Some printing technologies continue to use stripped film, especially in silk-screen printing, although this is likely to change in the near-term. The digital product of this imposition software can be outputted to an imagesetter that creates a single, composed piece of film, or directly to a platesetter which generates a plate that can go ...
This never generates a spot plate. Instead it marks all of the plates that are there. The All color space can be used with a tint value between 0.0 (no mark) to 1.0 (full intensity). Generally, only 1.0 would be used. The name "All" might not be used in the user interface of a design program, especially outside English language speaking areas.
Prepress is the term used in the printing and publishing industries for the processes and procedures that occur between the creation of a print layout and the final printing. The prepress process includes the preparation of artwork for press, media selection, proofing, quality control checks and the production of printing plates if required.
A US plate block from 1972. Note the addition of a number for each color. This increased the cost of collecting plate blocks. That, plus the format change, discouraged many collectors. A plate block is a block of stamps from the edge of the sheet which shows the plate or cylinder from which the stamps were printed.

Software packages that can be used to design single pages can often be used to design entire printed sheets, sometimes by a process as simple as copy/paste onto a larger sheet. This is still in use, especially for low volumes of work, but a popular alternative is an imposition function built in, or added in, to the design tool.
Modern manufacturing processes allow for diverse styles of nameplate design. Nameplates can be two- or three-dimensional; made of various metals (aluminum, zinc), stainless steel or brass, human-made materials (e.g. Mylar or Vinyl polymers ) or injection-molded plastic; and thickness, color, and size can all be customized.
The plates, called stereotypes, are coated with ink, then pressed against a continuous roll of paper. Rotary letterpress printing was used in the mid-twentieth century to print most major newspapers. In offset lithography, the image is chemically applied to a plate, generally through exposure of photosensitive layers on the plate material.
