“A forged or preground die used primarily on a clicker press. A clicker die is normally made in heights up to 1-1/4″ high with a blade thickness of 1/8″ or 3/16″. The blades are free standing with no center wood for support but may be reinforced with braces and have a backplate welded on to the dies so the die can be rubber loaded for ejection of diecut parts.”
CLICKER DIE PRESS
“A single arm press usually with a cutting bed@ up to 20″” x 40″” in size on which clicker dies@ bolted steel rule dies or ordinary steel rule dies are used. The name “”Clicker”” was derived from the clicking sound made by the mechanical action when the flywheel was released to initiate the downward cutting action on early non-hydraulic pressed like the USM ideal Clicker dating back to 1906.”

CORRUGATED BOARD OR CORRUGATED FIBERBOARD
The structure formed by gluing one or more sheets of fluted corrugating medium to one or more flat facings of linerboard. There are four common types: SINGLE FACE: Combination of one flute-corrugating medium glued to one flat facing of linerboard. SINGLE WALL: Two flat facings of linerboard, one glued to each side of a corrugated sheet. Also known as Double Face. DOUBLE WALL: Three flat faces of linerboard with two interleaved and glued corrugated mediums. TRIPLE WALL: Four flat facings of linerboard with three interleaved and glued corrugated mediums.
The machine that unwinds two or more continuous sheets of containerboards from rolls, presses flutes into the sheet(s) of corrugating medium, applies adhesive to the tips of the flutes and affixes the sheet(s) of linerboard to form corrugated board. The continuous sheet of board is then slit into desired widths, cut off to desired lengths, and scored in one direction.

(2) Also, a pre-made steel plate with all score channels etched or milled into it or a plastic piece with the individual carton scores milled in it. (3) Refers to the male portion of the tool. In the TEK-FLEX system this can be one of three types depending on the material and the customers needs.

A counterplate made of various base materials provides a base where creasing rules in a steel rule die match against machined grooves in the counterplate to create a desired crease in a diecut piece.
A selection of different plastic forms that math up with a creasing blade in a steel rule die to make a crease in the diecut part. Creasing Matrix materials adhere against the cutting surface and are excellent for short or medium runs of paper or paper board products. For long runs, a counterplate is more desirable.

“A cutting punch which has the end of the punch only slightly cupped out and is not a feed thru type punch. The purposes of this type of punch is to cut out a single ply of thin material and leave the slug in the diecut web. GENERAL RULE: The cup punch can only cut when the diameter of the punch does not exceed the thickness of the stock.”

In web printing, the cut or print length corresponding to the circumference of the plate cylinder and/or diecutter; repeat length.
A cutout is a portion of a die that cuts out an interior section of a die configuration. The cutout can be a permanent or removable cutout. A permanent cutout is constructed to always be in the die whereas a removable cutout is made so that if that particular cutout is not required in all diecut pieces, it can be removed from the die and later put back in the exact location.
In diecutting, a sharp-edge knife, usually several thousandths of an inch lower than the cutting rules in a die, made to cut part way into the paper or board for folding purposes. Cutting knives or rule that cut only partially through the stock for purposes of bending. Used when creases are not desired or in conjunctions with reverse cut scores to produce an opener detail.

A cutting pad is used in cutting and is made out of composition rubber, polypropylene or nylon in thickness up to 2″. The cutting pad is a replaceable item and when the cutting surfaced becomes worn in the diecutting process it must be surfaced to create a new cutting surface. It is recommended that a cutting surface be cemented to a metal or dieboard base to prevent the cutting pad from warping out of a flat condition.”
This refers to the amount of pressure that a cutting press exerts in the downward stroke of the cutting press. The pressure is normally identified in tons of cutting pressure. Generally a common rule of thumb states that it takes about 500 pounds per lineal inch of blade to accomplish a clean die cut, but that figure varies according to the material being cut and other conditions.
Cutting the scores in the counter into which the creasing rules must register to make the proper creases for folding.
“The surface against which the cutting die strikes after the die has penetrated the material being die cut. The cutting surface in the case of “”into”” cutting allows the die to slightly penetrate the cutting surface to create a clean cut and in the case of “”onto”” cutting the die strikes against or onto a hardened surface.”
In flexography most rollers in the printing press are called rolls with the exception of ones on which the rubber plates are mounted and the one which receives the impression. These are usually referred to as cylinders i.e. plate cylinder and impression cylinder.
