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.

Fold first 1/3 of the right side of the paper or the left side, whichever you think is most comfortable to you. 3  3. Fold the other side on top of the other.  4. Check to see if the folds are 1  equal. 5. Subsequently repeat the previous process of pressing the folds.
