E is Emboss
The surface of a paper can have an embossed surface texture - for example, linen or felt. This is achieved in paper finishing with male and female steel, cylinder drums that have a textured surface. The paper is passed through or threaded between the drums to impart the finish with heat and pressure.
Embossing is also a printing process in which a design is stamped or pressed (embossed) into the paper to create a gorgeous raised surface onto a printed piece with a die. Often, the dies are heated. Embossing which simply stamps a graphic with no other additional color or decoration is known as a blind emboss. Embossing when combined with a foil is called foil stamping. When combined with printing inks, it is called a registered emboss. Embossing dies can be made of brass, magnesium or copper. Brass is best for long runs. Embossing is generally done after printing.

D is Duplex Paper
Cover weight papers that are produced by laminating together two different colored pieces of paper - usually of equal basis weight. The process produces stiff, durable cover paper that is heavy and strong with excellent printing and folding characteristics. Many duplex papers are available but custom duplexes can be mill ordered with time and run minimums.

C is for CALIPER
Caliper is the thickness of a single sheet of paper, measured in thousandths of an inch, mils or points. Caliper is measured using a micrometer, a device which measures minute thicknesses of paper by applying a static load for a set period of time. Consistency of caliper throughout a manufactured roll of paper is important. Increases or decreases in caliper can affect the extent to which the printing plate or blanket contacts the paper and affects printability and runnability. The thickness of a paper itself varies according to the basis weight desired or end-use considerations. Caliper can be reduced or increased at a variety of stages in the papermaking process. The  amount of pulp, dyes and sizing deposited on the wet end of the paper machine can be reduced or increased. The process of calendaring (rendering surface smoothness) can reduce the thickness of the paper.
