According to Joe Scout the first company to use CMYK in printing was Eagle Printing Ink Company and the year was 1906. It was not until 1956 that it became a standard as a result of Pantone trying to streamline the workflow.[1] This however does not really answer who really invented/discovered the choice of colors, the first scientific literature to ...

CMYK is an improvement over CMY which itself is improvement over RYB model, which has been used for centuries (if not millennia). It's really hard to tell where one ends and the other begins, especially as some use words "red" and "blue" in more general sense. Eg. George Field's chart from 1841 lists "red, blue, yellow" but his red in our eyes looks closer ...

There is no single definable point when the CMYK Process Colour printing was discovered. High fidelity process colour reproduction printing has been a gradual series of technical refinements. The persons responsible are, however, known. Printed colour reproduction grew rapidly in popularity in the late nineteenth and early twentieth centuries to today, ...

In 1906, the Eagle Printing Ink Company incorporated the four-colour wet process inks for the first time. These four colours were cyan, magenta, yellow, and black (also known as key), hence the name CMYK. It was discovered that these four colours can be combined to produce an almost unlimited number of richer, darker tones. Link: http://www.clubink....

Regarding the question I reset both of the monitors to their factory defaults, but still the issue persists. This does not help at all. The basic configuration is not on the monitor but in the graphics card that sends the signal to them. Here is a basic tutorial on how to (I repeat) give a basic calibration. http://www.otake.com.mx/Apuntes/...

Yes, some people (if not most) will definitely see your colors differently. And this is why we use calibrated displays when doing work for print because we can dominate the medium. Now most people will most likely see what your less expensive monitors show you (especially if its a wide gamut color monitor and not calibrated to sRGB!). To harmonize colors ...

Result of normal alpha blending is: Cout = α * CFG+(1-α) * CBG where CFG is the foreground color and CBG is the background color and α is the opacity. Thus you want to solve A from equation: B = 0.9 * A + (1-0.9) * CBG Which after manipulation is: A = (B - 0.1 * CBG) / 0.9 further assuming white color the formula per color channel is:...

Since screen technologies (contains phosphor that gets older), resolutions and configurations are so much different, that's a problem we simply cannot solve completely. If you have personal contact with customers, explain them how to calibrate their screen. And other tips here (help.adobe.com) How I faced this problem before (yes, I know it's very ...

Interpolating color works exatly the same as interpolating in space. It is just that the color space is a bit peculiar in general. Its not often very fruitfull to interpolate in RGB directly, though that works quite well if you use some kind of linear, piecewice linear or spline interpolation. It is often a good idea to interpolate in Lab space, or if you ...

why we should not do this. I would not say if you should or not. But you probably need to open your options. A brand guide preferably should be in an "absolute color" mode. A PMS is a good decision if the color matches de desired one. (I strugled a lot of years for a good red on the PMS system, sometimes I gave up for the red 032). But there are some ...

Colours are really perceptions, and are affected by other surrounding colours. In a colour you can also play with different characteristics, such as hue, saturation, etc, and in your case also with font weight, font size, etc. My opinion: I assume you will work over white or very light background. The best is to use a neutral grey for symbols (+, /, etc) ...

Just by looking at your formula I cannot tell what is important and what is not; perhaps before dealing with different colors your should differentiate levels of importance with different sizes. (forgive me the potato-quality image) Regardless of the colors used, it is easier to understand that the bigger elements are more important than the smaller ones....

Dashed strokes are effectively part stroke and part non-stroke (transparent). 2 possibilities for 2 color stroke: Duplicate the stroke, and group both together. Set the lower stroke in one color, and the upper stroke to dashed style, and another color. Use only 1 stroke, and set the stroke fill to gradient or (custom) pattern.

It likely depends on what you qualify as 'CMYK'. Other answers have already established that the K is superfluous -- it's there to make printing easy, not because it's required for color. So that makes us wonder who first established that we could create (most) colors using only three colors ... and I believe that at least in the West, that's credited to ...

On-screen representation is NOT an accurate representation of the final printed color. Even custom calibrating your monitor to get accurate color rendering will not always guarantee a match with the actual printed color. There is such a large difference between the way the color models are rendered, this makes using a monitor for color proofing difficult. ...

Yes and no. Always supply a version of the logo for use on dark backgrounds and a version for use on light backgrounds. But that doesn't necessarily mean inverting the colors. If the brand colors include a range of colors, some dark and some light then obviously you can use those for different versions of the logo, no need to extrapolate different colors. ...

Short answer—You can't. Forget about the RGB color, use a spot color or pick a new CMYK color, the RGB color you have doesn't exist in a CMYK color space. You should always be designing anything destined for print in CMYK. Related: Why do professional print houses use gamut-limiting CMYK?

Place the image behind the circle. Select both circle and image. Right-click and select Make Clipping Mask (or press cmd+7).

I don't think it is accurate to say that CMYK was "discovered". I am anything except an artist or an historian, so take what I have with a huge grain of salt. But, think about it. Ink is just paint for paper. Any question about ink must refer back to paint, and of course we've been using paint for 8 thousand years. So, the question is not productive. CMYK is ...

You need to change the colorization method to 'Exact': You can change the colorization method for all colors in the Color Reduction Options dialog by clicking the button next to the presets. Also make sure you have 'Recolor Artwork' checked.
