Artificial water marks on paper resemble the actual water marks created during paper manufacture. These are created through some sort of printing machines useing opaque white special inks. I would like to know what are these machines and where do I get them.

Well the thing s tat Artificial watermarks are applied after the paper manufacturing process. They can be applied by the paper manufacturer or by the printer. Many paper manufacturers offer stock security papers that have a standard artificial watermark applied to them. The cost of the security paper with an artificial watermark is generally a little less expensive than one with a true watermark.\n\nAn artificial watermark can be seen from one side only. It is generally applied to the back side but can be applied to the front side also. The watermark is achieved by printing the image in opaque white ink, transparent ink or by using varnish. They will all produce an image that is visible when viewed at an angle. An artificial watermark is sometimes also referred to as ghost printing. Artificial watermarks are nearly impossible to duplicate by copier or scanners, making this a good security feature to add to your documents.\n\nAdding a customised artificial watermark to your document will make it even more difficult to duplicate. Customising an artificial watermark is less expensive than customising a true watermark. The customising can be accomplished by the paper manufacturer or the printer. The most cost effective alternative will depend on the quantity of watermarked paper needed.

What your actually thinking of are baffles. These cause the water to travel in a zig zag way or even perpendicular to flow direction. This slows the water by taking its Kinetic Energy and so reduces wear on other structures or machinery

It is just a security feature in the checks. A watermark is a fine print in the check paper usually with the word "VOID" all over. If the document is chemichal altered it will appear on the check making it invalid. If the document is copied or scanned the mark will show in the duplicate. You can buy this type of paper in STAPLES or in many office suply stores. Also, if you have a High Resolution printer and your CHECK PRINTING SOFTWARE has the feature you may be able to print them. Again it's just more security, it will not make the checks illegal.

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.

try writing it on paper and comparing it with other types of ink you've made or have.

No heavy, toxic metals in printing ink that I know of.  The black color comes from carbon black (soot).  Colored inks use other organic pigments.\n\nNewspapers used to use lead (Pb)-, cadmium (Cd)-, and chromium (Cd)- based inks, but that practice was discontinued years ago.\n\nCheck it out here:\nhttp://answers.google.com/answers/threadview?id=97405

Often they use pad printing... they find a mold to hold each product in exactly the same spot... then a thing comes over... presses down and puts the ink on... but there are other methods as well...

It's called a watermark, it's there so you don't use them for purposes other than what the creator wanted you to use them for.

Lines are printers signs of ink running out or the printing heads being dirty.  The effect is called "banding".  You should use the utility panel on your printer control screen to clean the printing heads and nozzles. Or if the problem continues, replace the ink cartridges.

Flowers drink water with a capillary action.  Capillary action happens when water molecules are more attracted to the surface they travel along than to each other. In paper towels, the molecules move along tiny fibers. In plants, they move through narrow tubes that are actually called capillaries. Plants couldn't survive without capillaries because they use the water to make their food.  There is an experiement you can try at the link below.

ERASERS are made from either a synthetic rubber compound or from vinyl. In either case, the raw material is blended to the proper consistency and is put into a machine called an "extruder." The eraser material is forced through a small hole producing a long ribbon of eraser.\n\nEach ribbon is cut into strands about 3 feet in length. If the eraser is made of synthetic rubber, the strands are placed in a "vulcanizer," which cooks them under pressure to cure the rubber. When cool, the strands are put into a rotary cutter and chopped into bits -- called plugs. (Vinyl eraser strands go straight to the rotary cutter -- vinyl does not need to be vulcanized!)\n\nHistory\nPrior to using rubber, white bread (without crust) was used to erase the mark of graphite pencil and charcoal. It is still sometimes used for that by charcoal artists.\nIn 1770, scientist Joseph Priestley noted, "I have seen a substance excellently adapted to the purpose of wiping from paper the mark of black lead pencil."\n\nAlso in 1770, Edward Naime, an English engineer, is credited with creating the first rubber eraser, and reportedly was selling natural rubber erasers for the astonishingly high price of 3 shillings per half-inch cube. According to Nayme himself, he inadvertently picked up a piece of rubber instead of breadcrumbs, discovered rubber's erasing properties, and began selling rubber erasers. Incidentally, this was the first practical application of the substance in Europe, and rubbing out the pencil marks gave it its English name.\n\nHowever, rubber in its raw form shared the same inconveniences as bread, since it was perishable and would go bad over time. In 1839, inventor Charles Goodyear discovered the process of vulcanization, a method that would cure rubber and make it a durable material. Rubber erasers became common with the advent of vulcanized rubber.\n\nIn 1858, Hymen Lipman of Philadelphia, Pennsylvania, USA, received the first patent for attaching an eraser to the end of a pencil. It was later invalidated because it was determined to be simply a composite of two devices rather than an entirely new product.

You might want to use different paper...   i would get the blotting paper from a blot spot, they'll have variants.

Back in the late 1600's, the Dutch invented the two-sheet mold.   The average maximum stretch of an experienced vatman's arms was 44".  Many molds at that time were around 17" front to back because the laid lines and watermarks had to run from left to right.  Sounds big?...well to maximize the efficiency of paper making, a sheet this big was made, and then quartered, forming four 8.5" x 11" pieces. \n\nThis was well before paper machines dominated hand made paper labor.   A couple centuries later when machines dominated the trade (although many hand made paper makers still existed), and the United States decided on a standard paper size, they stuck with the same size so as to keep the hand made paper makers in business.\n\nOddly enough, the United States used two different sizes - the 8" x 10.5" and the 8.5" x 11".   Separate committees came up with separate standards, the 8" x 10.5" for the government and the 8.5" x 11" for the rest of us.  Once these committees found out about each other a couple years later, they agreed to disagree until the early 1980's when Reagan finally proclaimed that the 8.5" x 11" was the official standard sized paper.\n\nUnited States History\n\nNot until World War I or shortly after was a standard paper size agreed to in the United States.   Interestingly enough, within six months of each other, two different paper sizes were set as the standard; one for the government and one for the rest of us. \n\n1.   In 1921, the first director of the Bureau of the Budget established an interagency advisory group with the President's approval called the Permanent Conference on Printing which established the 8" x 10½" as the general U.S. government letterhead standard.   This extended an earlier establishment made by the former President Hoover, the Secretary of Commerce at the time, who established the 8" x 10½" as the standard letterhead size for his department. \n\n2.   Now, during the same year, a Committee on the Simplification of Paper Sizes consisting of printing industry representatives was appointed to work with the Bureau of Standards as part of Hoover's program for the Elimination of Waste in Industry.   This group came up with basic sizes for all types of printing and writing papers.  The size for "letter" was a 17" x 22" sheet while the "legal" size was 17" x 28" sheet.  The later known U.S. letter format was these sizes halved (8 ½" x 11" and 8 ½" by 14").\n\nEven in the selection of the 8 ½" x 11", no special analysis was made to prove this was the optimum size for commercial letterhead.   The Committee that developed the sizes did so using one objective - "to reduce inventory requirements for paper into sizes which would cut from a minimum trimming waste."

1. No, voting ink is not the same everywhere. \n\n2. These indelible inks have different composition and the composition is safeguarded by it manufaturing companies.\n\n3. Why do you need to get rid of it ?

If you're using an ink-jet printer, it sounds like the print heads need cleaning.  You often get white lines when dirt or dry ink builds up.  You can use household items to clean, but it's probably best to buy cleaning cartridges.  See the links below for further information.\n\nhttp://www.e-inkjet.co.uk/cgi-bin/cleaning.asp\nhttp://www.cartridgesave.co.uk/info/inkjet-cleaning-cartridges.html

easies is a magic marker it is very dyi but if done well looks awsome. You can buy patches and sew them onto a t, or you can buy iron on printer paper and download a logo and print it and iron it on. I would probably suggest the magic marker if you are artistic or sewing on patches. good luck

Look for water mark images by holding up to the light.  Look for plastic strip. Look for color changing ink,etc.
