how is water reactive ink work?
545525
I think what that means, if I am not wrong, is water that is soluble and can mix with ink. Most pens have this feature, or should i say ink pens. They are not resistant to water so if there is water on paper, if you try writing over it, the ink would still make a mark on the paper instead of being repelled some where or not even made a mark. \n\nIf what I say above is correct then hop down to any stationary shop to grab some ink pens to see how it works.

Pure water is transparent and can not change the color of a cloth.  However, when light (photons) enter say blue cloth all the wavelengths that are not blue are absorbed and the blue is reflected.  However, these blue photons are diffused through the cloth.  Adding water allows the photons to interact with water molecule electrons and escape unchanged much easier to your eye and the true color of the cloth dye becomes apparent and darker.  It is also true that when you mend cloth the thread you use only needs to be a close color match (not identical).  A single thread is too small to reveal its true color and will blend (and become overwhelmed) with the overall cloth color.  Notice that white paint does not get darker when wet with water.  All photons (every wave length) are still reflected.

You probably have an inkjet printer.\nAn inkjet printer works by spraying small amounts of ink on the paper.\nThe other type of printers are laser printers, which first create an electrostatic image on the paper and later with the help of toners, ink in attracted to the electrostsatic image and is pressed on to the paper by heating.

I assume this is based on the principle of Osmosis. I would like a bit more data before answering further.

Use English dear.  Putting "Why" in front of an instruction does not a question make.\nI assume you are referring to a chromatogram.\nThe simple answer to the obvious question is that ink is comprised of one or more organic pigments (often phthalocyanine based) and will develop on a chromatogram just the way the applied pigment will.  This will confuse you beyond your wildest expectations.\nInstead, use pencil, which is primarily graphite (a form of carbon) which will not be carried up the chromatogram by the solvent mixture.

Newspaper ink used to be oil based and never fully cured, so it came off easily on your hands.\nNowadays, newspapers are printed with water based inks, which 'cure' by volatilisation of the amine from the polymer solution. The ink is still susceptible to attack from mild bases, (such as milk perhaps).

The cartridge with the ink in it executes that function.LOL\n\nAn inkjet printer is any printer that fires extremely small droplets of ink onto paper to create an image. If you've ever looked at a piece of paper that has come out of an ink jet printer, you know that: \n\nThe dots are extremely small (between 10 and 30 dots per millimeter). \n\nDifferent types of inkjet printers form their droplets of ink in different ways. There are several technologies used by printer manufacturers, but by far the most popular technique is the bubble jet. In a bubble jet printer, tiny resistors create heat, and this heat vaporizes ink to create a bubble. The expansion that creates the bubble causes a droplet to form and eject from the print head. A typical bubble jet print head has 64 or 128 tiny nozzles, and all of them can fire a droplet simultaneously.\n\nThe primary principle at work in a laser printer is static electricity, the same energy that makes clothes in the dryer stick together or a lightning bolt travel from a thundercloud to the ground. Static electricity is simply an electrical charge built up on an insulated object, such as a balloon or your body. Since oppositely charged atoms are attracted to each other, objects with opposite static electricity fields cling together.\n\nDye-sublimation printers allow you to print photo-lab-quality pictures at home. As the price of these printers go down, more and more digital-camera owners are choosing to take advantage of this technology. In dye-sublimation printing, colors are not laid down as individual dots, as is done in inkjet printers. Individual dots can be distinguished at a relatively close distance, making digital pictures look less realistic. \nIf you looked inside a dye-sublimation printer, you would see a long roll of transparent film that resembles sheets of red, blue, yellow, and gray colored cellophane stuck together end to end. Embedded in this film are solid dyes corresponding to the four basic colors used in printing: cyan, magenta, yellow and black. The print head heats up as it passes over the film, causing the dyes to vaporize and permeate the glossy surface of the paper before they return to solid form. \n\nSo the main difference between this and other types of printing has to do with heat. The vaporized colors permeate the surface of the paper, creating a gentle gradation at the edges of each pixel, instead of the conspicuous border between dye and paper produced by inkjets. And because the color infuses the paper, it is also less vulnerable to fading and distortion over time. \n\nThe dots are positioned very precisely. \nIn color printers, the dots can have multiple colors\n\n\nemail me at: hell_stinker@yahoo.com\nhope I answered ur question !!!

You could easily (and cheaply?) demonstrate capillary action, the effect that draws ink up the split nib of an old fashioned pen or quill pen.  Suspend various strip samples of material from a rod over a pan filled with water and food coloring and see how far the liquid clims various materials (diferent natural and synthetic cloths of tight and loose weave and paper and wood, etc.  Make at least two samples of each material so that you can experiment at home and then set up the rig at school in the order you found to show the most to the least capillary action and explain why.  Study one or more websites for an explanation of the effect.  Good luck.

Ink cartridges that have been refilled may work as well as new ones but some manufacturers include lubricates in their ink to help their printers function at the highest quality.  I suggest if you are going to use refill ink cartridge then replace with new ones every so often.

You can make glow-in-the-dark ink with 2 simple ingredients. \n\nPour into a small bottle 1 oz. oil of cinnamon and 1/4 oz. phosphorous. Close the bottle tightly and place in a hot water bath. Heat until the ingredients have melted together.

Your wife's right. And not right too. \n\n==========\nbackgournd \n\nInkjets work by squirting ink through very very small holes in a print head. Canon and HP and several others do that by heating the ink in a chamber just behind the hole, which 'boils' a small bit of it creating a bubble, increasing the pressure and forcing out a microdrop of ink. Epson has done it a different way, with piezoelectric pulsing of the chamber behind the tiny hole. \n\n==========\npossible failure modes\n\nThe holes are relatively easily clogged, so the fineness and uniformity of the particles in it (dyes and such) are important. So is reasonable behavior when partially dried out (not being used for two weeks during a vacation, say) and when heated or subjected to considerable pressure. Hence the cleaning cycles built into many printers (see your owner's manual for some vague and normally not very intelligible instructions).\n\nInks made by a knock off artist in some backroom counterfeit lab somewhere aren't likely to have uniformly ground particles, nor probably the required witches' brew of chemicals to behave well under stress. On the other hand, some third party ink producer might indeed take sufficient care to get it right for a particular type of printer / cartridge / etc. The problem in practice to how to distinguish amongst them. \n\n========\nexperimental test\n\nSome printers have the 'print head' built into the cartridge. You get a new set of teeny tiny holes with every cartridge. With other printers, the print head is in the printer and the cartridge carries only ink. Obviously, in the latter case, a poorly made ink can be rather more expensive. \n\nI had a long policy of buying only print head type cartridge printers for exactly this reason. And I was willing to experiment with cartridges and ink from apparently trustworthy vendors because important parts of the printer wouldn't be at risk. I cannot suggest the at home refill policy unless you can do it wearing latex gloves over a slop sink. A couple of cubic centimeters of ink can go a very very long way; you don't want to find out, but the refill kit I used did work, and the cartridges could be refilled three times at least. The very cheapest way to feed the ink monster that I discovered. Not counting the ink spilled on just about everytihint that one time... But, with printers costing less than US$100 nowadays, the cost of an experiemnt gone bad is limited, except for the time and trouble of replacing the printer damaged by the bad ink. \n\n=========\nDRM measures\n\nSome printer vendors have attempted to force their users to do the right thing (ie, buy their expensive ink -- fo rtheir own quality printing good, of course) by including in their printer measures which try to detect improper cartridges and punish the user by locking the printer to some lower performance level or some other punishment. I heard of a printer which self-destructed under when it detected fake ink cartridges., but never managed to figure out which one it was. You many find that your printer won't print any better than some draft quality if you use a third party cartridge. \n\n============\nalternatives\n\nWith the street price of laser printers below US$150 for low end black and white, and under US$350 for low end color (shop around, at least in the US and you'll find them), there are lots of reasons to avoid inkjets, and their expensive thirst for those .cartridges. Unless, of course you need photographic quality with special archival inks, in which case you might have to use an inkjet.

I'm not sure exactly what you're asking, but if you put a few drops of food coloring in the water with a white flower (like a carnation), it will absorb the dye and the color.

ok shirley, following the instructions the others have suggested get me to where i need to go, but they do not reveal any ink levels, which is what i expected.\n\nnot all printers allow you to check the ink levels on your system.  mine is a laser and there is a menu on the printer which allows me to find the usage.  however, my daughters doesn't have either.\n\nsometimes you need to watch it yourself.  if you feel that the ink carts you have in the machine have been printing for like forever, feel free to get a new one as a back up.  keep it in a cool dry place, as a warm dry place will dry out the cartridge if kept there too long.\n\nwatch the pages as they print.  when you notice that the ink is getting lighter or you begin to see streaks in the printing it is time to replace the cartridge.  if you are able and wanting to refill them, DO NOT RUN the cartridge empty, as it will ruin the cart and you will not be able to refill it.  once you remove it from the printer, you may dispose of it, place it in a plastic zip close bag with a slightly damp paper towel until it can be refilled, or use it at your local officemax/staples to get a free ream of paper, or maybe your local video store will give you a free movie rental if you turn it in.\n\nagai, not all printers allow you this opportunity.\n\nhope this helps\ngood luck
