Q:What does pigment mean?
The natural coloring matter
Q:what is pigment ink???????
Some printers use only pigmented ink. Others use dye based and then some use a combination of both. Dye based ink is basically water based with a dye added to it. Pigmented ink has a solvent base with dye added. Pigment ink and dye based ink have both advantages and disadvantages. Dye based ink have better colors but pigment are more water and fade resistant. Dye based inks are therefore better for photos. I have a printer that has 4 dye based inks and a black pigment ink. Mine uses the dye based black and colours for pictures and the pigmented black is used for text. So the answer is yes. Pigmented ink is used in some regular printers.
Q:Pigment or regular eyeshadows... what is the main difference?
Pigment is the purest formula or color with minimal ingredients mixed in to buffer or thin out the product. Generally, the loose form is the most intense because it is lightweight and you can pack it on, mix with a medium, or layer. Pigments usually cost more than pressed forms. However, there are some pressed pigment shadows that are awesome (NARS, Make up for Ever, Urban Decay)! MAC has excellent shadows, I use a lot of them (loose pressed) in my kit. Loose pigments are great mixed with water or mixing medium to intensify. They also will last you forever!
Q:How do you make paint pigments?
Pigments are specific minerals found in rocks. Then they are ground down and mixed with the binders for oil, acrylic, and watercolor paints. You can take art classes that teach you how to make your own paints. I have a cousin who hikes to find her own pigments and makes all the colors she paint with. If you'd like something less labor-intensive, you can buy the pigments you want from lots of art stores these days. They can be added to pre-existing colors to enhance them, or you can start from scratch to formulate your own colors. The bottles i've seen are around 8 ounces, and cost about $50. You will likely find books in the library and articles online that will help you learn to make your own pigments.
Q:What is a Pigment?
The most important characteristics of pigments are: 1. They impart a colour to the medium to which they are applied. Remember that you can get white pigments, titanium dioxide, and black pigments, carbon black is typical. The pigments impart a colour merely by their presence , they are mostly chemically inert.They need some binder to fix them to the substrate. 3.They are insoluble in the carrier in which they are processed. 4. Pigments can be inorganic or organic, but the majority have a metal in their structure. 5. Pigments can occur naturally, but synthetically produced pigments to precise standards are by far the most used in industry. 4. In contrast to this, colourants that dissolve in the medium in which they are processed are called dyes or dyestuffs. 5.Dyes are by and large purely organic in structure, and do not contain metals in their chemical formulation. 6. Dyes undergo a chemical reaction with the substrate which they colour. 7. There is also a third type of product called an extender or filler. In the surface coating industry clays, calcium carbonate, etc fill this role. They do not add any colour to the paint, they become transparent in the paint binder medium, because of their low refractive index. They add body to the paint.
Q:Pigmented microorganism?
Pigments have many advantages for the cell. They can absorb light to be used in photosynthesis. Specific pigments absorb light in a specific range - so the more pigments the more light can be absorbed and used for photosynthesis. Pigments also protect the cells from damage by UV radiation. More recently it has been suggested that some pigments inhibit the growth of some microorganisms.
Q:what is the function of plants pigment?
plant pigments are of types---- LUCOPLAST- colourless, found in roots, collect food.,,, CROMOPLAST-- Of difrent colour (not green), in flowers atract insect for polination, in fruits atract animals for seed dispers,,,,CLOROPLAST-- Convert light energy to chemical energy, in leaves and otner parts....
Q:can the pigment know as Chinese purple form a matter wave in certain circumstances?
Scientists explore atomic mysteries of ancient pigment LOS ALAMOS, N.M., Nov. 18, 2004 -- University of California scientists from the National High Magnetic Field Laboratory, Pulsed Field Facility at Los Alamos National Laboratory, working with colleagues from Tokyo Metropolitan University, the University of Buenos Aires in Argentina, the National Institute of Chemical Physics and Biophysics in Estonia, the National High Magnetic Field Laboratory in Tallahassee, Florida and the University of Tokyo, have discovered an ideal candidate for Bose-Einstein condensation in the ancient Chinese pigment, Han Purple. In research featured recently on the cover of Physical Review Letters, the team describes how the application of a strong magnetic field to Han Purple (BaCuSi2O6) creates a gas of bosonic spin triplet excitations. The field acts as a chemical potential causing the weakly interacting bosonic gas to undergo Bose-Einstein condensation (BEC) when the temperature is reduced to minus 453 degrees Fahrenheit, six orders of magnitude higher than the temperature normally required for BEC in atomic gases.
Q:What does the word pigment mean?
meant to be a pig. :)
Q:what pigment are? give two example?
pigments found in plants, vegetables and fruits, make them look colorful. pigments found in animal skins, givie us colorful animal skins with variety of shades. Plant pigment Chlorophyll makes plant leaves look green. Plant pigment Carotenoid makes fruits and vegetables look orange, yellow, red. Plant pigment Phycobilin makes plants look bluish green or red.
