exposure to toxic chemicals. Officially known as the Safe Drinking
Water and Toxic Enforcement Act of 1986, it is better known by its
original name of Proposition 65.
Proposition 65 requires the State to
publish a list of chemicals known to cause cancer, birth defects, or
other reproductive harm. Currently, there are around 750 chemicals
listed, with lead and cadmium being the chemicals of concern to
decorators of chinaware..
Proposition 65 requires businesses to
notify Californians about significant amounts of these listed
chemicals in the products they purchase, in their homes or
workplaces, or that are released into the environment. Proposition
65 specifically lays out the required testing method, limits for
lead and cadmium leaching, and the warning requirements for articles
that exceed the limits.
Limits for warning purposes are
covered in the following document:
Heavy Metal Limits
Ceramic ware does not need warnings
if the leaching test results are below the specified levels shown
above. To achieve this, the lead free color palette at left is
required. It should be noted that ceramic dinnerware can
exceed these limits and still be legally sold in California. If
these limits are met or exceeded, Proposition 65 requires warnings
(see label at left) be provided to inform consumers of the potential
exposure to the toxic chemicals. In addition, Federal limits still
apply.
We can discuss these issues in more
detail if they apply to your company. |
