Print white lines

How can I print my drawing onto black paper so all lines are white? Where can I change the color settings etc to do that?

What kind of printer are you sending your output to?

I have some kind of Samsung CLX laser printer. Don't know much more.

See if you can get a model number.

Have you used this printer before to do color output?

Most printers will have a black, blue, red and yellow cartridge. No white that I know of.

On most printers, a white line or bit of text is simply a lack of ink or toner in that spot, surrounded by a colored background. There are a few inkjet printers now that actually print in white ink, but I don't know of any laser that will actually print in white.

Epson makes a printer and a white ink, you can see it here: http://www.colorhq.com/Stylus-Pro-WT7900-by-Epson-24-Printer-p/spwt7900.htm?gclid=CMiPpOzD9KgCFcZe2godiAj5TA

It's about $8500 msrp. There are a few others, but they are all pricy.

I suppose you could try to find an inkjet compatible ink somewhere and try your hand at refilling an empty black cartridge. Might take a while to get all the black out though.

I do not think you can print any color effectively on Black paper.

I read that over 3 times and it still doesn't make any sense to me. I just don't see how magenta, cyan, yellow and black can possibly combine to produce white.

You don't print white on black you print black on white ! Unless like above you have spent heaps of money never knew white ink ever existed. I do know about a product called whiteout but its pretty hard do do and you must have a steady hand.

You can get white speedball or printer's (as in screen printer) ink at any hobby/art supply store, but it won't work in inkjet printers. The reason you can get such vibrant colors from an inkjet is because the ink is actually transparent, so the better quality paper you print on, the more reflection you get back through the ink from the paper. That's why "photo" paper is thicker than regular paper, and has a slick or glossy finish. It's just porous enough to let the ink have something to grab on to.

Laser printers lay down an electrostatic charge that attracts the toner and holds it there while applying heat to make it adhere to the paper. If you print really large colored in sections, and then fold the paper, the toner will sometimes turn loose of the paper and flake off. Just as with ink, a laser printer mixes the colored toners to produce all the other colors you see. There is no white cartridge. If you want white, it simply doesn't deposit toner there.

You need to work with a color wheel a little more to understand it fully maybe, I know it just seems strange. I have had jobs using color wheels and mixing colors, so that article made good sense to me.

 

Pretty sure that article was talking about inkjet the more I read it, though the process could work on laser, not sure about that.

 

What that article is really saying is that

But unfortunately, the problem is that the color printing inks--cyan, yellow, magenta and black--are actually transparent. If you try to print light-colored ink on dark paper, the ink won't show through. However, you can get around this by printing a black background onto the paper and the white text over it.

Quote from your link: Additive and Subtractive color spaces in a cube

As you can see, the subtractive primary colors (cyan, magenta and yellow) connect at the top with white, the point where you don't add any pigment. Each of the single pigment legs branch out from white.

The light color branches are emanating from the black point at the opposite corner of the cube from white. They end in the additive primary colors (red, green and blue).

White...the point where you don't add any pigment.

It works on TV screens by projecting colors that will cancel. Light travels in a wavelength, the same as radio or sound. They have a positive and a negative. White is produced in the same way noise cancellation is produced. Pigments don't project light, they reflect what is already there.

Correction...It works on TV screens by projecting 'wavelengths' that cancel. Fingers out ran my brain.

article says that red+blue+green = white and I tried that in autocad in solid hatch using true color & by maximising the value of all three to 250,250,250 I could achieve 'WHITE' hatch on screen

so thanks for the informative/intresting link

That's true...works on a monitor because of what I said above. Go to the paint store and try it. Ain't gonna happen.

Fill the black ink cartridge with White-Out How about color 255?

clipped from the help file:

The third palette displays colors 250 through 255; these colors are shades of gray.

You make shades of gray by printing black dots. Closer together the dots, the darker the shade of gray. If you print it on yellow paper, it will have a yellow back ground. If you print color 255 on black paper, it will be black.

Mixing colored light is not the same thing as mixing a liquid with a pigment. If you stick a magnifiying glass up to your monitor or tv, you'll see a whole bunch of little colored dots, even in the white areas. You're not mixing the colors to get white, the electronics are varying the phase to cause cancellation. Light travels in a sine wave, same as sound or radio, as I said earlier. Opposite phases cancel, the same way noise cancelling headphones mask background noise. These things can be projected to cause a particular effect. Printed colors on a paper do not project, they reflect. They change it's direction, but not its phase. You can't mix pigments to make white. The printer I posted the link to above even describes creating the "illusion" of seeing white. Quote: Epson UltraChrome HDR White Ink introduces an all-new Organic Hollow Resin Particle Technology, which forces light to randomly scatter, producing the illusion of seeing the color white.

:lol::lol:

At what point is color NOT reflected light? All color is reflected light therefore an illusion. Your computer, your desk, your paper etc. etc. all an illusion, just ask someone with colorblindness.

Ok...i give up. When someone figures out how to make an ordinary printer print in white, he/she will be richer than Bill Gates. When you can mix pigments to get no color at all, then the next thing you should turn your attention is alchemy. There's gotta be a way to turn lead into gold, too.
