The Art and Science of Printing

Printing has evolved into a fairly simple process of using just four pure colors to make nearly every color. With a few exceptions like a great Orange, these four are blended together to make your vision appear on paper. But how is it done?

What is a screen angle?

See the inset above. Each of the four colors has its own screen angle – Yellow 0°, Cyan -15°, Magenta +15° and Black at 45°. Where these screens overlap is called a rosette and this is your dot. When you look very closely at a magazine photo, you’ll see the rosettes. The varying size and intensity of the dots gives you the color. When screens misalign, it’s called out of registration and causes a color shift. When an image is rescreened, you can get a moiré pattern – it can be cool or extremely disastrous.

Where colors come from?

The blends above show what colors come from only up to two colors being used at a time. For example, when you add yellow to magenta, you go from pink to red. If you add black, you gain darkness. Adding cyan adds a bit of purple to the pink. When you print black, many times it uses all four colors – the reason you run out of color ink even when you’re only printing black and white.

What’s wrong with my colors?

By looking above, you can see how the amount of ink effects the colors. Discovering which one of your printer’s ink colors that’s not working properly is looking at what’s missing.

You’re trying to print Navy Blue but only Sky Blue comes out – check your magenta.

Trying to print forest green but light green prints, check your black.

Your printer’s test page can often tell you which color is not performing properly.

What now?

First step is to try another cartridge. That’s why I kept an old one sealed in a bag – a for quick test.

For toner cartridges, you can remove them and gently shake the cartridge. For some inkjet printers, you can take an alcohol wipe and clean the contacts and gently wipe the print head.

Blending hint:

You may notice how clean my blend looks. When you mix 100% of Cyan, Magenta and Yellow; you should get black but you’ll get a muddy brown. When you want to make a great blend, change only one of those three colors at a time. For example, with Magenta, you can add either Cyan or Yellow. Adding both will make mud. Let’s say you have a great purple, 80%C/100%M. You can reduce both down to 15%C/20%M and then add 100%Y – the decision is yours and the results beautiful.
