Photography Question

green printing

I'm looking for an online printer that uses recycled papers and vegetable-based inks. Know of anything like that? I've googled every combination of words I can think of, and I come up with lots of businesses, but they're not really photo printers, they do business cards and flyers.

Alan N. Marcus   Stuff about dye:

I know you feel better being green.

First a physics lesson:
Photographic film and papers and their related digital counterparts function using just three colors plus black (black is not an ingredient used in conventional color films or papers.

All are organic!

The only three colors that work are cyan a combination of green + blue – yellow a combination of red + green – magenta a combination of red + blue. When in comes to making colored images on paper. The choices for cyan – magenta – yellow are exceedingly narrow.

A dye is a liquid that has color. A pigment is a solid that has color.
The natural colors are annatto – beta-carotene – carmine – saffron – turmeric – indigo.

Chemistry lesson: The dyes used are AZO an adjective describing acidic dye derived from amino compounds. These are organic compounds of nitrogen derived from coal.

Additionally the amino acids are essential to life but cannot be synthesized in the human body thus we obtain them from food, they are present in the casein protein a white, tasteless, odorless protein precipitated from milk by rennin a gastric juice.

The black dye is carbon suspended in water, or ferrous gluconate it comes from ripe olives, high in iron is the iron supplement used to treat iron-deficiency anemia.

Lycopene is colorful carotene. The molecule of lycopene oabsorbes blue light thus it appears yellow. This is the beta-carotene of vitamin A derived from leafy plants.

Anthocyanine is another class derived from flowers, blueberries, apples and red cabbage. It gives these plants their color which is dependent on how acidic or alkaline they are.

Cochinean is a red dye derived from the female insect (eggs of ) Coccus cacti or Dactylopius coccus. These insects live on the prickly pear cactus in Mexico.

The study of dye wouldn’t do you any harm.

Stephanie M. Stevens   That's wonderful, but the traditional printing industry is the single biggest polluter in the world, and I would prefer not to be a part of that. Thus, the search for alternatives.
