Suppose I'm designing something for printing purposes. Then I need to stick with CMYK model. When ever I'm choosing color while designing, I'm setting color based on what my monitor shows me as CMYK. But Monitors don't work on CMYK. So, what my monitor showing is a conversion of that CMYK in RGB. After reading little bit, now I understood that CMYK and RGB are not exactly convertible and there are color always some differences. So, what I'm seeing is not the color I actually set.
Legal-size envelope. Lay the legal paper, printed side up, on a flat surface. Fold the bottom edge of the paper upward, creasing it across, 5 inches from the bottom. Use a ruler to make sure that the crease is exactly 5 inches from the bottom edge. This will leave the top 4 inches of the paper exposed.
To fold is to crease or bend something over so it covers part of itself. Before you put your clean sheets and towels away in the closet, you should probably fold them. Some people drop their clothes on the floor at the end of the day, while others neatly fold theirs. You can call the crease in a folded piece of paper or pillow case a fold too. There are several ways to fold, including to gently mix ingredients, incorporating them without stirring; and to drop out of a poker hand, laying your cards down on the table.
