How does cmyk make red




















Desktop color printers—inkjet or laser—also use CMYK inks or toners, but work in one pass for an image with multiple nozzles per pixel. Professsional inkjet photographic printers may add intermediate ink colors such as light cyan or even orange. Again, software for each specific printer model will do all of the conversion work for you. Like the additive color model , subtractive color mixes wavelengths of light to produce what we perceive as color.

However, the subtractive model uses pigments or ink to block — subtract — light rather than adding it. Combining two pure additive primaries produces a subtractive primary. The subtractive primaries of cyan, magenta, and yellow are the opposing colors to red, green, and blue. When two subtractive primaries overlap, an additive primary is produced. When all three subtractive primaries overlap in equal quantities, all of the light is subtracted and we perceive black; the absence of light.

To render color on paper, printers use reflected light and subtractive color inks. By laying Cyan, Magenta, and Yellow pigments upon a white, reflective substrate, each absorbs — or subtracts — its opposing counterpart from the white light. You certainly can get real red, it just appears that, as you say, your output profile is shifting it quite a bit.

Pull some yellow out of of it once it's in CMYK mode or pump in some magenta and it should look fine. Though, of course, as Ryan notes, what you see on your screen is only somewhat related to what you get off the press. I tried making a more red color and it does not works. It does not exist in the palette.

Passed a certain point, all reds in an area of the palette are the same. I don't really mind if it does not show correctly on the screen, as long as I get good results when printed. Quote: If its to be printed digitally, get go ahead and proof the RGB on a digital machine. Are you saying that some printers print as RGB? Actually, though most printers do indeed print in CMYK, they often have a larger color gamut can print more colors than a given dtp profile thinks it has.

For many color printing projects these days the printer will actually request RGB files that they can convert themselves. It still means that you need to pay attention to what might be out of gamut in your image convert to CMYK to see what radically changes, then undo and make alterations, or in a better program like Photoshop, use the gamut tools to see what's hot , but their printers especially digital printers can now often produce things impossible before.

When the file was converted to PDF, it actually got better. Much more close to the original. And when I print it, it printed like in the PDF. So I could finally get a texture which was red enough. So it's probably another bug of Corel Draw.

I am starting to get tired of these bugs. I'll probably wait for inkscape to mature before making the switch. Well, Corel draw comes with a PDF conversion tool. It's not perfect. For example, if there is too much pages or material in my file, the PDf file will crash before reaching the end. So I must print in PDF in multiple files and then merge them together.
