Films or films related to a floor filament (astrolon) incorporated into a film, making a mold or group film. This process is called assembly. The films were absolutely illuminated. These jobs are very easy in monochrome jobs. In multi-color jobs, the guidance "guide" works and assembly becomes more difficult. In the installation of multicolor works, the films belonging to the renge must sit absolutely on top of each other and without slipping.

Trase: "Printing Segment Chart"

It is a tool used as a base to perform the first color mixing. For this reason, it should be drawn carefully. It is drawn on a quality bristol cardboard or in metric paper. When we do this, a special lighting table (fixed iron scale) should be used. The division is made according to the number of jobs to be printed and the number of jobs. The lines are drawn according to the first escape.

Gluing films on ASTROLON

Movies; the mounting carrier "Astralona" is glued with transparent tape, parts without image and text. If there is a transparent band on "work", thin lines appear on the print. Special adhesives can be used instead of transparent tape.

Page layout in assembly

In the assembly of printed works such as books, magazines and catalogs, we give the name "assembly page distribution" for the page numbers to be correctly sprinkled once the pages have been printed and broken. The system is printing on the front and back of the paper. This printing is called "front side printing" - "back side printing". During assembly, the "scissor part" must be released and the scissors side must be marked. Since both sides of the paper are imprinted, it is necessary to turn the paper to print on the other side of the first side of the paper. This dial is 2 kinds.

Do not turn on the moon (Revolta)
It is a frequently used form of translation in printing. Front and back pages are in the mold. This system is applied for small sized press works. As both sides of the paper are pressed, one layer is cut from the middle and we get two "same" forms. It is imperative that the paper is well cut in this turning method. The "Page - Guide" changes when you turn it over. "Print - Guide" does not change.

Turning forward by twisting "skirt / scissors revolta"
The paper should be folded in such a way that the "paper edge" and the "page guide" will remain where they are and the "Print Side guide" will come one after the other. It is essential that the paper is well cut in this turning method (right angle).


Installation Errors

Care should be taken to ensure that the films are reversed or correct when assembled. The inverse of the films, ie the "emulsive" side, must be pointed at the sensitive layer plate when copying is done. Otherwise, it will cause spot loss in tramp works, as the film will pass the thickness of the light. A second mistake made during installation is the assembly of the single, single-mounted films in a limited picture, non-working parts. Since the films on top of it will shadow and these shadows will pass through the plate exactly, a new mold will have to be pulled. We know that a forman has 16 pages.

We can see how to organize these forms during assembly by making our own models. To make this model, take one A4 paper. I fold it in half and turn it into A5, then break it again and break it into A6 and break it again into A7. American skin and yarn stitching process is done with the form of the top is broken. In the case of binding made by wire stitching, this process is completely different. Since forms are nested within this binding system, the layout of page numbers is also different during assembly. Now let us see a three-form American skin-binding plan by folding three separate pieces of the same size, one A4 paper we made above.

In this assembly scheme, we will see that the places in the printing between the two bindings have completely changed and have taken a very different appearance. This is why it is necessary to specify the binding form when sending such a job to the printing press. After printing, wire stitching is not recommended as American skin or vice versa.
