Printing & Prepress Basics Article @ Vectortuts

Vectortuts are having a graphic design tutorials & articles week. One article that I think is very important for graphic designers or anyone learning graphic design is how to set up your files for print like making sure your black is rich black.

Here's a brief piece of the article:

"Interestingly enough, there are actually several different types of black when it comes to printing, but the two most widely used terms are "plain black" and "rich" or "full black." Keep in mind, "rich black" has several variants, depending on your printer's preference. If you've ever created an image in Illustrator that contained sections of black, and later placed it into a Photoshop document where the image sat on top of a black you chose from the color palette in Photoshop, it's likely you've seen this disconnect.
Plain Black
When you use black in a program like Illustrator or InDesign without choosing a Pantone color, the CMYK breakdown automatically defaults to C=0 M=0 Y=0 K=100, where black is fully saturated and the other three are completely absent.
Rich Black / Full Black
As stated before, there are several variants of rich black, but what's important to know when you're designing is that the Photoshop default for black is different than other programs (where C: 75, M: 68, Y: 67, K: 90). It's likely that Photoshop will be the place you find this difference most often if you're not intentionally trying to give a piece of your design a darker, richer tone than you get with plain black.
If you are intentionally doing so, make sure to ask your printer which variant of rich black they like to use on press, usually referred to as "warm black" or "cool black," where there are higher levels of either magenta or cyan, respectively. It's generally not recommended that you use a completely saturated level of all four colors (where C: 100, M: 100, Y: 100, K:100), as this can over-saturate the paper on press and will certainly give the press operator trouble."
