In the Publishing and printing company "Sharq" works the department of prepress preparation.
We suggest you to download the file in which it is described how to prepare materials for imposition.
The list of the works preceding sending your order depends on degree of readiness of materials. The best option - file existence with a dummy, meeting the requirements of our printing house. But so happens seldom. For full compliance of the model of printed materials to requirements of production work of experts on prepress preparation (experts on Prepress) is necessary.
By preparation of editions for printing nonprofessional approach is inadmissible. It is very important to provide exact reproduction of work of the designer and technological subtleties of concrete production. Here work of the professional knowing features of the concrete printing equipment is necessary. Optimum to order design, prepress preparation and the press in one company which experts will be responsible for the end result at all stages of preparation. However in any case we move towards wishes of the customer. Working together with our clients, we prepare the polygraphies meeting their most different requirements for release of a product, we optimize already available models for creation of a printing product.
In modern printing houses texts are typed and edited on the computer. Illustrations are entered into it by means of the electronic device - the scanner. The received digital image often needs further processing - a retouch and color correction. After preparation of images for a look, allowing to receive qualitative printing products, carry out computer imposition of images: the page of future printing edition display on the monitor screen, place on it texts, schemes, drawings, photos - that everything turned out beautifully and functionally. The professional computer equipped with the program of imposition and the service equipment - the scanner, the printer, etc., is called as desktop publishing system.
Imposition is a prototyping component. Represents process of placement of text and illustrative blocks across the field of a format taking into account design of the model and spelling requirements.
By types of editions distinguish book, journal and newspaper impositions, each of which has features of technical and composite character. Imposition is carried out with use of publishing systems and supervised visually on the screen of the monitor of system or according to the firm copy received on the printer.
We carry out imposition of any models:
Magazine / catalog / brochure
Poster / poster / booklet
Newspaper / book
Calendar / folder / business card / form
At the request of the customer:
Editing of the ready model
Urgent imposition in the presence of the customer
Proof-reading reading of texts
Descent of strips for other printing houses
Numbering process of printing of changing numbers on a product. It is carried out by the special device - a numerator. In operational polygraphy allows to work with variable data, as surnames, series, etc.
Preparation of images
For ensuring the best quality of images at the press prepress preparation of images is carried out. These processes are made by means of special graphic programs. Preparation of images includes a retouch and color correction, as well as other processes of processing of images.
The retouch represents adjustment or removal (addition) of any elements of the image. For example, elimination of unnecessary details of the image, noise, composition change. Often it is necessary to resort to a retouch to clean defects of skin, a dust on model clothes. Distinguish a technical and art retouch.
The technical - hides material shortcomings (a dust, scratches, breaks).
The art - makes correction of a form, the invoice and other characteristics of the object (removal/addition of elements in photos, for example, it is possible to clean wrinkles on faces of people).
Orientation of the image program of editing can turn images at any angle or reflect specularly.
Filters and special effects are used for giving to the image of an unusual look. By means of filters the picture can be distorted unusually, stylized, visibility of a volume relief can be added, colors are changed.
Color correction - modification of color of the original. By means of color correction possibly reduction of color balance of the image to a natural look (for example, color balance of the initial image, before scanning) or to a look necessary for the press (thus probably radical change of flowers).
The reasons of application of color correction are insufficient or excess contrast of the image, a veil, image fading. It is also necessary to note color correction for the purpose of harmony introduction between facsimiles and design of the publication or the maintenance of materials, like photo printing process in photographic art. As well as any other method, color correction can be applied as the instrument of realization of a creative plan or wishes of the customer.
At the request of the customer:
• Color correction
• Drawing of catalog type
Coloring test - the image serving as a sample for reproduction of color at replication of a printing material. Coloring test production - obtaining the control color image of printed materials on any carrier (for example, on paper on which the main circulation will be printed). Distinguish analog (raster), gray-scale (digital) and screen coloring tests.
Analog coloring test
Carry out such coloring test on the special equipment. Initial material for an analog coloring test are color-splitted films. When carrying out a coloring test on the special carrier in turn bring paints of CMYK colors. The analog coloring test is less flexible, than digital, so can't consider any features of the press of concrete printing production However as practice of application of this type of coloring tests proves, it provides its big reliability and stability.
Very important role in correctness of carrying out an analog coloring test is played by professionalism of the specific person who is adjusting it, correctness of his actions and the accuracy of devices.
Digital coloring test
It can be made as with use of printers specially made for this purpose in structure of tsvetoprobny complexes, and with use of high-quality jet printers (for example, Epson Stylus Pro).
The digital coloring test allows to consider any features of the press of concrete printing production.
Screen coloring test
In this case as a sample of the image "picture" on the computer screen serves. The main advantage of a screen coloring test consists in its efficiency and the low price. However for use of such systems the printer has to possess special skills as the image on a print and the image on the monitor are perceived by the person differently.
Scanning - obtaining the digital image from paper sources (the photo, the magazine, the book and so forth) or films, by means of the special device - the scanner.
Quality of the scanned image is influenced by many factors: technical capabilities of the scanner, quality of an initial material. If the original indistinct, soft, bad quality, the quality image it is impossible to receive even with use of the most modern equipment. The received digital image often needs further processing - a retouch and color correction.
